Installation
1 Determine the Header Bracket Location
To prevent possible SERIOUS INJURY or DEATH:
lHeader bracket MUST be RIGIDLY fastened to structural support on header wall or ceiling, otherwise door
might NOT reverse when required. DO NOT install header bracket over drywall.
lConcrete anchors MUST be used if mounting header bracket or 2x4 into masonry.
lNEVER try to loosen, move or adjust door, springs, cables, pulleys, brackets, or their hardware, ALL of
which are under EXTREME tension.
lALWAYS call a trained door systems technician if door binds, sticks, or is out of balance. An unbalanced
door might NOT reverse when required.
lDO NOT enable the Timer-to-Close functionality if operating either one-piece or swinging doors. To be
enabled ONLY when operating a sectional door.
Close the door and mark the inside vertical centerline of the door.
Extend the line onto the header wall above the door. You can fasten the header bracket within 4 feet (1.22 m) of the left
or right of the door center only if a torsion spring or center bearing plate is in the way; or you can attach it to the ceiling
when clearance is minimal. (It may be mounted on the wall upside down if necessary, to gain approximately 1/2" (1
cm). If you need to install the header bracket on a 2x4 (on wall or ceiling), use lag screws (not provided) to securely
fasten the 2x4 to structural supports.
Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on the header wall 2" (5
cm) above the high point. This height will provide travel clearance for the top edge of the door.
NOTE: If the total number of inches exceeds the height available in your building, use the maximum height possible, or
refer to page 11 for ceiling installation.

Install the Door Control
2 Wire the door control to the door operator
PRE-WIRED INSTALLATIONS: When wiring the door control to the door operator make sure you use the same
wires that are connected to the door control.
1. Run the white and red/white wire from the door control to the door operator. Attach the wire to the wall and
ceiling with staples (not applicable for gang box or pre-wired installations). Do not pierce the wire with the
staple as this may cause a short or an open circuit.
2. Strip 7/16 inch (11 mm) of insulation from the end of the wire near the door operator.
3. Connect the wire to the red and white terminals on the door operator. To insert or release wires from the
terminal, push in the tab with screwdriver tip.

Introduction
Be sure power is NOT connected to the door operator BEFORE installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from closing door:
lCorrectly connect and align the safety reversing sensor. This required safety device MUST NOT be
disabled.
lInstall the safety reversing sensor so beam is NO HIGHER than 6" (15 cm) above floor.
IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORS
The safety reversing sensors must be connected and aligned correctly before the door will move in the
down direction.
The sending sensor (with an amber LED) transmits an invisible light beam to the receiving sensor (with a green
LED). If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to the full open
position, and the door operator lights will flash 10 times.
NOTE: For energy efficiency the door operator will enter sleep mode when the door is fully closed. The sleep mode
shuts the door operator down until activated. The sleep mode is sequenced with the door operator light bulb; as the
light bulb turns off the sensor LEDs will turn off and whenever the door operator lights turn on the sensor LEDs will
light. The door operator will not go into the sleep mode until the door operator has completed 5 cycles upon power up.
When installing the safety reversing sensors check the following:
lSensors are installed inside the building, one on either side of the door.
lSensors are facing each other with the lenses aligned and the receiving sensor lens does not receive direct
sunlight.
lSensors are no more than 6 inches (15 cm) above the floor and the light beam is unobstructed.

The following instructions show recommended assembly of the bracket(s) and “C” wrap based on the wall installation
of the safety reversing sensors on each side of the door or on the door tracks themselves. There are also alternate
mounting methods which may fit your installation requirements better. Make sure the wraps and brackets are
aligned so the safety reversing sensors will face each other across the door. Mount sensors no more than
6" (15 cm) above the floor and at a width between 7'-30' (2.1 m - 9.1 m).
Fasten the “C” wraps to the mounting brackets having square holes, using hardware shown.
