I have duplex Kone Miprom elevators and there are 2 issues. Also, the elevators were inactive for several years.
1) One of the elevators will not go to the 4th floor when the button is pressed. It will go to the 5th floor then to the 4th floor. It's like there is a latching relay issue but there are no latching relays. We've had the elevator running since April and we just started having issues with the 4th-floor call.
2) When a smoke detector is activated, only one elevator will go to the first floor and open the doors. The other elevator comes to the first floor then the doors close and the elevator will run. The elevator with the 4th-floor call issue is also the elevator that has issues with fire service when a smoke detector is activated. (The phase 1 and 2 key switches work on both elevators) The original smoke detectors were removed and a fire alarm company just installed new smoke detectors.
Any assistance is appreciated.
