HBW1615Superregenerative Receiver

Univer sal Radio Contr ol OWNERS MANU AL With SECURITY : , the code between the remote control and the receiver changes with each use, accessing over 100 billionnew codes.You can activate your opener with several SECURITY : remote controls (with yellow indicator lights) utilizing up to 8 functions,and one SECURITY : Keyless Entry. Transformer Model 85 may be required if your garage dooropener is a brand other than Lift-Master, Chamberlain orSears.NOTE: Model 535-2LM is factory pre-set with matching receiver and remote control codes.IMPORTANT: For maximum security and range, you mustdisable the existing radio on your opener, otherwise itcould still activate your opener:• If there is an external receiver, disconnect power to it.• If it is an integrated receiver, either clip off the component that feeds power to the receiver or remove the tuning slug and antenna from the receiver section. • If you have a Lift-Master, Sears or Chamberlain opener with a“SMART” receiver, erase the old codes by holding down theSmart button for 6 seconds until the indicator light turns off. • If you have code switches, reset them to a random code and deactivate the receiver by removing the tuning slug andantenna. THE RECEIVER MAY BE INSTALLED IN ONE OF TWO WAYS:1. Mounted directly on the door opener with clips provided as shown on page one. 2. Attached to an inside wall of the garage with connecting bell wire (not supplied) as shown on page two. When installing two or more receivers in a garage, positionthem at least 10 feet apart to prevent electronic interference.MOUNTING RECEIVER ON A COMMERCIAL OPENERFully extend antenna wire below bottom of case as shown.Loosen the three terminal screws on the receiver (labeled 1, 2and 3). Insert one end of a mounting clip under each terminal. Do not retighten at this time.Loosen the three terminal screws on the opener used for pushbutton controls and radio power.Leaving the push button bell wire in place, insert the other endsof the mounting clips under the opener terminal screws.NOTE: If the number sequence of opener terminalsdoesn't match the receiver, turn the receiver around (soback is facing out) and complete the connection.Retighten the terminal screws on opener and receiver.Reconnect power to the opener. The receiver push bar shouldlight. If it does not, use Transformer Model 85. Model 535LM Security : Receiver Onl y Model 535-2LM Security : (With 2 Remote Contr ols) MOUNTING ON RESIDENTIAL OPENERSUse a 2 wire connection only. Attach mounting clips to receiver terminals 1 and 2, and to the opener terminals used for pushbutton controls. Plug the transformer into the receiver asshown, and into a 120 Volt outlet. Side two contains wall mounting instructions and code setting instructions. Children operating or playing with a garage dooropener can injure themselves and others. The garage door could close and cause serious injury or death. Do not allow children to operate the push buttons or theremote control transmitters.Install the receiver (and any additional push buttons)out of the reach of children and away from all movingparts of the door and door hardware, but where the garage door is visible. A moving garage door could injure someone under it. Activate the opener only when the door is properlyadjusted, you can see it clearly, and there are noobstructions to door travel.

The final instruction sheet is not available at this time, so I have included a typical instruction sheet indicating the FCC statement and important information. The FCC ID of this model, upon certification, will be HBW1615. We would appreciate your prompt attention to the submittal. Sincerely, THE CHAMBERLAIN GROUP, INC. Barbara P.

Operating Instructions 7. Test Report EXPOSITORY STATEMENT Super-regenerative Receiver Model 535-315LM 1. Since the final instruction sheet is not available at this time, a typical draft version has been included. The instructions include statements required to assure compliance with the Commission's Rules; Part 15. 2. Labeling is in accordance with the Commission's labeling requirements, Parts 2 and 15, Section 15.19. 3. This receiver is intended for use with certified transmitters of our manufacture only. 4. The 535-315LM receiver is factory set to 315 ± 0.1% MHz. It is not intended to be readjusted in the field, and specific instructions prohibiting tampering are provided to the user. 5. Test data for Model 535-315LM is part of this submission. No emissions were detected in the forbidden bands below 1.0 GHz. Certified by: Barbara P. Kelkhoff Manager, Regulatory Affairs THEORY OF OPERATION AND CIRCUIT DESCRIPTION MODEL 535-315LM REMOTE CONTROL RADIO RECEIVER Please refer to enclosed schematic 195D1615 The radio uses the analog input into an external comparator, which converts the signal to digital for input to digital radio in. The radio signal comes in at any signal level from 10mV to approximately 3V of swing with a D.C. point of 2.5V. This input is avg. detected by R20 and C17 which is fed into one side of the comparator while the undetected signal is fed into the other. Diode D1 is used for overload protection of the comparator. R21 is used to compensate for the change in duty cycle of the radio signal due to different pulse widths. MOSFET Q3 provides extra noise immunity during the radio blank periods. Normally, the active clamp on the micro-controller turns on Q3, causing the MOSFET to appear as a small resistor to the rest of the circuit. When a valid radio code word is detected, the active clamp is set low, turning the MOSFET off. This causes the MOSFET to appear as an open circuit, and holds the voltage across C17 at a constant level. This ensures that the reference voltage does not drift toward the noise floor during a radio reception. The MOSFET is again turned on at the end of the radio word, when a radio error occurs, or when 500ms have passed without any radio signal. The learn switch is used to place the unit into learn mode by monitoring pin 6. When the switch is pressed, learn mode is set and the LED on pin 18 is turned on. If the switch is held active for more then 6 seconds the memory will be erased and the learn mode will be cleared. If while the unit is in learn mode a radio code is properly received twice then that code is placed in memory (if not already there), and the learn mode is cleared. If within 30 seconds the learn mode is not cleared the learn mode will time out and be cleared. The switch on pin 6 is the command input and acts like a radio code being received as long as the switch is held. This switch is debounced with a debounce time of 80mS±10mS. The switches are read by the micro-controller (U2) setting the input pins 6 and 8 into the input mode. R29 and R30 are needed to limit the current when S1 or S2 is active. R38 is for limiting the LED current. R31 and R32 are for limiting the ESD current. The active clamp signal is generated on pin 9. Upon receiving a valid Chamberlain code, the circuit “clamps” down on the signal, doing an average detection of the incoming signal. This improves the range of the radio reception, and allows better “filtering” of noise spikes to improve radio performance. The oscillator pins 15 and 16 are used for the main clock generation. These pins will have a ceramic resonator connected between them to generate the 4.0 MHz main clock frequency. 1. EXPOSITORY STATEMENT 2. THEORY OF OPERATION 3. SCHEMATIC 4. PHOTOGRAPHS 5.
