MWS1A-PRM is a low profile back box mounted wall Microwave Presence Detector. MWS1A series of contemporary styled microwave provide automatic control of lighting, heating or ventilation loads, via highly sensitive microwave technology. Low power microwave signals are emitted and then measure the reflections as the signals bounce of moving objects. The MWS1A is optimised for wall mounting applications where long distance detection is required. Presence detection. Detection range of up to 30 metres when wall mounted. Suitable for heating and ventilation applications. Fixing screw cap covers smooth plate finish. The MWS1A is a highly sensitive motion detector by emitting very low-powered microwaves – similar to how radar guns operate. A wall-mounted detector designed to detect motion over large distances. The new MWS1A-PRM presence detector range builds on their already tried and trusted detection technology to give you even more functionality for your lighting control needs.
