Alarm Inputs
This page is used to enable the alarm contacts used with the DV-IP.
On-Board Alarms - Alarm Inputs 1 to 16.
Contact - Alarm contact number.
Enabled - Enable the alarm contact.
Normally Closed Contact - Defines contact as normally closed.
Pulse Extension - Minimum duration of the alarm event in seconds. For example, if a door
with a pulse extension of 10 is opened triggering an alarm event, but closed immediately, the
alarm event will still last 10 seconds – and thus the increased recording rate lasts for the full
10 seconds rather than slowing again once the door is closed. If the alarm is opened twice
within the pulse extension period, this will only count as one alarm, rather than 2.
External Alarms - Module-1
Optional Alarm Inputs 17 to 32.
The optional RAM (CI01 Remote Alarm Module) provides 16 additional alarms inputs. The
Module must be set to Address 96 providing alarm inputs 17 to 32. Instructions are given
with the module on how to do this.
