OPTEX WXI-ST 180° wired detector

Part of the WXI series, a range of 12m 180° outdoor volumetric PIRs, the WXI-ST is the wired model. With its comprehensive 180° field of view and capabilities to adapt its settings to the environment around your premises, the WXI series will provide an effective intrusion detection sensor for new and existing security systems. The left and right alarm detection areas can be set independently at 2.5m, 3.5m, 6m, 8.5m and 12m.

180 degree and double layer detection Independent left / right detection area
The WXI series features 180° detection coverage enabling with one single sensor to cover a wide area, such as front garden, courtyard or patio area. The double layered detection allows to ignore animals while detecting people. The WXI outdoor motion sensors provide two detection areas, left and right that can be independently set. For instance, the right zone can be set at 3.5m while the left one is set at 8.5m. The sensitivity can be high in one zone and low in the other to match the operational requirements.
