Seco-Larm E-9643-4B190Q Long-Range Barrier Sensor, Four Pairs of Beams

ENFORCER Long-Range Barrier Sensors are ideal for protecting indoor or outdoor areas separated by long distances. They feature reliable photobeam technology with a choice of four programmable beam frequencies that provide superior perimeter protection by eliminating crosstalk and interference when multiple units are used. False alarms caused by animals, falling leaves, poor weather, or other sources are minimized by programming the alarm output  trigger operation.

ENFORCER Long-Range Barrier Sensors work in even the most extreme conditions. A built-in heater automatically turns on and off depending on the outside temperature. An environmental control system senses a slow degradation in beam strength when weather conditions worsen to help prevent  false alarms.

Installation and alignment is quick and easy with the ENFORCER Long-Range Barrier Sensors. They come with swiveling heads that allow them to be mounted along the same wall or on opposite walls, as well as provide for easy alignment of the beams between the transmitter  and receiver.
