Telephone Connections
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 be located as the first device on the incoming telephone circuit to properly function.
