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.

IMMS-SI can have two types of
communications from the computer.
IMMS-SI-HW has hardwired input over
GCBL cable, from a CCC installed at the
computer. IMMS-SI-MOD connects to a
standard telephone jack with a dedicated
analog line (must have dial tone).
1. Route GCBL cable from CCC through low-voltage conduit into SI.
2. Strip black outer jacket and excess foil shield back approximately
2" (50 mm).
3. Strip approximately 3⁄16" (4.5 mm) from each individual wire and
connect to top half of communications terminals, in area labeled
“From CCC”, observing color codes.
IMMS-SI COMMUNICATIONS CONNECTIONS ..................................................................
HARDWIRE CONNECTION (IMMS-SI-HW) .........................................................................
4. Connect bare silver ground wire in GCBL to ground lug at earth
ground symbol.
5. Connect bare copper 10 AWG (2.5 mm dia.) wire from ground lug to
proper earth ground (recommended impedance 10 Ohms or less).

1. Route RJ-11 telephone cable through low-voltage conduit into SI.
2. Connect straight up into receptacle below terminal strips, indicated
by “Telephone” pointer, until “click” indicates the connection is
locked into place.
3. Connect other end to service telephone jack. See modem country
code selection process in the diagnostics section.
Refer to instructions included with the optional wireless kit.

1. Connect bare copper 10 AWG (2.5 mm) Earth Ground wire to
grounding terminal where labeled in interface.
2. Route ground wire through low-voltage conduit and secure to
8 ft. (2.5 m) copper-clad ground rod, driven vertically into earth.
3. Ground connection should have recommended resistance of
10 Ohms or less.
EARTH GROUNDING ................................................................................................................
Basic connections are complete after these
steps. Apply AC power to the interface
and observe display. Display should
automatically show test pattern, then version
number, and then address (always “01”
on Site Interface). Blinking red dot shows
normal operation. No dot, or constant-on
dot, means microprocessor needs to be
reset (power off, then back on).
POWER AND TEST ...................................................................................................................
LED lights to the left of the display indicate Power, Controller,
and Comm.
• Power shows AC is live to the interface.
• Comm lights when the interface is communicating with the
central computer.
• Controller lights after the interface is finished communicating with
the computer, and is downloading information into the controller.

1. Install all additional CI units in accordance with their instructions
(see “Connections to Other Interfaces”) and install communications
connections.
2. At the SI, press and hold the “B” button for approximately 5 seconds.
3. The display will enter the “racetrack” mode (lights move around
perimeter of display). It will remain in this mode until you press “B”
again, or until it receives communications from a central computer.
4. With the SI in racetrack mode, visit each CI in order, from the lowest
number to the highest number.
5. Press the single green button in the CI once, and the SI will assign it
the next available address. Pressing the button causes the SI to see
and number the CI.
6. Because the SI is always “01”,
the first CI will automatically
receive address “02”. The
next CI will receive address
“03”, etc. When finished with
all CIs, return to the SI and
press “B” again to exit the
racetrack mode and resume
normal operations.
The buttons allow the SI to address the Controller Interfaces in the
system, and various diagnostic modes.

TO ADDRESS CONTROLLER INTERFACES ..........................................................................
Site Interface Reset
To completely clear the SI memory and renew addressing of CIs from
the beginning, reset the SI by disconnecting the green three-wire
power terminal. Press and hold both green A and B buttons in, and
plug the power terminal back in. Continue holding the two buttons for
about 1 second after restoring power, and then release. The display
will show the version number for a moment, and then the automatic
“01” address of the SI.
The SI memory will now be reset, and addresses for new Controller
Interfaces will begin with “02” when the SI is placed in the racetrack
addressing mode.
