The RJ-31x connector type is used to connect a security system control panel to a telephone interface.
Key Takeaway: RJ-31x jacks are designed to provide a fire or security alarm panel preference in dialing out in case of emergency. If any other terminal device, like a phone or a fax, is using the line when the alarm panel needs to call, the panel'' internal circuitry breaks that connection and establishes its own connection.
