5. A stop switch (emergency stop) is required in each elevator pit at the access door to the pit.

If the pit exceeds 6 ft, 7 in., a second switch is required adjacent to the ladder. The two switches

will be connected in series. See ANSI/ASME A17.1, Section 210.

6. Car lighting shall consist of a minimum of two lamps to be supplied by a dedicated circuit with

a lock-open disconnect in the equipment room.

7. A 115-V, 20-A receptacle shall be provided in all equipment spaces and in the pit.

8. A phase-reversal protection shall be provided to ensure that the elevator motor cannot start

if the phase rotation is in the wrong direction or if there is a failure of any phase.

9. Capacitors and other devices whose failure could cause unsafe elevator operation are

prohibited; only devices specified by the NEC or the manufacturer may be installed.

6.3.5 FIRE PROTECTION

The electrical designer shall coordinate with the manufacturer the design of the fire protection

systems that connect to the elevator control panel. The system will be designed to return the car to

a designated area (normally the first floor or lobby) in the event of smoke or fire in the equipment

area or near the elevators. In that event, the car returns to a designated area where passengers can

safely exit the facility. In addition to coordinating car control, the system provides for the shutdown

of the electrical elevator equipment prior to operation of the sprinklers and the transmission of the

alarm and provides a means for the firefighters to assume manual control of the elevator from the

designated area. The requirements for these systems are detailed in ANSI/ASME A17.1, Section

211, "Emergency Operation and Signaling Devices."

6.3.6 INSPECTIONS AND RECORDS

Elevator inspections and recordkeeping are performed in accordance with the local authority having

jurisdiction. The ANSI/ASME A17.2 series of inspectors manuals provide a guide for performing

tests and inspections as well as recommended inspection checklists. In addition to acceptance

inspections and tests, the code requires 1-and 5-year inspections for electric elevators and 1-and 3-

year inspections for hydraulic elevators.

6.3.6.1 CODES

Elevators are required to be in compliance with the issue of ANSI/ASME A17.1 in force the date they

were installed. If the local authority has adopted ANSI/ASME A17.3, the code for existing

installations, they shall be in compliance with it, except they shall not be downgraded to it. When

ANSI/ASME A17.3 is in force, it becomes the minimum standard to which installations shall adhere,

and if existing installations are upgraded in accordance with ANSI/ASME A17.1, Part XII, they shall

also be in compliance with the more stringent requirements of A17.3.
