What is it?

 The STI-2 is an electronic relay that receives a 12vdc trigger input signal that activates or turns on the electric motor to deploy the projector screen.

How does it operate?

When the 12 vdc trigger input signal is sent, the LED indicator will light up and remain lit while the screen is “down”. When the trigger signal is terminated, the LED will go out and the screen will retract.

It is important to remember to allow the screen to fully deploy or retract before switching directions of the trigger signal.

TIP: Never reverse a trigger signal when the motor is operational. Always allow the motor to fully cycle and stop before sending or removing the trigger signal.

What screen models use it?

Most small retractable electric screens can be connected to an STI Wall Plate including: 

• Luxus Model A
• Cascade G1 and G2
• Stealth
• LX
