Make Note of your Serial Number: ____________________________

•Electric or Cordless Drill
•Level
•Pencil
•Screwdriver
The screen has a nine-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.
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.

4.1 Mounting to wood Joists or Studs
No pre-drilling is necessary for most applications.
4.2 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 flush
•Do not install anchors in mortar joints.
Cirrus Screens can be controlled via Manual button, IR remote, wireless 12-volt trigger, RF remote, or RS232.
Complete instructions for each method are described in the Control Setup section. Decide on the method that will
be used before installation begins to avoid any issues with control later. Pre-wire any cables from projectors or
control systems prior to closing the walls or ceiling.
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.

Controller Port Configuration:
Baud rate: 2400
Data Bit: 8 bits
Initial Bit: 1
Parity: None
Stop Bit: 1
RF Control:
The RF remote works within 30 meters from the screen. Certain construction materials could negatively affect this
range.
Manual Control:
In order to manually bring the screen UP, DOWN and to STOP it, you can click the manual control switch which works on
a continuous cycle.
RS232 Serial Control:
The screen can be controlled via RS232 serial to perform the functions UP, DOWN, and STOP by connecting to
pins 1 and 2 on the EXT CTRL RJ12 input. This is a one-way communication, so no status is available back to the
automation controller.

EXT CTRL RJ12 Pins:
RS232 control uses pin 1 for Ground (GND), and 2 Data Receive (RXD) on the EXT CTRL RJ12 jack.

The Cirrus Screens motorized screen may also be controlled via contact closure or relay 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
below. 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.

Cirrus Screens are designed to provide many years of trouble-free use. After the screen is installed and adjusted, no
further maintenance is required for the operation of the screen, unless the viewing surface gets dirty. Follow these
guidelines to clean any marks or residue from the viewing surface:
•Do not clean the screen case with water
•Wash the screen with a mild organic cleaner diluted with water and ensure to clean the entire screen not just
one spot.
•Use a dry Microfiber cloth to clean dust and dirt from the housing and screen on a regular basis.
7. Adjusting Screen Length Limits:
We recommend that only an experienced AV installer to undertake below procedures:
Deployed Limit (Amount of Black Drop):
•Red screw
•If the picture is too high on the screen you can reduce the amount of black drop. As seen in the diagram above,
turning the (A) (RED) screw counter clockwise will REDUCE the amount of black drop.
•If the picture is too low, you will need to lower the screen casing. Only, if the black drop has already been
reduced (as in the step above) can you increase the amount of black drop. The screen comes from the factory
with the maximum amount of black drop.
•Trying to lower it further will cause the screen to roll back onto itself and could void the warranty. Contact your
dealer if you are unsure about how much black drop is available on your model.
•Turning the screw 2 (two) complete revolutions will change the amount of drop by approximately 1 inch.
Retracted Limit:
•White screw- This limit is factory set and we recommend that it is not altered.
•Altering this adjustment could cause the screen to retract too far into the case or to overdrive the motor. Doing
this will void warranty.

Since Cirrus Screens are designed for function trouble-free that will last for years of enjoyment. Most problems
that occur are due to simple issues. If you have trouble, please check the list of simple fixes below. If the problem
persists, please contact your authorized dealer.
•If you want the batten bar to sit outside of the case when the screen in closed, then turning the (B) (White)
screw counter clockwise will cause the bar to sit LOWER when the screen is closed.
•Turning the screw 2(two) complete revolutions will change the amount of drop by approximately 1 inch.
8. Programming Remote:
1. press the Manual Switch button to deploy the screen for about 20 cm then press is again to stop. (this procedure
slows a better view on the motion of the screen only)
2. Press and hold the Manual Switch button for approximately 5 seconds until the screen will move up or down one
time, then release the button. The screen is now ready to pair the remote.
3. Press the UP button on the remote once. The screen should move up and down once, showing the signal was received
and the remote has been paired successfully. Try the UP/STOP/DOWN buttons to check the functions.
4. On step 3, if the UP button is not pressed within 8 seconds, then the code pairing operation will be cancelled, and you
will have to go back to step 2.
Issues:
Solution:
Screen does not react to any control
•Power cable to the film screen is incorrectly
connected or plugged into an outlet that does
have power.
•Check connections and verify power on the
outlet.
•Check control method selected (IR or low
voltage) and try an alternate method.
Screen goes lower than desired or does not retract far
enough
•Adjust the up and down limit as described.
RF does not work
•Check the batteries in the IR/RF remote that you
are using.
•Ensure that you are within range of the remote
being used. The factory remote will work at a
distance of up to 8m/30m in most situations.
•If you have chosen to “hard-wire” the IR
connection into a RJ-11 connector, be sure that
you have the appropriate wires on the correct
pins, ad described in the RS232 control section.
Other Troubleshooting Tips:
•The screen is built with a thermal overload protection for the motor. If the screen stops moving up/down, then
the protection circuit may have kicked in. This can happen when programming the screen and it is moved
up/down several times within a few minutes. This will reset after approximately 10 minutes.

•If the manual button is used to program screen limits, then you may have inadvertently reprogrammed the 12v
trigger or RF remote. Make sure to use the switch under the rubber plug to set the limits on the screen.
•If the screen moves by itself, it maybe in programming mode. Please make sure the Manual control button is not
jammed and moves freely.
