The Fire Alarm Panel supports 4 zones, each of which can be used for Fire / Smoke / Temperature or Intruder detection (security). The selection of fire or intruder detection is done internally, by using a DIP switch. Each zone can support up to 8 sensors. Two potential free change-over contacts, one each for fire and security, are provided to extend the alarm to remote locations.

When used for fire detection, any fire sensor in the zone getting activated will trigger the alarm condition. Corresponding LED on the Panel will glow and internal buzzer will start making sounds enabling the external Hooter to sound and the potential free contact changes state. The fire shall be acknowledged by using the key switch on the front of the Fire Alarm Panel. On acknowledging, the hooter will go off but the buzzer will remain ON, reminding of the fault. Once the fault has been attended to (fire put off) the alarm shall be reset clearing the alarm. Trying to reset the alarm without attending to the fault will cause the hooter to go ON again.
