Stewart Filmscreen Corp AVS-1005 - Manual (Page 8)

Connecting the Screen Trigger Interface (STI) option
The optional low-voltage STI enables operation of the screen in conjunction
with a projector, tuner, VCR, cable box, or switched AC outlet.
Once the AC power outlet is installed near the screen, an electrician is not
needed to connect the screen trigger interface to the power source. Attach
the 12 V trigger wire (2 conductor 20-24 gauge) to the jack in the J-box as
shown in Figure 4.
Use the switch or remote control to activate the screen. Do not block the
path of the door or screen when in motion.
When you lower or retract the screen, it will stop at its factory preset limit
and the door will close.
The motor is designed to be used for short operations such as raising the
screen in preparation for viewing. The motor is not designed for continuous
duty. If the motor operates continually for more than a few minutes, it may
automatically shut off to prevent damage from overheating. If the motor
occasionally needs to be run more than normal, for example during initial
setup and positioning, allow time for the motor to cool down.
In general, when a screen is not in use, you should store it in the fully
retracted position.
