Presence detector with dimming
March 2012
Sensors & Transducers
CP Electronics’ new passive infrared (PIR) presence detector provides automatic control of lighting loads with optional manual control. The EBDHS-DD is a high sensitivity detector suitable for high bay applications, such as warehouses and factories where high detection sensitivity is needed. It is designed for ceiling mounting and all functionality is fully programmable using an IR handset.
Output channel 1 comprises a mains voltage relay capable of simple on/off switching, while channel 2 provides dimmable control of either DALI or DSI type ballasts. 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, or to implement a luminance daylight harvesting system.
The flexibility of having two channels and two switch inputs allows the following example scenarios: dim an outside row of luminaires whilst internal fittings are switched; provide absence detection for two separate channels; maintain an illuminance system with manual up/down controls.
The PIR sensor detects movement within the unit’s detection range, allowing load control in response to changes in occupancy while a light level sensor measures total light level in the detection area.
