ARCHITECTURAL SPECIFICATIONS (DRAWBAR):

Electric door operator(s) shall be Solid State Control Model GT of the gearhead trolley (drawbar) type, manufactured by
Linear LLC and Underwriters Laboratory (UL) listed. Horsepower, voltage and phase will be as required to properly operate
the door. Operators will be equipped with speed reduction (enclosed gear reducer having worm and worm gear running in oil
bath). The operator will have a double angle (nominal 11 gage, 2” X 2”) trolley track of sufficient length to accommodate the
height of the installed door. The trolley will be driven with roller chain. The door arm will be provided with a trolley
disconnect for manual door operation. The operator will be equipped with an integral limit system that provides accurate
settings to control the open and close positions of the door and will not be affected by manual door operation or motor
removal. The motor and operator will be protected against overload by a thermal protector. The operator will have a 24VAC
secondary solid state control circuit with advanced switch selectable features, motor load delivered via high amperage, inductive load rated
relays. The operator will have provisions for connecting open-close-stop pushbutton stations, radio controls, and external obstruction sensing
(reversing) systems. The door speed will be approximately 11-12 inches per second.
