Figure 3-10. DBB Connectors
These connectors are used as follows:
• CUST ALM - Allows you to connect to an external alarm source. This
connector replaces the 10-pin jack labeled EX AL on the standard transition
board. To make this connection, use Cable No. 5956-165M. (This cable must be
ordered separately from Milgo.) On this connector, Pin 1 (top right) is the high
true (+5V) alarm input and pin 4 (top left) is the low true (0V) alarm input. Pin 2
(middle right) is the ground.
