With a high level of adaptability, the Elite PIR Detector offers a wide variety of modes of operation, meaning it can offer various permutations of normally open or closed arrangements for the two volt-free relays, plus a selection of timing and functional options for the changeover contacts. Other programmable parameters include the duration of timed changeover, a pulse count feature and a choice of detection ranges from 10 to 35 metres.
