SECO-LARM’s ENFORCER Long-range barrier sensors are available in four lengths (26, 43, 61 and 79 in.) with a corresponding number of beam pairs (2, 4, 6, 8). They provide broad perimeter detection with an outdoor range of up to 190 ft. and an indoor range of up to 380 ft. They are programmable, with four frequencies to reduce interference and specific response times. Swiveling end-caps allow users to adjust the angle of the sensors, and a built-in heater automatically turns on and off depending on the outside temperature.
