Redundant transmission
For redundant transmissions, the LAN connection is usually set as the primary
path and the GPRS module as the redundant path. The GPRS module can also
be set as the primary path in the AZWG10200-PSTN/IP CONVERTER. If the
primary path experiences a fault, the redundant path automatically takes over
the monitoring times of the primary path. The most commonly used versions
are listed below.
 DP-1 (comparable to class A/B)
o
LAN: a test notification is sent from the alarm system via the A/B
converter every 24 hours
o
GSM: a test notification is sent from the AZWG10200-PSTN/IP
CONVERTER every 24 hours
 DP-3 (comparable to class C)
o
LAN: an SIA poll notification is sent every 60 seconds
(monitoring 180 seconds)
o
GSM: an SIA poll notification is sent every hour (monitoring
25 hours)
o
If the primary path experiences a fault, the redundant path
automatically takes over the monitoring times of the primary path
and a poll notification is transmitted every 60 seconds
The receiver at the monitoring station monitors the poll notifications and
reports the status and failure.
Installation and connection
The AZWG10200-PSTN/IP CONVERTER is connected to the analogue telephone
connection of the alarm system and/or the alarm lines. The connections comprise the
power supply, Ethernet, GSM antenna (optional), converter (optional) and/or signal
lines, the relay outputs and the tamper contact of the AZWG10200-PSTN/IP
CONVERTER.
