Relay Driver (Auxiliary Output) Connections
The UDACT's open collector output on TB3 (Comm Fail), is provided for Communicator Failure and
UDACT trouble. It can be used to drive UL listed relay MR-101/C or MR-201/C. The output is rated
for 40 mA. The normal condition for the output is Off (de-energized).
Communicator Failure occurs when the maximum number of attempts to reach both central stations has
taken place or when both phone lines are disconnected. UDACT trouble conditions include loss of
telephone line voltage to the primary and/or secondary phone lines, communication failure to the
primary or secondary Central Stations, total communication failure, entry into program, type and
troubleshoot modes.
Wiring from the UDACT terminal TB3 to the relay must be in the same room, no more than 20 feet in
length, and enclosed in conduit. Wiring from the relay output contacts must remain in the same room as
the UDACT.
When the UDACT is programmed for ‘Receive Only' (typically this occurs when annunciators are also
used and are set for 'Receive/Transmit'), the relay output is used to provide a UDACT trouble input to
the host control panel. For AFP-100, AFP-200, AFP-300, AFP-400, AFC-600, NFS-640, NFS-3030,
and AM2020/AFP1010 applications, use an FMM-1 module to supervise the relay closure (refer to
Figure 9 on page 26). Program the custom label field to read 'UDACT Trouble'. For System 500 or
System 5000 applications, wire the relay output to the annunciator trouble input circuit or use the relay
to trigger zone trouble.
When the UDACT is programmed for ‘Receive/Transmit', EIA-485 supervision and UDACT trouble
status are automatically handled by the host control panel. The relay output may, however, be used for
UDACT communications failure if desired.
