Alarm Input
This menu allows conguration of the alarm settings, refer to ‘Installing the Unit’ for hardware
installation guidance.
Number This identies which input is being congured. The unit supports 4
(four) on-board alarms.
Enabled Each input must be enabled to function. If the input is not enabled
and an alarm is received, the unit will not acknowledge the alarm.
N_O (Normally Open Contact) N_O indicates the non-alarm state of the input. Tick the N_O
checkbox to set the corresponding input to Normally Open. The
alarm will then trigger when the input is closed (shorted). If left as
Normally Closed (the default setting), the alarm will trigger when
the input is opened.
Pulse Ext (s) A pulse extension is used to prevent double triggers on a single
alarm. The pulse extension time starts on an alarm trigger. If that
contact is triggered again after the rst alarm has nished but
within the pulse extension, the second trigger will not restart the
alarm, but will extend the current alarm duration. Enter the time in
seconds for this extension.
