CenTral sofTWare and aCC-aGC CommunICaTIon modules ..
The ACC-COM-xxx module provides communications
for ACC/AGC series controllers. It can be used to
communicate with a remote computer via hardwire cable
(ACC-COM-HWR), dial-up telephone (ACC-COM-POTS)
or cellular phone (ACC-COM-GSM in North America, or –
GSM-E for international). This module may be installed in
wall mounted or pedestal mounted controllers.
theOry Of OPerAtIOn
The Com module is a communications manager. It will
contain the controller's unique identification (address),
and enables communications into and out of the controller
when combined with other devices. The Com module also
coordinates communications between external devices
and the ACC controller facepack.
The Com module may also communicate with other
controllers, via optional RAD3 UHF radio modules (sold
separately) with antenna for wireless communications,
and/or an ACC-HWIM hardware interface module (sold
separately) for hardwired communications over Hunter
GCBL cable.
ACC-COM-POTS has dial-up communications ability
built-in, but may also require the additional modules for
outbound radio and/or hardwire connections with other
controllers.
ACC-COM-GSM (-E) has cellular communications built-in,
but requires a SIM card from the cellular provider, and
may also require the additional ACC-HWIM and/or RAD3
modules for outbound radio and/or hardwire connections
with other controllers.
Any Com module combined with a RAD3 radio installation
will respond to Maintenance Radio commands from a UHF
portable radio, equipped with a DTMF keypad.
Any Com module combined with a RAD3 radio installation
will respond to Maintenance Radio commands from a UHF
portable radio, equipped with a DTMF keypad.
ACC Com modules have no effect on ICR (or SRR) remote
control. The ICR and SRR remotes will work directly with
ACC, whether a Com module is installed, or not.
The ACC-COM-POTS enables dial-up telephone
communications via standard analog telephone line. It
can also enable either UHF radio communications, or
hardwired cable communications, or both. The hardwire
and radio options require other components to work.
Each communications option has different physical
requirements.
Dial-up Telephone: Plan ahead for routing a telephone line
into the controller. ACC-COM-POTS accepts a standard
4-wire RJ-11 telephone jack, but should be located within
77
6 ft./2m of the telephone outlet. Many trouble calls are
caused by exceeding the telephone wiring distance, and
routing telephone wires near electrically noisy equipment
(electric motors, fluorescent lighting, etc.). Dial-up
installations must be located as close to the telephone
connection as possible. All outdoor runs of telephone line
connections should be installed in metal conduit to reduce
interference.
Once an ACC controller is connected via telephone, it
can share the communications connection with other
controllers via radio and hardwire. The following
considerations apply to these optional outbound
connections.
uhf rADIO
The Communication Module ACC-COM-HWR,
ACC-COM-POTS, or the ACC-COM-GSM (E) does not
contain a radio. It is designed for use with a Hunter RAD3
UHF radio, which must be ordered separately.
The RAD3 radio will require an antenna, which is also sold
separately.
In steel enclosures, the antenna must be installed
externally (signals will not communicate from inside a
metal box).
• Plan ahead for mounting an external antenna. It will be
necessary to route the antenna cable from the radio
module inside the enclosure, to the antenna outside of
the enclosure. A site survey with comparable radios
is required before a final decision can be made about
antenna types and placement.
In the plastic pedestal enclosure, the Hunter IMMS ANT 2
antenna is designed to be mounted in the pedestal lid and
may be adequate for communications (to be determined in
advance by site survey).
In North America and most other countries, a license
is required before operating any radio transmission
equipment. Verify your local regulations and make
sure that you have obtained the proper licensing before
operating radio equipment.
