Alarm Connectors (DB-15)
Note:
The alarm connector, figure 1, is used to provide one
sensor alarm input for each camera input.
For easy operation, an alarm extension board,

connector.
Each alarm input requires two wires, one wire
connects to the desired alarm input pin, the
second wire connects to the multiplexer
ground. The alarm signal assignment is shown
