What is an RJ31X jack and why should I have one installed?

An RJ31X Jack is a special inter-connective device that is installed at your premises on the telephone line that your alarm system is going to dial out on. Your security system control panel is designed to plug into this jack.

The RJ31X Jack provides a means for unplugging, and thereby disconnecting, your security system from the telephone lines.  This is done only in the event of a major security system malfunction, which prevents or interferes with the normal use of your telephone and must be reconnected after the problem has been solved.

The telephone company or your alarm dealer can install the RJ31X Jack.
