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 32

alarm inputs.

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.

Module The alarm contacts are connected via modules. Select the module that

the contact to be congured is in.

Contact Select the Contact within the module to congure.

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.

EOL The End Of Line (EOL) option enables the inputs to detect any

changes in the electronic input resistance. A change outside the

expected values will result in a Tamper Alarm (short circuit or open

circuit) being detected and the system switching to alarm mode.

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.
