Agenda:

Elevator Recall and Power Shut-down

Historical Perspective

Where we are today, code-wise

Look at specific code sections

Discuss some of the issues

Where we appear to be headed


3/113

ASME A17.1

P hase I - Em ergency Reca l l Ope ra t ion

The operation of an elevator wherein it is automatically

or manually recalled to a specific landing and removed

from normal service because of activation of firefighters

service


4/113

ASME A17.1

Pow e r Shu t dow n ( shun t tr ip )

Mainline elevator power is disconnected from the elevator

to eliminate potential problems as a result of sprinkler

actuation in the hoistway or elevator machine room


5/113

Elevator Recall: Historical Perspective

1973 ASME A17.1b(supplement to the 1971 Code)

Purpose:

Prevent people from using elevators

Allow firefighters to account for elevators

Stage equipment (hose lines, air tanks, etc.)

Evacuate occupants with mobility restrictions

Prevent cars from being called to the fire floor


6/113


7/113

Identified a Recall Level

Both Manual and Automatic Recall

Key Switch (only by firefighters)Smoke Detectors in Lobbies

Travel of 25 above or below designated level

1981 introduced the Alternate Level



8/113

1984 introduced only lobby and machine room

detectors were to initiate recall

A17.1 referred users to NFPA 72E, Automatic Fire

Detectors

NFPA first mentions A17.1 requirements in 1987 edition of

NFPA 72A, under Elevator Recall for Firefighters Service



9/113

Two elevator zone circuits now required to be

terminated at the associated elevator controller

In 1989, A17.1 required smoke detectors in hoistways

only when hoistways had sprinklers

A17.1b, 1992 Supplement drops the 25 ft. criterion

now applies to a l l automatic elevators regardless of

travel distance



10/113

A third control circuit was added to provide a warning

of fire in the hoistway or elevator machine room

The 2000 A17.1 was harmonized with the CanadianB44 Elevator Safety Standard

NFPA 72 [2002] and A17.1 [2004] now both address

new technology elevators machine room-less

elevators



11/113

Elevator Shunt Trip: Historical Perspective

First introduced in ASME A17.1 - 1984

Purpose:

Remove main-line power prior to sprinkler activation

Prevent elevators from moving/operating dangerously

No t e :

the requirement

does not include circuits for ventilation,

in-car lights and communication, pit receptacles and lights, etc.


12/113

A17.1 applies to all new elevator installations

A17.3 (where adopted) applies to existing elevators

A17.3 re: Firefighters Service

3.11 .3 F i re f igh te rs Se rv i ce

Elevators shall conform to the requirements of

ASME/ANSI A17.11987 Rules 211.3 through 211.8

(see Appendix C) unless at the time of installation or

alteration it was required to comply with a later edition of

A17.1.

and for protection of fire alarm control units. In high ceiling

areas, to achieve the desired initiation such as for elevator recall
