The New York City Department of Buildings has announced that, by January 1, 2020, all automatic passenger, service and freight elevators must provide a system to monitor and prevent automatic operation with faulty door contact circuits. All controller modifications performed to meet this mandate will require an Elevator Application under an EBN (Elevator Buildings Notice) and all modifications must be approved by a Registered Professional Engineer, Registered Architect and the controller manufacturer. The requirement is to prevent the elevator from operating under any circumstance with the hoistway or cab doors open; this is to eliminate the possibility of passengers becoming entrapped between the doors and injured if the elevator moves away from the landing floor. Passenger or service elevators with manually operated doors and gates are by definition exempt.

Depending on the age of the elevator, the equipment may require modifications to the existing controller system or upgrade/replacement. Controllers meeting the A17.1-2000 Code almost certainly have the door lock monitoring provisions built in, but, depending on the controller manufacturer, it is best to check to make absolutely sure. Most probably controllers that were installed prior to having met 1996 requirements, or microprocessor controlled systems older than 18 years, will need a full modernization of the equipment. Owners of buildings with relatively recent elevator installations may be able to comply with this code requirement simply by adding certain software/hardware to the existing relay logic/microprocessor controller; in most cases, the microprocessor and relay controllers will require the addition and wiring in of a panel with solid state boards and relays.

After January 1, 2020, non-compliant systems may be subject to violations, clearly a situation to avoid. It is best to start planning now or at the least very soon, since, in the case of multiple elevators, it could take up to two years or more to specify, complete and obtain approval of a full modernization. In no case should this work be scheduled later than in 2018, especially since there will be widespread demand for this service, and more limited ability to provide it, as the 2020 deadline approaches.

The experts at D&D Elevator stand ready to help you to evaluate your particular needs, sort smoothly through the complexities of this code requirement – achieve safety and code-compliance – and boost your peace-of-mind!

Stuck In An Elevator? Do It Right: Sit Tight!

By: D&D Elevator

stuck in elevatorWhen people are riding an elevator, and it lurches to a stop between floors, often the initial gut response is to panic – especially among those who are claustrophobic – and what to do to most quickly to get out. Publicly-available accounts and data show that escape attempts can result in severe injury, sometimes fatal; for example, during a recent year, New York City’s Department of Buildings reported that 51 people were injured and five died when trapped riders tried to save themselves.

Municipal governments are undertaking campaigns to educate the riding public to the proper procedures during entrapment, such as New York City’s “Stay Safe - Stay Put” public awareness campaign – using broadcast ads, print ads, bus shelter messages and a public service video – to encourage riders to remain in stalled cars and wait for help,

As a service to building owners and managers, and other D&D Elevator Maintenance customers, D&D has prepared a comprehensive Safety Guide for Entrapped Passengers, which may be viewed online here and printed as a hard copy for provision to superintendents, co-op/condo boards, etc., for their review and appropriate distribution to tenants.
