Fire Sprinkler Monitoring & Accessories

NFPA 72 guarantees a reasonable degree of protection for life and property from fire by defining requirements for signal initiation, transmission,

notification and annunciation, as well as the levels of performance and the

reliability of various fire alarm systems.

Initiation of the alarm signal shall occur within 90 seconds of water flow at the alarm-initiating device when flow occurs that is equal to or greater than that from a single sprinkler of the smallest orifice size installed in the system.

Movement of water due to waste, surges, or variable pressure shall not initiate an alarm signal.
