beams one on top of the other, with the fabric panel folding in pleats.  The fabric panel shall go over the top 
beam, covering both sides of the door, and shall be attached to the intermediate beams by screws and batten strips.  
When the door is fully closed, the intermediate beams shall hang between the two fabric door panels thus pulling 
the fabric tight.  The tension created in the fabric panels shall stabilize the intermediate beams.  The safety 
arrestors shall be attached to each end of the bottom beam and shall travel in the vertical guide tracks.  The 
safety arrestors shall immediately stop the downward movement of the door in case of belt/cable failure.</TXT><BRK/>

<TXT>When the door is completely opened it shall stop on the primary top limit switch.  In case of over travel, a 
secondary limit switch shall cut off the drive units' motor current to prevent damage.  These two limit switches 
shall be activated by the uppermost intermediate beam.  The drive unit shall be stopped by the slack belt/cable 
breakers when the door is closed.  The slack breakers shall also stop the door in case of belt/cable rupture 
or if an obstruction should prevent the door from being closed.  Weight or springs shall activate the slack breakers.  
The control panel station(s) (remote push button station located at the opposite side of the hangar is optional) 
shall be of the pushbutton type.  Door operation shall be controlled by three buttons marked "OPEN", "CLOSE", 
and "STOP".  These buttons shall be controlled by momentary pressure to open and constant pressure to close.  
Removing the pressure from the "CLOSE" button shall stop the motor drive and set the brake.  Two buttons marked 
"Horizontal Position and Vertical Position" shall control the mullion operation.  Both buttons shall be controlled 
by constant pressure to open and to close.  Removing the pressure from either button shall stop the motor drive 
and set the brake.  The door manufacturer shall provide a NEMA enclosure that is factory-wired and equipped with 
instantaneous overload relays.  Emergency power hook up shall be provided at the control panel connecting the 
drive units to a portable emergency generator.  The Contractor shall demonstrate the operability of all limit 
switches prior to the Government accepting ownership.</TXT><BRK/>
