Mains Fail Delay
This option allows you to specify the length of time (0 to 60 minutes) that the control unit
must wait after detecting a mains supply failure before reporting Mains Fail to the ARC.
When the mains supply fails, the control unit lights the red alert LEDs around the
navigation key within a few seconds of the failure, activates any output programmed as
General Fault and logs the Mains Fail event (in the mandatory log).
Note:
Keypads do not show alerts while the system is set.
The control unit does not report mains interruptions of less than 9 seconds to the ARC. If
mains is restored within that time, the control unit switches off the red LEDs, deactivates
the General Fault outputs and logs Mains Restore.
If a mains interruption lasts for longer than 9 seconds, the subsequent additional actions
depend on the value in
Mains Fail Delay
:
If
Mains Fail Delay
is set to 0, the control unit starts an alert tone ten seconds after
the mains fail at the keypads and communicates a mains fail signal to the ARC
(provided a communicator is fitted). At the same time, the control unit activates any
outputs (including plug-by outputs) of type AC Fail.
If
Mains Fail Delay
is set to 1-60 minutes, the control unit starts the mains fail delay
time ten seconds after the mains fail.
If mains power is restored before the end of the mains fail delay, the control unit
switches off the red LEDs, deactivates any General Fault outputs and logs the
mains restore. The control unit does not send any report to the ARC.
If the mains fail condition is still present at the end of the mains fail delay, the
control unit starts an alert tone at the keypads and communicates a mains fail signal
to the ARC (provided a communicator is fitted). At the same time, the control unit
activates any outputs of type AC Fail.
A user can silence the alert by pressing the navigation key and entering a valid
access code. The keypad displays details of the alert. The General Fault and AC
Fault outputs remain active.
Once mains power is restored, the control unit deactivates any AC Fail outputs and
logs the mains restore. A user can reset the alert and deactivate any General Fault
outputs by pressing the navigation and entering the access code again.
Linked Zone Time
This defines the time within which two zones that have the
Linked Zone
attribute must
activate to trigger an alarm. See page 31. This option is available only if there is a zone
that has the
Linked Zone
attribute.
Panel Tamper Return
This option allows you to select either CC or FSL for the Tamper Return (TR) terminal on
the control unit's PCB. By default, the terminal is CC. If you select FSL, you should insert a
2k2 resistor in series with the tamper return wire from the sounder.
