INSTALLATION
Product summary
As the central controller for the ComPoint
™
system,
the ISH1 Hub performs all communications routing.
It addresses the keypads and door stations accord-
ing to the ports they’re connected to.
The hub has ports for 6 zone keypads. Up to 6
ISH1 Hubs can be linked together for a maximum of
36 zones. With multiple hubs, each hub must be
assigned a unique ID number during installation.
The hub also has ports for 2 door stations. In a
system with multiple linked hubs, only the hub with
ID number 1 supports the door stations.
A separate doorbell chime tone can be selected on
hub 1 for each door. These chime selections take
effect for the entire system and play through all the
zone keypads.
The hub’s firmware contains lists of zone and door
labels for display on the ISK2 Advanced Keypads.
These labels are assigned by the installer using a
connected ISK2 keypad. (See the ComPoint system
manual for instructions on assigning labels.)
Designed for surface mounting or installation in a
structured wiring panel, the ISH1 Hub uses an exter-
nal model ISPS power supply to conserve chassis
space. It should be located near an electrical outlet.
The hub includes a port for updating its firmware
from a computer.
Wiring and connections
The ISH1 Hub connects to the keypads and door
stations with CAT-5 cable. The length limit for the
CAT-5 cable is 250 feet (76 m).
Run CAT-5 from the hub location to every keypad
and door station location. If you are installing
optional ISDR1 modules, loop the door station
cables through the module locations.
When running CAT-5 and speaker cables, avoid 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.
The hub has 8-pole modular jacks for keypad and
door station connections. These connections must
be made according to the T568A standard as
shown in the diagram below.
The hub also uses modular jacks for the link ports.
Use a short 8-pole, 4-twisted-pair straight-through
RJ-45 patch cable to link hubs together.
