APPENDIX I: Alarm Arming Notes

Associating Alarms with Camera
Salvos
Each alarm contact can be associated with a camera
Salvo for call-up when the alarm is received. To call
a Salvo, the alarm contact number should be
associated with a monitor block that contains enough
monitors to display all of the cameras in the Salvo. If
not, the cameras at the end of the Salvo with no
matching monitors will not be shown.
Several alarm response actions are restricted when
Salvos are called to a monitor block:
•
If the first monitor of the block is enabled for Manual
Clear, the operator must call that monitor to clear the
alarm.
•
During display in either Sequence or Hold method,
the operator must call the first monitor of the block
displaying the Salvo in order to shift the Salvo back.
Associating Alarms with Monitor
Blocks
Each alarm contact can be associated with a block of
monitors to display alarm video. Monitor blocks
permit the distribution of multiple alarms over several
monitors for simultaneous viewing.
Consider the following when associating alarms with
monitor blocks:
•
The desired monitor block(s) must be defined first.
•
The Monitor Arming Code for each monitor in a
block must be set to a Block code.
•
The alarm clearance method for the block is set by
the arming code for the first monitor of the block
only.
•
The queuing method can be set as desired for each
monitor of the block.
•
Associate alarm contacts with the first monitor of the
monitor block only.
Monitor Block Queuing for Single
Cameras
No restrictions exist on the type of alarm queuing
used in a block when alarm contacts are associated
with single camera call-ups only (not Salvos). Both
Block Sequence and Hold queuing methods can be
intermixed within a block to provide varied viewing
patterns.

ADMINISTRATOR'S GUIDE
Monitor Block Queuing for Camera
Salvos
Monitor blocks are required to be able to view all
cameras when Salvos are associated with alarms.
Block Sequence and Hold queuing can be mixed in a
monitor block with the following restrictions:
•
To arm a monitor block for Hold queuing with
Salvos, arm all monitors in the block to Block Hold.
•
To arm a monitor block for Sequence queuing with
Salvos, arm the first monitor of the block for Block
Sequence and the remaining monitors in the block
for Block Hold.
•
Multiple Salvos can be programmed for
simultaneous Sequence display within a monitor
block. First, identify separate, contiguous subsets of
monitors for Salvo displays. Then, arm the first
monitor of each subset to Sequence and arm the
remaining monitors in each subset to Hold. All
subsets should contain a sufficient number of
monitors to display the largest Salvo that could be
called to this block.
Auxiliary and Preset Alarm
Call-ups
Multiple alarm contacts can be associated with the
same camera using different auxiliary and Preset
views. If more than one of the alarm contacts is
received during the same time period, the system will
activate each Preset or auxiliary for the same camera
in the order the alarms are received (stopping at the
Preset or auxiliary of the last alarm contact received).
In this instance, the operator may not see the first
Preset or auxiliary action(s).

Wired Alarm Contact Sets

Continuous alarm contacts can be grouped into
Wired sets. All contiguous Wired alarm contact
numbers are activated when any alarm contact of the
set is received. Each alarm contact number in the set
is then handled as a separate, active alarm for the
monitor to which it is armed in accordance with the
arming code defined for each monitor.
•
If the associated monitor is armed for Instant or Auto
clear, then each alarm in the set is cleared
automatically when the source alarm is cleared.
•
If the associated monitor is armed for Manual clear,
each alarm in the set must be manually cleared.
