Wiring Motion Detectors
Motion detectors are basically switches with electronics built-in to make the connection.
Wiring is similar to a normal door switch input, however, the motion sensor requires an
external power supply of 12 VDC or 24 VDC (UL listed under APHV). The maximum
length wire you may use is 500 ft of #18 gauge wire (152 m of 1.0 mm
2
wire) or 200 ft of
#22 gauge wire (60 m of 0.35 mm
2
wire).
