that reads "Medical Emergency." All car calls shall be canceled and be unable

return to automatic operation after a minimum of 15 seconds and a maximum delay
of 60 seconds and then proceed to the main floor.

a car call until the in car EMS key switch is turned to the on position. After
turning that key on and registering a call, the car shall automatically close
its doors and proceed to the call. All door zone detection devices shall be
operative. If more than one call is registered, it shall stop at the first call
and cancel all others at which time a second choice can be made.
(b) Upon arriving at the desired floor, the
doors shall open automatically and the EMT shall remove his key when the switch
is in the off position, the car shall then remain at that floor and will not
accept a call or move away from that floor until the key is again turned
on.
(c) The car shall be returned
