The Instant roll door is
designed primarily for
internal applications or
where wind or air
pressure is minimal.
The Instant Roll door
structure is manufactured
from galvanised steel and
powder coated in a range
of standard colours.
It is
self supporting only
needing to be fixed to the
floor through its feet and at
high level for security and
rigidity. The two legs
incorporate nylon brushes
to both help guide and seal
the curtain and also
provide the fixing for one
self monitoring safety
photo beam approx 400m
off finished floor level.
The
casing spanning the legs at
high level known as ‘the
platform’ incorporates the
geared brake motor with
built in limits and is
connected by a special
coupling to the aluminium
barrel that raises and
lowers the curtain. The
safety edge ‘envelope’ is
designed to provide a
reasonable seal to the
floor.
The bottom of the canvas
curtain is reinforced with a
horizontal steel rail secured
at its ends to vertical guide
wires to keep the curtain
taught and provide
resistance against minor
wind loads. A 500mm deep
full width vision panel is
provided as standard.
All doors are supplied
with an internal push
button, one photo-electric
safety beam and a stop
and return safety bottom
edge as standard. A full
range of activation
equipment is available and
is described on page 11 of
this brochure.
Our doors are built and
factory tested prior to
delivery. This, together with
simple design, ensures that
our doors are installer
friendly and can be fitted in
the minimum time.
Most
wiring connections are
made using multi pin plugs
for ease of installation. All
activation and safety
equipment is easily
connected to numbered
terminals within the main
control panel. The doors
are all delivered with full
fitting and wiring
instructions.

Electrical specifications
and activation systems
All door types are
supplied with a geared
motor designed for
intensive use. The
motor is connected to
the shaft by a flexible
coupling to absorb any
vibrations produced,
thus increasing the
operator’s life span.
The motor incorporates
factory set limit switches,
an electric brake and
emergency brake
release.
The door can be opened
and closed in the event of
power failure by hand
crank. A safety interlock
micro switch ensures that
the door cannot be
operated electrically unless
the hand crank has been
replaced.
