Camden's CM-RQE70A PIR 'REQUEST TO EXIT' Detectors provide the latest word in design, with a complete list of "high performance" features, including secondary activation device input, door monitoring, 2-relay outputs, and tamper alarm. Many new programming, installation, and set-up features that have never previously been available. Camden started by making the CM-RQE70A smaller, so it can easily fit on door frames, and then made installing the detector faster and easier. CM-RQE70A Comes with 4 factory default operating modes that can be selected with simple push buttons on the circuit board.
