Purpose. The purpose of ASME A17.1/CSA B44, Safety Code for Elevators and Escalators, is to provide for the safety of life and limb, and to promote the public welfare. Compliance with this Safety Code shall be achieved by:

(a) Conformance with the requirements in ASME A17.1/CSA B44; or
(b) Using alternative materials, equipment, or methods of construction and design approved in conformance with the requirements of Section 104.11, 12-A DCMR for systems, subsystems, components, or functions that do not conform with requirements in ASME A17.1/CSA B44.

The "ALARM" switch or visual identification shall illuminate when the "ALARM" switch is actuated. One audible signaling device shall be permitted to be used for a group of elevators. The audible signaling device shall:

(a) Have a rated sound pressure rating of not less than 80 dBA and no more than 90 dBA at 3 m (10 ft);
(b) Respond without delay after the switch has been activated;
(c) Be located inside the building and audible inside the car and outside the hoistway; and
(d) For elevators with a travel greater than 30 m (100 ft), be duplicated as follows:
(1) One device shall be mounted on the car; and
(2) A second device shall be placed at the designated level.

Strike Section 2.27.1.1.5 of ASME A17.1 and insert new Section 2.27.1.1.5 in its place to read as follows:

2.27.1.1.5

(d) "FIRE OPERATION" switch, unless otherwise specified in Section 3.27.
3.26.10.2

When the auxiliary lowering operation has been initiated, the car shall descend directly to the lowest landing, except that the operating system shall be permitted to allow one or more intermediate stops, and then, after a predetermined interval, the car shall proceed to the lowest landing, provided the auxiliary power supply is of sufficient capacity to open and close doors at each intermediate stop.

3.26.10.3

If the car and landing doors are power operated, and if the auxiliary power supply is of adequate capacity, the doors shall open when the car stops at the lowest landing a nd shall close after a predetermined interval.
