Engineer Menu 2-5 Engineering Manual
92
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 2-5-2-5 (page 98). 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
43. 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 97) determines whether
restore messages are sent to the ARC.
3 – Contact ID
The Contact ID format automatically transmits data from the event log to the Alarm
Receiving Centre (ARC). Examples of messages that use the Contact ID format are:
Example 1 - 1234 18 1137 01 015 2
1234 is the account number, as specified in option 2-5-2-3 (page 96).
18 is the message type used to identify the message as Contact ID.
1137 is the event qualifier for a new event (1), followed by the event code for a
system tamper alarm (137).
01 is the ward number.
015 is the zone number.
2 is the checksum value, which the ARC needs to verify to confirm a valid message
has been received.
Example 2 - 1234 18 3137 01 015 F
The only difference between this and the first example, is the event qualifier of 3 to
indicate a restore of a system tamper alarm, and the checksum value.
