c) Terminate 2 conductor field wiring to the sensor terminal board observing correct polarity in accor-

5.5 Remote Mounting Applications
Some sensor mounting applications require that the gas sensor head be remotely mounted away from the
sensor transmitter. This is usually true in instances where the gas sensor head must be mounted in a loca-
tion that is difficult to access. Such a location creates problems for maintenance and calibration activities.
Detcon provides the DM-434B sensor in a remote-mount configuration in which the sensor (Model DM-
434-RS) and the transmitter (Model DM-434-RT) are provided in their own condulet housing and are inter-
faced together with a four conductor cable. Reference figure 3A below for wiring diagram.
