Appendix A - Reporting Codes

The following tables contain Contact ID and Auto-
matic SIA format reporting codes. For more informa-
tion on reporting code formats, see section [360] to
[381]. For more information on individual reporting
codes, see sections [320] to [353] .

Contact ID

The first digit (in parentheses) will automatically be
sent by the control panel. The second two digits are
programmed to indicate specific information about
the signal.

For example, if zone 1 is an entry/exit point, you could
program the event code as [34]. The central station
would receive the following:

*BURG - ENTRY/EXIT - 1

where the “1” indicates which zone went into alarm.

SIA Format - Level 2 (Hardcoded)

The SIA communication format used in this product
follows the level 2 specifications of the

SIA Digital

Communication Standard

- October 1997. This format

will send the Account Code along with its data trans-
mission. The transmission would look similar to the
following at the receiver:

N Ri01

BA 01

= New

Ri01 = Area
