The battery-operated Optex CX-702RS Wireless Indoor Passive Infrared Detector with Dual Lens is designed to give stable long-range detection performance in a variety of internal commercial and industrial applications. The CX-702RS comes with a back box and works with most manufacturer's wireless transmitters. Because it is battery-powered, wiring is not required and allows for an easy install. With patented Multi-Focus technology, sensitivity is maintained through the entire coverage area, even in high temperature areas or in applications with low temperature contrast. Combined with double conductive shielding and temperature compensation, a high level of false alarm protection is guaranteed. In addition, the detector features the ability to choose between a 70 x 70' pattern and a 150 x 8' with a simple flip of the lens.
