PIR detectors should have a normally closed clean contact output which opens
when movement is detected.
PIR detectors can be powered from the Advent XT2
system network using a 24V-12V Regulator Board
(Tynetec P/No. A00557) fitted locally in the intercom.
Alternatively, an auxiliary 12V DC battery backed
PSU can be used.
Multiple PIR detectors can be connected to the intercom in a normally closed loop.
