Alarm Input

This menu allows conguration of the alarm settings, refer to ‘Installing the Unit’ for hardware

installation guidance.

Number This identies which input is being congured. The unit supports

17 on-board alarms.

Note: The 4-input unit supports 5 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.

Note: If EOL alarms are to be used, this option should not be selected i.e. leave set as

Normally Closed.

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.
