Part of the WXI series, a range of 12m 180 degree outdoor volumetric PIRs, the WXI-RAM is the wireless, anti-masking 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. The WXI series features 180 degree 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. The battery-operated WXI-RAM can be easily added on most wireless alarm systems and provide the benefit of protecting quickly and efficiently the boundary of the premises and of any outer buildings. Most wireles transmitters will fit inside the sensor back box and can feed power to the WXI-RAM. Additionally the anti-masking will detect if any objects had covered the lens and send a trouble signal to the alarm panel.
