Common Misconceptions in Life Safety: 'My Alarm Company Does That'

Written by LSS | Nov 20, 2014 3:00:00 PM

Who tests the fire and smoke dampers in your facility? This is perhaps one of the most common misconceptions that we run across in the field of life safety and we wanted to take just a moment to help try and clear up any confusion you might have about who tests what. Many people think that their alarm company in fact tests the dampers during their routine annual inspection of the alarm.  This is not the case, as illustrated in the steps below.

 

Combination Fire and Smoke Dampers

STEP 1 - The relay and alarm panel is test by the alarm company making sure the alarm panel is "speaking" to the actuator/motor on the damper.

STEP 2 - The smoke detector or relay from the area smoke detector system is tested by the alarm company, but they do not test the damper.

Actuator/motor is tested by a damper expert making sure the damper operated and is in compliance with NFPA 105.

 

Fire Damper Inspection

Fire dampers are operated manually and are not connected to an alarm panell, therefore the alarm company would not test them.  In an emergency, the fire damper closes when the fusible link melt at a specified rating per link.

Fire dampers are tested and inspected by a damper expert who manually releases the link ensuring the damper operated per NFPA 80.

 

We have created this cheat sheet for you to help you better understand the difference between the alarm test and the code mandated fire and smoke damper inspection.

 

Task Alarm Company

Damper Expert such as LSS

Test relay is communicating with smoke damper from Fire Panel YES (Per NFPA 72) no
Develop report showing a listing of the  location of all dampers with identifier, a pass/fail result complete with a detailed explanation of failed dampers if applicable no YES (Per NFPA 80 and 105)
Digital photographs of each damper before and after performance of the inspection services (showing each damper opened and where operable, closed) no YES (Per NFPA 80 and 105)
Operate (i.e. actuate) all dampers no YES (Per NFPA 80 and 105)
Remove and reset all fusible links on fire dampers to   verify closure no YES (Per NFPA 80 and 105)
Replace fusible links that are compromised no YES (Per NFPA 80 and 105)
As necessary, lubricate all moving parts on each damper no YES (Per NFPA 80 and 105)
Clear each damper of any debris that would impede   normal operation no YES (Per NFPA 80 and 105)
Coordinate with local fire department to place customer's fire alarm system in test mode to conduct      inspection of smoke and /or combination dampers no YES (Per NFPA 80 and 105)
Manually activate actuators on electric & pneumatic smoke and or combination dampers to verify operation no YES (Per NFPA 80 and 105)
If no access to existing damper, properly sized access doors will be installed by contractor to facilitate          inspection no YES (Per NFPA 80 and 105)
Apply identification stickers on ceilings or other location to assist in locating dampers following inspection no YES (Per NFPA 80 and 105)
Provide customer with pricing to repair dampers that have failed an inspection no YES (Per NFPA 80 and 105)
Provide customer with repairs of failed dampers no YES (Per NFPA 80 and 105)
Mark locations of dampers on customer drawings if    applicable no YES (Per NFPA 80 and 105)
If damper inaccessible, location will still be mapped on prints and included in report no YES (Per NFPA 80 and 105)

 

Keep in mind that dampers fail frequently. Periodic inspection is the only way to confirm full functionality. Roughly 10% of dampers fail in facilities with a history of performing routine damper inspections.  A staggering 35% of dampers fail in those facilities not performing periodic inspections. Where does your facility fall?
