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

ASME A17.1ASME A17.1

Safety Code for Elevators and EscalatorsSafety Code for Elevators and Escalators

Provides requirements for operationalProvides requirements for operational

sequences for:sequences for:

- Phase 1 - Emergency Recall Operation

- Power Shutdown - Shunt Trip Operation


4/96


Phase IPhase I--Emergency Recall OperationEmergency Recall Operation

The operation of an elevator wherein it is

automatically or manually recalled to aspecific landing and removed from normal

service because of activation of

firefighters service


5/96


Pow er Shutdown (shunt trip)Pow er Shutdown (shunt trip)

Mainline elevator power is disconnected

from the elevator to eliminate potentialproblems as a result of sprinkler actuation

in the hoistway or elevator machine room

Elevator Recall:Elevator Recall: Historical PerspectiveHistorical Perspective

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

Purpose:

Prevent people from using elevators

Responding Firefighters Account for Elevators

Stage Equipment (Hose lines, air tanks, etc.)

Evacuate Occupants with Mobility Restrictions

Prevent Car from being called to the Fire Floor


7/96

Identified Designated 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



8/96

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, Installation, Maintenance and use of

Local Protective Signaling Systems Elevator Recall

for Firefighters Service



9/96

Two elevator zone circuits were required to be

terminated at the associated elevator controller

In 1989, A17.1 required smoke detectors in hoistways

only when hoistways had sprinklers

First detector actuated determines the recall floor

A17.1b, 1992 Supplement drops the 25 ft. criterion now applies to all automatic elevators regardless of

travel distance



10/96

1993 edition of NFPA 72, National Fire Alarm Code

addressed cases where there was no required building fire

alarm system Elevator Recall and Supervisory Panel

1996 edition of NFPA 72 introduced other fire

detection as being permissible if environment was not

appropriate for a smoke detector.



11/96

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 Canadian

B44 Elevator Safety Standard

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

new technology elevators machine room-less

elevators



12/96

Shunt Trip:Shunt Trip: (Historical Perspective)(Historical Perspective)

First introduced in ASME A17.1 - 1984

Purpose:

Remove Main-line Power prior to sprinkler activation

Prevent Elevator from Moving/Operating dangerously

Note:the requirement does not include circuits for ventilation,

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