According to NFPA 72, Fire Alarm Initiating devices are defined as devices used to manually or automatically signal a fire alarm system to initiate responses from equipment and people. These devices connect to the alarm system’s control panel and are under the control panel’s surveillance. When triggered, the control panel identifies the location or zone and then goes into the alarm stage, sounding alerts throughout the building and sending commands to emergency responders. Fire alarm initiating devices play an integral role in the overall efficacy of a fire alarm system. These devices act as the fire alarm system’s trigger, and without proper functionality, the control panel would be unable to identify the activation and the entire system would fail.
