In a fire alarm system, what is the action described by the term 'supervision' in fire alarm systems?

• A. Monitoring circuits for faults
• B. Activating alarms only
• C. Disabling alarms during maintenance
• D. Centralizing power supply

Answer: (A)

Supervision means continuously monitoring the status and integrity of the fire alarm system’s circuits and devices to uncover faults. This includes checking that loops are intact, detectors and pull stations have power and communicate correctly, and that any protective devices like tamper switches or power supplies are functioning. When a fault is detected—such as an open or shorted circuit, loss of power to a device, or a tamper condition—the panel signals a trouble condition so technicians can address it. This is different from simply activating alarms in response to a sensed condition; supervision is about ensuring the system itself remains capable of reporting alarms by keeping its wiring and components under watch. It’s not about disabling alarms during maintenance or about how power is arranged, but about detecting faults in the monitoring paths so issues don’t go unnoticed.
