Installation and Trim
The ISK1 Keypad is designed to install in a standard US
electrical plastic wall box with an internal volume of at
least 18 cubic inches (295 cm
3
). The keypad occupies a
single gang and accepts a Decora
®
wall plate. For the
best accessibility, viewability, and microphone reception,
we recommend installing the keypads at a standard ther-
mostat height of 58 to 60 inches (1.5 m). This may vary
according to personal preferences or requirements.
Wiring
ComPoint system components interconnect with CAT-5
cable. Run CAT-5 from the hub location to every keypad
location. If the ComPoint system is sharing speakers
with an audio system, loop the speaker cables through
the keypad locations. If dedicated speakers are being
used, run the speaker cables to the keypads.
When running CAT-5 and speaker cables, avoid running
them near AC power wiring. If you have to run the
cables parallel to electrical wiring, space the cables at
least two feet (0.6 m) from the AC power lines.
Connections
The keypad provides a 110 punch-down connector for
the CAT-5 cable. Use a punch-down tool to connect the
wires according to the connector color code as shown:
The keypad also has an 8-pole screw-terminal connector
for accessing the internal speaker relay. The speakers
connect to the output terminals. The input connectors
are used for connecting an audio system amplifier when
it shares the speakers with the keypad.
Note:
Both speaker output channels must be connected,
since they are wired in series. If you are using only one
dedicated speaker, connect the speaker to one channel
and connect a shorting jumper or a 2-watt power resis-
tor of up to 8 ohms to the other channel. If the CAT-5
cable to the keypad is short, a jumper will suffice. If the
CAT-5 is long, use a resistor instead to reduce the load
on the keypad amplifier.
Be sure to observe correct polarity when connecting the
speaker wires. The standard color code for 4-conductor
speaker cable is as follows:
Wire Color Polarity
White Left +
Green Left –
Black Right –
Red Right +
Backlight Color Selection
To select the keypad backlight color, use the miniature
slide switch located on the bottom edge of the first cir-
cuit board behind the keypad yoke.
For more information, see the ComPoint system manual.
