Detector Housing Body, Housing Cap, & Cap Gasket
The detector housing body protects the sensing components within the housing. Use the
mounting threads at the top of the housing to screw the H
S detector into a 3/ 4” NPT hub.
2
Use the removable cap near the bottom of the housing to access the sensor for
maintenance or replacement. The cap protects the sensor from damage and includes a
flame arrestor which contains any sparks which may occur within the detector housing. A
cap gasket seals the interface between the housing and cap. A flame arrestor guard is
permanently bonded to the cap.
Two wires extend from the top of the detector housing. Use these wires to connect the H
2
detector to a controller. The housing includes a four-socket pattern. This socket pattern
accepts the sensor’s four pins to secure the sensor within the detector housing. A preamplifier , located between the sockets a nd two int erconnect w ir es , con diti o ns t he se ns or’s
signal before the signal reaches the contro ller.
Rubber Boot and Spacer
A rubber boot and spacer are installed between the detector housing cap and the sensor.
They help ensure that the detector remains plugged into the detector housing body.
Sensor
The sensor is secured within the sensor housing by four pins. Through a series of chemical
and electrical reactions, the sensor produces an electrical output that is proportional to the
detection range of the detector.

Installation
NOTE: Normally, the H2S detector is shipped already installed in one of the bottom
conduit hubs of a controller and factory wired to the controller . If your detector is
already installed in a controller, use this section for reference only.
This section describes procedures to mount the H
S detector in the monitoring
2
environment and wire the detector to a controller.
Mounting the H2S Detector
1. Whether you will mount the detector directly to a controller or to a junction box, 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. Ma ke sur e
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, mo unt the detector
at approximately breathing level.

2. At the monitoring site, mount the detector in one of the following two ways:
• Screw the detector’s 3 /4 ” NPT mounting thread into an empty conduit hub on a
controller.
OR
• Screw the detector’s 3 /4” NPT mounting thread into an appropriately rated
junction box.
CAUTION: Mount the H2S detector with the detector facing down (see Figure 2).
NOTE: If the mounting site requires the detector installation to be explosion proof, you
must install the detector in a junction box with an internal volume less than or
equal to 69 cubic inches and rated explosion proof for Class I, Groups B, C, and
D.
Wiring the H2S Detector to a Controller
WARNING: Always verify that the power source is OFF bef ore you make wiring
connections.
1. Turn off the controller.
2. Turn off or unplug power to the controlle r.
3. If the detector is mounted remotely from a controller using an explosion proof
junction box, proceed to step 4.
If the detector is mounted directly to a controller, connect the detector’s red and black
wires to the appropriate controller detector terminals and skip to the Startup Section.
4. Remove the junction box cover.
W ARNI NG: To maintain the explosion proof classification of the H2S detector/junction
box combination, a conduit seal must be used within 18 inches of the
junction box conduit hub used for wir ing to the controller.
5. Guide a two-conductor, shielded cable or two wires in conduit through an unused
conduit hub of the junction box.
6. Connect the two wires to the detector using an appropriate terminal block.
CAUTION: If using shielded cable, leave the drain wire insulated and disconne cted at the
detector. You will connect the opposite end of the cable’s drain wire at the controller.
7. Secure the junction box cover to the junction box.
8. Route the cable or wires leading from the H
S detector through one of the conduit
2
hubs at the controller housing.
CAUTION: Do not route power and detector wiring through the same conduit hub. The power
cable may disru pt the transmission of the detect or signal to the controller.
