Zone Alarm Input
Zones are groupings of alarm inputs. The zones allow an installer to arrange the inputs into a logical
order to allow a faster response.
This determines what input or system function will trigger the zone alarm. The options available are:
• No Contact - Default setting.
• Keywords - This allows keywords congured as an event trigger for a camera in the Text
Insertion Setup menu to be used as a zone trigger.
• Presets - When an alarm is triggered and a camera is sent to a preset position. It is possible
to use this to trigger a zone alarm input. This is used in conjunction with the Alarms and
Presets menu.
• VMD - If a camera has been congured for VMD or activity, it is possible to use this to
trigger an alarm zone. This is used in conjunction with ‘Activity Camera Setup’.
• System - There are a number of system features that can be used to trigger an alarm,
these include Panic, Disk low, Disk Full, Disk Low, Disk Fault (a disk failure and can be
congured to use the disk fault notication as a zone trigger), Fault Archive (if the automatic
archive process to either the internal CD/DVD writer or to an FTP server fails, the unit can
be congured to use failure notication as a zone trigger) and Slow Archive (will identify
when the continuous archive process is slow and use an alarm trigger to help ensure that
recorded images are not overwritten before being archived).
• General - These contacts are congured in the General Contacts section.
Zone OR Input
The Zone OR Input identies an alternative input that can also be used to trigger the zone alarm.
This means an alarm trigger can be received on zone alarm input or the zone OR input for the unit
to initiate the alarm actions. The allocated alarm trigger can be any of these options; Aux, Module 1,
VMD, Presets, System.
Zone AND Input
An alarm trigger must be received on both the zone alarm input and the zone AND input for the unit
to initiate the alarm actions. The allocated alarm trigger can be any of these options; Aux, Module 1,
VMD, Presets, System.
