ABSTRACT:
A smoke detector indicator for a fire alarm system having an ON-OFF switch indicator system that permits the audio alarm to be turned off for false alarm situations, but has a visual indication that the system is not in operation. In a system including a circuit connecting a smoke detector, battery and an audio alarm, all in a single enclosure, the improvement comprises a switch in the circuit to open the circuit and prevent the alarm from sounding, and a visual indicator associated with the switch, visually apparent when the circuit is open, and not visually apparent when the circuit is closed.
