I - 1.2. Operation Mode
The IP Module (IPDACT) connected to the client control panel carries out two
tasks: sending alarms from the panel and monitoring the connection with the
IP receiver. The network backup option has implications in connection
monitoring. The alarms reception center is composed of two VisorALARM
devices, one main and the other backup. The IPDACTs release 2.2 onwards
has had their monitoring procedures modified in order to contemplate the
presence of two devices in the central.
I - 1.2.1. Monitoring
The IPDACT is a device that intercepts the control panel telephone
connection with two aims: firstly to detect when the panel sends an alarm in
order to capture it and retransmit over the connected IP network and secondly
to allow the telephone line to be used at the same time as sending alarms.
The interception of the telephone line takes place ONLY in cases where
connectivity with either of the Teldat VisorALARM devices has been verified.
The IPDACT-VisorALARM connectivity is checked through a traffic monitor
which the IPDACT periodically sends and to which the main Teldat
VisorALARM responds. (Through configuration, the main VisorALARM IP
