Door Lock Monitoring

A Door Lock Monitor (DLM) is an essential device installed on most elevator controllers. It ensures the elevator does not leave the floor with open doors, safeguarding against accidentally or intentionally bypassed door circuits. By preventing automatic operation when door contact circuits are faulty, it plays a crucial role in elevator safety. A17.3* code requires that all existing elevators have an additional cab door monitoring system and logic. A17.3* code for existing elevators implements safety enhancements retroactively. 

When you choose our Cab Door Monitoring solution, you receive a comprehensive package that includes a new logic system, boards, sensors, power supply, and a NEMA 1 cabinet. Plus, we provide updated software and logic to ensure your elevator operates smoothly and efficiently.
