- Test manual pull stations through a full range of motion and verify the proper signal was received at the alarm panel.
- Test heat detectors with a heat gun and verify proper alarm activation at the fire alarm control panel.
- Test and inspect all audible and visual devices to ensure that they are unobstructed, proper lights activate and the sound level is above ambient noise levels.
- Random check of circuit supervision to ensure fire alarm panel detects an open circuit.
- Load test stand-by batteries and check auxiliary functions such as door release and damper release.
- Test battery charger.

Why Professional Fire Alarm System Inspections are Important

Fire alarm systems consist of much more than smoke detectors on the walls or the fire annunciator panel in the front of your building. The whole fire alarm system is much deeper, with many elements kept out of sight. As a result, you might not be able to check every element of your fire alarm system every day. During a routine annual fire alarm system inspection, the various components of your fire alarm system are exercised and tested to make sure they’re all in good working order. This includes all manual pull stations, alert/alarm methods (strobes and horns), smoke and heat detectors, duct detectors, annunciator panels, the main alarm panel and any communications sub-panels and battery backup supplies.
Having a working fire alarm system installed in your building saves lives. According to the NFPA, fire alarms increase the chance of survival by as much as 50%!
