Telephone Circuits
Provision to connect to two independent telephone lines is available via two
telephone jacks labeled PH1 (Primary) and PH2 (Secondary). Telephone line control/
command is possible via double line seizure as well as usage of an RJ31X style
interconnection. (RJ31X jacks must be ordered separately).
Note: It is critical that the UDACT-F be located as the first device on the incoming
telephone circuit to properly function.
