TRAPDOOR Projection Screen
Thank you for purchasing the Screen Technics Trapdoor Projection Screen
Please review the following points fully before attempting to begin installation.
Description
The Trapdoor Projection Screen provides a solution for in-ceiling installation with a self closing automated door,
to hide the projection screen when not in use.
The system is contained within an MDF constructed box with a fully painted and finished underside including
integrated ceiling edge strips, so that once installed no plaster work or painting is required.
The rear door is the one that opens during normal operation, with the front door opening only for service issues.
Installation
With the main box being of MDF construction the installer can fix any brackets that are suitable into the 18mm
thick MDF box walls or utilise the captive nut-serts – 5/16 Whitworth thread - 4 off supplied, for threaded hooker
rod or eye-bolts for chain suspension of the unit.
Unit should be lifted into position being careful that the ceiling edge strips are level and flush with any ceiling line
or ceiling material, then fixed into position.
The installer must make sure the structure the unit is attached to, is sufficiently secure to handle the weight of the
unit, which will vary from different size to size screens – seek advice from the sales department if weight is an
issue in the installation.

The power cord will exit from the left hand side of the box, unless ordered otherwise. Now power the screen
down while being careful of the following warning.
Note: The door should open in the first second of operation, if this fails to happen, stop the screen at once, and
open it by hand, as sometimes the door is forced closed during transportation or installation.

The dimensions below are indicative of standard specifications, but if the screen is of a side tension variety, then

Point 1 - The screen comes with a standard 3 pin power plug which suitable for Australian and New Zealand
GPO’s (general power outlet).
The projection screen can be operated in three ways:
2 Channel Infra Red Remote Control - supplied
Impulse wall Switch – Up & Down (supplied by others)
Dry Contact Closure – Two momentary contacts (one for UP and one for DOWN)
Point 2 - Infra Red Remote Control
The projection screen is packaged with a 2 channel Infra Red Transmitter
and a 2000mm long IR Sensor, already connected to the screen and
exiting the rear of the canister.
Position the IR Sensor Eye with double sided tape or a U Pin, so that it can
be seen from where you wish to operate the projection screen, and use the
up and down buttons on the transmitter on channels 1 or 2 to operate the
screen.
Point 3 - Impulse Wall Switch (supplied separately – Item Number 3500998).
The Connect Module equipped projection screen can also have simple wall switch operation, although due to
interior décor choices the actual switch itself is not supplied with the screen and needs to be sourced.
The Connect Module comes with a pluggable terminal block, located as plugged into the module, so that you
can wire the wall switch to the connector and then plug it into the control module itself.
Point 3 - Dry Contact Closure
This is the industry standard method of switching a projection screen via a Building Control
System, such as AMX, Crestron, C-Bus, etc…etc
It is operated on a SPDT (single pole double throw) switching standard with an Open,
Close and Common input port. It utilises the same connection as the above described
Impulse Wall Switch.
Point 4 – Daisy Chain Link to other connect Modules (cable supplied by others)
RJ11 6 Core Straight Through Data cable can link up to 9 devices for multiple products.
Point 5 – (Optional Accessory) Low Voltage Trigger Relay Module / Item No 3500404
Switches device upon the receipt of 5v to 24v DC from a projectors low volt output port, plugs
into the left hand RJ11 on the module.

Once you have chosen your switching method ensure that you refit the lid of the control box before applying
mains power to the Interfit Trapdoor Screen.
Note: As the Infra Red control is also used to perform a Connect module reset in case you are troubleshooting
any performance issues, it is recommended that the IR cable be left attached to the module even if it is not the
chosen operating method for your installation.
