Choose a dry, flat location on a suitable indoor or outdoor wall,
which will not receive spray from sprinklers. Telephone modem Site
Interfaces (IMMS-SI-MOD) must be located within 6 ft. (2 m) of the
telephone jack. Drive self-tapping screws through recessed holes in
plastic cabinet back into solid surface. Ambient operating temperature
must not exceed 120°F (50°C).

1. Verify that AC power is switched OFF at the power source
before beginning.
2. Remove the junction box cover (two screws).
3. Use appropriate electrical conduit and fittings to route AC power
wire into the junction box. Run high voltage power wiring in separate
conduit from low voltage signal wiring.
4. Connect the power wires to the transformer wires with wire nuts
(see color code chart), and replace junction box cover.
5. Installer is responsible for local electrical codes and wiring.

1. Use approximately 6 ft. (2 m) of 18 AWG (1 mm) 5-conductor
sprinkler wire to connect interface to the controller.
2. Strip wires approximately
3 16
" (4.5 mm) and attach to interface, by
color, at the To Controller section of the terminal strips.
3. Route wire (in separate conduit from AC power) to the controller.
With controller power OFF, strip wire ends approximately ¼" (6 mm)
and connect by color code to the ICC power module
terminals as shown.
