Installation
Speaker connections
Each keypad has an 8-pole screw-terminal con-
nector for accessing the internal speaker relay.
This connector is typically used for connecting
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 speakers to the
output terminals.
Note:
Both speaker output channels must be
connected, since they are wired in series. If you
are using a single dedicated 8-ohm speaker
such as the ISSP ComPoint Speaker, connect
the speaker to one channel and a shorting
jumper to the other channel. If you are using a
single 4-ohm speaker, connect it to one channel
and a 4-ohm, 2-watt power resistor to the other
channel.
Be sure to observe 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 +
Hub modular connections
The hub has 8-pole modular jacks for keypad
and door station connections. The keypads con-
nect to ports 1 through 6, and the door stations
connect to DOOR1 and DOOR2. These connec-
tions must be made according to the T568A
standard as shown below.
The hub also uses modular jacks for the link
ports. You may use any 8-pole straight-through
RJ-45 patch cable to link hubs together.
Doorbell connections
ComPoint can operate a separate doorbell sys-
tem as well as provide doorbell chime tones in
the zones. To use a separate doorbell, connect
each door station to the doorbell as shown
below or in the doorbell system instructions.
