APPENDIX J: 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.
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.
