PDS range saves energy

PDS is a cost effective presence detector range from energy saving controls experts CP Electronics. Featuring a built-in light level sensor, the PDS unit can be set to keep lights off should there be sufficient natural light. An optional override facility allows extra flexibility i.e. lights can be turned on even when there is sufficient natural light, and then automatically turned off when the occupancy has ceased.
Easy to install, the PDS presence detectors have no neutral connection, so they can directly replace an existing light switch mounted on a BS box. Other key features include multi-way switching, time delay between five minutes and one hour and a detection range of up to nine metres.
