DMP 893A Dual Phone Line Module

The DMP 893A Dual Phone Line Module is a robust and reliable solution for your communication needs. This module supervises both the main and backup phone lines, alerting users of any sustained drop in voltage through a built-in sounder and indications at the keypad and monitoring center. It installs seamlessly in a panel enclosure and connects to the panel through a wire harness and phone cord. The DMP 893A is designed to indicate a phone line failure to the premises and central station, and it automatically switches to secondary phone line communication when the primary line is down. Any phone line trouble is conveniently displayed in the keypad Status List as a System Trouble.
