30.2. Communication
The system supports the following communication methods and protocols:
• GPRS network – EGR100, Kronos protocol.
• Voice calls (GSM audio channel) – Ademco Contact ID protocol.
• RS485 data channel.
• CSD (Cricuit Switched Data).
• SMS – Cortex SMS format.
Any communication method can be set as primary or backup connection. The user can set up to 4 backup connections in any sequence order.
Initially, the system communicates via primary connection with the monitoring station. By default, if the initial attempt to transmit data is
unsuccessful, the system will make additional attempts until the data is successfully delivered. If all attempts are unsuccessful, the system
will follow this pattern:
a) The system switches to the backup connection that follows in the sequence (presumably - Backup 1).
b) The system then attempts to transmit data by the backup connection.
c) If the initial attempt is unsuccessful, the system will make additional attempts until the data is successfully delivered.
d) If the system ends up with all unsuccessful attempts, it will switch to the next backup connection in the sequence (presumably - Back-
up 2) and will continue to operate as described in the previous steps. The connection is considered unsuccessful under the following
conditions:
• GPRS network – The system has not received the ACK data message from the monitoring station within 40 seconds.
• Voice calls:
• The system has not received the “handshake” signal from the monitoring station within 40 seconds.
• The system has not received the “kissoff” signal from the monitoring station within 5 attempts each lasting 1 second.
• CSD – The system has not received the ACK data message from the monitoring station within 35 seconds.
• SMS – The system has not received the SMS delivery report from the SMSC (Short Message Service Center) within 45 seconds.
e) If one of the attempts is successful, the system will transmit all queued up data messages by this connection.
f) The system then returns to the primary connection and attempts to transmit the next data messages by primary connection.
g) If the system ends up with all unsuccessful attempts by all connections, it will wait until the
Delay after last communication attempt
time (By default – 600 seconds) expires and will return to the primary connection afterwards.
h) If a new data message, except Test Event (ping), is generated during
Delay
after last communication attempt time, the system will
immediately attempt to transmit it to the monitoring station, regardless of
Delay
after last communication attempt being in progress.
