An exemplary method of managing remote control of an elevator system includes preventing any source located remotely from a site of the elevator system from controlling an operation of the elevator system when there is an indication that the elevator system is being serviced by a mechanic.

Managing remote control of an elevator system

A method for monitoring a manual elevator door system comprising the steps of: providing a plurality of sensor signals; detecting the sensor signals; determining in response to detecting the sensor signals that an elevator car is stopped at a landing; determining in response to detecting the sensor signals that a car door of the elevator car is open; determining in response to detecting the sensor signals that a hoistway door is unlocked; determining in response to detecting the sensor signals that a hoistway door is closed; determining in response to detecting the sensor signals that a call has been assigned to the elevator car during a time that the hoistway door is closed; and providing a performance data signal in response to said determinations wherein said performance data signal is representative that the manual elevator door system is in a non-alarm condition.
