Presence detection avoids wasteful lighting
Published:  August 2007

Small and compact, this presence detector from CP Electronics avoids the wasteful use of light – and also incorporates a photocell.

A ceiling-mounted presence detector that can be surface- or flush-mounted onto a British Standard switch box has been introduced by CP Electronics. The SPIR-F/C detector monitors the zone and switches on automatically when occupancy is detected and off a preset time after the area has been vacated. The time delay can be adjusted from 10 s to 30 min. If there is sufficient natural light, a built-in photocell keeps the lighting off.

All CP presence detectors are designed to reduce energy wasted by lighting being left on unnecessarily. Savings of 40% can easily be achieved, depending on occupancy. The SPIR-F/C can also be used to control heating and ventilation loads.
