Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
						Normal Terminal Stopping Devices.
(1)
Normal terminal stopping device switches shall be directly operated by
						the movement of the car. Normal terminal stopping devices may use mechanically
						operated, magnetically operated, optical, or static type
						switches.
(2)
Upper and lower normal terminal stopping devices shall be provided and
						arranged to slow down and stop the car automatically, at or near the top and
						bottom terminal landings, with any load up to and including rated load in the
						car and from any speed attained in normal operation. Such devices shall
						function independently of the operation of the final terminal stopping device.
						The device shall be so designed and installed that it will continue to function
						until the final terminal stopping device operates.
(3)
Directional stopping switches for
						normal terminal stopping devices shall be of the enclosed type located on the
						car or in the hoistway, and shall be operated by the movement of the car using
						metal operating cams.
EXCEPTIONS:
1.
						Elevators installed before June 5, 1947, that are equipped with an acceptable
						stopping device in the overhead or machine room positively driven from the car
						by a tape, rope, chain, or wire.
2.
						Winding-drum machines installed before June 5, 1947, having this device located
						on the machine.
(A) Where the stopping switch
						in the hoistway is arranged to function only in case the automatic slowdown
						circuit fails, an additional directional stopping switch driven mechanically by
						the car complying with the requirements of Section
						3039(a)(2), shall
						be mounted either in the machine room or in the hoistway.
(B) Where the automatic floor stop device
						complies with Section
						3039(a)(3), it may
						be used as the normal terminal stopping device.
(4) On elevators arranged to automatically
						slow down at the terminal landings, the normal terminal stopping devices shall
						be arranged to stop the car within the limits of top and bottom runby in case
						the automatic slowdown fails to function.
(5) When the slowdown switches used with the
						normal terminal stopping device are located in the machine room, they shall
						conform to the following:
(A) They shall be
						operated by a device mechanically connected to and driven by the car. Friction
						or traction drives shall not be used.
(B) Tapes, chains, ropes, or similar devices
						used as the mechanical connection to the car shall be provided with an
						electrical contact which will cause the electric power to be removed from the
						elevator motor and brake if the mechanical connection fails.
(C) The slowdown switches used as part of the
						normal terminal stopping device may function as the automatic slowdown provided
						a stopping switch is mounted in the hoistway that will fulfill the requirements
						of Section 3039(a)(4).
(6)
The winding machines of all
						power-driven, drum-type elevators shall be equipped with an acceptable normal
						terminal stopping device.
