During cold weather, how often shall low temperature alarms be tested?

• A. Daily
• B. Weekly
• C. Bi-weekly
• D. Monthly

Answer: (B)

Low temperature alarms are there to catch freezing conditions that can damage water-filled pipes and sprinkler components. In cold weather the chance of sensor drift, battery drain, wiring faults, or other malfunctions increases, and a fault can go unnoticed for days. Testing these alarms weekly during cold snaps ensures that the audible/visual indications, supervisory circuits, and any remote monitoring are all working, so warnings reach building staff in time to prevent freeze-related damage. Daily testing is usually unnecessary and burdensome, while bi-weekly or monthly testing could allow a fault to go undetected for too long when conditions are most risky. Weekly testing strikes a practical balance, keeping the system reliable through the worst weather. Follow the site’s testing procedure and document results each time.
