ALARMS - ARMING NOTES

Associating Alarms with Camera Salvos

Each alarm contact may be associated with a camera salvo for
callup when the alarm is received. Camera salvos can be
defined either by the System Salvo menu, page 4-8, or by the
Connect Next feature of the Alarm Contacts menu, page 4-12.
To call camera salvos, the alarm contacts must be associated to
a monitor block that contains sufficient monitors for the
number of cameras in the salvos (see Monitor Block, below).
Note: If there are more cameras in the salvo than monitors in
the block, the cameras at the end of the salvo with no
matching monitors are not shown.
When camera salvos are called to a monitor block, several
alarm response actions are restricted.
• If the first monitor of the block is armed or enabled for
Manual Clear, the keyboard must call the first monitor of
the block displaying the salvo to acknowledge the salvo.
• During display in Sequence or Hold method, the keyboard
must call the first monitor of the block displaying the salvo
to shift the salvo back to the queue with the NEXT key.

Associating Alarms with Monitor Blocks

Each alarm contact may be associated with a block of monitors
for display of associated camera video inputs when the alarm is
received. Monitor blocks permit the distribution of multiple
alarms over several monitors for simultaneous viewing.
• The desired monitor block(s) must be defined first, using the
Monitor menu, page 4-16.
- The ARM TYPE (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 first monitor of the block only.
- The Queuing method may be set as desired for each
monitor of the block (see below).
• Associate alarm contacts with the first monitor of the
monitor block only, using the Monitor/Contact Access menu,
page 4-26 (or keyboard commands, page 3-6).
Note: Do not arm any contacts to the remaining monitors
of a block.

Monitor Block Queuing For Single Cameras

For alarm contacts that are associated with single camera
callups only, there are no restrictions on the type of alarm
queuing used in a block. Both Block Sequence and Hold
arming codes may be intermixed within a block to provide
varied viewing patterns.

Monitor Block Queuing For Camera Salvos

The use of monitor blocks is required when camera salvos are
associated with alarm contacts in order to view all cameras in
the salvo. Any monitor block associated to the alarm contact
must include sufficient cameras for these camera salvos.
Block Sequence and Hold queuing may be mixed in a monitor
block, but there are restrictions on the way these codes are set.
• 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 camera 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
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 Callups

Multiple alarm contacts may be associated with the same
camera, with different auxiliary and preset calls (see Set Alarm
Contacts menu, page 4-12). If more than one of these alarm
contacts is received during the same time period, the system
will activate each preset and auxiliary for the same camera in
the order that the alarms are received, stopping at the preset
and auxiliary of the last received alarm contact. In this
instance, the operator may not see the first preset or auxiliary
action(s).

Wired Alarm Contact Sets

Contiguous alarm contacts may be grouped into Wired sets
(Set Alarm Contacts menu, page 4-12). All contiguous Wired
ACNs are activated when any alarm contact of the set is
received. Each ACN in the set is then handled as a separate,
active alarm for the monitor it is armed to, in accordance with
the Arming Code armed for each monitor.
• If the associated monitor is armed for Instant or Auto clear,
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 acknowledged, or the "*"
feature of the Alarm Contact CN field (see page 4-12) may
be used to clear all alarms in the Wired set.
