Low Voltage Wiring
There are two low voltage wiring circuits required for any new operator today:

The wallbutton station. The Wallbutton circuit runs from the ceiling, centered on the door opening, and
the operator outlet setback distance. Leave a minimum of 3' lead to connect to the operator. The other
end runs to whereever the wallbutton will be mounted. Please note that the wallbutton should be located
so that the door is in visible range and can be seen when activated. Also, it should be placed about 5' up from the floor.

The Safety/Photoelectric Sensors. There are two circuits, one for each side of the door. Leave a 24" lead,
6" off the floor, and 4 - 6" back or to the side, and both sides of the door opening. These leads come out of
the ceiling at the same location as the wire for the wallbutton with a minimum of 3' lead.

INSIDE WIRING & FRAMING FOR GARAGE DOOR INSTALLATION PREPARATION

CONCRETE STEM WALLS

There must be 3" OVER the actual door size in between any concrete stem wall on
either side of door. For example, a 16' wide door will require 16' 3" between the concrete,
a minimum of 1 1/2" on each side. We recommend placing an additional 2 x 6 block on each
side when pouring a new foundation. If there is less than the minimum 3", the concrete must
be cut back prior to installation, or casing must be built out flush to concrete.

EXAMPLE:

*NOTE - In this example, the opening size at this point will be approx. 16'. This example will
still require the "2 by" trimmers to bring the opening size to 15' 9". (See example below).

________________________________________

FRAMING OPENING

For best installation and door operation, frame for a clearance of 14" of ceiling height above
door opening. This allows for use of standard 12" radius track, and room for opener installation.
If possible, allow 17" of clearance for 15" radius track. This is required of some doors, primarily
steel & wood carriage house doors. If there is less than the desired clearance, special low
headroom track may be required. Please note, low headroom track may sacrifice getting the door
up past the opening completely. Contact us for clearance requirements for specific doors.

FRAMING EXAMPLE

When preparing your opening, refer to the example above. The rough opening should be the same
size as your door (16 x7 door will require a 16' rough opening). The white "2 by" trimmer above is added
AFTER the rough opening, for a net finished opening of 15' 9". Please note there are 3 studs before
the finish trim/stud. This allows 4 1/2 inches of backing for the track to mount to.

Finished Opening Height - Same as door, or slightly under

Finished Opening Width - 2" - 3" UNDER actual door width

Also note, if your header does NOT extend to the outside point of these studs (as shown), or there is
no header or a smaller header, these studs must extend at least 12" above the door opening height.
Everthing needs to be flush on the inside, as pictured above.

INSIDE VIEW PHOTO - TRACK MOUNTING

Notice how the track mounts approximately 12" above the height of the door itself, and flush with
the horizontal track. it is important that the track mounts flush from floor to at least 12" above door
height on each side, and flush in the middle where the spring bracket mounts (see next photo).
