Valve enclosures for pre action/deluge valves equipped with low temp alarms are to be inspected how often?

• A. Monthly
• B. Daily
• C. Annually
• D. Weekly

Answer: (D)

Weekly inspections are required for valve enclosures on pre-action and deluge systems that have low-temp alarms because these alarms and their enclosures must be kept ready to detect freezing and alert personnel. Space around these valves is often not conditioned, so door seals, tamper switches, wiring, and the alarm circuit can degrade or become obstructed over time. Regular weekly checks help verify the enclosure is accessible, the alarm is present and functioning, and the valve status and wiring are intact, reducing the risk of a undetected fault that could compromise system operation in cold conditions. Daily checks would be unnecessarily frequent for these components, monthly could miss developing issues, and annually would risk undetected faults accumulating over a long period.
