Two independent telephone lines can be connected to the control panel. Telephone line con-
trol/command is made possible via double line seizure as well as usage of an RJ31X style intercon-
nection. 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 per require-
ments of UL 864 9th Edition.
