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 momentary wall switch.

Preparing the connection

Before making the electrical connections, you need:

‹An available 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)

‹A 4-conductor high-voltage hook-up cable, if the control is to be mounted at a location away from the frame

‹Cat 5, multi-conductor unshielded, or similar type electronic cable can be used to connect the 3-button switch to the LVC. The recommended wire gauge is 20 to 24 AWG. Use plenum-rated cable when required.

Making the connection

Figure 10 illustrates the connections.

1.Mount the low-voltage control box near the mask.

2.Connect the low-voltage control box to the mask by connecting the mask 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 AC power source by connecting the AC line voltage to the power strip terminal block located on the circuit board of the control box.

4.Connect the switch to the low-voltage control box.

5.A parallel connection to an outboard audio-visual switching network can be made at this time. (optional) Use only momentary switches for this option.
