which are in normal service shall return non-stop to the floor
where the swi.tch is in the "on" position and the doors shall
open, except that an elevator traveling away from the main

main floor may be initiated by heat and/or smoke sensing
devices. in the building independently of the switch required
by Provision 1, above, except that such devices at the main
floor shall not initiate the return of the elevators. If
so, the switch required at a main floor shall have three (3)

be provided in or adjacent to an operating panel of each
elevator car. This switch, when operated, shall put the
elevator on emergency service and shall be operable only
after the switch required by Provision 1,- above, has been
activated. When the emergency se:r'Vice switch in the elevator
is actuated:

1478
(ii) Elevators on emergency service shall not respond
to elevator landing calls.

for the switches required by Provisions 1 and 3,. above, shall
be kept on the premises by the person responsible fb.r. the
maintenance and operation of the elevators, in a locat~on
readily accessible to authorized persons in an emergency,
but not where they are available to the public.
(b) Attendant Operated Elevators. Elevators operated
only by a designated operator in the car shall be proviged with
signal system to permit signalling the operator from the main floor
