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 117).
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.
)
The Restore Signals option in Engineer 2-5-2-5 (page 118) determines whether
restore messages are sent to the ARC.
)
The Tampers As Alarm/Tamps option in Engineer 1-9-3 (page 91) determines
whether tamper conditions are sent as event code 130 or 137.
Table 5 (see page 112) shows the events that are transmitted to the ARC, depending on
the reporting level set in option 2-5-2-6 (page 119).
4 to 7 – SIA 1, SIA 2, SIA 3 and Extended SIA 3
The SIA formats automatically transmit data from the event log to the ARC. The four SIA
formats differ in the amount of data transmitted with each message:
SIA1 format is: #AAAAAA|NCCcc
SIA2 format is: #AAAAAA|Nidnnn/rinn/CCcc
SIA3 format is: #AAAAAA|Ntihh:mm/idnnn/rinn/CCcc
#AAAAAA|AS
Extended SIA 3 format is: #AAAAAA|Ntihh:mm/idnnn/rinn/CCcc/AS
Where:
AAAAAA = 6-digit programmable account code (e.g. 123456), as specified in option 2-5-
2-3 (page 117).
N = New Event (always N).
tihh:mm/ = time (e.g. ti10:23/).
idnnn/ = user number, if applicable; otherwise not sent (e.g. id123/ or id6/).
rinn/ = ward no. (e.g. ri12/ or ri3).
