Elevator Recall (Phase I Operation) - Otis Elevator

This is an Otis elevator being shown in Phase I (fire service recall) mode. Elevator recall is activated by the elevator lobby smoke detector, which I trigger using canned "smoke". The red firehat indicator inside the elevator cab shows the elevator has gone into fire recall mode, and will return nonstop to the ground floor and become out of service. Elevator recall is operated and reset on Otis elevators with a UTF key. The black keyswitch I use in the beginning is the independent service, to hold the elevator at that floor while I trigger the recall.

Very interesting. Does any one know what model of key is used for a Otis 2000H elevator. I presume it is one of these

Model OTK-UTA Otis UTA

Model OTK-UTC Otis UTC

Model OTK-UTD Otis UTD

Model OTK-UTG Otis UTG

Thanks

The keys are common to Otis elevators, different keys are for different things.  I know UTF is universally a fire service key. UTA operates the ind. serv. UTE operates the stop/run, I also have a UTB and a UTG I think, they're probably for inspection mode or something.

UTC will work for ind svc to access locked out floors

@asimoko UTC is for keyed hall station cut-out switches

@paul9511 Sprinklers are set off by heat.
