4.2.4 General
Install conduit as required by local code or construction specifications. Provide for splice boxes where multiple modules will
be wired to a single run. Pull conductors of the correct gauge wire from the controller to each splice box and from the
respective splice box to each planned module location. See for proper wire termination in the splice box. Twisted wire
secured with wire nuts is not an acceptable splice.
NOTE: The drain wire of shielded cable must NOT be used as one of the conductors. Installation and wiring
must be in accordance with the National Electrical Code. Temperature rating of cable wire must be at least
75°C. If cable runs through higher temperature environments, it must be specified for that environment.

Enclosure Installation
To protect the transmitter and sensor assembly they should be removed from the enclosure and preserved until final
installation and wiring termination.

Prior to installation and wiring complete the following steps.
1. Remove the transmitter from the module housing by:
a. Unscrew the two captive panel screws on the faceplate.
b. Lift the transmitter out of the enclosure.
c. Unplug the sensor cable from transmitter connector P2.
d. Remove the sensor assembly from the enclosure hub.
2. Install the module enclosure onto the end of the supply conduit and/or bolt into position as required.
3. For hazardous locations an Explosion poof seal fitting must be installed within 18" of the detector.
NOTE: When enclosure earth grounding is required for the installation a grounding lug is located in the base of
the enclosure. Install the earth ground under the green ground screw.
