What is the term for monitoring detector and notification appliance circuits for faults?

• A. Supervision
• B. Isolation
• C. Segmentation
• D. Alarm verification

Answer: (A)

Supervision is the practice of monitoring detector and notification appliance circuits for faults. In a fire alarm system, these circuits are supervised so the control panel can detect problems like open or shorted wiring, a disconnected device, or a failing power supply. When a fault is detected, a trouble condition is generated, signaling maintenance to fix the issue and ensuring the system will still operate correctly in an emergency. This differs from isolation, which focuses on removing a faulty device from the circuit to keep the rest of the system running; segmentation (zoning) divides the system to localize events; and alarm verification aims to confirm an initiating signal before sounding the alarm to reduce false alarms.
