Maintenance of fire extinguishing systems that contain constant or fire-activated systems shall be performed every

• A. 6 months
• B. 12 months
• C. 3 months
• D. 1 month

Answer: (A)

Automatic or continuously activated fire-extinguishing systems need regular checks to stay ready, because faults can develop silently in valves, actuators, wiring, or the delivery pipes. The typical maintenance interval for these systems is semi-annual—about every six months. This schedule allows a thorough verification of the release mechanism, detection and alarm interfaces, control circuitry, and the agent charge or pressure, plus a check for any leaks or corrosion. Doing a semi-annual service strikes a practical balance: it catches developing problems before a fire, without the excessive cost or downtime of more frequent servicing. Monthly visual checks are common for portable extinguishers, while yearly service alone can miss evolving issues in fixed, automatic systems.
