Two-beam infrared barrier with range up to 100 meters. It has an LED that indicates beam alignment, an anti-tamper switch and automatic gain control in any environmental condition (rain, fog, snow, etc.). Response time adjustable from 0.05 to 0.7 seconds. The use of a double beam considerably reduces the problem of false alarms; in fact, the device generates the alarm signal only if the two beams are interrupted at the same time. The set consists of a transmitter, a receiver and mounting accessories.
