HYDRAULIC PASSENGER ELEVATOR 14 24 00 - 12

1. Door operation shall be automatic at each landing with door opening being initiated as the car arrives at the landing and closing taking place after expiration of a time interval. A car door electric contact shall prevent starting the elevator away from the landing unless the car door is in the closed position.

Door close shall be arranged to start within a time consistent with accessibility requirements.

2. The time interval for which the elevator doors remain open when a car stops at a landing shall be independently adjustable for response to car calls and response to hall calls.

B. Interlocks & Closers: A new approved positive interlock shall be provided for each hoistway entrance which shall be made to work in conjunction with the new door operators. The interlocks shall prevent operation of the elevator unless all doors for that elevator are closed and shall maintain the doors in their closed position while the elevator is away from the landing.

1. New closers shall be provided The closers shall be adjusted to automatically close the hoistway doors when the car is away from the landing per Elevator Code requirements.

C. Car Door Safety Devices: The existing door safety devices shall be removed and discarded. New infrared, door protection devices shall be installed and made to work in conjunction with the new control equipment. Operation for all devices to be as follows:

1. The doors shall be prevented from closing from their full open position if a person or object comes within the zone of detection. The detection zone shall move with the doors and if a person or object enters the zone as the doors are closing, the doors shall reverse and reopen prior to physical contact.

The doors shall reclose after a minimal time interval. After a stop is made, the doors shall remain open for a time interval to permit passenger transfer, after which the doors shall close automatically.

This interval shall be less for a car call stop than for a hall call stop or a coincident car/hall call stop.

2. If the doors are prevented from closing for a fixed time period an audible chime shall sound on the car. When the object is removed from the zone of detection the doors shall close at reduced power and speed to below 2 1/2 ft.-lbs. of kinetic energy. If an object enters the zone of detection while the doors are closing at reduced power and speed the doors shall stall and not reopen. Once the object is removed from the zone of detection the doors will continue to close at reduced power and speed.

This operation will continue until the doors are totally closed. Normal operation shall resume at the next landing reached by the car.

3. The doors shall reopen should detection of an object approaching the landing side doors be detected as stipulated in Elevator Code. This detection means shall operate regardless of lobby floor finish and cross traffic in front of the elevator entrances shall not activate the door reopening. No parts shall intrude into the clear opening width or height. Provide Formula Systems Vision Plus model
