Alarm Functions
The video switcher announces incoming alarms in several different ways, all of which can be enabled or
disabled individually, except for status group display:
Alarm list display on-screen
Flashing power LED
Buzzer
Status group display “A” (always active)
In addition to these local audible and visible announcements, a relay is available as a remote alarm output.
All alarm annunciations except the buzzer can be acknowledge manually or automatically. The buzzer, if it has
been enabled in the Setup Programming, must be acknowledged manually.
The Alarm Display
An alarm event may be announced on-screen with an alarm list display and codes displayed in the status
group. The alarm list may be enabled or disabled, but the status group is always active.
The Alarm List
If the alarm list has been enabled, an alarm event causes this message to be displayed in the lower half of the
monitor screen:
ACTIVE ALARM/FLASH-UNACK
X Y Z
where X, Y, and Z are camera numbers. The screen displays as many alarms as there are alarmed inputs.
The alarm input number flashes until acknowledged. The acknowledgment occurs manually or automatically,
depending on the state of Auto ACK in the Alarm submenu. Also, if any of the alarm inputs is active and Type
in the Alarm submenu is in the Latched mode, then the alarm list flashes and continues to flash regardless of
if the alarm input returns to an inactive state. The alarm list disappears from the screen either by auto or
manual acknowledgment.
