FireNET FN-DAC Digital Alarm Communicator I & O Manual - v 1.0
2.5.4 Communication Failure
If all attempts to communicate to an account fail, the FireNET panel will display a
“Comms Fail” trouble condition, along with the number of the account that failed (1 –
4). The original event will be removed from the report queue. If there are additional
events to be reported the FN-DAC will attempt to report them, along with a
communication failure event. The panel will remain in a “Comms Fail” trouble
condition, but the FN-DAC will attempt to report any new events while in this state.
To clear the “Comms Fail” trouble from the panel display, press the panel Reset
button. This action will also generate a communication restore event that will be
reported to the monitoring station.
2.5.5 AC Fail Reporting
Per UL and NFPA requirements, an AC Fail trouble signal shall be transmitted after a
delay of between 60 and 180 minutes. The FN-DAC AC Fail delay time is
programmable up to 180 minutes, with a default setting of 60 minutes.
The AC Fail Report Delay is programmable from the front panel keypad or by using
Loop Explorer. For details on this setting, please see the
FireNET 4127 Installation
and Operation Manual
(part number 1700-09948).
NOTE
: The AC Fail Report Delay must be set to 60 – 180 minutes to be compliant
with UL 864 9
th
edition requirements.
