PLANNING
It is very important to plan where the OmniTouch touchscreen will be installed and the
gauge/type of wire you will use for the installation. In selecting a place to mount the
touchscreen, be sure to avoid an area where studs, plumbing, or electrical wiring may be located
behind the wallboard. It should be mounted so that the display is at or slightly above eye level.
The touchscreen requires a minimum of 4 wires for operation (2 for power and 2 for
communications). The required distance between the controller and the touchscreen will
determine the wire gauge/type you should use. To prevent the touchscreen from drawing more
than the specified maximum current from the controller’s power supply, do not exceed the
"Maximum Cable Length" based on the wire gauge/type per the table below (Table 1).
MAXIMUM CABLE LENGTH BASED ON WIRE GAUGE / TYPE
Wire
Gauge Solid/ Stranded Number of positive conductors Number of ground conductors Maximum Cable Length (feet)
24 solid 1 1 113
24 solid 2 2 227
24 solid 3 3 340
22 solid 1 1 180
22 solid 2 2 360
22 stranded 1 1 166
20 solid 1 1 287
20 stranded 1 1 267
18 solid 1 1 456
18 stranded 1 1 420
16 solid 1 1 724
16 stranded 1 1 669
Table 1
If cable with multiple conductors is used (such as Cat-5 cable), it is possible to connect multiple
conductors together to achieve greater distance. For example, using only one of the 24 gauge
conductor in the Cat-5 cable for power (1 for positive and 1 for ground), the maximum distance
between the controller and the touchscreen is 113 feet. If you were to connect 2 of the 24 gauge
conductors together (2 for positive and 2 for ground), the maximum distance between the
controller and the touchscreen is then 227 feet. If you were to connect 3 of the 24 gauge
conductors together (3 for positive and 3 for ground), the maximum distance between the
controller and the touchscreen is then 340 feet.

INSTALLATION
Hold the template (Installation Template – 32A10-1) against the wall so the top edge is at the
appropriate height and parallel to the floor. Using a Punch, or similar instrument, punch
through the center of each tick mark (+) on the template.
Drill a 1/4" hole at each punch mark. Using a pencil, draw a line around the quadrant of each
hole as shown as shown. Carefully cut along the pencil line.
4"
5 3/8"
DO NOT OVERSIZE THIS CUTOUT!
Remove the faceplate from the touchscreen by grasping the top and bottom edges of the
faceplate and carefully lifting the bottom edge away from touchscreen housing.
Run the power/communications cable (as determined by Table 1) from the controller location to
touchscreen location. Attach the wires to the supplied COMM cable assembly using the
supplied wire spice connectors.
Insert the COMM cable assembly through the rectangular cutout in the touchscreen backbox
and plug into the mating connector (J6) on the touchscreen.

3
Locate the retaining flange screws in the upper left and lower right corners. Turn the screws
counterclockwise until the gap between the retaining flange and the housing flange is wider
then the wall.
WALL
Place the assembled unit into cutout in the wall.

4
Turn the retaining flange screws clockwise until they are snug (do not over tighten).
WALL
Before installing faceplate, remove the protective film from the LCD area of the touchscreen.
Fasten the faceplate onto the touchscreen by hanging the top of the faceplate on the top edge of
the touchscreen, then gently snapping the bottom onto the touchscreen.
REMOVING THE TOUCHSCREEN
After installation, if it is necessary to remove the touchscreen from the wall, turn retaining
flange screws 1 turn counterclockwise.
Note: Do not turn the retaining flange screws more than 1 full turn counterclockwise; otherwise
the retaining flange may fall off into the wall.

5
CONNECTING TO OMNI II / OMNIPRO II
Connect the "Yellow" and "Green" wires from the touchscreen to the "A" and "B" terminals
under the section marked "CONSOLE" on the controller, respectively. Connect the "Red" and
"Black" wires from the touchscreen to the "12V" and "GND" terminals under the section
marked "AUXILIARY" on the controller, respectively.
A maximum combination of 8 touchscreens and consoles can be used with Omni II and a
maximum combination of 16 with OmniPro II.
NOTE: Do not exceed the maximum current limitation of the controller. If more than 2
touchscreens are used, the additional touchscreens must be powered from an external
power supply. THE EXTERNAL POWER SUPPLY MUST BE GROUNDED TO THE
CONTROLLER EARTH GROUND TO AVOID DAMAGE TO THE TOUCHSCREEN.

CONNECTING TO OMNILT
Connect the "Yellow" and "Green" wires from the touchscreen to the "YEL" and "GRN"
terminals under the section marked "CONSOLE" on the controller, respectively. Connect the
"Red" and "Black" wires from the touchscreen to the "12V" and "GND" terminals under the
section marked "AUX" on the controller, respectively.
A maximum combination of 4 touchscreens and consoles can be used with OmniLT.
NOTE: Do not exceed the maximum current limitation of the controller. If more than 1
touchscreen is used, the additional touchscreens must be powered from an external power
supply. THE EXTERNAL POWER SUPPLY MUST BE GROUNDED TO THE
CONTROLLER EARTH GROUND TO AVOID DAMAGE TO THE TOUCHSCREEN.

ADDRESSING THE TOUCHSCREEN
OmniTouch touchscreens are connected to the same communications bus as HAI consoles.
Each console and touchscreen must have a unique address. The default address setting of the
touchscreen is "1".
When power is first connected to the touchscreen, if the touchscreen isn’t addressed properly
(other consoles or touchscreens already occupy the touchscreen address) or isn’t communicating
with the controller, the following page is displayed.
To assign an address to the OmniTouch touchscreen, press and hold the HAI logo for three
seconds. The "Touchscreen Address" page is displayed.
This page allows the installer to adjust the brightness and contrast of the touchscreen and assign
the touchscreen address.

8
Press the [up arrow] button to raise the current setting and the [down arrow] button to lower the
current setting. When complete, press the [exit] button in the lower-right corner to save the
settings and exit.
Once the touchscreen is properly configured and communicating with the controller, other
configuration items may be configured using the "Screen Setup" page. To access the "Screen
Setup" page, from the Home page, touch the [Setup] icon. See the Touchscreen User’s Guide
(32R00-1) for additional information on these items.
Note: In the event of an AC Power failure and the HAI controller is running on backup battery
power, the touchscreen display will be lowered to its lowest viewable setting. Do not try to
adjust the “brightness” and “contrast” levels. When AC Power is restored, the touchscreen
display will automatically return to its correct settings.
RESETTING THE TOUCHSCREEN
If for any reason the touchscreen needed to be reset, remove the faceplate and press the reset
button marked "SW1" on the circuit board below the LED.
