Installing the low-voltage 3-button switch option
The optional Stewart Filmscreen low-voltage control allows the use of low-
voltage wire to connect to the supplied 3-position 24V momentary wall
switch.
Preparing the connection
Before making the electrical connections, you need:
‹ An available 120V AC constant power source
‹ A 4-conductor switch hook-up cable (4-conductor bell wire or
category 5 cable is typically used for long runs)
Making the connection
Refer to the diagram that is located on the white label inside the steel
housing, and in Figure 9.
1. Mount the low-voltage control box near the screen.
2. Connect the low-voltage control box to the screen by connecting
the screen motor power leads to the power strip terminal block
located on the circuit board of the control box.
3. Connect the low voltage control box to the 120V AC power
source by connecting the AC line voltage to the power strip
terminal block located on the circuit board of the control box.
