High bay PIR detectors

May 2012 Sensors & Transducers

CP Electronics has two high bay PIR detectors which are specifically designed for the detection of movement in high bay lighting applications such as warehouses and factories. Both the EBDSPIR-HB-PRM and the EBDSPIR-HB-DD can be used in either presence detection or absence detection mode, with incandescent, fluorescent and compact fluorescent light sources, to provide automatic control of lighting loads with optional manual control.

The versatile EBDSPIR-HB-DD detector can also be used in conjunction with DSI or DALI dimming ballasts over one or two channels to maintain illuminance at preset lux levels, dimming the lighting in proportion to the levels of natural daylight entering the space. The switching channel of the detector can either be used to isolate the supply to the dimming ballasts (saving on the standby current of the ballasts) or to switch a separate channel of standard, non-dimming luminaires.

Two input terminals can be used to manually override the dimming levels and the lights on or off. The flexibility of having two channels and two switch inputs allows dimming an outside row of luminaires whilst internal fittings are switched; absence detection for two separate channels; and a maintained illuminance system with manual up/down controls.

For ease of commissioning and reconfiguration, both units can be supplied with a DD-LCDHS-LR programming handset, giving complete flexibility over many of the operating parameters. Without the handset, manual adjustments can be made to the sensitivity, lux and time settings using the controls on the rear of the detector head.
