Contact status: Normally Open, Normally Closed

Note: Even though all alarm inputs can be accessed and set up, only those with active camera inputs are
processed for detection.
Alarm Outputs
The video switcher provides four different alarm output functions, and all but the LED (4) can be individually
programmed to meet the user’s requirements:
1. An alarm announcement is displayed on the monitor screen: ACTIVE ALARM/FLASH-
UNACK (followed by the numbers of the alarmed channels).
2. A buzzer sounds until manually acknowledged.
3. Two dry contact relays go active. These go active in response to an alarm on any input channel.
Multiple alarm inputs may be programmed to trigger an alarm.
4. The power LED on the front panel flashes when alarms are present in the system.
Various modes of acknowledgment may also be programmed. Lines F to I of the Alarm Inputs menu are
associated with alarm output functions:

Auto Acknowledgment Function
When Auto ACK is On, the switcher acknowledges an alarm event automatically. The acknowledgement time
(line F) is user selectable from 1 to 60 sec. Use the right and left arrow key to change the time.
Selection: On. Off
Buzzer
Alarm inputs from hardwired alarm devices can be programmed to cause a warning tone to be generated by
the video switcher. To set the buzzer, place the arrow cursor in front of the BUZZER, line G, and use the left or
right arrow keys to change the setting.
Selection: Enabled, Disabled
Manual Acknowledgment Functions
The manual acknowledgement function is used to acknowledge alarm events. To acknowledge an alarm,
press and hold the SHIFT key and then press the ACK key. The effects of the manual acknowledgment
depend on the number of alarms present and the setting of the Manual ACK option.
