M6183 PIR Sensor -

by a 9-Volt battery or AC power, the PIR Sensor senses temperature change when a person moves into the operating range of the infrared beam, activating the Posey Alarm. Since the PIR Sensor senses temperature change rather than motion, the chance of a false alarm is minimized. The PIR Sensor is compatible with any sensor activated Posey Alarm.
