ALARM CONTACTS
The CM6800 provides a wide variety of alarm handling and display options. Alarmed
cameras can be displayed on one or several monitors as part of one or several alarm
groups (each monitor can display only one alarm group.) You can also customize the
system to handle alarms in the following ways:
• the order in which alarms are displayed
• automatic or manual acknowledgement of alarms
• activation of auxiliaries by alarms
• automatic activation of presets or patterns
• N.O. or N.C. operation
• priority assignment
Before programming alarm settings, verify that no automated system functions are set to
run, such as a macro that would arm or disarm an alarm. Ensure that system operators do
not arm or disarm any alarms while you are programming the alarm settings. If an alarm is
triggered while you are in the CM6800 programming screens, or while programming a
pattern, preset or zone, the system will exit the on-screen programming function and
display the alarm on the appropriate monitor(s).
When programming an alarm to appear on a specific monitor, verify that the monitor has
access to the camera view triggered by the alarm. Partitioning has priority over alarm
programming, so if an alarm is cued to a monitor that does not have access to the
appropriate cameras, the camera views cannot be monitored.
Alarm Contact Programming Tasks
To configure the CM6800 internal alarm contacts you must access the Alarm Contact
screen to complete the following minimum tasks:
• Enable the alarm contact.
• Specify at least one camera step with a dwell greater than zero for each alarm contact.
• Assign the alarm to at least one alarm group.
The following alarm handling options are set by factory default:
• Acknowledgement type = manual
•Time out = 10 seconds
• Alarm sensor type = N.O. (normally open)
• Priority level = 0
• Alarm group display option = Block Build
To change these defaults, or to configure external alarm contacts, refer to the following
sections for detailed programming instructions.
Alarm Group Display Options
To display on a monitor, an alarm must be assigned to an alarm group (A-H). Before
programming alarms you may want to determine the alarm display format for each
alarm group. An alarm can include up to eight steps, so eight camera views could
display as a part of each alarm.
A priority alarm appears on system monitors before non-priority alarms, despite the order
specified by the alarm group assignment. In the examples below, all alarms are at the same
priority level. Refer to the PRIORITY description in
Program Internal and External Alarms
.
NOTE:
You cannot access
the Alarm Contacts screen
when an alarm is active.
The message MONITOR:
00# IS IN ALARM. ACCESS
IS DENIED appears (the
appropriate monitor number
appears in place of “00#”).
