V-IP RT
Alarm Input
This menu allows configuration of the alarm settings, refer to ‘Installing the DV-IP RT Unit’ for
hardware installation guidance.
Number
This identifies which input is being configured. The unit supports
20 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 wil ltrigger 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
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 first alarm has finished 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.
