Stewart Filmscreen Corp B - Manual (Page 12)

Installing the screen trigger interface option
The optional 12V screen trigger interface enables up and down 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.
Note: An optional 12V DC transformer is used if there is no 12V power
source from the projector or AV control center.
Preparing the connection
Before making the electrical connections, you need:
‹ An available 120V AC constant power source installed near the
screen
Making the connection
The electrical diagram in Figure 8 illustrates the connection.
1. Plug the AC power cord into the AC outlet.
2. Attach the 12V trigger wire to the jack on the back side of the
case adjacent to the power cord.
3. Use the supplied quarter-inch mono phone plugs to terminate the
12V trigger wire.
