REMOTE SWITCH CONTROL 

 

GENERAL REMOTE SWITCH OPERATION - A SMALL THEATER EXAMPLE 

 

During  theater  operation,  the  lighting  is  controlled  by  external  momentary  switch  closures  either  manually  or  by 
automated equipment.  The AT-402 dimmer is designed to activate preset lighting conditions in response to these 
controls. 

 

A simple scenario is described in the following table.  The table is for an installation where a four channel unit is 
used.  AT-402 dimmer channels 1 and 2 are connected to the house lights and AT-402 dimmer channels 3 and 4 
are connected to the stage lights.
