Sensor separation/remote mounting of sensor
When it is necessary to mount the sensor remotely (separated from transmitter), by way of junction
box and conduit, it is important that the installer follow the necessary requirements and guidelines
relating to sensor separation and cable selection. See
Figure 2-9
for typical remote mounting of sensor.
Also refer to
2.4
for information on wiring guidelines.
When sensors are being mounted remotely, consult the multi-purpose junction box manual
(
MAN-0081
) for wiring instructions. Always ensure that the transmitter is supplying 10.5 - 32 VDC
across the sensor power terminals (VDC + and COM) of Net Safety junction box (JB-MPD-A/S).
The maximum distance between the sensor and transmitter is limited by the resistance of the
connecting wiring, which is a function of the gauge of the wire being used. For effective
communication, Net Safety limits the separation distance between sensor and transmitter to 2000 feet
(600 meters) using 16 AWG wire. See
Section 9
for information on typical wire gauge and resistance.
