Seco-Larm Enforcer Curtain Sensors, In/Outdoor, 4 Beams, 22.5 In., White (E-9622-4W25) [並行輸入品]

商品説明

Suitable for indoor and outdoor perimeter security, the SECO-LARM E-9644-4W25 ENFORCER Curtain IR Motion Sensor can monitor entire windows, doorways and/or skylights. There are four (4) photoelectric beams that can be used over a span of up to 50 feet indoors or 25 feet outdoors. The trigger is programmable for recognizing the simultaneous breaking of any single or two adjacent beams. The design features rugged aluminum construction, and an anti-tamper circuit for triggering an alarm if power is cut or the end cap is removed. These infrared photobeam curtain/barrier sensors are perfect for installation in windows, doorways, skylights, fence tops or any place where space is limited. No synchronizing wires are required and the LED alignment indicator makes installation easy. L-brackets and mounting hardware are included. There is a normally open (N.O) and a normally closed (N.C.) relay output that can be used to communicate with your security system. These sensors are ideal for monitoring any possible entry point to your property, and because they are weatherproof, they are the ideal choice for almost any indoor or outdoor application.
