D. Position Selection: The position selection is a integrated part of the microprocessor

based control system. The car position in the hoistway is digitized through a steel tape running the full length of the hoistway encoded by the car position transducer. The car position transducer detects magnetic leveling strips installed on the tape for floor reference and stopping accuracy. The microprocessor based control system will store the floor position and slowdown points in memory.

E. Performance: Adjust elevators to meet the following performance requirements: 1. Running Speed: +/- 5 percent of contract speed under all load conditions. 2. Floor to Floor Performance: 11 seconds between typical floors. Time is

ELEVATOR EMERGENCY OPERATION AND EMERGENCY SIGNAL DEVICES PART 1 GENERAL 1.01 SYSTEM DESCRIPTION A. The elevator emergency operation and emergency signal devices enable elevators

to be operated under fire or other emergency condition. B. Passengers in elevator cars may communicate with the Safety Office via a hands

free auto-dialer telephone system. C. Phase I - Firefighters Emergency Operation: A three position (reset, off, on) key

operated switch at the designated floor (first floor) enables elevators controlled by the switch to be secured under fire or other emergency conditions:

1. Operation of Phase I Firefighters Emergency Operation shall be in accordance with ASME A17.1 Code.

D. Phase II - Emergency In-Car Operation: A three position (off, hold, on) key

operated switch in or adjacent to each car operating panel becomes effective only when the Phase I switch has been turned to the “on” position or a smoke detector has been activated.

1. Operation of Phase II - Emergency In-Car Operation shall be in accordance with ASME A17.1 Code.

E. Failure of a.c. operating power to normal elevator lighting fixtures automatically

causes a existing battery powered emergency light to illuminate. F. Failure of a.c. operating power to alarm bell automatically causes bell to operate

from battery source when emergency call button is pushed. G. Upon failure of normal electric service to the elevators, an emergency electric

service (standby generator) powers the elevators on a limited, priority basis. Sequence of operation:

1. Upon transfer to emergency power the elevator dispatch controller receives a signal from the automatic transfer switch and activates the emergency dispatching function; One elevator at a time will be dispatched automatically, sequentially to the designated floor lobby. Upon completion of the automatic sequential dispatching, Elevators No. 1 shall remain on emergency power operation. A manual strip switch at the lobby dispatch panel allows a building attendant to override the automatic sequential operation. If the automatic dispatching function was overridden via the manual selector switch in the designated floor dispatch panel the manual station must be reset to the automatic position and the elevators will revert to the automatic sequential dispatch mode.

2. A manual strip switch at the designated lobby allows a building attendant


to manually select an elevator other than the automatically selected elevator to operate during the emergency stand-by power duration. Prior to restoration of normal power the automatic transfer switch sends a pre-signal to the elevator dispatch controller(s) indicating normal power transfer is about to take place. Elevators under emergency power operation then park at the nearest floor and await transfer to normal power. The elevators then revert to normal operation. If the automatic dispatching function was overridden via the manual selector switch the manual station must be reset to the automatic position for the elevators to revert to normal operation mode.
