Abstract (en)
Elevator door air cord monitoring systems and methods are provided. The elevator door air cord monitoring systems include a door air cord (702) having a first end (706) and a second end (708) and an air cord monitoring system (714) connected to the door air cord (702). The air cord monitoring system (714) includes a power source electrically coupled to the door air cord (702) and configured to transmit a current through the door air cord and a controller arranged to monitor a resistivity signal associated with the current passed through the door air cord (702), wherein the controller is configured to generate a first maintenance signal if the monitored resistivity signal exceeds a threshold value.
