The swing-up mullion must be raised and lowered by a wire rope hoist with a secondary back-up wire rope arresting system. If the secondary back-up wire rope arresting system is fully integrated into the hoist unit, it must be produced by one manufacturer. Wire rope hoist and secondary system must connect to mullion a minimum of 10 feet above finish floor. Refer to the Section entitled, "Electrical Operation" for controls and interlocks of mullion and door panels.

Refer to the Section entitled, "Limit Switches" for information on mullion pin and floor strike limit switches. 2.8 OPERATION

2.8.1 Door Operation

The vertical lift fabric door must guide up and down in the weather sealed vertical guides attached to the structure. The door must operate by lifting the bottom beam upwards, thereby stacking the intermediate beams one on top of the other, with the fabric panel folding in pleats. The fabric panel must go over the top beam, covering both sides of the door, and must be attached to the intermediate beams by screws and batten strips. When the door is fully closed, the intermediate beams must hang between the two fabric door panels thus pulling the fabric tight. The tension created in the fabric panels must stabilize the intermediate beams. The safety arresters must be attached to each end of the bottom beam and must travel in the vertical guide tracks. The safety arresters must immediately stop the downward movement of the door in case of belt/cable failure.

2.8.2 Electrical Operation

Provide the main control panel with control logic such that when the integral female pin and sleeve emergency power receptacle is inserted and the integral manual transfer switch associated with the pin and sleeve receptacle is engaged the control panel will automatically limit only one door lift motor or one mullion lift motor to operate at a time.

When the door is completely opened it must stop on the primary top limit switch. In case of over travel, a secondary limit switch must stop the door to prevent damage. The drive unit must be stopped by the slack belt/cable breakers when the door is closed. The slack breakers must also stop the door in case of belt/cable rupture or if an obstruction should

SECTION 08 34 16.20 Page 17 prevent the door from being closed. Weight or springs must activate the slack breakers. The control panel station(s) must be of the illuminated pushbutton type or touchscreen.

Door operation must be controlled by three buttons marked "OPEN", "CLOSE", and "STOP". The "OPEN" and "STOP" buttons must require only momentary pressure to operate. The "CLOSE" button must require constant pressure to maintain the closing motion of the door. When the door is in motion and the "STOP" button is pressed or the "CLOSE" button is released, the door must stop instantly and remain in the stop position; from the stop position, the door must be operated in either direction by the "OPEN" or "CLOSE" buttons. Removing the pressure from the "CLOSE" button must stop the motor drive and set the brake.

Two buttons marked "Horizontal Position and Vertical Position" must control the mullion operation. Both buttons must be controlled by constant pressure to open and to close. Removing the pressure from either button must stop the motor drive and set the brake. The electrical control panel must provide an interlock function to coordinate door leaf and mullion operation.

Pushbuttons must be illuminated by LEDs and utilize simple flashing/solid illumination schemes to inform the operator of door status (fully open, closed, in motion, etc.). In lieu of illuminated pushbuttons, a large touchscreen display must be provided to select desired door leaf/mullion to operate and inform user of current door status. Pushbuttons must be full-guarded to prevent accidental operation.

Multipart doors must utilize a human machine interface display (HMI) for door leaf/mullion operation. Upon selection, door operation must be controlled by three buttons marked UP, DOWN, and STOP. The UP and STOP buttons must operate as indicated in the door operation controls section above.

When operating a mullion, controls must operate as described in the mullion operation controls above.

The main control panel must be equipped with backup method of controlling the door system should an HMI failure occur.
