"ELECTRONIC

DOORS"

for elevators

Hong Kong

In 1950 we announced, "This is the electronic zone of detection on the new Otis Electronic Elevator Door. As illustrated below in color, this zone extends in front of the leading edges of both hoistway and elevator car doors from floor to shoulder height. When a passenger enters this zone of detection, it electronically "senses" the passenger's presence and energizes the relays that control door operation. The result? The doors politely and obediently reverse before they con touch the passenger. This zone travels with the car and provides double-door protection at each floor.”

TRAFFIC SPEEDING

DOORS

THAT CAN'T BE MATCHED

for high speed

operatorless elevators

As in 1950, it still doesn't make good sense in 1960 to equip high speed operatorless elevators with hoistway and elevator car doors that fail to make passengers step livelier when entering or leaving a car.

Seconds saved at each elevator stop can add up to hours of faster service in a busy building.

That's why Otis Electronic Elevator Doors are designed to encourage people to step livelier and speed traffic with the greatest degree of safety.

Otis Electronic Elevator Doors, with their electronic proximity zone of detection, need stay open at floor calls only long enough to permit a single passenger to leave or enter a car. Then they start closing. This alerts other passengers to step lively. However, as long as the electronic proximity zone of detection senses the presence of other passengers in the doorway, both hoistway and elevator car doors keep revers- ing with unequalled electronic politeness without touching the passengers. Then they start closing again. And the instant the last passenger has entered or left the car the doors close -and the car speeds away!

This unmatched traffic speeding, obtainable only with com- pletely automatic AUTOTRONIC® elevators, is available at only slightly higher cost than such standard equipment as rubber-edged contact doors and photo-electric devices.
