What is the minimum water pressure required for a sprinkler system's waterflow alarm to function properly?

The minimum water pressure required for a sprinkler system's waterflow alarm to function properly is 30 psi. This level of pressure ensures that the waterflow alarm can accurately detect the flow of water through the sprinkler system. If the pressure is too low, it may not activate the alarm, potentially compromising the system's ability to provide an alert in the event of a fire or other emergency.

In most sprinkler system designs, a sufficient pressure is crucial for the reliable operation of alarms and other components; thus, the established standard is set at 30 psi. This threshold supports the effective performance of the system by ensuring adequate water flow at the sprinklers and allowing alarms to signal any system activation correctly. Understanding these requirements is key in adhering to safety standards and ensuring the fire protection system is functioning as designed.
