Combustilbe Gas Transmitter • 4 Pioneer Operator’s Manual (PRELIMINARY)

Junction Box

Use the junction box to install the combustible gas transmitter at a mounting site that is

remote from the Pioneer. The junction box also protects the ampliﬁer and wiring

connections made to the ampliﬁer. Use the two 3/4 in. conduit hubs to mount the detector

to the junction box (bottom hub) and connect wiring from the ampliﬁer to the Pioneer

(top hub).

NOTE:

The combustible gas detector and ampliﬁer are factory-mounted to the

junction box.

Use the junction box’s two mounting holes to mount the combustible gas transmitter to a

vertical surface at the monitoring site. Use the cover on the front of the junction box to

access the interior of the junction box.
