DSC AMB-500 SF 05/03 It is an electronic detectionEffective motion detection is dependent on a sensors ability to identify intruders and provide true false alarm resistance. The addressable ceiling mount motion detector (AMB 500) achieves superior detection through a special fresnel lens made for 360 detection and a quad element PIR sensor optimized for uniform detection all around its field of view. To ensure trouble free operation for many years, special attention is given to false alarm immunity
