The WP401 is capable of controlling four outputs or groups of outputs. Full On and Blackout buttons are provided on both models. The Full On button causes all assigned outputs to be taken to their highest levels. The Blackout button causes all assigned outputs to be turned off. WP401 wall plate must be configured to control the desired outputs or group of outputs prior to installation. Wiring from the DP12/2400 Commercial Dimmer panel must then be connected to each wall plate. When all required setup and wiring have been completed, the wall plate may be mounted to a wall or other fixed structure.
