Securitron® XMS Exit Motion Sensor, 12/24 VDC, Surface Mount, Plastic, Clear

The XMS passive infrared request-to exit device is a motion detector specifically designed to reliably release magnetic locks. A person approaching the door is "seen" by the motion detector just before reaching the door. Versatile mounting options and an easily adjustable infrared beam pattern provide optimal coverage of the egress area for smooth, hands-free lock release and exit.
