when this detects a line supervision failure, configure the IPDACT to
take no actions whatsoever.
The panel’s
PRI. PHONE LINE
has converted into an IP line. All
alarms sent over the
PRI. PHONE LINE
are captured and
transmitted over the IP network.
•
If the IP line supervision detects connectivity failure, the IPDACT
switches its relays so the PSTN input connects to the TO-AP output
i.e. connects the telephone network to the panel’s
PRI. PHONE LINE
input. However given that the PSTN input is not operative, there isn’t
a line. Nor is there a telephone line to the panel’s
PRI. PHONE LINE
input. This situation provokes an alarm in the panel, which is then
sent to the central. This is how the panel detects IP connectivity
failure.
•
Apart from the IPDACT supervising the IP line, the control panel
must, in order to comply with the UL, have receiver supervision
functionality configured. The IPDACT treats the supervision as an
attempt to send a signal.
•
The user installations will have telecommunication devices which
allow the IP module to reach Internet.
For UL Listed Fire Installations, shared on-premises
communications equipment is required to be UL Listed for
Information Technology Equipment.
