Digital volumetric detector with dual “infrared/microwave” technology with active anti-masking and the exclusive ACT technology. 360º coverage x 13 m Ø at 4 m, 110º opening. The ACT (Anti-Camouflage) technology switches to microwave mode to avoid attempts to camouflage the PIR channel or its ineffectiveness at high temperatures. Anti-masking of the microwave channel and the PIR channel. Detects lens clogging, spray, dirt or lens aging. 3 LEDs for masking, trouble and test indication. Independent anti-masking relay. X-band microwave technology (10.525 GHz). Adjustable microwave. Green Line technology that allows the microwave channel to be disconnected in day mode. Selectable integrated end-of-line resistors. Low profile design. Double tamper. Exceptional immunity to electromagnetic and fluorescent interference. Power supply from 9 to 16 Vdc. Max. consumption: 39 mA. Dimensions: Ø 135 x 27 mm. EN50131 Grade 3 certified.
