BJ4-62WDB93TXWireless Remote Doorbell Transmitter

Brass Transmitter Wireless Push Button Accessory The Heath ® /Zenith Wireless Push Button Acces- sory works with existing Heath ® /Zenith jumper or dip switch systems. • Battery powered push button - No wires to run. • 128 selectable codes allow more than one chime system in the same house. © 2001 DESA International598-1105-00 SL-6293/94/95 Brass Transmitter Series (Style may vary from illustration) -2- 598-1105-00 2.Set the push button dip switches to match the chime receiver code. See "Code and Tune Setting" section. 1.Install two lithium type CR1220 3 volt push button batteries (included). Re- move back of case by pushing in tab on bottom with a small screwdriver. Make sure batteries are oriented prop- erly (see page 6). 4. Mount push button. Remove back of case by pushing in tab on bottom with a small screwdriver. Attach back of case to door jamb or wall with screws provided. Snap front of push button on. 3.Test range. Temporarily position push button where you want it mounted. Press push button to verify chime and push button work properly. If chime does not sound, see Troubleshooting. -3- 598-1105-00 Code and Tune Settings Code Settings Note: Most installations will not require you to change any jump- ers or dip switch settings on your chime and push button. WARNING: Disconnect chime unit from power source be- fore opening code access door. Close door and replace screw before reconnecting to power. The push button and chime communicate by using a code that can be changed by switching dip switch positions (or removing and/or adding jumpers) on both the push button and chime. The code is factory set; however, there are 128 selectable codes that allow you to expand your system and prevent outside inter- ference. Other wireless products may cause interference and the system may not function properly. Follow the instructions below for setting a new code. 1. Unplug wireless chime (if applicable). 2. Open the cases and locate the jumpers or dip switches on both the push button and chime (See illustration on page 6). 3. The push button and chime both have eight different jumper/ dip switch locations. Positions 1 through 7 are used for set- ting the code. 4. To change the code, add and/or remove jumpers or change dip switch setting as needed. It is recommended to only change one setting at a time and then check to see if system -4- 598-1105-00 is functioning properly. Note: Positions 1 through 7 must be exactly the same for both the push button and chime for this system to function. Tune Settings Your Heath ® /Zenith wireless chime has different selectable tunes: Ding (one note), Ding-Dong (two note), or Westminster (eight note) (Available on selected Heath ® /Zenith chimes). The fac- tory setting is for the Ding-Dong tune (or Westminster, when available). This tune can be changed by following the instruc- tions below. •Ding (one note tune) Push button: Location 8, Add jumper or set dip switch high (1 or ON). •Ding-Dong (two note tune) Push button: Location 8, Remove jumper or set dip switch low (0 or OFF). Chime: Remove jumper from location 8. •Westminster (Eight note tune) (Available on selected Heath ® / Zenith chimes) Push button: Location 8, Remove jumper or set dip switch low (0 or OFF). Chime: Add a jumper to location 8. -5- 598-1105-00 Note: All models have both front and back door tune capabili- ties. You may purchase any Heath ® /Zenith wireless push button for a second entrance. We recommend the back door use the Ding tune and the front door use the Ding-Dong tune (or Westminster tune, available on selected Heath ® /Zenith chimes). Models that include two push buttons will come factory set for front and back doors. Decals on the rear of the push button will indicate its setting. -6- 598-1105-00 1 2 3 4 5 6 7 8 ON 12345678 Inside Push Button Replacing Push Button Batteries Install two lithium type CR1220 3 volt batteries.

Heath ® /Zenith reserves the right to discontinue and to change specifications at any time without notice without incurring any obligation to incorporate new features in previously sold products. (+) Positive Battery Terminal -7- 598-1105-00 Troubleshooting Chime doesn't sound: •Make sure push button and chime codes are the same (See pages 3 through 6). •Check orientation of push button batteries (See page 6). •Check charge of push button and chime batteries (if applicable), re- place if necessary. Batteries seem OK, but the chime doesn't work when installed: •Don't mount chime or push button on metal or near metal studs. This reduces the transmitter range. Use 1/4" to 1/2" (6 to 13 mm) wood shims to move chime or push button off metal surface. •Concrete floors may reduce range. Move chime away from floor. •Try locating chime closer to push button. The range of the wireless chime can vary with location, temperature and battery condition.

Applicant: DESA International Inc. 2901 Industrial Drive Bowling Green, KY. 42102 Manufacturing Location: Heath Company LTD. Rm. 704-5 Star Centre 443-451 Castle Peak Road Kwai Chung, Hong Kong Circuit Description The WB-SAW-TX is a Wireless Remote Doorbell Transmitter designed to operate all Heath®/Zenith door chime receivers in the SL (or private label) series of AC (plug-in) or battery powered models. These wireless systems consist of the –615x, -616x, -617x, - 618x, -625x, and –628x series of products. The WB-SAW-TX will also be packaged as a stand-alone accessory and case style may vary depending on actual model. Two type CR-1220, 3V (6V total) batteries power the transmitter and are included with the product. The transmitter is normally in a powered-down state (zero stand-by current) until the operator presses the switch (push button) to activate the unit. This switch is a front cover push button (momentary contact) that supplies power to the circuit as long as the button is pressed. When the button is released, power is removed and the transmission is stopped. The 6-volt supply from the battery is regulated to 4.4vots by an internal regulator of a custom IC used to encode functions and control the “rf” generator stage. This custom IC (444-P008) is the same custom chip that was used in the previously certified transmitters (WB-94A-TX and WB-97-TX). This IC produces a serial bit stream that corresponds to the state of its address and data control lines. The data rate is approximately 1kHz and the pattern consists of 8 address bits, 4 data bits, and 1 “start” bit (a 13 bit information block). The logic data high bit (one) is represented by a 600 uS pulse-width and a logic low bit (zero) by a 300uS pulse-width. A minimum of four 13- bit information blocks are sent (transmitted) each time the push button is pressed and will repeat while the switch is held down. A surface mounted mini dipswitch that is connected to the IC electrically sets the address and data control bits. When a switch is set to “0” or “OFF”, the data line floats (pulled high by the internal structure of the IC) and the bit is set at a logic zero. The output of the custom encoder IC (U1) drives the “rf” oscillator Q1, frequency stabilized with a SAW (Surface Acoustical Wave) Resonator operating at 315 MHz. The “rf” is activated when U1’s output is set at logic high and deactivated when set at logic low. Transmission radiation comes from a small helical antenna that is mounted directly to the PCB and is located completely internal to the transmitter housing. Alignment There are no user adjustments. The design and use of the SAW resonator locks the carrier frequency to 315 MHz. Service There are no user serviceable parts in this product.
