4.1
WIRING PROCEDURE
IMPORTANT
Do not apply power until the wiring procedure is
complete and has been verified.
1. Locate the sensor where it will be accessible for
maintenance. Excessive heat or vibration can
result in premature failure of any electronic device
and should be avoided if possible.
2. The junction box should be electrically connected
to earth ground.
3. Figure 8 shows typical wiring for stand alone
operation. Figure 9 shows typical wiring for
PIRVOL with Det-Tronics supplied junction box.
Figure 10 shows the wiring terminals located
inside the junction box. The PIRVOL wiring color
code is:
Red lead
= +24 volts dc
Black lead = – (common)
White lead = 4 to 20 ma signal output
Yellow lead* = Calibration input
Green lead = Chassis ground
* If the calibration wire (yellow lead) is not
being used, do not connect this wire to
ground. Trim excess length and insulate wire
so no shorting can occur.
