DESCRIPTION
The LS-4C is a low voltage wall switch designed to work with the
Lightsaver LCD-203 or LCO-203 Daylighting controllers. The LS-4C
can override the controller for manual light level adjustment or ON/OFF
control. Dimming is available when used with the LCD-203. Up to four
LS-4C switches can be connected in parallel to one controller to
provide multi-way switching.
WIRING
The LS-4C is supplied with color coded wire leads. To make wiring
connections, use either the LCD-203 or LCO-203 wiring diagram
below, as appropriate for your application.
Use 18 AWG 5-conductor cable to connect the switch to the LCO-203
controller. Use 18 AWG 7-conductor cable to connect it to the
LCD-203. The maximum wire length from the controller is 150 feet.
Wiring is Class 2 rated. Consult local codes for conduit requirements.
Note: Low voltage wiring must be isolated from the line voltage wiring.
