How frequently should gauges connected to air pressure supervision be inspected at a constantly attended location?

Gauges connected to air pressure supervision play a critical role in ensuring the proper functioning of water-based fire protection systems, particularly in systems that rely on air pressure, such as dry pipe and pre-action sprinkler systems. The frequency of inspection is defined to ensure that any changes in pressure are detected promptly, which is vital for system reliability and safety.

In constantly attended locations, it is required to inspect these gauges on a monthly basis. This frequency helps to ensure that any discrepancies or abnormalities in pressure are addressed quickly, minimizing the risk of system failure. Regular monthly inspections also align with general maintenance practices that prioritize proactive monitoring of fire protection systems, as a failure to maintain proper pressure levels can lead to ineffective fire suppression during an emergency.

While other options suggest less frequent inspections, such as quarterly or annually, these intervals may not provide sufficient oversight in environments where immediate response to changes in system status is crucial. By adhering to the monthly inspection standard, facilities can better ensure that their fire protection systems remain operable and effective in an emergency situation.
