Elevator Firefigher (Phase II) Operation - Otis Elevator

This is an Otis elevator being operated in Phase II firefighter's mode after elevator recall was activated with an elevator lobby smoke detector. Phase II operation is used with the fire service keyswitch inside the elevator car, and can only be used after elevator recall is activated with a smoke detector or the ground floor fire service switch. Phase II is very similar to independent service.

Note how the Door Open and Door Close buttons must be manually pushed in AND held for the doors to operate. This is a safety feature to firefighters, so that if the door is opened and fire or other dangerous conditions enter the elevator, the button can be released and the doors close immediately.

which key did u used?

UTF or UTE

[blackmaxima]

UTF is for fire service, I think UTE is the stop/run switch key.

It is almost exactly like independent mode except that in independent mode, the doors open automatically when it reaches a floor. Also in phase 2, all door reopening devices are inoperative including the safety edge.

I thought that in the Dover/TK classic elevators with the square buttons, the car would stop in independent service, but you had to control the doors with the door open and door close buttons.

BTW, I see YouTube videos on how to put an elevator into independent service by pressing and holding the desired floor button and the door close button simultaneously for a few seconds. does anyone know if this actually works, and what elevators it will work on?

@carolyn19858 He used UTF

[theansulman]

@blackmaxima UTE is for car top inspection. UTA is used for Run/Stop, fan, lights, and Ind. Svc. UTD is for keyed hall call stations and express service. UTC is for Attendant service. And UTF is for fire service.

Yes, he is.

I have not come across one elevator when it worked. the best way to check and see is to go to a middle floor, press both up and down call buttons, then whichever direction gets called first go in that direction. then come back the other way to a floor below the original floor, if it doesn't stop at your original floor then it worked. The elevator trick doesn't put it into the same independent service; it just puts it in to skip mode. Skip mode only skips outside calls; inside calls arent skipped
