What is the phone jack required to disconnect the DACT from the telephone service called?

The phone jack required to disconnect the Digital Alarm Communicator Transmitter (DACT) from the telephone service is called an RJ31X. This specific type of jack provides the necessary connection for security systems to interface with traditional telephone lines. It allows for easy installation and disconnection, which is particularly important in alarm systems where the ability to quickly sever the connection in case of an emergency or maintenance is crucial.

The RJ31X configuration is designed to accommodate the needs of alarm systems by enabling the DACT to seize the phone line for outgoing signals while still allowing regular phone service to function normally. This feature is particularly advantageous in alarm systems, making it a preferred choice for professionals installing security devices.

In contrast, RJ45 jacks are primarily used for Ethernet connections in network settings, while RJ11 jacks are standard for conventional telephone connections without the added specifications for security systems. RJ12 is similar to RJ11 but with additional wires, making it more suitable for specialized telephone equipment rather than alarm systems. Understanding these distinctions can help ensure the correct components are selected for security installations.
