PRELIMINARY Wireless Accessory Doorbell Button SL-6190 Series The Heath/Zenith Wireless Accessory Doorbell Button works with existing U, V, W channel or Heath/Zenith jumper or dip switch doorbells. • Battery powered transmitter- No wires to run. • Channels are selectable to allow more than one doorbell set in the same house. © 2000 Heath Co., a Div. of DESA International595-5507-07 -2- 2. Set the doorbell button jumpers to match the chime receiver channel. This button works with channel U, V or W or jumper and dip switch receivers. The doorbell button is ready to use for channel "U". 1. Open the transmitter button case. Insert a flat blade screw driver into notch on bottom, push in on the tab, and twist the screwdriver. 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. -3- Set the jumpers 1 thru 7 to match the chime receiver. For receivers with switches: jumper on for switch up, jumper off for switch down. For channels V or W insert the jumpers shown below. For chimes with front and backdoor sounds, insert doorbell button jumper 8 for back door sound, remove jumper 8 for front door sound.

The button can be mounted by using the 2 holes in the back of the case, or double sided tape can be used. If the chime doesn't sound when you press the doorbell button, see page 6 for troubleshooting. 3. Before mounting, test the doorbell range by holding the button where you want to mount it and pressing the doorbell button. -5- Battery Replacement Remove back cover and old battery. Replace with an alkaline type A23 12 V battery. The positive terminal should be at the top of the case. Regulatory Information The user is cautioned that changes or modifica- tions not expressly approved by the party responsible for regulatory compliance could void the user's authority to operate the equipment. This device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. -6- Chime doesn't sound: • Make sure the doorbell button and the chime channels are the same (See page 3). • Check orientation of doorbell button battery. • Check the doorbell button and chime batteries, replace if necessary. Batteries are OK, but the chime doesn't work: • Don't mount the chime or doorbell button on metal or near metal studs. This reduces the transmitter range. Use 1/4" to 1/2" wood shims to move the chime or doorbell button off the metal surface. • Don't mount the chime too close to ground level concrete slabs. This may also reduce the range. Mount the chime away from the floor. • Try different locations for the chime closer to the doorbell button. Also try to orient the chime at a different angle to increase the range. The range of the doorbell depends on location, tempera- ture and battery condition. If you are having problems with this product, please try the solutions listed below.

Operational Description

Applicant: Heath Company, a Division of DESA International Inc. 2701 Industrial Dr. Bowling Green, KY. 42102 Manufacturing Location: Heath Company LTD. Rm. 704 Star Centre 443-451 Castle Peak Rd. Kwai Chung, Hong Kong Circuit Description The WB-94A-TX is a Wireless Remote Doorbell Transmitter designed to operate Heath Zenith door chimes receivers in the SL/CL series of AC (plug-in) or battery powered models. These wireless systems consist of the -615x, -616x, -617x and –618x series of products. The WB-94A-TX will also be packaged as a stand-lone accessory and case style may vary, including the push button that covers the power switch. A type-23A, 12V battery powers the transmitter and is included with the product. The transmitter is normally in a powered-down state (stand-by current is zero) until the operator presses a switch 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 12- volt supply (from the battery) is regulated to 5.6 volts by an integral regulator of a custom IC used to encode functions and control the “rf” generator stage. This custom IC is similar to the HT-12E encoder used in the previously certified version (SL-6194-TX) and produces a serial bit stream that corresponds to the state of its address and data control lines. The data rate is approximately 1 kHz 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 300 uS 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 jumper installed in a pin-header that is connected to the IC electrically sets the address and data control bits. When a jumper plug is not installed, 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 base of the “ rf” oscillator transistor, Q1 and is factory adjusted to 315 MHz by capacitor “VC”. The “rf” is activated when U1’s output is set at a logic high and deactivated when set at logic low. There is no external antenna, transmission radiation comes from a special PCB trace (circuit board foil) and a small internally mounted loop (L1). Alignment There are no user accessible adjustments. During manufacture, adjusting the tuning capacitor “VC” to 315 MHz sets the carrier frequency. Serv ice There are no user serviceable parts in this product. List of Generated Frequencies 315 MHz “rf” oscillator stage 120 kHz digital encoding stage Modulation: digital data, AM pulse-width coding.
