Parameter 05: Group Number - Honeywell FBII CP-220A Hookup And Installation Instructions

PARAMETER 05:
Group Number
These two nearly
identical reports come
from two different
Subscriber Accounts. In
busy Central Stations
monitoring thousands of
alarm systems, the
limitations on the number
of subscribers that each
REC-11 Line Card can
process (over 65,000 with
hexadecimal in use) may
require that the same
Account Number be used
several times by different
subscribers. If such
"duplicate" subscriber
accounts were
programmed to call in on
different phone lines, the
Group Number, which is
part of the alarm report, is
used to distinguish them
from one another.

SLOT 1 IS IN GROUP 1
Background:
As previously stated, the CP-220A has eight internal slots for use with
either REC-1 or REC-11 FBI Line Cards. Each slot, in turn, has
corresponding phone line terminals at the rear of the Receiver. As a result,
your Central Station can connect up to eight separate phone lines – one per
slot and each with a different phone number – to receive incoming reports of
alarms and troubles from Subscriber Accounts.
Alternatively, another type of phone system, known as a Rotary or Rollover
system, may be used. In this type of arrangement, several or many lines are
accessed via the same telephone number, much like calls to a company's
switchboard. This kind of phone system automatically routes an incoming
call to the first available open (not busy) line. Programming PARAMETER
05 depends on the type of phone system in use.
Generally, when separate phone numbers are wired to a Central Station
Receiver, each Line Card slot corresponding to the connection is assigned a
unique Group Number. This Group Number, like the Receiver Number (see
PARAMETER 03), becomes part of the alarm (or trouble) report. By
assigning Group Numbers to Line Card slots in this manner, the same
Account Numbers may be used more than once for a given Receiver. Refer to
Figure 2-1.
