Exit sensor.

A new request-to-exit sensor from GE Security of Bradenton, Florida, combines Doppler Range Controlled Radar motion sensing and Fresnel lens passive infrared (PIR) technologies. The Dual Technology RCR-REX requires both physical motion and heat to trigger the device, so it resists common attempts to defeat sensors that use only PIR. Because the radar can be adjusted with its threshold above the floor, it will not respond to illicit strategies such as forcing a warm liquid or a coat hanger under the door. When properly activated, the sensor triggers the door latch quickly and limits the number of people allowed in or out and the length of time the door can be opened. A built-in sounder signals that the door is not sealed or if the door is unlocked for too long. 604
