S Detector
Junction Box
The stainless steel, corrosion resistant junction box allows you to install the detector at a
mounting site that is remote from a controller, and it protects the detector wiring
connections. Two conduit hubs allow you to mount the detector to the junction box and
connect the wiring from the detector to a controller. An O-ring seals the interface between
the junction box cover and the junction box base.
The terminal block within the junction box facilitates the wiring process. A cover on the
front of the junction box allows access to the interior of the junction box. A locking set
screw on the junction box cover allows you to secure the junction box cover and prevent it
from being removed.
Installation
This section describes procedures to mount the H

environment and wire the detector to a controller.
Mounting the H
2
S Detector
1.
Select a mounting site that is representative of the monitoring environment. Consider
the following when you select the mounting site.
•
Select a site where the detector is not likely to be bumped or disturbed. Make sure
there is sufficient room to perform start-up, maintenance, and calibration
procedures.
•
Select a site where the target gas is likely to be found first.
NOTE:
If your application does not require a specific mounting site, mount the detector
at approximately breathing level.
