A sprinkler waterflow device must initiate an alarm signal at the control unit within how many seconds of water flow?

When waterflow is detected in a sprinkler system, the alarm must be signaled to the control unit within ninety seconds. This timing strikes a balance between quick notification and avoiding nuisance alarms. It gives enough time for hydraulic movement and detector processing, while still ensuring occupants and responders are alerted promptly in a real fire. Choosing a much shorter limit could increase false alarms from normal fluctuations or minor leaks, while longer limits would delay critical notification during an actual fire.
