SIA L2 (SIA Level Two)
SIA Level Two is a modem based reporting format that is ideal for large scale integrated solutions such as the
Protege System. Comprising of a multiple message format and tonal acknowledgement the SIA (Security
Industry Association) format provides many reporting features ideal for access control, automation and large
burglary.
The SIA protocol is pre-defined and requires no further programming to operate with the exception of an
account code for an area or service that is running SIA. It is also possible to assign a special code to the zone
type being used for reporting if needed. The custom types are shown in the table following the zone types
assigned to each module.
Zones are reported using the standard burglary codes as detailed below. Openings, closings and other area
operations are reported used the area reporting codes.
Alarm / Open BA BR
Tamper BT BJ
Bypass BB BR
SIA Level 2 Message Format
The format of the SIA messages can vary greatly depending on the leading zero's configuration for each of the
various data code packets that can be sent. Given the large number of zones, users and areas the Protege
System attempts to use the maximum of these that is available. Some provision is provided to reduce the size of
these fields (Account Code to 4 Digits, Zone Numbers to 4 Digits) to allow easy integration with monitoring
software.
When configuring the automation software at the monitoring station for the information coming from the receiver
the following format should be used. In most cases a 4 digit account code can be set in the service and used as
default.
The first transmitted data is always the account code block, this is not shown and typically prefixed with a D or F
dependent on the size of the account code. This can be either 4 or 6 digits (D# or F#).
N ri GGG BA WXYZ ....
Where:
N Signifies a new event or an O will signify a old event that is being reported.
ri GGG The area or partition that is being reported from 000 to 999.
