Premium presence/absence detector

September 2011 Sensors & Transducers

The EBDSPIR-PRM ceiling mounted presence detector from CP Electronics is an extension of the range offering additional features not found on the standard detector, including presence and absence detection.

The passive infrared detector can be set for absence detection, presence detection or both, switching the load on or off according to occupancy after a preset time. The time delay is adjustable between 10 s and 99 minutes and, if there is sufficient natural light, a built-in photocell will keep the lighting switched off. It also has the benefit of optional manual override and can be used with incandescent, fluorescent and compact fluorescent light sources.

An integral infrared communication sensor in the unit allows programming via an optional handset, providing complete flexibility over the operating parameters without the need to gain access to the ceiling void. The sensitivity, lux and time settings can also be adjusted manually using the controls on the rear of the sensor head.

Designed to complement the wide range of sensors in CP’s product range, the EBDSPIR-PRM’s detector parameters include sensitivity on/off, power up/on, walk test, switch level on/off and disable detector mode in which the detector acts as a photocell only. The system is simple to install and is ideal for lighting applications within schools, offices, hotels, retail and commercial applications.
