    How to Use K5 Trouble Relay on the 2071 DACT Family

    Issue

    How does the trouble relay K5 work?

    Solution

    Phone Line Trouble Relay (K5)

    Install a D136 Relay in the Phone Line Trouble Relay K5 socket (Item 10 in Figure 1) when using the optional Phone Line Trouble Relay (Terminals 13 to 15). This relay activates when a telephone line trouble is detected on either the primary or secondary telephone line, when there is a communication failure, and briefly on power up.
