4. Pre-Installation
Before installing the projection screen, review this section thoroughly to be sure that no additional work is needed
to prepare the job for mounting and controlling the screen.
4.1. Required for Installation
Have an assistant help with installation to prevent damage or injury. The following tools will be needed to complete
the installation:
• Phillips Screwdriver
• 2 Step Ladders
• Electric or Cordless Drill
• Level
• 7/32” Masonry Drill Bit to install 8mm concrete anchors
• 5/32” Drill Bit to install 6mm Wall Switch Screw anchors (optional)
• Marker
4.2. Unpacking the Projection Screen
As you unpack the projection screen:
• Remove all accessories from the box before
discarding any packaging. Use the Package Contents
section to verify that everything has been removed.
• After the screen is out of the packaging, remove
the tape holding the bottom rail of the screen in the
housing.
• Do not remove the black bands from the ends of the
projector until it has been mounted. These bands
keep the bottom bar from falling into the housing and
getting stuck.
• While unpacking and preparing the projection screen for installation, take note of the location of the adjustment
screws and grommet. It may be difcult to locate them after the screen is hanging from the mounting brackets.
• Do not turn the adjustment screws until the screen is mounted and ready to be adjusted.
4.3. Powering the Screen
Operating Voltage: 110 Volts AC
Amperage: .96 Amps
The screen has a ve foot power cable permanently attached to the left side of the screen as seen from the
viewing area. Install or locate a receptacle close enough to plug the screen in prior to installation.
4.4. Mounting Considerations
The design of the brackets allows for wall, ceiling, or hanging mounting. Plan the nal height of the screen’s
viewing surface prior to installation. Make sure there is enough room for the screen to hang freely below the
mounting location when extended.
Warning! The building structure and material in the mounting location must be capable of safely supporting
the weight of the projection screen. Included hardware is only meant for use with wood, surfaces with
wood bracing behind them, or concrete surfaces. Conrm with an engineer or contractor that the building
material will safely support the weight of the screen using the included mounting hardware.
4.5. Control Method
Dragony motorized screens can be controlled via manual wall switch, IR remote, 12 volt trigger, or RS232.
Complete instructions for each method are described in the Control Setup section (Page 8). Decide on the method
that will be used before installation begins. Pre-wire any cables from projectors or control systems prior to closing
the walls or ceiling.

5. Installation
5.1. Installing the Brackets
5.1.1. Mounting Brackets
1. Measure the width of the Projector Screen Housing (Dim. “B” in Section 12. Dimensions and Weight) and
subtract 8” to estimate the distance the brackets should be mounted apart.
2. Mark the location of one bracket on the mounting surface, then measure to the planned location of the second
bracket. Adjust the general location of each bracket to allow for both to mount securely to wood or concrete.
Be sure that wall-mounted brackets are level before installation.
3. Mark the screw holes for each bracket and install them:
Top of Brackets Must Be Level
Top of Screen Housing Will Be Here
Approximate Distance = Screen Housing Width Minus 8"
The mounting brackets can be attached anywhere on the screen housing, but they should be about 4” from
each end to ensure that vibration or noise is prevented during operation.
Mounting to Wood Joists or Studs
Use the included mounting screws to secure the projector
mount brackets to the surface.
• No pre-drilling is necessary for most applications.
• Use 4 of the 8 included screws to mount each bracket
as pictured.
Warning! If holes are pre-drilled, use no
larger than a 5/32” bit. Larger holes will not
properly grip the threads, and the projection
screen could fall.
Mounting to Concrete Ceiling or Wall
Use the included anchors for the mounting holes and install
the screws into the anchors.
• Use a 7/32” masonry bit to drill a hole for each screw.
• Insert the anchors into the holes until they are ush.
• Do not install anchors into mortar joints.
• Use 4 of the 8 included screws to mount each bracket
as pictured.

1. Loosen the lock screw on the bottom of each bracket completely by turning the screw on the bottom counter-
clockwise until it stops.
2. Set the screen on the brackets according to the diagram. The screen will hang from the brackets before they
are tightened.
3. Check the position of the screen and make any left or right adjustments as necessary.
4. Tighten the lock screws at the bottoms of the brackets and then check the screen housing using a level.
Make any adjustments necessary.
5. After securing the screen, remove the black bands holding the bottom bar in place.
6. Leave any control wiring separate for the moment, and plug the power cord into a 110V AC outlet.
Pg. 8
5.3.Test the Screen
After the screen is secured to the mounting brackets, the unit can be tested. First, make sure the bottom bar of the
screen is moving freely in the housing. If the packing screws/tape were not removed prior to installation, they must
be removed before trying to move the screen position.
Find the manual test switch at the bottom-left side of the screen housing. Press the switch once and the screen
should begin moving down. If nothing happens, make sure that 120 V AC is present at the power outlet.
Allow the screen to move down until it stops on its own, then press the button again. The screen should close
and stop with the bottom bar back in the original position. If everything is working correctly, continue with the
installation. For any issues see the Troubleshooting section on page 13.

6.2. IR Control (With Optional IR Receiver Extension)
The IR receiver built into the front of the screen works with remotes up to 26ft away at a maximum angle of 30°.
The included external IR receiver can be connected to the EXT IR port if additional range is needed.
To use the external receiver, plug it into the screen and have an assistant hold the receiver in different mounting
locations until the remote works reliably from where it will be used most. Mount the IR receiver using the adhesive
foam tape on the back.
Note: The included external IR receiver is proprietary to Dragony projection screens. Other IR receivers will not
work correctly.
6.3. 12 Volt DC Trigger Cable
Screens may be lowered and raised by a 12 volt trigger signal sent from other equipment like a projector. A proprietary, 33ft cable is included for connecting a standard 1/8” (3.5mm) mono mini 12 volt trigger port to the TRIG port
of the projection screen.
12 volt trigger operates by sending a 3-12V DC signal to the screen when the projector turns on. The screen will
lower and remain lowered until the projector is turned off and the voltage drops to 0v (zero).
Other control methods may be used with 12V trigger. However, the screen will remain lowered for use if voltage is
present on the trigger while an attempt is made to close the screen.
Important! The projection screen still requires external AC power for operation. The 12 volt trigger connection will
NOT power the screen. Plug the AC power cord into a suitable outlet supplying 120V AC.
6.4. Manual Wall Switch
The included wall switch may be surface mounted near the projection screen for manual control. A 10ft RJ12 cable
is included to connect the switch to the screen. This cable may be replaced with a custom Cat5e/6 cable if longer
runs are required due to the location of the switch. See the next page for complete instructions.
6.5. RS232 Serial Control
Pins 1 and 2 on the EXT CTRL port may be connected to a control system serial output for one-way control.
Please see the DFM Motorized Screen Control Protocol for driver and command information, available on the Support tab at the DFM-NTT product page at www.SnapAV.com. The diagram illustrating the correct pins to use for
RS232 and instructions to extend the wiring from the screen to the control system are on the following page.
6.6. Contact Closure/Relay Control
The Dragony motorized screen may also be controlled via contact closure or relay control. Using the same
conductors that are used for the wall switch, momentarily short the Common wire to the Up, Down, or Stop
wire for the desired operation. The diagram illustrating the correct pins to use and instructions to extend the wiring
from the screen to the control system are on the following page.

6.8. Extending Control Wiring
6.8.1. Wall Switch
1. Run a Cat5e/6 cable from the projection screen EXT CTRL port to the switch location. Install the cable into the
wall at the switch location, and cut a 1” hole at the desired switch height. Pull about 6” of cable out of the hole
for attachment to the wall switch.
2. Remove the knockout from the switch back-box and mount it over the cable with the RJ12 port opening pointing
down. Use the supplied screws and anchors to secure it to the wall.
3. Cut the RJ12 control cable. Leave about 12” of cable attached to the connector. Splice four of the Cat5e/6
conductors to the appropriate wires as shown above at the projection screen. Then, plug the RJ12 into the EXT
CTRL port. Insulate the ends of the unused RJ12 conductors 1 and 2 to prevent short circuits.
4. Strip the insulation from each of the four conductors used in the Cat5e/6 cable about ¼”. Locate the press-t
connector on the switch assembly and terminate the conductors as shown above. Make sure to match the pinout correctly between the screen and the wall switch.
5. Mount the wall switch to the back-box so that the up and down buttons face the right directions.
6.8.2. Contact Closure or RS232 Control
1. Run a Cat5e/6 cable from the control system processor location to the projection screen.
2. Cut the RJ12 cable and leave about 12” of cable attached to the connector.
3. Terminate conductors in the Cat5e/6 to the desired pins of the RJ12 connector as shown in the diagram above.
Insulate the ends of the unused RJ12 conductors to prevent short circuits.
4. Terminate the same conductors to the appropriate wires on the RS232 port or contact/relay connection of the
control system processor.

Grommet
Viewing Area
Closed Limit Screw
(toward back of housing)
Left Side
(Looking UP at the bottom of the screen while standing underneath)
7.1. OPEN Limit Adjustments
The OPEN screw (closer to the viewing area) adjusts how far down the screen moves for viewing and how much
of the black material above the viewing area is seen when the screen is in use.
• Access the OPEN screw by placing the adjustment tool into the housing through the access hole after
removing the white adjustment hole grommet, and bending it toward the screw until it can be inserted.
• Turning the OPEN screw COUNTERCLOCKWISE will INCREASE the black space above the viewing
area.
• Turning the OPEN screw CLOCKWISE will DECREASE the black space above the viewing area.
• Turning the screw TWO complete revolution will change the amount of black material seen
approximately ½” inch.
7.2. CLOSED Limit Adjustments
The CLOSED screw (away from the viewing area) adjusts how far down the bottom bar of the screen hangs
when the screen is rolled up into the closed position.
By default, the screen is set so the bottom bar will hang ush with the opening in the screen housing.
Adjust this setting only if the bottom of the screen must hang lower than the default setting when
closed. Changing this setting incorrectly may damage the screen and is NOT covered under warranty.
• Access the CLOSED screw by placing the adjustment tool into the housing through the access hole
after removing the white adjustment hole grommet in the bottom of the screen housing.
• Turning the white screw CLOCKWISE will cause the bottom rail to sit LOWER when the screen is
closed.
• Turning the CLOSED screw COUNTERCLOCKWISE will cause the bottom rail to sit HIGHER when
the screen is closed. Do not turn the CLOSED screw counterclockwise unless the bar is already
sitting too low after adjustment.
• Turning the white screw two complete revolutions will change the amount of screen left hanging
approximately ½” inch.
After setting is complete, check the full range of motion again using the manual switch so that the screen can
be quickly stopped if there is any issue.
