DOOR
OPERATING
EQUIPMENT
Remove the existing car door operators, headers, tracks, clutch, and accessories. Clean, polish,
and retain the existing Stainless Steel Car Door Panel. Furnish and install new direct current
motor driven heavy-duty operator on all cars. The door operators shall be designed to operate
the car and hoistway doors simultaneously. Door movements shall be electrically cushioned at
both limits
of
travel. Doors shall automatically open when the car arrives at a landing and
shall automatically close after an adjustable time interval or when the car is dispatched to an-
other landing. The door operator shall
be
fully closed loop providing direct current feedback
and continuously monitor the position
of
the door throughout the door travel. The door opera-
tor shall be capable
of
applying more torque for heavy lobby doors and to handle varying
hoistway wind conditions.

signed to operate as described below:

During the "Open" cycle, the "Panachrome" electronic door detector shall illuminate
and flash Green. During the "Close" cycle, the "Panachrome" electronic door detector
shall illuminate and flash Red.
2.
After a stop is made, the doors shall remain open for an adjustable time interval. Clos-
ing may be initiated instantaneously by registration
of
a car call, operation
of
load
weighing device or signal from the service demand integrator.
3.
The doors will remain open as long as the electronic detector senses the presence
of
a
passenger or object in the door opening.
If
door movement is obstructed for a prede-
termined time, a buzzer will sound and the doors will close at reduced speed.
4.
If
a passenger
or
object is detected during normal closing operation, the doors will
immediately stop and reopen. Closing will be initiated one-half second after the pas-
senger or object has been removed from the opening.
5.
The doors shall remain open for an adjustable time for a stop in response to a car call
and a second variable time for a stop in response
to
a hall call.
If
the beams
of
the
electronic detector are interrupted and reestablished, door open time for a car stop and
for a hall stop shall be reduced.
