Use this option to specify the communications format in which to send data to the ARC. Contact
the Alarm Receiving Centre (ARC)for the option that you should use. The following options are
available:
1 – Disabled
This option disables communications to the ARC. This option must be selected if a phone
line is not connected to the panel, otherwise "PSTN Line Fault" alerts will be generated.
2 – Fast Format
This is Scancom Fast Format; the format most widely used in the UK. When using the Fast
Format, each message transmitted to the ARC consists of the following:
A 4-digit or 6-digit account number. The account number is 1 for system, zone, user or
group output types. For ward output types, the account number is 1 for ward 1
events, 2 for ward 2 events, etc.
8 or 16 channels of data, as determined by option 2-5-2-7 (page 119). Each channel
communicates the status of an output, as programmed using the Digi On Board
outputs (page 41). The value of the channel can be:
1 = new alarm and not previously reported
2 = status of output is open/unset (Certain output types indicate an open/closed or
set/unset status, such as System Set, System Full Set and System Open; see page 44.
A value of 2 is used when the output indicates an unset status.)
3 = alarm restored and not previously reported
4 = status of output is closed/set (Similar to 2, but indicates the opposite status.)
5 = not in alarm
6 = in alarm but previously reported
A test signal.
)
The Restore Signals option in Engineer 2-5-2-5 (page 118) determines whether
restore messages are sent to the ARC.
