Elevator Door Lock Monitoring

At Capital Elevator Company, we provide Door Lock Monitoring (DLM) upgrades to ensure your elevators meet the latest ASME A17.3-2015 safety code requirements. Door Lock Monitoring enhances passenger safety by preventing unintended movement and door malfunctions, reducing liability risks for building owners. Serving Palm Beach, Broward, and Dade Counties, we help property managers and businesses achieve full compliance with Florida’s elevator safety regulations.

​

What is Door Lock Monitoring (DLM)?

ASME 17.3-2015 Section 3.10.12 introduced new safety requirements for automatic passenger and freight elevators, mandating that all systems include a door lock monitoring system. This system prevents elevator movement if the doors are not properly secured, reducing the risk of accidents caused by:

​

  • Faulty or worn-out door interlocks

  • Improperly closed doors

  • Electrical malfunctions in door circuits

  • Mechanical failures in locking mechanisms

​

Why is DLM Compliance Important?

  • Enhances Passenger Safety – Prevents elevators from moving when doors are improperly secured

  • Reduces Liability – Protects building owners and managers from potential legal claims related to door failures

  • Ensures Code Compliance – Meets ASME A17.3-2015 and Florida state regulations

  • Prevents Costly Repairs – Early fault detection helps reduce long-term maintenance costs

  • Avoids Inspection Violations – Helps pass mandatory elevator inspections without delays or penalties
