The SS-2012 (System Sensor Model 2012H) Photo Optical Smoke Detector has a sleek low-profile design for applications where low voltage is required.

This detector is non latching and offers an 85db sounder output to alert occupants. An external push button is located on the front to provide the ability to test the alarm function of the detector.  Up to 12 units can be interconnected so if one detector alarms they will all sound off.  A LED indicator flashes once every 30 sec to indicate detector is in standby and rapidly flashes every 0.5 sec in alarm.  Relay has a built in 8 second delay to reduce false alarms.
