How to prep the side columns
1
Remove
the covers on both side columns.
Screws for side column covers run in a vertical line. There is also one screw at the base of the column.
2
Beginning in 2022,
the BTA4 Bluetooth
®
user terminal is a
standard feature of Spiral prewire doors.
▪
The BTA4 can be
preinstalled
in a side column, or
field installed
at a location remote from the door.
▪
If you do not see
a BTA4 terminal preinstalled
in either side column, check with the door
owner for where they want the terminal installed,
and read
(Optional) How to install the BTA4
user terminal in a remote location
on page 22.
Check all surfaces
on side columns
and head assembly for protective film.
Remove
film.
Covers may have one, two or three panels
depending on height.
Keep covers intact –
DO NOT remove screws
that run horizontally (shaded area).
The SmartSurround™ light curtain on the side column
cover connects through two cables labeled “01”.
Make sure
the cables are disconnected when you
remove the cover. You will reconnect them later.

the vertical guide tracks for the door panels are in the fully lowered position.

the holders on the vertical guide track.
If necessary,
lower the track.
Do this
for both columns.

Select one holder at the halfway point of the side column and
hand tighten the screws
to
secure the guide track in place.
Do this
for both columns.
The tracks can now be repositioned easily after the side columns are installed, but will not slide
while the columns are being lifted into place and leveled.
After the head assembly is in place,
raise the track
to meet the curved
track in the head assembly.
The locating pins align the two tracks.

Door ships with each
track set below the
lip of its side column.
This protects the
locating pins
while the
head assembly is being
raised into place.
Loosen, but do not remove,
each pair of track holders.
The number of holders varies
based on the height of the column.
The track should slide freely
when you are done.
