Inputs
This menu allows configuration of the alarm settings, refer to ‘Installing the Unit’ for hardware installation
guidance.
Number This identifies which input is being configured. The unit supports 19 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.
Module The alarm contacts are connected via modules. Select the module that
the contact to be configured is in.
Contact Select the Contact within the module to configure.
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.
