Fire Alarm Functional Testing Checklist

Jan 02,  · Testing a Commercial Fire Alarm System 1. Notify your fire department if necessary. Many commercial fire alarm systems are directly connected to your local 2. Activate your fire alarms. 72%(55). May 23,  · Ryan Fireprotection is normally called in to handle the more intensive annual fire alarm testing. The following is a checklist of the top 15 items that we test on annual inspections. For the Control System and Transponder, the following are checked.

Fire safety is essential — nobody doubts this. Some people believe that a well-designed system straight from the manufacturer is sufficient, but unfortunately, it is not. Commercial fire alarm systems need regular testing and maintenance to perform properly and protect the people and assets you care about most. Experience shows that the most common problems with smoke detectors and fire alarm systems are battery drain, dirty or failed detectors, false alarms, ground faults, failed relays, and horn or strobe failures.

The table below outlines each of these issues along with recommended testing and maintenance for them. Most jurisdictions require commercial fire alarm systems to be tested and inspected on an annual basis in order to maintain a certificate of occupancy.

While you could take the time to learn about these systems, many businesses choose to hire a professional to properly handle all fire alarm maintenance. Professional organizations who regularly inspect fire alarm systems have test equipment specifically designed for alarm inspection that can cost tens of thousands of dollars.

Additionally, they employ a trained staff with certifications in fire alarm installation service and maintenance like those of NICET. In addition to fire alarm systems, suppression systems, sprinkler systems, and fire extinguishers should be inspected and tested on a regular basis. Any failure from a fire alarm is one too many. Commercial fire alarms are much more complex than their residential counterpart and require a greater deal of care, so many organizations turn their testing and maintenance over to a professional, like the Fire Safety Specialists at TSG Security.

A properly designed fire alarm system meets the requirements for standby how to make cats breed in minecraft capacity. Typically, battery size is calculated to allow the fire alarm to be without power for a specified period of time and then be able to sound the alarm for a specified period of what does kabhi khushi kabhi gham mean. Batteries need to be tested under load.

Specialized battery load testers should be used to test battery how often to do bench press. The typical lifespan of a sealed lead acid normally used in fire alarm applications is years. Batteries should be labeled and dated when installed or replaced. Detectors Smoke, Duct Dirty detectors cause false alarms, especially in areas where there is a high percentage of airborne dust particles that can settle and collect on equipment.

Duct detectors are more susceptible to dirt collection. Changing filters in HVAC equipment often causes new patterns of air circulation that can cause dust to settle on duct detectors. Smoke detectors in relatively open spaces can at times become dirty as well depending on the environment and air movement.

Some intelligent fire alarms report individual detector sensitivity obscuration percentage. In systems where device sensitivity is not available through the panel, specialized equipment may be required to properly test detectors to determine percentage of obscuration. Using forced air for cleaning detectors is generally not recommended as it may damage the sensors.

Light vacuuming is generally acceptable. Some detectors have a removable chamber that can be washed out. Heat Detectors Thermal element sensitivity declines over time. Heat detectors are often installed in dusty or otherwise dirty environments. Rate of rise detectors can have ports that get clogged and lessen the detectors ability to sense heat.

Testing depends on type of heat detector. Rate of rise detectors can be tested by simulating a heat source. Once a fixed temperature device is actuated by applying heat, it must be replaced. Keep heat detectors clean and never paint them. Don't have time to read this article? Download the PDF. Posted on March 1, Categorized as Featured Fire Safety Services.

Batteries drain over time and become insufficient to power the system in normal or back-up mode. Dirty detectors cause false alarms, especially in areas where there is a high percentage of airborne dust particles that can settle and collect on equipment.

Thermal element sensitivity declines over time. Ionization type smoke detectors are designed to detect fire in its earliest stage when smoke particles may not even be visible. For this reason, ionization detectors are generally more sensitive to dust particles and air movement, creating the opportunity for false or nuisance alarms. Ion detectors cannot be effectively cleaned and thus should be replaced upon failure. If there are a significant number of false alarms, then it may be advisable to change or reposition the detector.

CO detectors should be inspected for date and if still within safe range, tested for operation with canned CO. Ground faults occur when an exposed wire touches a metal grounded object or becomes pinched. Ground faults occur over time due to structural shifting, water damage, and construction changes.

Ground faults are generally reported to the main fire alarm panel. Some older systems do how to bead a bracelet instructions monitor the circuits and thus there is limited ability to detect problems. If the ground fault is constant locked inthen it is possible to isolate the problem and repair the wiring in that area. More often than not a ground fault is intermittent.

Isolating and repairing an intermittent ground fault can be challenging. The condition that caused the ground fault may not be present when you inspect the circuit.

The only option is to inspect the entire circuit and look for any obvious signs. It can take several attempts to locate an intermittent ground fault and it can occasionally be more cost effective to replace the entire circuit. Relays in fire systems control fire doors, magnetic emergency door closures, air dampers, and elevators. They are constantly working inside of the electronics, storing and releasing charged energy, and may fail to operate over time due to wear from opening and closing.

Testing of relays is done by activating an alarm and inspecting for proper operation of all auxiliary functions. Warning horns and strobes are susceptible to electronic failure due to age and deterioration. These devices are constantly receiving signals from the associated notification circuit which can lead to wear of internal electronic components.

Testing of warning horns and strobes is done by activating an alarm and inspecting for proper operation of these devices. Often as buildings are renovated notification appliance circuits are changed or devices are added.

These changes to the system can unknowingly cause devices outside the construction area to fail or be underpowered due to the additional circuit length or current draw. Commercial fire alarms require periodic software and firmware updates to correct issues discovered over time.

Commercial Fire Alarm Concerns and Recommendations

Mar 01,  · Anytime the fire alarm system is worked on the minimum acceptable level of testing is % of the area of work and 10% of them are outside the work area. Outdated Software: Commercial fire alarms require periodic software and firmware updates to correct issues discovered over time. Update the software periodically with annual fire alarm system testing.

Learn more Fire alarms are essential safety devices that, when activated, will alert you of danger and quite possibly save your life.

Testing your system regularly ensures that the detectors and alarms are working properly and will operate as intended during dangerous situations. To see if a smoke detector has enough power, press and hold the test button located on the front or back of the device. You can test the particle detector by spraying a can of Smoke Test aerosol near the alarm. To check if the smoke detector works, ignite 2 or 3 matches below the device and blow them out immediately, letting the smoke rise to the detector.

If the alarm does not activate after any of these tests, your device may not be operating correctly. For tips on testing a commercial fire alarm system, read on! Did this summary help you?

Most models look like small, white discs with a single LED light on the top or side. Most alarms require you to jump up and down before you press the test button.

If they were properly installed, you should not find any detectors near doors, windows, or air ducts. Go to source. Check the power by pressing the test button. For some alarms, this may be as simple pressing and holding a button on the hood of the device. For others, you may need to unscrew the device from the wall or ceiling and press a button on the back of the device.

If the alarm goes off, the device has enough power. Go to source Before finishing your test, walk away from the alarm to see how loud it is. If you cannot hear the alarm in the next room over, it may not be loud enough to keep you safe. For modern devices, testing the power will also test the particle and smoke sensors, making further tests unnecessary. Spray aerosol to check the particle sensor. Following the instructions listed on the can, spray the aerosol close enough to the smoke detector that it can pick up the particles.

Then, if it is still dirty, clean the device with a soft cloth or brush. Light matches to check the smoke sensor. Blow them out immediately and let the smoke rise to the detector. If it does not activate, your detector is not operating correctly. After the test, suck up the smoke with a handheld vacuum. If the detector is dirty, clean it with a brush or soft cloth.

Reset your alarm after each test. Once each inspection is complete, you can turn off the alarm by holding down the Test button for around 15 seconds.

This will reset the device and allow you to proceed with the other tests. For battery-powered detectors, simply remove and reinsert the battery pack.

For hardwired detectors, disconnect the detector from the wall and remove any backup batteries. Then, reinsert the batteries and reconnect the device. If the alarm sounds off immediately after reconnecting the power, your device may be malfunctioning.

Method 2 of Notify your fire department if necessary. Many commercial fire alarm systems are directly connected to your local fire department, meaning that as soon as the alarm goes off, it sends out an emergency distress signal. Activate your fire alarms.

For some fire alarm systems, you may be able to activate the alarms directly from the control panel. For other systems, you may need to activate the alarms manually, typically by opening an alarm lever box with a master key and pressing the button located there. Examine all your alarms. While the test is active, walk around the building and check each alarm.

In addition to the alarm simply turning on, make sure the sounds coming out of the device are loud and any strobe lights located on the device are active. Record your results. While checking your fire alarm system, keep a list of every individual activating device and how it reacted to the test. If one or more alarms are faulty, this information will help a technician locate the problem quickly.

This is particularly important for large institutions with dozens of different alarms. However, you should still check the alarms in person to make sure the reports are accurate. Reset your alarm system. To reset your fire alarm system, go to your central control panel. Inspect your detectors regularly to adhere to NFPA 72 regulations.

You should have sprinkler systems examined twice a year and all other devices inspected annually. Go to source If you do not have a fire alarm technician on staff, search online for a local engineer or technician that specializes in fire alarms.

NICET allows you to search local engineers by name to see if they are certified. It depends what state or country you're in as to whether your local fire department gives them out.

In most places you'll either need to buy your own or have access to a government-sponsored concession program. You may live where the fire department will come out to fit it or check it's properly fitted, if they have spare time.

Call to find out. Not Helpful 0 Helpful 1. Upnorth Here. In theory, simplex pull stations can be "tested" by putting the alarm system in "test mode" to prevent signalling the emergency response and pulling the handle to activate that pull station.

Some places do this by rotating which pull station gets tested during routine fire drills. Not Helpful 0 Helpful 0. There is no international standard for that. Also, there may be flats with both an alarm system and individual alarms within each unit. Alarm systems are not always required e. Self-contained smoke alarms in residences should be tested according to the manufacturers' recommendations -- typically once per month. Commercial alarms may need additional annual inspection, testing and maintenance.

Local rules may differ. What's the difference between a "fire alarm system" and interconnected smoke alarms? A fire alarm system is defined in the fire-safety standards as having a central control panel FACP with inputs from heat or smoke sensors and it sends out alarm signals to audible, visual and communication devices, when triggered.

It may also release self-closing fire doors, send elevators to safe locations, shut down or start various ventilation units, and other things to increase safety during an alarm. An FACP has its own power supply and backup and often supplies power to sensors through direct or loop wiring. Interconnected smoke alarms, on the other hand, have individual units, each containing sensors and local alarms of their own, but they are connected to activate other units.

For interconnected alarms, will one unit chirp if an other unit is bad or battery low? Generally, no. Each individual unit has its own chirp and won't activate any other low-battery or unit failure signals in connected units.

The alarm conditions are what get shared by the interconnections. It's possible that some interconnected units share other information, such as how many units are working and signal other "trouble" conditions to each other.
