valid range is 1 – 99. If a high level or mimic panel alarm is being used, the
number is prefixed with an “H”. If a keyboard alarm is being used, the
number is prefixed with a “K”.
Enter the Subrack ID and press Enter on the keyboard.
For VideoBlox Subrack
, this ID represents the ‘V’+communication port
number to which the VideoBlox alarm concentrator AVBPIT is connected.
Valid range: ‘V’+maximum communication ports.

This field should be set to zero (0) when an alarm input module in a subrack
is used.
Enter a camera number or zero (0) and press Enter on the keyboard.
There are 8 separate alarm inputs for every subrack slot defined as an alarm
