Seco-Larm Enforcer Long Range Barrier Sensor, 190'
[WRITTEN BY KAYLA HALL] The Seco-Larm Enforcer Long Range Barrier Sensor, Indoor/Outdoor, 190ft provides an easy way to implement long-range perimeter security for any area on your property. This sensor includes a transmitter and receiver that will trigger when there's either a simultaneous breaking of beams or after a single pair of beams is broken for at least 2 seconds. Using reliable photobeam technology, this sensor provides four programmable beam frequencies to eliminate crosstalk and interference when multiple units are used. It also allows you to program the alarm output trigger operation to reduce false alarms caused by falling leaves, animals, bad weather and other sources.
