Back Panel
The power pack connector is located at the right end of the back panel. This is a locking DIN connector. The remainder of the
back panel is divided into connectors for the two separate hybrids. Connectors are labeled with “J” numbers followed by “A”
or “B” to indicate System A or System B. For each hybrid, there is an AUX connector. This is used to connect to/from the
optional call signal card. Below the AUX connector, there are both a DB-9F connector and an RJ-11 connector for 4-wire
intercom connection. These are directly compatible with standard ADAM/Zeus keypanel cables. Next to the 4-wire
connectors, there is a 3-pin female XLR audio connector for connection to the 2-wire intercom system.
