Active Infrared Fence Sonsors: 2 /3 /4 /6 /8 /10 infrared beams optional, Alarm is triggered when any of adjacent double beams(bundles) are shutoff, and sending the sign to the control panel.
This Perimeter Intrusion Detection Systems is a multi beams photoelectric sensor designed for a wide variety of outdoor and indoor residential, commercial and industrial applications. It provides ideal cost-effective solutions for medium-range applications such as perimeter protection of buildings, two sides of the yard door, window, fences, warehouses, factories, parking lots, gardens, walls etc, especially inner balcony to substitute metal structure.
Operating principle as bellows: Several invisible defense bundles from the remitters forms a complete protection network. Alarm is triggered to send the sign to the control panel when any of adjacent double beams are shutoff at one time, this design provides the redundancy needed to prevent false alarms from objects (flying birds, insects, falling leaves, etc.) that may intersect one of the IR beams. The alarm output is activated only when 2 beams are interrupted. So it can protect the objective area from the intruder, and detecting intrusion when an intruder disturbs the detection field effectively.
It is used with cotrol panel (Security Alarm System). Output type of signal: wired, wireless, wired&wireless is also optional. |
