Monitor Arming
Armed monitors
are system monitors that are
configured to display alarm signals as they occur.
By arming a monitor, you define how it will display,
queue, and clear incoming alarms. Before arming a
monitor, you must understand the alarm display,
queue, and clearance methods.
Alarm Display Methods
Three alarm display methods are available: Single,
Dual, and Block Display.
Single Display:
Incoming alarms are displayed on
a single monitor. Multiple alarms received at a
single monitor will be displayed in sequence based
on the monitor’s queuing method.
Dual Display:
Incoming alarms are displayed on a
pair of monitors. The
hold monitor
receives the first
of a series of alarms. The
sequence monitor
receives subsequent and queues the incoming
alarms. After an alarm is cleared on the hold
monitor, the first alarm in queue on the sequence
monitor is moved to the hold monitor for viewing and
clearance.
Block Display:
Incoming alarms are displayed on a
group (block) of monitors. The first incoming alarm
is displayed on the first (lowest numbered) monitor
of the block. The second alarm is displayed on the
next lowest numbered monitor of the block, and so
on. When all monitors in a given block are
displaying alarm video signals, all subsequent
alarms are held in queue until displayed alarms are
cleared.
Alarm Queuing Methods
Two alarm queuing methods are available:
Sequence and Hold Queuing.
Sequence Queuing:
Incoming alarms are
displayed in sequence on an armed monitor and
cycle continuously until each alarm is cleared. Each
alarm is displayed for a pre-designated dwell time.
Hold Queuing
:
An incoming alarm is displayed and
held on an armed monitor until it is cleared. All
subsequent alarms are queued in order until the
current held alarm is cleared.
Alarm Clearance Methods
Three alarm clearance methods are available:
Manual, Instant, and Auto Clear.
Manual Clear:
Pressing
Ack
clears an alarm.
Instant Clear:
An alarm is reset immediately at its
source (if the alarm has not already been manually
acknowledged). For example, a door opens and
activates an alarm. Closing the door clears the
alarm instantly.
Auto Clear:
An alarm is reset at its source after a
20 second delay (if the alarm has not already been
manually acknowledged). For example, a door
opens and activates an alarm. The door is
immediately closed, but the alarm will not clear
unless the door remains closed for a 20 second
interval.
Monitor Arming Codes
Arming codes are derived from the different
combinations of display, queuing, and clearance
methods. Based on the combinations, there are 16
codes, each with its own number and a three or four
letter acronym ID. The default arming code for all
monitors is disarmed.
