HARDWIRE CONNECTION (IMMS-CI-HW) .........................................................................
IMMS-CI has hardwired input over GCBL cable, from either the
Site Interface (SI), or a previous CI. If IMMS-CI will have radio
communications, refer to instructions with IMMS-R radio option.
1. Route GCBL cable from SI direction through low-voltage conduit
into CI.
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 SI or Previous CI”, observing color codes.
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).
WIRELESS CONNECTION ......................................................................................................
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 dashes
(--). Blinking red dot shows normal
operation. No dot, or constant-on dot,
means microprocessor needs to be reset
(power off, then back on).
The button allows the Controller Interface to receive an address from
the SI, and also to enter the diagnostic mode.
POWER AND TEST...................................................................................................................
GREEN BUTTON.......................................................................................................................
LED lights to the left of the display indicate Power, Controller, and
Comm and should appear in this order:
• “Power” shows AC is live to the interface.
• “Comm” lights when the interface is communicating with the
Site Interface.
• “Controller” lights after the interface is finished communicating with
the SI, and is downloading information into the controller.

1. Install all CI units and communications connections.
2. At the SI, press and hold the “B” button for approximately 5 seconds.
3. The SI 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.
The CI button is also used to start a diagnostic mode which performs
two tests.
Press and hold the button for approximately 3 seconds, until
“d1” appears.
• Run Station: The CI will automatically tell the controller to run
station 1 for 1 minute (checks communication between interface
and local controller). The green Controller LED will light as it
communicates to the controller.
• Radio check: Immediately after the Run Station command is
sent to the controller, the radio (if one is installed) will transmit a
continuous tone for 5 seconds that can be heard on a handheld radio
on the same frequency (verifies operation of radio, no effect in non-
radio units).
TO ADDRESS CONTROLLER INTERFACES..........................................................................
DIAGNOSTIC MODE.................................................................................................................
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 CI display will occasionally show “P1” or “P2” when connected
to the SI. “P1” or “P2” shows that the unit is being “polled” by the SI
and that communications are working.

If the wrong address is set, reset the interface memory by
disconnecting the green three-wire power terminal. Press and hold
the green button, and plug the power terminal back in. Continue
holding the button until the test display “88” disappears, and release.
The display will show the version number for a moment, then the
“—“ display. Repeat the Controller Interface Address procedure to
enter the correct address.
INTERFACE RESET ..................................................................................................................
Turn off or disconnect AC power plug before making any connections
inside the CI!
ADDITIONAL CONNECTIONS ................................................................................................
1. To connect to additional Controller Interfaces, route, strip, and
connect GCBL cable to the lower section of the CI communications
terminals in the same way that the incoming connection was made.
2. Connect the bare silver ground wire in the GCBL to the ground lug.
3. Continue the GCBL run to the next interface (IMMS-CI) in one
continuous run, if possible, with no breaks or splices in the
communications, and continue the installation.
CONNECTIONS TO OTHER INTERFACES ............................................................................

1. Connect only Hunter Clik-family sensors to IMMS. Refer to sensor
documentation for correct installation of sensor and permissible
wire runs.
2. Route sensor wires into the cabinet through low-voltage conduit,
and strip wire ends approximately 3⁄16" (4.5 mm).
3. Connect one wire from sensor to “Sensor 1” position on upper
terminal strip.
4. Connect other sensor wire to “Sensor Common”.
5. Up to 3 sensors may be connected to the CI. Connect one wire from
each additional sensor to terminals “Sensor 2” and “Sensor 3”, and
connect the other wire from each sensor to the “Sensor Common”.
CONNECTION TO OPTIONAL CLIK SENSORS ....................................................................
POWERED SENSORS ..............................................................................................................
Hunter’s Wireless Rain-Clik™ and the Flow-Clik IMMS require 24VAC
power over their yellow wires.

1. Route the receiver cable through the low-voltage conduit.
2. Strip and connect the 2 yellow power wires from the sensor receiver
to the power terminals in the interface.
3. This will double the yellow wires in each terminal, one each from the
interface transformer, and one each from the sensor power.
4. Route and connect the white sensor signal wire to the desired sensor
input, and the blue wire to the Sensor Common. The orange wire is
not used in an IMMS™ connection.
