NABCO ENTRANCES, INC., S82 W18717 Gemini Drive, Muskego WI 53150, (877) 622-2694, (888) 679-3319 fax Rev 10/13
temperature conditions. Attached to transmission system shall be a DC permanent magnet motor with sealed ball
bearings. Motor shall operate from 115-volt supply and require less than 3 amps at full power stall. Complete unit
shall be resilient mounted with provisions to easily adjust/replace the motor and gearbox without removing door from
pivots or frame.
3) Electrical Control: Shall be a solid-state microprocessor unit. The microprocessor control shall allow the opening
speed, closing speed, back check and latch check speed each to be adjusted separately and independently from each other
to meet specific site conditions. Adjustable opening and closing speeds shall be set in accordance with ANSI A156.10.
All adjustments shall be specific and reproducible.
4) Connecting Hardware: Connect overhead (OHC)-type power operator drive arm to door with a pin linkage rotating in
a self lubricated bearing, within a self adjusting slide block, traveling in an interconnected steel track and top door pivot
assembly. The (OHC) unit will independently support the door on heavy-duty steel top and bottom door pivots. To allow
for durability and easy serviceability, the door shall not pivot on shaft of operator.
5) Emergency breakaway doorstop shall mount directly to the underside of operator housing. It shall function as a stop
on all center pivoted in-swinging doors. A force of not more than 50 LBF applied at the lock stile shall cause the
breakaway stop to rotate, interrupt automatic operation and allow the door to swing open 180 degrees opposite its normal
travel. Swinging the door back into the normal mode of operation resets the breakaway doorstop and reengages the
operator for normal automated operation.
2.03 ACTIVATING DEVICES
A. Sensor Devices - Approach side. Nabco Entrances Acusensor or Optex Reaction Two
1.) The Acusensor as manufactured by NABCO ENTRANCES, INC. is a presence sensing active infrared sensor.
Sensing shall be provided in a rectangular shaped pattern with sensing immediately next to the door system. To provide
optimum coverage to meet specific site conditions the sensing pattern width and depth shall be adjustable while
remaining at a full power setting.
2.) The OPTEX Reaction Two microwave sensor is specially designed to increase efficiency on opening of automatic
doors. Uni-directional mode ignores traffic moving away from the door and assures the minimum door open time. The
OPTEX microwave provides fast detection for automatic door installations and particularly for applications with high
speed entries
B. Sensor Devices - Swing Side. The Optex OA Edge system shall be provided which includes two sensors mounted near
the top of the door to provide continuous sensing coverage on both sides of the door panel including during the opening
and closing operations.
C. Additional Specification Options for consideration - See product catalog

A156.10, manufacturer’s recommendations and approved shop drawings.
3.01 CLEANING AND PROTECTION
A. After installation, clean framing members as recommended by the manufacturer. Aluminum surfaces in contact with
masonry, concrete or steel shall be protected from contact by use of neoprene gaskets, where indicated, or a coat of
bituminous paint to prevent galvanic or corrosive action. Advise general contractor to protect unit from damage during
subsequent construction activities.
* COVER NOTE TO SPECIFICATION WRITER
Indicate under appropriate Section the following work by others:
ELECTRICAL INSTALLER shall furnish and install all conduit and electrical wiring for activating devices and door
operators. A minimum of 5 amperes, 115 volts, A/C, 1-phase circuit shall be furnished for each door operator, terminate
and connect to operator control panel, in operator housing.
CONCRETE INSTALLER shall prepare floor at location of automatic entrance system to be level and smooth without
changes in elevation between foundation and associated walkways.
