2.8 Digital Communicator
Two independent telephone lines can be connected to the control panel. Telephone line
control/command is made possible via double line seizure as well as usage of an RJ31X
style interconnection. Note that it is critical that the panel's digital communicator be
located as the first device on the incoming telephone circuit to properly function.
Important! The DACT must not be used to dial a phone number that is call-forwarded.
The control panel's digital communicator is built into the main circuit board.
Connection and wiring of two phone lines is required as shown below.
