External, infrared and microwave motion detector by OPTEX with active ANTIMASKING technology and DAY/NIGHT function. It creates a 180° detection angle through 2 double pyroelectric elements (corresponding to two VXS devices installed next to each other). It has separate distance and sensitivity adjustment for each 90° area, two separate outputs (NO/NC) ALARM (L) and ALARM (R) in case the differentiation of the sides in 2 separate zones is selected.Mounting height 0.8-1.2m (LOW MOUNT) with selectable detection range from 2.5m to 12m. Alternatively, it can be placed at a height of 2m (HIGH MOUNT) with a predetermined detection range of 9m. Detection speed: 0.3~2m/sec , 14 coverage zones. Sensitivity: 2ºC@0.6m/sec. It has distance adjustment levels, SMDA logic to avoid false alarms, automatic temperature control circuit, NO/NC, Operating voltage: 9.5-18VDC, Consumption: 24mA, equipped with Wall Tamper, IP 55, Operating temperature: -20ºC +45ºC.Dimensions: 81.5 x 201.5 x 86.3mm
