SECTION 1.7
Doors Which Are
Not
Suitable For Automation
Read this section carefully !
For reasons of safety, certain doors should not
be automated. One door in particular fails to
comply with the safety standards set out in
SABS / IEC 60335 - 2 - 95
This door is commonly referred to as a "Tip-In"
or "Cam-Spring" type door.
DISTINGUISHING FEATURES
A
"one-piece"
type door which has a
"vertical"
guide track. The distinguishing feature of the door is
the placement of the
Guide Roller.
The
Guide Roller
is positioned at, or close to, the
bottom-most corner of the door panel. The effect of
this arrangement is that it causes the door to open
completely to the inside of the garage.
At no stage during the opening or closing cycle
does any part of the door pass through or
protrude from the opening.
When the door is fully open, the entire door remains
completely inside of the garage.
These doors were intended for use in openings that
have rounded or
"arched"
shapes and were sold as
a cheaper alternative to
Sectional
type doors.
All warranties, whether stated or
implied, shall, "ipso facto", be
rendered null and void if “Brano”
products are fitted to such types of
doors.
Do not automate this
type of garage door!

CAUTION! CAUTION! CAUTION!
These doors are unsafe for automatic operation
as the force applied by the door operator is
magnified as much as
40
times under the door
due to the action of the door mechanism. The
operator is unable to sense reliably
obstructions in the path of the door.
IMPORTANT NOTE:-
These doors are classified as
"Vertically
Tracked"
type doors.

“Tip-In" type doors are found.
