What is the role of a fire alarm control panel (FACP) and what basic checks should a custodian engineer perform?

• A. The FACP controls lighting in the facility; perform lamp checks and ballast replacements.
• B. The FACP handles power distribution to non-fire systems; inspect circuits.
• C. The FACP monitors detectors and initiates alarms; perform power checks, detector tests, annunciator checks, and periodic alarm tests.
• D. The FACP is a manual switchboard; test manual call points.

Answer: (C)

The fire alarm control panel is the central brain of a fire alarm system. It continuously monitors detectors and manual calling points, and when a condition is detected, it initiates alarms to warn occupants and, if connected, signals to a monitoring service or building management. This role is why the best checks focus on ensuring the panel and the system it controls are healthy and responsive.

Basic checks you would perform include: verifying the panel has proper power, including the status of backup batteries, so you don’t lose the system during a power failure; testing detectors to confirm they respond as expected to a recognized test signal; checking annunciators on the panel and any remote indicators to ensure status indications are accurate and up to date; and conducting periodic alarm tests to confirm that the entire sequence—from detector activation to audible/visual alarms and notification appliances—operates correctly. These checks together verify that the FACP can reliably detect a fire condition, raise the alarm, and drive the signaling devices as designed.

The other described roles aren’t aligned with what the FACP does: it isn’t responsible for general lighting control or power distribution to non-fire systems, and while manual call points are part of the system, the FACP’s primary role is to monitor and coordinate the fire alarm network rather than act as a simple manual switchboard.
