Head & End Sensor Units 2018-04-18T15:32:24+00:00

Head/End Sensors

are passive devices which do not require being connected to a power supply.  The sensors handle laser signals which they convert and transfer.  The Head Sensor receives the laser signal from the Alarm Zone Controller and the End Sensor returns the signal to complete the light loop.  When an intrusion occurs, an interruption in signal will be registered and will trigger an alarm response.
