Appendix B Connecting the Controller
to the Telephone Line
Telephone Connections
Use one of two methods to connect the telephone line to the Controller. The first method uses the
Controller’s Phone and Line jacks, and is best suited to installations where direct access to
telephone line wiring is not available, or where a phone line is dedicated to the security system.
The second method uses the larger CA31A / RJ38A jack, and is better suited to installations where
there is direct access to the telephone line wiring.
About Jack Designations
Canada: The CA11A is a 4-conductor, Industry Canada approved, telephone line
interface connector
The
CA38A is an 8-conductor, Industry Canada approved, telephone line
interface connector
United States: The RJ11 is a 4-conductor, Federal Communications Commission (FCC)

The

RJ11 / CA11 Connections
Connect the incoming line from the telephone company to the Controller’s “Line” jack, and
connect the premises telephone equipment to the “Phone” jack CA11A. Use RJ11/CA11
connectors and 4-wire modular phone cord.
No telephone equipment, such as telephones, answering machines or fax machines,
should be connected between the incoming telephone line and the Controller’s “Line”
jack. If the incoming telephone line is removed from the “Line” jack, all telephone
equipment on the premises will be disconnected from the telephone line.

telephone equipment or jacks. Using 8-wire modular phone cord, make the telephone
connection to the Controller.
The CA38A / RJ38A jack features a built-in switch that will automatically reconnect the
premises telephone equipment when the plug to the Controller is removed from the jack.
