This is the CP Electronics PDS-PRM, a No Neutral Wall Mounted PIR Presence Detector (occupancy sensor) for back box wall mounting (back box to be purchased separately), ideal for occupancy detection.
The modern CP Electronics PDS-PRM presence detector switches are designed to provide automatic control of lighting, heating or ventilation loads. They detect movement using a PIR sensor which subsequently switch the load on or OFF; a photocell is included to prevent lights from turning on during daytime to save on electricity. If an area is no longer occupied the load will switch off after an adjustable time out period.
An internal light sensor provides additional energy, saving in lighting applications. When an area is occupied, the lighting is only turned on when the level of natural light goes below a preset level. A selectable security mode switches the lights on for a period of 2 hours when it gets dark, regardless of occupancy, to give the impression of a building being occupied in order to ward off potential intruders.
Since this sensor doesn't require a neutral connection, it can quickly replace an existing light switch with a more energy efficient option. It works with a wide variety of load types including low energy CFL and LED lamps.
Features: presence detection and lux level sensing - auto on, auto off. LED compatible. 2 wire (neutral) Adjustable time delay and lux settings via pots.
