DRAFT COPY 3-WAY WALL SWITCH TRANSMITTER DIM DIM Important: This product should be used in conjunction with the Wall Switch Receiver. 3-way circuit wiring is required to install and use this product. Note: If you are not familiar with electrical wiring, consult an electrician about installation. In addition, some local building codes may require installation by a qualified electrician. Installation 1. Select light switch to be replaced by 3-way wall switch transmitter. 2.Turn off the power to the light switch circuit before you proceed. Do this at your circuit breaker or fuse box. 3. Remove the existing wall plate and switch. Label the wires on the existing switch according to the diagram in Figure 1. Note: Typical 3-way wiring is shown. Actual wiring may vary. WHITE FROM POWER SOURCE WHITE (Neutral)WHITE 1 BLACK (Hot) GREEN (Ground) 2 RED 4 BLACK 3 BLACK Figure 1 (Typical 3-Way Wiring Shown) 4. Disconnect the two power wires and the ground wire. 5. Connect the wires of the 3-way wall switch transmit- ter and wall switch receiver to the wires in the junction box as shown in Figure 2. Use the supplied wire connectors to secure the wires (see Figure 2). Note: Either black wire on the transmitter and receiver can be used to connect to the hot wire. 6. Connect the green ground wire from transmitter to the ground wire removed from old switch. Use one of the supplied wire connectors to secure the wires (see Figure 3). 7. Check wire connections to make sure they are se- cure and that no bare wires are exposed. 8. Position the wall switch transmitter in the junction box with the DIM button located to the right. Use the two wall switch screws (long) supplied to mount the receiver to the junction box (see Figure 3). Push excess wiring into junction box while you do this, bending the wires to fit if necessary.

DRAFT COPY Operation 1. Verify the power disconnect switch on the transmitter and receiver is in the ON (right side) position. 2. Push the ON (top) button and release. The light should turn on full bright. Note: If you are controlling a lamp, make sure it is connected to the switched outlet and the lamp is switched on. 3. Push the OFF (bottom) button and release. The light should turn off. 4.Push the DIM button and release. The light should turn on at 50% brightness (or last setting). Note: Receiver remembers the last DIM setting used. To recall last DIM setting, push and release the DIM button. 5. Continue to press the DIM button until the desired dim level is reached. Note: There are 5 DIM settings ranging from 15% to 90% brightness. Note: The DIM setting defaults to 50% in the event of a power failure. Important: Wait 1 to 2 seconds after you press a trans- mitter button before you press it again to allow the transmission to be completed. Note: If light does not turn on or intermittently turns on and off when transmitter buttons are pushed, see Trouble- shooting Guide. Bulb Replacement Move the power disconnect switch on the transmitter and receiver to the OFF (left side) position. Replace bulb(s). Note: The power disconnect switch on the transmitter prevents the unit from sending any signals to the re- ceiver. The power disconnect switch on the receiver prevents it from applying power to the load that it controls.

DESA International 6/4/2003 Confidential 6023-TX AC Wireless Wall Transmitter AC Wireless Wall Transmitter Model Number: 6023-TX General Description: The 6023-TX AC Wireless Wall Transmitter is a transmitting device used for remotely controlling room lights by utilizing RF transmission technology and a compatible RF receiving device. The device is capable of transmitting three separate commands, which are used by the compatible receiver to turn the room lights ON or OFF or to dim the lights. The housing, front cover, and pushbuttons are made of an ABS plastic (PA765A) and the mounting plate is made of 16 gauge sheet metal. The assembly is designed to mount to a standard single-gang junction box. The electrical circuitry is comprised of a 5-Volt DC power supply, 3 tact switches, one 4- position dipswitch, a CMOS 12-bit encoder IC, a 315 MHz RF oscillator circuit, and complementary passive components. The power supply is a half-wave rectifier with voltage-dropping resistor/capacitor and 5-volt regulator. The power supply circuitry is located on the rear circuit board and the RF and encoder circuitry is located on the front circuit board. The two boards are connected together with a ribbon cable. The printed circuit boards are double-sided and have a 94V-0 rating. Specifications: • Input: 120 VAC, 60 Hz • Circuit voltage: ~5.0 volts DC. • RF Carrier Frequency: 315 MHz • Modulated Data Frequency: 3.0 KHz • User-selectable address codes: 16 Theory of Operation: The wireless transmitter is normally off with the RF transmission starting when one of the pushbuttons is depressed momentarily. When one of the three normally open pushbuttons is depressed, the 5-volt power supply output is connected to the encoder IC and RF circuitry. When the circuit is completed, the encoder outputs a 3 KHz 12-bit transmission to the RF oscillator circuit transmitting the information at a carrier frequency of 315 MHz. The encoder continues to transmit as long as the pushbutton is depressed. The 12-bit output consists of an 8-bit address and 4 bits of data. The user-selectable address is set with a four-position dipswitch. The other 4 address lines are permanently set. The receiving unit to be controlled is set to the same address as the wireless transmitter. DESA International 6/4/2003 Confidential 6023-TX AC Wireless Wall Transmitter Theory of Operation (continued) The wireless switch is capable of sending 3 different commands to a compatible receiver. It can transmit an ON, OFF, and DIM code. When the ON, OFF, or DIM switch is depressed, the corresponding data bit is pulled low (connected to ground via the tact switch). When the receiving unit receives and decodes the signal, it executes the desired ON, OFF, or DIM operation.
