During a yearly fire alarm system test, which tasks are typically performed?

• A. Replacing all devices in the system.
• B. Functional tests of initiating devices, verification of NAC operation, battery load test, programming verification, and wiring integrity checks.
• C. Testing only the battery and nothing else.
• D. Only visual inspection of the enclosure.

Answer: (A)

Annual fire alarm testing focuses on confirming the system operates correctly and remains reliable, not on replacing every component. The tasks you’d typically perform include functional tests of initiating devices to ensure pull stations and detectors trigger the panel properly; verification of the notification appliances circuit (NAC) to confirm horns, strobes, and other devices activate as required; a battery load test to verify the standby power can sustain the system for the required duration and that batteries recharge properly; programming verification to ensure the panel’s settings, addresses, zones, and logic are correct after any work or updates; and wiring integrity checks to look for loose connections, damaged conductors, and proper continuity and impedance.

Replacing all devices during a yearly test isn’t standard practice because it’s disruptive, costly, and unnecessary unless a device is defective or near the end of its life. Visual enclosure inspection alone also doesn’t verify that the system will operate correctly in an alarm.
