aboUt YoUR sKYfolD Wall
Congratulations on your purchase of your Skyfold Wall System, the most
technologically advanced and only vertically folding operable wall of its kind.
Before operating your Skyfold wall, please read this manual carefully, as this owner’s
manual includes a description of the wall’s major components, as well as procedures
related to the operation of the wall, a maintenance schedule and explanations
regarding the warranty.
Your Skyfold wall is a fully automatic, operable wall that is activated by applying pressure
to 2 switches simultaneously. in addition to simplicity of operation, please note that
your Skyfold wall was designed with safety as a primary concern. This is reflected not
only in the design philosophy of the system, but also in certain specific subsystems
and components, as follows:
➢ the wall’s movement is stopped instantly when
-
pressure is released from either switch.
a loss of power occurs.
a mechanical jamming occurs. (up direction only)
excessive current is being drawn by the motor.
the infra-red sensor detects an obstruction across the length of the wall
and automatically reverses the wall for 3 seconds.
➢ if, at any given time, the downward wall speed is substantially higher than
normal, a hydraulic checking device lowers the wall speed.
➢ the cables used to lift and support your Skyfold wall are of the highest
strength and quality. in the unlikely event that a cable fails, this will not affect
any of the other cables.
➢ the programmable logic controller cuts off power if a short circuit is detected
on the 12V or 24V line or if polarity is reversed.
➢ the electrical control box contains the latest in overload protection
(models >1HP) and other electrical safeguards.
➢ the interface between the gearbox and the line shaft also ensures a high
degree of safety.
➢ the movement of the wall is triggered by two switches,
thus increasing security.

Europe & Asia
in an effort to optimize the safety features provided by the Skyfold wall, two switches
are installed at opposite sides of the Skyfold wall. These switches control the wall’s
movement. Both switches must be activated simultaneously for the wall to move
upwards or downwards, while the key is turned to the desired position. This ensures that
there are two people present at all times during the operation of the wall.
when one of the switches is released, the wall stops immediately, without coasting.
The keyed switch plate includes an illuminated push button that flashes fault codes if the
Skyfold wall does not work when activated. One to ten flashes represent ten different
flash codes.
Before operating the switches, please read the safety precautions and the procedures
contained in the Skyfold walls in operation section.

The internal skeleton of the Skyfold Mirage wall consists of a series of lifting
mechanisms or pantographs that are made of structural grade aluminum and steel.
For greater longevity and silent operation, all mechanical pivot points are made of high
strength steel bolts or pins on plastic bushings. Aircraft-grade wire rope or cable, of the
highest strength and quality, pass through the mechanisms and fold and unfold the
mechanisms as they wrap and unwrap on their respective drums.
See Figure 2.
Figure 2: Pantographs and Panels (Mirage glass panels shown)
SKYFOLd MiRAGE RETRACTABLE wALLS 6
Glass Panels
Skyfold Mirage walls can either have a single glass composition
or a double glass composition.
The single laminated glass composition consists of 3/16” (5 mm) annealed glass +
0.060” (1.5 mm) film + 3/16” (5 mm) annealed glass. Overall thickness: approximately
7/16” (11.5 mm).
The double laminated glass composition consists of 1/8” (3 mm) annealed glass +
0.030” (0.8 mm) film + 1/8” (3 mm) annealed glass + 1/2” (13 mm) spacer + 1/8” (3 mm)
annealed glass + 0.030” (0.8 mm) film + 1/8” (3 mm) annealed glass. Overall thickness:
approximately 1 1/16” (29mm).
The glass panel’s construction also provides superior acoustic properties. Alone, the
double laminated glass panels have a Sound Transmission Classification (STC) rating
of 42 (Rw 42), according to industry standards.
Cables
The cables that lift and support the Skyfold wall are aircraft-grade wire cable of the
highest strength and quality. These cables are sized to offer a high factor of safety.
Each of these cables is attached to and lifted by a separate drum and each drum is
keyed into the solid-steel line shaft. in the unlikely event that a cable fails, this will not
affect any of the other cables. See Figures 2 & 5.
Sheaves ( pulleys)
As illustrated in Figure 2, the lifting cables wrap around the sheaves, thus providing an
additional pick-up point.
7 SKYFOLd MiRAGE RETRACTABLE wALLS
Infra-red Sensor
Located at the bottom of the wall track is an infra-red sensor. when the infra-red beam
is broken by an obstruction while the wall is descending, power is cut to the lifting motor,
the electromagnetic brake engages and the wall’s descent is instantly halted. it then
automatically reverses for 3 seconds. See Figure 2.
Warning
➢ After the wall has reversed direction, ascended for 3 seconds and
cleared the obstruction, you must remove the obstruction prior to
resuming the Skyfold wall’s descent.
➢ If the wall has incurred damage, do not operate the wall and call
your local, authorized Skyfold dealer for an immediate inspection.
End seals
Fixed brush and sweep seals close the gap between the wall track and the pantographs
(lifting mechanisms) thus providing a visual barrier. See Figure 3 for Skyfold Mirage.

Line shaft
This manual is accompanied by shop drawings that clearly illustrate
where the motor unit is located.
Electric gear motor ( lifting motor)
Your Skyfold wall is equipped with a sealed, heavy-duty gear motor that powers the
entire system. This lifting motor is designed for hundreds of stops and starts an hour
and is rated for service several orders of magnitude more severe than the service it
experiences while operating your Skyfold wall.
The lifting motor is equipped with an electromagnetic brake. Power to the lifting motor is
cut and its electromagnetic brake engages automatically when one of the following occurs:
➢ A switch is released.
➢ The wall reaches its upper limit, fully retracted into the pocket.
➢ The wall reaches its lower limit (fully closed position).
➢ while descending, the beam emitted by the infra-red sensor is broken
by an obstruction. This triggers the 3 second auto-reverse feature to clear
an obstruction.
➢ while ascending, the over-torque sensor detects excessive torque on the motor.
➢ The thermal-overload relay in models >1HP, which is located in the electrical
control box, detects excessive current being drawn by the motor.
➢ A short circuit is detected on the 12V or 24V line or if the polarity is reversed
➢ The main power switch, breaker or fuse is tripped.
Without power, the electromagnetic brake can be manually released by pulling the
brake release lever. This allows the wall to descend under its own weight. Its speed
is controlled by the hydraulic checking device. The system must be recalibrated
before it can be used again. Leave the control box disconnect switch in the off
position until it can be calibrated by a certified SKYFOLD installer.
Spring-cushioned torque arm
A spring-cushioned torque arm supports the motor assembly in order to soften the starts
and stops of the system. As part of this assembly, there is a sensor on the torque arm
that detects higher than normal torque levels. in the event that mechanical jamming has
occurred in the system, or if the upper limit switch fails to operate, this over-torque
sensor quickly cuts power to the motor. See Figure 5.
Line shaft
The line shaft that rotates all of the cable drums is continuous through the gear motor,
without a coupling. This assures a higher degree of safety by providing a better interface
between the gearbox and the line shaft. See Figure 5.
SKYFOLd MiRAGE RETRACTABLE wALLS 10
Hydraulic checking device (safety motor)
There is a hydraulic checking device, also referred to as a hydraulic parachute, which
is separate from the gear motor assembly and is powered by the line shaft itself.
See Figure 5.
when the wall is traveling downwards, this hydraulic checking device builds up a certain
hydraulic pressure that is dependent on the wall’s travel speed. in normal operation, this
pressure is very low and this checking device offers no appreciable braking force on the
wall. if, at any time, the wall speed is substantially higher than normal, this checking
device offers sufficient braking force to lower the wall at a speed of approximately 150%
of the normal operating speed.
Electrical control box
Skyfold’s electrical control box meets both Underwriters Laboratories (UL) and Canadian
Standards Association (CSA) requirements. The enclosure itself is constructed of
heavy-gauge steal. it is typically located within 15 feet (4.5 meters) of the motor unit
and is accessible via an access panel in the ceiling. For warranty protection, it has
a manufacturer’s seal, thus deterring unauthorized tampering.
There is a main power switch on the cover of the electrical control box. See Figure 5.
In the event that your wall does not operate at all, you must ensure that the main power
switch is in the “ON” position. Any other type of maintenance or repair work, in these
cases, must be performed by your local, authorized Skyfold dealer. Unauthorized work
will void the Skyfold warranty, as stated in the Warranty section of this owner’s manual.
Upper (opened) and lower (closed) limit control
Your Skyfold wall stops automatically upon reaching its upper limit (fully open) position
or its lower limit (fully closed) position. There is no need for the operator to carefully
time the release of the switches. These limits are set by the Skyfold installer at the time
of installation.
AV / Dry Contact for linked building systems
For integration with other building systems, your Skyfold wall is equipped with dry
contacts identifying when the wall is in the “UP” or “dOwn” position. The dry contacts
are sourced from the control box and are labelled as such. See Figure 6.
11 SKYFOLd MiRAGE RETRACTABLE wALLS
A maximum power supply of 24 volts is provided by the A/V system that is to be controlled
by these contacts. Skyfold provides a connector plug and a 6” (150 mm) long extension
cord to the A/V dry contacts found on the outside of the control box. See Figure 6. The
extension cord comes with a male and female connector and a separate female connector
is supplied for the connection to the A/V system. The male connector on the extension cord
has the following wire designations:
• Black #1 – wall down Com1
• Red #3 – wall Up Com1
• white #2 – wall down dry Contact 250mA
• Green #4 – wall Up dry Contact 250mA
Using 18 or 22 gauge wires, the electrician connects the A/V system to the pins in the
separate female connector. Access to the interior of the control box is not required for
this hook-up and a manufacturer’s seal deters unauthorized entry.
Warning
➢ Only qualified Skyfold personnel are authorized to perform any type
of maintenance and/or repair work on your Skyfold wall.
Unauthorized work will void the Skyfold warranty, as stated in the
Warranty section of this owner’s manual.

sKYfolD Walls In oPeRatIon
The time required for a Skyfold wall to ascend or descend varies depending
on the size of the wall. On average, a Skyfold wall will take approximately
two minutes to either completely travel upwards or downwards.
O P ERAT I N G A S KY FO LD WA LL
The following procedures apply to normal operating situations.
Warning
➢ Two operators, one per side per switch, are required for the
duration of the walls operation.
➢ Do not place objects between the panels, underneath the Skyfold
wall, or in the near vicinity of the Skyfold wall, as this can cause
damage to the Skyfold wall when it is in motion.
➢ Do not operate your Skyfold wall with persons or objects in the
path or immediate vicinity of the Skyfold wall, and ensure that both
sides of the Skyfold wall are clear.
➢ In case of a malfunction, do not operate the Skyfold wall or
attempt to repair it. In such a case, call your local, authorized
Skyfold dealer for service.
➢ Do not operate your Skyfold wall if there are any abnormal noises
or if the wall does not appear to be working properly. In such a
case, contact your local, authorized Skyfold dealer immediately.
➢ Do not operate your Skyfold wall if panels are missing as this can
damage the system.
➢ Heat generated by lights inside of the ceiling pocket can damage
the panels. Therefore, you must only turn on lights that are located
in the Skyfold ceiling pocket when the wall is completely down and
never when the wall is partially or fully retracted into the pocket.
➢ In cases where an obstruction has caused the Skyfold wall to halt
its descent, it will raise automatically (auto-reverse) for 3 seconds
to clear the obstruction. You must remove the obstruction prior to
resuming the wall’s descent.
1. Ensure that both operators of the Skyfold wall have a clear and unobstructed view
of the wall. The Skyfold wall must be monitored from both sides of the wall for the
duration of the wall’s ascent or descent, as this can prevent injury and/or damage
to the Skyfold wall.
2. At both switches, simultaneously, activate and maintain pressure on the switches
with the key turned in the desired position.
3. Release the switches when the desired position has been reached or after the wall is
stopped automatically by its upper or lower limit controls.

B ACK-UP O P ERAT I N G P RO CED URE
in the unlikely event that the Skyfold wall does not respond to the key switch operation,
it could possibly be operated by using a heavy duty drill. A shaft extension through the
fan cover of the motor allows for an alternate method of raising and lowering the wall.
The system must be recalibrated before it can be used again. Leave the control box
disconnect switch in the off position until it can be calibrated by a certified SKYFOLd
installer. Please note this diagram is for illustration purposes only.
Please contact your local authorized Skyfold dealer for complete operating instructions.
O P ERAT I N G M ULT I P LE, I N -LI N E WA LL S ECT I O N S
Multiple Skyfold wall sections, controlled from a single pair of switches but with their own
independent motor units, are used to create a monolithic barrier across long distances.
Regular fixed sweep and brush seals are used to close the gap between each Skyfold
wall section. All Skyfold wall sections operate simultaneously. However, the Skyfold wall
sections may take different amounts of time to reach their upper or lower limits because
there can be slight differences in the motor speeds of these Skyfold wall sections.
in this instance, the procedure to operate the Skyfold wall is the same as for normal
operating situations. However, the switches must be activated for the entire duration
that it takes all sections to reach their respective upper (open) or lower (closed) limits.
