How quickly should a water flow device initiate an alarm?

A water flow device should initiate an alarm within 90 seconds in accordance with established fire alarm system standards. This time frame ensures a timely response to potential water flow conditions that could indicate a fire event or system malfunction. The purpose of a prompt alarm activation is to ensure that first responders are alerted quickly, allowing them to take appropriate actions to mitigate the situation.

Responding within 90 seconds is crucial to maintaining safety within buildings and is aligned with the expectations of rapid emergency response protocols. This guideline helps in minimizing damage and ensuring tenant and firefighter safety, as delays in alarm activation could lead to significant risk.- Thus, the specification of 90 seconds as the standard reinforces the importance of immediacy in alerting fire services when water is detected flowing in a system, indicating an emergency scenario.
