1. General description
The ceiling mirror compact permits concealed installation of a data-video projector between the raw ceiling and suspended
ceiling of a room. Insertion into grid ceiling systems is particularly easy due to the adjustable holders for the T-carrying
profiles (module lengths 600 mm and 625 mm).
The projection beam is pointed onto the display wall via two mirrors from the ceiling. The first mirror is adjustable in height
and angle. A second, movable mirror will guide the projection beam from the first mirror onto the display wall.
The mirror flap can be covered with the ceiling cut-out on the bottom to „conceal“ the ceiling mirror visually. The mirror flap
is extended or closed by electromotor, e.g. via a dial switch/switch or via a media control. A limit switch sets the opening
angle. This sets the position of the upper picture edge. In case of electrical defect, the mirror flap can also be extended
manually with a tool.
The projector is placed on an adjustable projector platform in the ceiling mirror compact.
For projectors up to a smallest side length of max. 370 mm, setting and maintenance of the projector is possible through
the mirror flap. For larger projectors, an additional revision opening (maintenance flap) in the ceiling is required.

2.4.2 Adjusting Opening Angle of the Mirror Flap, Service Position
The opening angle of the moving mirror flap 5 determines the position of the upper image edge of the projection.
The angle can be set precisely by turning the knurled screw: 12 Turning clockwise opens the mirror flap farther; the
projection image is moved downwards on the display wall. The angle should be approx. 50° in the projection position.
Note: Before adjustment of the knurled screw for the desired end position, always extend the mirror flap a bit from the
end position first.
The change to the mirror deflection causes trapezoid distortion.

For the service, the mirror flap can be turned completely down after disconnecting the attachment sheets of the wire cables
on the left and right 7 of the holder.

3. Installation of ceiling mirror compact
Read the entire instructions before installation. Check the carrying capacity of the ceiling.
Only remove the protective films after completing installation!
3.1 Pre parations
Unpack the ceiling mirror, put it onto a soft blanket, check the delivery for transport damage and completeness.
To adjust to differently sized projectors, the first mirror can be installed at three heights.
Install the mirror at a height so that the visual axis of the projector is about at the centre of the mirror. Then the projection
beam mostly hits the upper half of the mirror surface due to the visual Keystone angle of the projector.
Furthermore, the height can be adjusted on the oblong holes 4a .
The axis of the mirror should be horizontal 4a . The mirror deflection angle is pre-set in the factory at approx. 40°.
The angle can still be changed later via the setting screw 4b .
4b
4a
The holding angles adjustable in height 2 , 3 are already installed on the metal carrying frame 1 .
The projector is placed on the movable crossbeam with its front feet 9 . The crossbeam extraction can be installed on the
left/right. The rear feet are placed on the solid projector platform 10 , which can be installed in a total of six positions:
left, centre, eight and turned by 180° each. Install the projector platform so that the projector is standing stably with all feet
and the lens hits the first mirror centrally.
Remove the crossbeam 9 again. The T-frame 6 for the ceiling closure is installed after installation of the ceiling mirror,
when the mirror flap is extended.
3.2 Determining Installation Site
3.2.1 Position and Distance from the Canvas
For the entire projection beam to hit the two mirror surfaces, a distance ratio of the projector
(ratio = distance : picture width) of at least 1.5 is needed.
The visual axis of the projector and the middle axis of the ceiling mirror must be precisely at right angles to the canvas.
Otherwise, there will be a trapezoid horizontal distortion that cannot be visually compensated anymore.
A laser meter can, e.g., be used to comfortably perform perpendicular alignment.
To determine the distance from the ceiling cut-out to the canvas, assume a suspended position of the projector right
below the ceiling, and determine the projection distance with the specified projection ratio and the desired canvas width.
The double mirror deflection then specifies the front edge of the closed mirror flap (= ceiling cut-out edge) by
approx. 50 cm closer to the canvas.
Due to tolerances, it is recommended to include a reserve that can be compensated with the projector zoom.
Before opening the ceiling, check the precise installation location again, best using a test projection with the intended
projector, since lens tolerances or print errors in picture size tables cannot be fully excluded.
Depending on projector size, an additional revision opening must be provided.
10
3.2.2 Up/Down ratio
The double mirror deflection does not change anything about the vertical Keystone angle of the projector visually.
The vertical Keystone angle of the projector determines the upper canvas edge at distortion-free projection.
A larger Keystone angle of a projector model permits lower installation of the canvas. If the upper edge of the picture with
the opening angle of the mirror flap 5 is changed beyond this, there will be trapezoid distortions that can be equalised
again with the electronic Keystone correction of the projector. Observe that this will make the picture a little smaller, which
you can compensate by the zoom. There may also be visible loss of picture quality.
When the zoom objective is set to at least ratio 2.0 (direction tele range), beneficial specification of the projector beam path
on the first and second mirrors also permits a noticeably lower picture upper edge at distortion-free projection.
3.3 Integrated Installation in the Ceiling
The space required for the ceiling mirror must be present in the ceiling, see technical data in section 2, device description.
The ceiling construction must be able to bear at least 4 times the max. weight of the ceiling mirror and projector at the
installation point. For this, the ceiling around the installation site may need to be reinforced or additionally held on the
load-bearing building ceiling with suitable suspensions.
The surface of the solid ceiling should be smooth and clean so that no particles can fall onto the ceiling mirror and projector
in operation. Insulation materials must be sealed with PE film. It is also recommended to produce a box around the installation site in the ceiling that protects from looks and dust with the mirror open.
At the installation position, a triple 230 V~ socket for projector mains unit of the ceiling mirror, and a possible additional
device must be installed. It is of benefit if this is connected so that it can be deactivated via a main switch. This has the
benefit that the projector cannot be activated accidentally behind the ceiling. Furthermore, all necessary video and audio
cables, projector control cables, open/close switches for mirrors, must be provided under observation of the common
installation guidelines.
3.3.1 Mounting in the Suspended Room Ceiling
Cut a section of BxD (B in parallel to the canvas): 383 x 378 mm precisely and cleanly into the suspended ceiling
(e. g. plasterboard, panels, wood, etc.) in a suitable location. The ceiling cut-out (up to 1 kg) can later be inserted into the
T-profile insertion frame 6 of the moving mirror flap.
If the necessary carrying capacity cannot be established, the ceiling mirror can also be attached directly to the solid ceiling
above with the threaded rod set (7469 000 014 using four threaded rods M8, 1 m) and the corresponding attachment
material.
Attention: Observe installation provisions; only use suitable steel dowels and screws to attach the threaded rods to the
solid ceiling (not enclosed).
Installation via other suitable suspension mounting systems in the solid floor ceiling is possible as well.

3.3.1.1 Mounting and Installation of theProjector
➡➡ Wire plug-in screw clamp for switch OPEN/CLOSE and connect to OPEN/CLOSE socket 13a . Connect the mains unit
9 VDC to the socket 13b and plug it into the mains socket.
➡➡ Insert the ceiling mirror diagonally through the ceiling opening and position it so that the mirror flap will fit centred into
the cut-out.
➡➡ The mirror flap must end flush with the ceiling: Extend mirror flap and mount T-profile frame according to section 3.3.3,
close the mirror flap; the mirror flap is made flush with the ceiling by setting the height of the holders 2 and 3 .
If required, repeat the procedure until it is precisely flush.
➡➡ Fasten the ceiling mirror on the ceiling with four matching screws (not enclosed) using the holders 2 and 3 , see the
following top view.

precisely. Perform test projection: Adjust picture focus, picture size (zoom).
➡➡ Manually lift the mirror flap slightly and attach the wire ropes again on the left and right 7 ; close the mirror flap
with the motor; the flap will run against the stop 8 via the tensioning spring and stop; this end setting has been
performed in the factory.
➡➡ Check the opening angle of the mirror flap 5 according to the description in 2.4.2, or fine-tune all mirrors and the
position of the projector. If the projected picture shows any trapezoid distortion, correct by lens shift, if present, or by
electronic Keystone correction; adjust image size (zoom).
12
3.3.2 Mounting in Ceiling Grid 60 x 60 cm or 62.5 x 62.5 cm
The ceiling mirror is installed in the ceiling instead of a ceiling panel of the ceiling system. The cut-out can be inserted into
the mirror flap to unobtrusively cover the used ceiling mirror. The ceiling constructor uses the remaining cut-out of the
ceiling panel to cover the remaining part of the opening.
Open the ceiling grid in a suitable location. The carrying construction of the ceiling grid must be able to bear four times the
maximum weight of the ceiling mirror and projector. If necessary, the subconstruction must be reinforced.
3.3.2.1 Mounting and Installation of theProjector

3.4 Manual Opening of the Mirror Flap in Emergency
At power outage or technical errors, the mirror flap can also be opened manually in order to provide access to the system.
Drill a bore with diameter 5-6 mm that you can close with a blind plug according to the following sketch. It is recommended
that the bore be placed during mounting already.
The mirror flap can be opened manually at the display pending with a hexagon screwdriver “4 mm” or a cordless screwdriver with a 4 mm hexagon insert: A left-hand turn opens the flap (extremely slowly through transmission), a right-hand
turn closes the flap. Now error analysis can be performed with the flap opened.
