Installation
Keypad backlight color selection
Each ComPoint keypad can be set to either
amber or green backlighting, selected by a
miniature slide switch on the bottom edge of
one of the circuit boards (figure 18).
Wiring and connections
ComPoint system components connect with
CAT-5 cable. Run CAT-5 from the hub location to
every keypad and door station location. If you
are installing ISDR1 modules, loop the door sta-
tion cables through the module locations.
Each keypad in the system requires one or two
external speakers. If the ComPoint system is
sharing speakers with an audio system, loop
the speaker cables through the keypad loca-
tions. If dedicated speakers are being used, run
the speaker cables to the keypads.
When running CAT-5 and speaker cables, avoid
AC power wiring. If you must run the cables par-
allel to electrical wiring, space the cables at
least two feet (0.6 m) from the AC power lines.
110 punch-down connections
The keypads, door stations, and door strike
release modules have 110 punch-down connec-
tors for the CAT-5 cables. Connect the wires as
shown in figure 19.
The keypad wire functions are as follows:
Wire Color Function
Brown Audio +
Brown/White Audio –
Green Status
Green/White Ground
Orange Ground
Orange/White + 15 VDC
Blue Com A
Blue/White Com B
Speaker connections
Each keypad also has an 8-pole screw-terminal
connector for accessing the internal speaker
relay. This connector is typically used for con-
necting the zone speakers in a multiroom audio
system. In a zone where the ComPoint system
does not share speakers with an audio system,
connect a dedicated speaker or pair of speak-
ers to the output terminals.
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 resistor of up
to 8 ohms to the other channel. If the CAT-5
cable to the keypad is short, a jumper will suf-
fice. If the CAT-5 is long, use a resistor instead
to reduce the load on the keypad amplifier.
Be sure to observe polarity when connecting
the speaker wires. The standard color code for
4-conductor speaker cable is as follows:
BR BR/W G G/W O O/W BL BL/W
BR BR/W G G/W O O/W BL BL/W
