Unsafe Installation Practices

Do Not Install Door Operators In This Way !

Single door operator centrally mounted

between two "One-Piece Tip-Up” type

doors or “Sectional” type doors which

are rigidly coupled together. ( Fig. 12 )

Unsafe Installation Practice No.1

Important Notes

SABS - IEC 60335-Part 2 - 1995 sets down

certain safety standards for the automation

of garage doors. When two doors are

coupled together in the way shown here, the

built-in "overload" sensors of the door

operator, regardless of make or type, may

be severely compromised to the extent that

they may not respond quickly enough, if at

all, to any obstructions in the path of the

door. This is a dangerous condition !

Should any doors which are automated in

this manner cause an injury, or worse, to any

person or damage to property, both the

owner and the installer may be held jointly

and severably responsible and liable; and

may suffer the consequences thereof.

Homeowners are advised to reject such

installations lest they be incriminated in

any claims.

Under no circumstances will Brano

condone the use of it's products in such

a manner.

“Side-Mount” Roll-Up Door System

“Cross-tube”

Connection Adaptor

Motor mounted

vertically at side

of door.

Steel Roll-Up Doors

Typically, the motor is

positioned vertically at one

side of the door. A”Cross-

tube” is fixed to the lower

extremity of the door as

shown in Figs 10 & 11.

The operator is coupled to

the “cross-tube”. The effect

of this arrangement is that

the door is raised or lowered

by a force being applied at

only one side of the door.
