Sensaphone Smoke Detector with Battery backup - smoke sensor

The Smoke Detection Sensor can be used with all Sensaphone models to monitor for the presence of smoke in commercial or residential applications. When the sensor detects smoke, it will trigger the Sensaphone to go into alarm and also sound an audible horn. The sensor requires hard-wired 120VAC 60Hz power for operation. It is connected to the Sensaphone via accessory wire (not included).
