After replacing one horn/strobe, what must be done before leaving the premises?

• A. Notify the property owner.
• B. Visually inspect the area.
• C. Functionally test the horn/strobe you replaced.
• D. Update the service log.

Answer: (C)

After replacing a horn/strobe, you must perform a functional test of that device before leaving. This confirms the horn will actually sound, the strobe will flash, and the device properly communicates with the fire alarm control panel. A visual check only confirms appearance and basic wiring but doesn’t prove the device will operate correctly when an alarm is triggered. While updating the service log is important for records, and informing the property owner may be part of good service practice, the essential step to ensure life-safety signaling works is a functional test of the replaced horn/strobe.
