The addressable passive infrared detector (AMB-300) employs a large, multi-beam lens design, patented Multi-Level Signal Processing (MLSP) and temperature compensation to ensure human targets are identified. To ensure trouble-free operation for many years, special attention is given to false alarm immunity against RF, static and electrical transients. The detector uses a two-wire connection to the control panel that helps to reduce installation time and cost. The low current draw of the detector helps maximize the number of devices that can be attached to an addressable loop.
