Model WP101K wall plate controllers, designed to be used in conjunction with Applied Electronics Commercial Dimming System. Applied Electronics Commercial Dimming System consists of one DP12/2400 Master Panel and up to seven EP12/2400 Expansion Panels. The Master Panel provides the capability to dim twelve 2400 watt outputs internally, as well as control up to seven optional Expansion Panels. A variety of wall plate configurations are available for remote control of system outputs. Each wall plate can be configured to control a single system output, or any number of grouped outputs. Instructions for grouping outputs are provided in the Commercial Dimming System manual and are not included herein.The WP101K adds a key switch which can be used to disable the panel. Each WP101(K) 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 the required setup and wiring has been completed, the walllate may be mounted to a wall or other fixed structure.
