Electricity is often one of the initial services to fail during a storm. The ASME A18.1-2017 is the Safety Standard for Platform Lifts and Stairway Chairlifts. Learn your best options for addressing this with your emergency phones. Chapter 30 Elevators and Conveying Systems. . Traveling cables are to be supported by one of these means: Looping the cables around supports for unsupported lengths less than 100 ft. Each fused switch or circuit breaker in the panelboard is used as an elevator disconnect. Elevator Electrical Requirements By General Contractor/Owner Each residential elevator requires three (3) items from your electrician and telecommunications contractor(s). First, the ATS signals the elevators that it's about to switch over to emergency power preferably 30 sec or more prior to switching, which allows the elevator controller to bring each elevator cab to the nearest landing and stop, thus protecting the motors and electrical system.

FmQ0TIc RTcmkwbm0D Q,%^) GET YOUR CEUS TODAY, 1998-2021. Requirements in Article 620 modify the articles in Chapter 3. The California Building Code (CBC) contains general building design and construction requirements relating to fire and life safety, structural safety, and access compliance. 21. This means that the majority of hydraulic type elevators will require this and traction type elevators need it only where the construction of the shaft is of combustible or limited-combustible material. endobj Fireman telephone jacks and telephone cabling are typically sufficient for each of these locations. And as the designer, you can become the fulcrum on which all of these requirements and authorities exert their leverage, but an understanding of elevator basics can help you handle the pressure. \ A&&'70 Sk*EZfm}1csX)9R5R8jW5J)+5s!?>)%Xv}/)_x>j@WCw[ 4 0 obj While the provisions highlighted here from NFPA 13 are relatively straightforward there is added complexity of elevator codes as well as local amendments in many jurisdictions. Chapter 32 Encroachments Into the Public Way. Section 620.43, Location of and Protection for Cables, provides that traveling cable supports are to be located so as to reduce the possibility of damage due to the cables coming in contact with the hoistway construction or equipment in the hoistway to a minimum. Sprinklers are permitted to be omitted from the top of the shaft where the hoistway is noncombustible or limited-combustible and the car enclosure materials meet the requirements of ASME A17.1, Safety Code for Elevators and Escalators. All rights reserved. Many people use portable generators until power is restored. Join the thousands who receive our monthly emails with advice on safety & code compliance. The Safety Code for Existing Elevators and Escalators is the ASME A17.3-2015. Elevators with driving machines located on the car or counterweight, or in the hoistway are permitted outside the specified spaces. Convenience receptacles and lighting for maintenance purposes are required at the base of the pit and, in some instances (elevator manufacturer dependent), at the top of the elevator shaft.

The code does not include design specifications or instructions like those found in installation manuals. Note that sprinklers are shown in the pit and machine room of the hydraulic elevators as those are always required but the top of the hoistway for hydraulic elevators and the pit, top of hoistway, and machine room for traction elevators can also require sprinklers.

It is also essential that machine-room lighting be totally reliable and separate from the machinery supply to facilitate troubleshooting in the event of elevator problems. The Safety Code for Existing Elevators and Escalators is the ASME A17.3-2015. Such fast elevators could be built, but the New York City building code limited elevator speeds to just 700 fpm.
