Duct Smoke Detectors for HVAC systems

Fire and life safety systems are comprised of many components that must cohesively work together to save lives and protect assets. The importance of commercial buildings having custom fire safety plans and working with a company with the knowledge and expertise of compliance with all regulations is crucial. Included in customized commercial fire and life safety systems are duct smoke detectors that are placed in the HVAC system.  Oxygen feeds fire and an HVAC system can spread smoke, fire, or gas throughout a building.  Duct smoke detectors can detect a fire and save lives by shutting that down.

How Duct Smoke Detectors Work

Duct smoke detectors can detect if fumes or smoke are present in air handling equipment and if smoke or fumes are detected, they will close the dampers on the duct and will shut down the blowers and fans that circulate oxygen throughout the building. This prevents the fire’s distribution by removing the source of oxygen. In addition, there will be a visible and audible signal sent to the fire control panel.

Duct smoke detectors come outfitted with two alarms: a trouble condition, which can be triggered when there is a malfunction in the power running to the detector, and a fire condition alarm which detects smoke causing the alarm to be triggered. The implementation of these two alarms helps decrease the frequency of false alarms.

Do I Need Duct Smoke Detectors for My Fire Detection System Design?

The requirement for duct smoke detectors with HVAC systems is for airflows that exceed 2,000 cubic feet per minute. This includes commercial buildings that have multiple air handling systems if they share ducts with a combined design capacity that is greater than 2,000 cfm. The location of where duct smoke detectors are installed will depend on the governing codes in your area.

High Rise Security Systems, HRSS, provides fire safety consulting with fire and life safety experts trained in customizing integrated fire safety systems for your commercial building needs. Our experts are trained on National Fire Protection Association (NFPA) code requirements to ensure your commercial fire and life safety system meets all mandated regulations, such as the NFPA 101 Life Safety Code.

Duct smoke detectors should never be a replacement for area smoke detectors. In contrast, they should work together to complete your fire detection system design. Commercial buildings still need area smoke detectors to meet fire safety requirements because if the air-handling unit is not up and running, the duct smoke detector will not be able to detect smoke.

Inspection of Your Commercial Fire Safety Duct Smoke Detectors

Just like the rest of your fire alarm system, duct smoke detectors should be inspected by trained and licensed fire safety experts at least annually, or more depending on your property and business operations. HRSS includes comprehensive commercial fire safety system services which include inspection of your fire safety system to ensure compliance with all federal, state, and local regulations.

HRSS fire and life safety professionals are trained in conducting all required inspections on your duct smoke detectors. These inspections should include:

• Ensuring the smoke detector has no signs of damage, is unobstructed, and is firmly mounted to the duct
• Making sure there are no signs of damage to the circuit board
• Ensuring clear visibility of the control unit trouble signals
• Checking that the in-line filters are clean
• Checking that the sample ports are unobstructed, and the sampling pipe is conspicuously identified
• All sampling system fittings and piping are airtight and firmly fixed
• Checking that the remote annunciators are free of damage and in good operational order
• Ensuring there are no interferences in the smoke detectors vicinity affecting the duct’s airflow

In addition to inspections of your duct smoke detectors, there also must be annual testing and inspections of all fire alarm safety systems. These must be conducted by licensed professionals who are knowledgeable of all code regulations. NFPA Code 72 requires:

• Conducting testing of sampling tubes to ensure the airflow in the ducts will be properly sampled. All tests must adhere to the manufacturer’s recommendation for the specific make and model of the duct smoke detectors being tested.
• Testing to ensure the right pressure differential between the outlet and inlet tubes is within the allowed range as stated by the manufacturer.
• Testing the sensing chamber of the detector to guarantee smoke can physically enter the detector.

When conducting these tests, HRSS’ knowledgeable team of experts will alert the proper authorities to inform them the smoke alarm system is having maintenance and testing performed and will be temporarily out of service to avoid unwanted false alarms.

HRSS is fully equipped with the knowledge and experience to fully customize your integrated commercial fire safety system and perform all necessary testing and maintenance to adhere to NFPA regulations.  We offer quality UL-listed fire alarm equipment including duct smoke detectors from the best names in fire safety.  Contact our fire safety consultants today for a comprehensive consultation to receive the best commercial fire and life safety system for your needs.

Why Invest in Your Fire Prevention Plan?

Protecting your commercial building and assets from fire involves much more than just having a fire alarm and sprinkler system. The ability to maintain safety and security involves the cooperation of you and your employees, working cohesively to meet a common goal: fire safety and security. Creating a fire prevention plan for your business is the best and most effective way to meet this goal.

Unfortunately, fires affect thousands of people and companies each year, and the results are devastating. Fires result in loss of life, injury, building damage, and the loss of your customers’ trust. Creating an effective workplace fire prevention plan provides vital protection against expensive damage, injuries and fatalities to employees or residents and possible fines to your business.

Training Employees in Fire Safety is Key 

Many of us will never experience a fire while at work and take on the notion that these things happen to other businesses and other people. This is completely the wrong attitude to have when it comes to fire safety. When employees attend safety meetings with a disinterested and unengaged attitude, it not only affects the morale of the entire group but can also put people’s lives in jeopardy.

The best way to reduce these influences is to hold regular fire safety meetings and demonstrations. Doing this communicates to your employees the seriousness of fire safety and demonstrates that it should be taken seriously. Additional ways to keep your employees safe and informed on fire safety are:

• Ensure each employee is trained on how to use a fire extinguisher
• Reinforce that fire safety protocols are understood by all employees
• Employees who smoke should only smoke in designated areas
• Train employees on the correct way to store flammable materials
• Educate employees on keeping exit pathways clear
• Ensure employees have a firm understanding of fire alarm monitoring protocols

More Tips for a Commercial Fire Prevention Plan 

The following fire safety tips help ensure workplace safety and strategies to prevent fire damage as much as possible.

• Always have your company’s evacuation route easily accessible to employees. All employees should know where to find the company’s fire safety plan and what their evacuation route should be.  For example, employees located in upstairs offices should have access to an escape ladder that can be hung from a window to escape a fire if the stairs are inaccessible and should know how to use it.
• The Occupational Safety and Health Administration (OSHA) offers fire safety resources, including Standards, Hazards, and Possible Solutions, Additional Resources including training and education, and information on Workers’ Rights.
• The National Fire Protection Association (NFPA) provides leading information and knowledgeable resources on fire, electrical and related hazards, including a list of Codes and Standards that reflect changing industry needs and evolving technologies to help ensure safety in the workplace.

When creating a fire prevention plan, employers must make sure they are meeting all fire safety requirements issued by OSHA and NFPA. Speak with a commercial fire alarm and life safety specialist to ensure you are code compliant with all OSHA, NFPA, and building code requirements in your location.

Inspections of Electrical Equipment 

Faulty electrical equipment is a primary cause of hazardous fires in the workplace. These fires can quickly become unmanageable and can be the result of overloaded plugs, loose or faulty wires, or bad connections.

Having your electrical equipment regularly inspected by a commercial fire alarm specialist is the best option for keeping everyone safe. All employees should be educated on how important it is to keep equipment in good operating condition. Do not use broken or frayed electrical cords, and do not overload extension cords or outlets.

NFPA Fire & Life Safety Ecosystem: 8 Key Components

What is the NFPA Fire & Life Ecosystem?

In 2018, the National Fire Protection Association (NFPA) developed a framework, titled the NFPA Fire & Life Safety Ecosystem. This framework outlines and identifies eight components that, when working cohesively together, help to minimize the risk and assist in preventing loss, death, and injuries from electrical, fire, and other hazards. The key components are interdependent, if any of the components suffer a breakdown within the ecosystem, the result can be tragic.

After a tragedy occurs, the NFPA states the cause of the tragedy can typically always be traced back to a breakdown in the component(s) of the Fire & Life Safety Ecosystem.

The Fire & Life Ecosystem 8 Key Components

The 8 components of the Fire and Life Ecosystem include:

1. Government Responsibility

It is the responsibility of the Government to enforce both effective regulations and policies that boost and assist electrical, building, fire, and life safety. But it is the responsibility of the commercial building manager to make sure those regulations and policies are enforced and followed. The NFPA has stated that when you follow fire and life safety requirements, it has been proven to lead to a reduction in losses.

2. Development & Use of Current Codes

To keep the Fire & Life Safety Ecosystem functioning properly, commercial property managers need to stay informed on the most up-to-date standards and codes put forth by the NFPA. These standards and codes are continuously updated to indicate the evolving needs for safety. NFPA offers a complete List of NFPA Codes & Standards.

Advantages of POE Security Cameras

One of the most important benefits of having video surveillance in your commercial fire and safety system is the ability to detect dangers and take prompt action to protect your assets and save lives.  Most security systems today need an internet connection to function properly, which provides total connectivity to monitor the security of your property from any device. Additionally, internet connectivity provides numerous storage options and infinite access for viewing images in real-time.

The innovation of Power over Ethernet (PoE) security cameras allows businesses to retrieve their power and data from a single cable. This is a game-changer.

Why Choose Wired PoE Security Systems

People tend to choose wireless security and surveillance systems because they are simpler and less expensive to install. Choosing a wired security surveillance system such as a PoE over ethernet provides commercial buildings more flexibility, stability, and reliability. In addition to more reliable protection, PoE systems also provide many added benefits.

Benefits of Wired, Ethernet PoE Security Systems

Wireless security surveillance systems may seem more convenient and easier to install, but commercial security systems with wired ethernet connectivity provide many advantages. The benefits of having a wired video surveillance system are extensive, and Power over Ethernet (PoE) systems are enhancing those benefits, which include: 

• Superior surveillance video resolution
• Higher quality surveillance
• Options for remote power
• Straightforward management
• Speedier data transmission
• Adaptable scalability
• Better reliability without unexpected downtime

Having a security system that does not look for or broadcast a signal is safer and more efficient for commercial security as they are:

• More difficult to hack
• More difficult to tap
• More dependable
• Less vulnerable to interferences

Connecting PoE cameras and recording stations to wired, ethernet data transmission is more dependable than wireless systems that can experience glitches in connectivity.  Wireless equipment can become disconnected much easier, which leaves buildings unprotected.  Even a short period of non-connectivity for security equipment leaves buildings and people at risk.

PoE Security Cameras Do Not Require WiFi

IP cameras, such as PoE security cameras, refer to standard wired security cameras that require the internet to transmit video surveillance and data transmission.  PoE cameras communicate with users with an Ethernet cord to transmit and collect data without using WiFi. This proves to be much more reliable than devices that search for a wireless signal and can go down if the WiFi signal goes down.

Wired Video Surveillance Systems: Reliable and Convenient Security

PoE cameras for commercial fire and life security systems allow electrical connection coupled with data connection using one single Ethernet cord. What this means is a single cord can provide an IP, wired, or PoE camera security system with all necessary elements to be entirely functional.

The need for a second cord carries the stigma of requiring more time, money, and hassle for your commercial video surveillance and security system. PoE cameras give you all the power and versatility your security system needs with a single cord.

Thanks to the introduction of PoE security cameras, wireless security systems no longer provide the less expensive, easiest, and faster choice for installation. Furthermore, wired commercial security systems can deliver convenience and user-friendly options for your security needs.

PoE Security Systems: An Important Part of Integrated Security

Businesses look for security systems that are fast, safe, and can meet their commercial security needs. PoE security systems are the fastest and safest on the market today that deliver adaptability and scalability both outside and inside commercial structures.

PoE camera security systems can reach distances from 100 – 300 feet and 100mb/s, making them the ideal option for commercial businesses looking for a new security system. High Rise Security Systems, HRSS, prioritizes the safety and lives of your occupants by providing commercial fire alarm and life safety systems, including all-inclusive video surveillance security systems.

Fire Alarm System Design

Commercial fire alarm systems are the most critical piece of protecting a company’s most important assets and saving lives. Fire alarm systems play the most significant role in how well your property and the building is protected in a fire emergency and can be the difference between life and death for occupants.  It is necessary to work with a licensed, professional fire alarm system designer to ensure that your commercial property is protected and compliant to all fire safety and building regulations. 

Commercial business owners cannot go down to the nearest big box store and buy a couple of smoke detectors like you can for your home. Having a certified professional on board could mean the difference between saving your business or experiencing huge losses, including loss of life.

Commercial Fire Alarm Design is Complex

Many important considerations go into designing a commercial fire alarm system, which involves creating an elaborate system of wiring, equipment, and dozens of additional components.  Proper placement of detection devices, initiating and notification devices is required. Additional fire safety features such as communication devices, mass notification systems, and sprinkler systems may also be integrated with your total fire, life, and safety system. 

Additionally, fire alarm systems are governed by a rigid collection of codes and rules from local, state, and federal building and safety regulations designed to keep property and, most importantly, people safe. 

Commercial fire alarm system design should only be performed by an experienced fire alarm system designer with in-depth knowledge of all code regulations. A professional fire alarm system designer will also consider how many floors the facility has, its construction materials, its composition, the number of exits, and heat sources. A fire alarm design engineer will consider these many aspects and more.

Regulations Govern Commercial Fire Alarm System Design

Regulations governing fire alarm systems vary from state to state, however, many are modeled after NFPA 72, which details the performance, location, application, maintenance, testing, and inspection of fire alarm systems. The professional designer will also be able to interface with the Authorities Having Jurisdiction (AHJ), usually the fire department, to see what control they have over the process. 

In addition to codes and regulations, there are several other conditions that must be considered when designing a fire alarm system. These include insurance company requirements and unique building codes beyond the fire alarm codes. Additional considerations may apply to older buildings, such as the Americans with Disabilities Act (ADA).  An experienced fire alarm system designer will also consider your unique building architecture and business operations to go above and beyond code compliance to provide maximum safety and protection. 

Commercial Fire Alarm Design: Considerations Beyond Saving Lives

Keeping people safe is always the primary goal of a commercial fire alarm system, although additional considerations benefit business owners.  Business owners and building managers have other requirements that a professional fire alarm system designer can integrate into the final design. These goals could include: 

• Ease of maintenance 
• Fewer false alarms
• Longevity of the system
• Ability to accommodate future changes

Fire Alarm Technology Continually Evolves

Building managers have many choices regarding modern technology that could help them meet their fire and life safety objectives. Wireless fire detection permits monitoring in areas that previously were prohibitively expensive or physically impractical to monitor. 

• Remote monitoring and control methods now provide extremely early fire detection and the ability to locate where in the facility the fire is taking place so firefighters can arrive fast and at a pinpointed location. 
• Sensors can tell smoke and fire from other obstructing indicators, such as dust and steam, which can trip a false alarm. 
• Some detection systems now can give maintenance alerts concerning specific smoke detectors saving time and money hunting a problem down.

When dealing with a commercial building containing property and people, facility managers should cut no corners in selecting a professional to design a commercial fire alarm system. In case of an emergency, the money invested will be well worth it. 

HRSS is a top designer of commercial fire alarm systems, with engineers knowledgeable of proper placement of all detection, initiation, and notification devices for code compliance. Our experienced fire safety engineers utilize AutoCAD systems and work closely with all interested parties throughout the planning and design processes. Contact us to learn more and to ensure that your fire alarm system design addresses all essential considerations.

The Purpose of Duct Smoke Detectors

During a fire, the ducts of an HVAC system can serve as a literal superhighway for smoke, carbon monoxide, and carbon dioxide throughout a commercial building. In addition, the airflow from an HVAC system feeds a fire oxygen, supercharging the process. It is essential and may be required by commercial fire alarm code regulations to have a functioning duct smoke detector in your building. 

How do Duct Smoke Detectors Work?

Duct smoke detectors test air currents to determine if fumes or smoke are present in air handling equipment. The detection system will stop blowers and fans, close dampers, and trigger a visible and loud signal at the fire control panel if anything is detected. Code requirements may vary based on the governing code in your jurisdiction, however, duct smoke detectors are most common in buildings with 5-ton plus HVAC units, if 2,000 cfm (cubic feet per minute) or more are processed through the supply side of air handling units, or if the return side exceeds 15,000 cfm and serves more than one building floor. 

A duct smoke detector is a perforated pipe affixed to a smoke detector. The pipe extends into the duct and is placed so that duct airflow passes through it. The pipe then pushes the air it gathers into the smoke detector. A return pipe moves the air back into the duct.

Duct smoke detectors are connected to a circuit board. The detector notifies the circuit board when the airflow sampling process identifies smoke. The board then sends a signal to activate the fire alarm, which shuts down the HVAC fan, and damper closure begins.

Maintenance is Very Important for Duct Smoke Detectors

NFPA 72 states that duct smoke detectors must be visually inspected twice per year. These inspections should be performed by qualified staff or a trained fire safety professional. It should ensure the following: 

• The Circuit board has no apparent signs of damage
• Remote annunciators are working properly
• Airflow through the duct near the detector is not affected by any holes or cuts 
• Trouble signals on the control unit are clear
• Sampling system fittings and piping are airtight 
• The sampling pipe is marked in a visible spot, and samples are clear of debris
• Filters are clean
• The detector is securely mounted to the duct and shows no damage  

Like all commercial fire alarm systems, duct smoke detectors must have an annual inspection and testing performed by a qualified fire safety professional. NFPA 72 requires the following steps for duct smoke detectors:

• A test to make sure smoke can enter the sensing compartment of the detector
• A test to verify that the pressure differential between the sampling pipes is within the manufacturer’s specified range
• Sampling pipe testing to ensure that the duct airflow follows the manufacturer’s recommendation 

Fire alarm technicians may use compressed air, a vacuum cleaner, or dry nitrogen to remove debris and dust if sensors require cleaning. The proper local authorities should be notified the system will be down when the testing takes place. 

Duct Smoke Detectors Important Part of Commercial Fire Alarm Systems 

A duct smoke detector is an important part of many commercial fire alarm systems. If the HVAC unit is not working, the duct smoke detector will not detect smoke by design. Duct smoke detectors should be considered another component of a comprehensive fire and life safety system. A commercial building still requires area smoke detectors to meet local, state, and federal fire safety regulations. 

Duct smoke detectors are an excellent investment in protecting your people and property and provide added protection in a building where regular smoke detectors either may malfunction or were not maintained properly.

HRSS provides high-quality commercial fire alarm system equipment from the leading manufacturers in fire safety.  We offer advanced fire alarm systems that monitor safety conditions throughout a building or complex with quality fire alarm equipment, including detectors, initiators, visual and audible alerts, and remote features with full integration.  Contact us to learn more about when and where duct smoke detectors are required in your commercial fire alarm system.

Why Elevator Recall is Important

 An elevator recall ensues when a fire alarm system triggers and commences to automatically send the elevator cab and its occupants to the building’s primary or pre-determined floor. If the smoke detector that set off the alarm is on the primary floor, the elevator will recall to an alternate floor. 

Keeping People Safe is the Primary Goal

The idea is to get people in the elevator to safety as quickly as possible. Elevator shafts can fill with smoke and fumes exceptionally quickly in a fire emergency. A recall also tells firefighters that fire could be in the machine room or shaft and to not use it.

Since elevators require inspection and testing of recalls, it is critical for building managers to educate themselves on the fundamentals of the process.

Maintenance and Testing are Critical 

For a facility’s elevator to receive certification, it must go through annual testing and inspection of elevator recalls, among other things. Trained elevator and fire alarm technicians should be the ones to test how the recall functions.  Both the Authorities Having Jurisdiction (fire department) and the local elevator inspection department are tapped with administering the regulations.

There are varied code requirements, including the Chicago Building Code, International Building Code, standards issued by the National Fire Protection Association, and more affecting businesses in and around Chicago.  This makes it complex to understand which regulations apply to your company and your property.  Working with an experiencedfire alarm and life safety professionalwill ensure that your elevators are tested and properly maintained.

The Regulations That Guide Elevator Recalls

There are general regulations found in NFPA 13, 70, 72, 101, and ASME A17.1 that detail the requirements for elevator recalls and fire alarm systems. 

Here are a few highlights:

• Smoke detectors are prohibited in the shaft without sprinklers.
• Just heat detectors may be acceptable in a parking garage elevator lobby where smoke detectors may not be required. 
• Only automatic detectors located in elevator shafts, elevator lobbies, and machine rooms are permitted to initiate the recalling of elevators.  An elevator should never be recalled by a manual pull station or by detectors in other facility areas unless specified by the AHJ.
• Many older fire alarms comply with code and may be appropriate for elevator recall, while some systems may require an upgrade of fire alarm technology. 
• Many fire departments may mandate a complete overhaul of the building’s fire safety system to achieve code compliance. 

A building manager’s essential function in fire alarm system and elevator recall testing is to organize the process and its multiple moving parts. Scheduling a time for the testing and inspection that works for fire alarm and recall technicians is a big part of the role. 

After hours when few or no tenants are in the facility is the best time to test and inspect elevators. Businesses should notify occupants in advance of the testing. Posting signs that indicate necessary testing is occurring and not just “out of order” will help avoid some frustration and let occupants know you are working for their safety.

High-Rise Condominium Fire Safety

High-Rise condominiums have received much attention in recent years from the fire safety community. The multiple floors of a high-rise building require many residents to venture a long path downward from their homes to evacuate, making them especially tricky from a safety standpoint. 

A well-known example of a tragedy in a high-rise residential setting is the Grenfell Tower fire in London in 2017, which killed 72 people because of a lack of fire monitoring and safety precautions. Consequently, condominium managers and owners associations (COAs) must always be genuinely vigilant about fire safety. 

Fire Alarm Systems are Mandatory

Buildings are legally required to have a working and tested code-compliant fire alarm system. As a condo manager or COA, you should also:

• Consult with a fire protection company to find out what type of sprinklers, smoke alarms, and extinguishers federal, state, and local laws and codes require and where to install them. The National Fire Protection Association (NFPA) Standard 13 dictates regulations for sprinkler systems.
• Have residents tailor their own escape plan, including exit routes, whether the front door or designated fire escape.
• Make sure shared areas such as laundry rooms, recreational facilities, and meeting rooms have smoke detectors and are free of electrical issues. Regular testing and maintenance are critical. 
• Constantly educate staff and residents about fire safety in high-rise buildings. Here’s a link to an informative brochure compiled by FEMA on High-Rise Fire Safety.
• Appoint employees and residents to a committee that meets and discusses fire safety at least two times a year. The committee should distribute information and minutes to residents. 
• Create a condominium fire safety checklist. 
• Clean and organize storage areas.
• Stock flammable materials in the correct places.

Additional Condominium Fire Safety 

Condominium managers and COAs should make sure there is a fire extinguisher on every floor as well as any basements or parking garages. Also, establish a community meeting area once people evacuate the building so residents can account for each other. Although nobody likes them, it is a facility manager’s responsibility to conduct fire drills at least once a year so residents are well-versed on the plan should an emergency occur.

Create a Fire Safety Plan for Residents

It is critical to create a fire safety plan that is unique to your condominium regarding layout and residents with disabilities. In addition to some of the things referenced above, your safety plan needs to have condominium building info such as construction type, evacuation, fire safety tips, and info on the building’s fire safety system. Managers and COAs should: 

Provide each resident with one
Post it in common areas
Distribute copies to each new resident
Make sure the local fire marshal and the fire department have a copy of the plan

Keep in mind, some factors can exacerbate a fire emergency. These should be considered in any fire safety plan. They include: 

• Insufficient water supplies
• A breeze creating a wind-driven fire 
• Elderly occupants with a lack of mobility
• Occupants who panic

Space Age Carbon Monoxide Detectors for Ductwork

In commercial buildings, carbon monoxide (CO) detectors placed throughout ductwork are the best way to avoid CO poisoning, keep tenants or residents safe, and preserve lives. Carbon monoxide detectors are sensors that respond to CO and are attached to an alarm unit. These detectors and sensors generally comply with ANSI/UL 2075 Standard for Gas and Vapor Detectors and Sensors. 

CO detectors can be used as a single unit system or integrated with a security or fire alarm system. This integrated system notifies first responders of a CO emergency. Some state codes mandate one detector should be placed every 100 feet of ductwork. 

What is CO?

Carbon monoxide (CO) is also known as a “silent killer” because it is an invisible, odorless, tasteless, colorless, and non-irritating gas that can cause significant health problems including death, quickly. When ingested, CO inhibits the body from absorbing oxygen. The U.S. Centers for Disease Control and Prevention (CDC) estimates about 430 people die from accidental CO poisoning in the United States annually. In addition, more than 20,000 are injured or become ill from CO poisoning. 

Symptoms include fatigue, nausea, dizziness, and headache. These symptoms imitate flu symptoms or other illnesses, and that’s why CO issues can be confused for different sicknesses. 

Sources of Carbon Monoxide

If a commercial HVAC system is inefficiently operating and deficient oxygen is in the air, and the CO level is too high, you will have problems. That’s why it’s crucial to ensure your commercial building has a carbon monoxide detector installed by a trained professional. A sensor can indicate rising CO levels and save employees, occupants, and visitors before permanent damage.

There are many potential sources of CO in a commercial building: 

• Gas-fired dryers and washing machines 
• Gas-fired ranges and ovens found in cafeterias, commissaries, and kitchens
• Use of gas-fired power tools inside a facility 
• Running vehicles inside a parking garage or loading dock 
• Gas-fired boilers and water heaters
• Heating systems

UL Listed, High-Tech CO Detectors 

Several carbon monoxide detectors for ductwork on the market today provide very early detection in the air circulating through a commercial HVAC system.  They are outfitted with a UL-Listed electrochemical sensor that alerts at certain PPM carbon monoxide levels mandated hazardous by OSHA and the NFPA. Most COsensors have a life span of 6 to 10 years from the manufacturing date. But this number might vary depending on environmental conditions; low relative humidity and high temperatures can dry out sensors. Wet, humid conditions can also be problematic. Often, historical information can be recalled from the detector to help in identifying the source of a CO issue or leak.

Other features available from today’s commercial detectors:

• “Snap-in” sensors that are easily removed at the end of life
• Test mode for an aerosol test of CO 
• Self-test initiated every day
• Connectivity to other units
• Internal dust filtering by sensors
• Fire alarm system compatible
• Wiring instructions affixed directly to the unit

Integrated CO Detectors Provide the Greatest Value

The cost of purchasing and installing a CO detector depends on the type of unit and warning system. CO detectors can be installed in single or multiple locations, and integrating them with your commercial fire alarm and life safety system provides the greatest value. Integrated detectors can send signals to an outside station ensuring constant monitoring, instantaneous notification, and immediate response.

Mass Notification Systems Explained

This article was published on  3/2/2018   and updated on  5/3/2022

A Mass Notification System (MNS) is also known as an Emergency Communication System (ECS) and is much more than a fire alarm. An MNS is used to deliver audio messages to alert all occupants of fire and non-fire emergencies and should direct occupants with proper instructions such as evacuation procedures, or shelter in place commands depending on the emergency.

A risk analysis for a Mass Notification System should be conducted by an experienced mass notification system designer as required under National Fire Protection Association, NFPA, fire alarm and life safety standards.

Origination and Purpose of Mass Notification Systems

The MNS was originally popular and widely used in military occupancies to broadcast messages quickly inside and outside of buildings on a base, with the technology becoming a launching pad to MNS in non-military applications. Mass Notification Systems aim to prevent mass casualties in commercial, public and government facilities including offices, hospitals and school campuses. The goal of any MNS is to provide real-time instructions to groups of individuals during emergencies such as:

• Severe weather and natural disasters
• Fire or hazardous material release
• Active shooter situations
• Terrorist attacks
• Child abduction
• Hostage situation
• Traffic accidents and alerts
• General information

The design of an MNS may consist of three distinct phases including:

• Identification of the need for an MNS and evaluation of the applicable rules
• Design phase with an entire team working together for a successful, integrated system
• Testing of the MNS and proper acoustics in all areas

Components of an MNS

The main components of a mass notification system are determined during the risk analysis and design phase. The components of an MNS include:

• Notification network
• Control unit
• Part of an integrated fire and life safety system
• Multi Zone audio systems for localized announcements
• Text to speech translation capability
• Video monitoring
• Weatherproof construction of outdoor elements
• Remote access to deliver notifications while off-site

Code Requirements for Mass Notification Systems

According to the most recent edition of NFPA 101, Life Safety Code, a fire and life safety system designer must perform a risk analysis prior to designing a Mass Notification System. This requirement has also been present in NFPA 72, National Fire Alarm and Signaling Code.

The United Facilities Criteria (UFC) 4-021-01 Design and O&M: Mass Notification Systems is a publication by the U.S. Department of Defense (DoD) and outlines the criteria for Mass Notification Systems in DoD facilities. The MNS must have the means to timely notify occupants of immediate threats with explicit instructions on how to respond including from prerecorded messages and the ability to give live, audible emergency messages for notification and evacuation procedures.

NFPA 72, 2022, Edition, Chapter 24, details the code requirements for Emergency Communication Systems including the application, installation, and performance as well as inspection, testing, and maintenance requirements. Chapter 24 goes into detail regarding intelligible voice messages, loudspeakers, microphone use, and ancillary functions. The system should be defined as one-way or two-way communication, with the ability to prerecord automatic emergency messages that should be identified and developed for each scenario identified in the emergency response plan.

NFPA 101, includes Figure 7.8.2(k), an Emergency Communications Systems Supplementary Record of Inspection and Testing as a guideline. A risk analysis is required based on the listed occupancies such as for a high-rise building, and educational building or campus, mall occupancies and more.

In addition to NFPA 72 and NFPA 101, a risk analysis may be required by other code regulations such as the International Building Code, IBC, or the Chicago Building Code, CBC. Both NFPA standards are clear in that an MNS is not expressly required for campuses or facilities, but rather provide information so that the owner can make an informed decision. When an MNS is provided, as is typical with any code it must meet the requirements of NFPA 72.

Facilities may also be required to meet regulations according to the Americans With Disabilities Act (ADA), Occupational Safety and Health Administration (OSHA), and FEMA’s Outdoor Public Alerting System.

NFPA 3000, the Standard for an Active Shooter/Hostile Event Response (ASHER) Program, addresses an integrated preparedness, response, and recovery in response to the increasing number of tragedies involving active shooter and hostile events. NFPA 3000 addresses all aspects of the process such as identifying hazards, assessing vulnerability, resource and incident management at a command level, vulnerabilities, competencies of emergency responders and recovery.
