Installing the low-voltage 3-button switch (standard)
The 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:
KAn available 120V AC constant power source
KA 4-conductor switch hook-up cable (4-conductor bell wire or category 5 cable is typically used for long runs)
Making the connection
Figure 2 illustrates the connections.
1.Remove the J-box covers, using a standard screwdriver.
2.Connect the 4-conductor cable to the connection harness coming from the J-box used for switch input, via an electrical knockout.
3.Connect the hookup cable to the 3-button switch.
4.Connect the main 120V AC power source to the the J-box used for the main AC power connection, via an electrical knockout.
