MWS6 PRM LV Product Guide lectronics intelligent energy control Ceiling Microwave presence absence detector 12 24V AC DC Overview E bet The MWS6 PRM LV Microwave presence detector provides automatic control of low voltage loads including lighting and BMS systems with optional manual control The MWS6 PRM detects movement using a highly sensitive microwave detector This works by emitting low power microwave signals and measuring the reflections as the signals bounce off moving objects Functioning as a presence detector the unit can turn lights on when a room is occupied and off when the room is empty Optional settings allow lights to be turned off in response to ambient daylight All functionality is fully programmable using an IR handset MWS6 PRM LV Ceiling Microwave presence absence detector 12 24V AC DC MWS6 PRM LV GOLD Ceiling Microwave presence absence detector 12 24V AC DC for low current MWS6 PRM LV OC Ceiling Microwave presence absence detector 12 24V AC DC and open collector output Front features Mounting Bezel Sy Sensor Lens which covers Microwave Sensor IR Receiver Light Level Sensor Status LEDs Back features Retaining Spring Switch Input Connector Power Input amp Output Connector Retaining Spring Microwave Sensor Detects movement within the unit s detection range allowing load control in response to changes in occupancy IR Receiver Receives con2.
