ABC Auctions YL-191 Wireless Alarm System
Product Usage Instructions
- Part A: RF ET15 433MHz
- RF frequency emission part ET15 is a 433MHz FM transmitter chip. The working frequency is set to 13.560MHz. The main control MCU 815T-SOP8 sends the protocol to ET15 through the data pin based on the presence of human infrared, sending the radio frequency through the high-frequency matching circuit.
- Part B: ET15 RF Emission Display Section
- When the main control chip detects human infrared, it sends an RF command protocol to ET15 for emission.
- Part C: PIR MCU Infrared Identification Section
- The PIR detects human body movement and changes the level of the MCU port accordingly.
- Part D: MCU 815T-SOP8 MCU RF Main Control Chip Part
- The MCU enters sleep mode when no human infrared is detected to save power. It wakes up immediately upon detecting human infrared and sends RF command protocols.
- FCC Caution:
- RF warning for Mobile device: This equipment complies with FCC radiation exposure limits for an uncontrolled environment. Maintain a minimum distance of 20cm between the radiator and your body during installation and operation.
FAQs
- Q: How do I adjust the sound level on the receiver?
- A: The receiver has a sound level switch that allows you to select between a loud or weak alarm. Simply toggle the switch to your desired setting.
- Q: What should I do if the receiver ignores a repeated signal on the same channel?
- A: If a repeat signal is detected on the same channel within one hour, the receiver will ignore it. Ensure that no obstructions or interference are causing the repeated signal, and consider adjusting the position of your detector for optimal performance.
INTRODUCTION
- When the receiver gets a wireless signal from one detector, the channel indicator LED will light for 1 hour.
- And the alarm sound started for 1 minute.
- Sound once for channel 1 and twice for channel 2 until channel 5.
- If a repeat signal is detected on the same channel in one hour. the signal will be ignored.
- The receiver has a sound level switch to select a loud or weak alarm.

RF frequency emission part
ET15 is a 433MHz FM transmitter chip, the working frequency is set to 13.560MHZ when the main control MCU 815T-SOP8 sends the protocol to ET15 through the data in according to the presence or absence of human infrared and then sends the radio frequency through the high-frequency matching circuit.
Emission display section
When the main control chip recognizes the presence of human infrared, it will send an RF command protocol to the ET15.
Infrared identification section
- When a human body passes through, the PIR will change the level of the MCUport accordingly.
The main control chip part
- The MCU 815T-SOP8 will enter sleep mode when it does not recognize the infraredrays of the human body to save power, and when there are infrared rays of the human body, the MCU will wake up immediately and send RF command protocols.
FCC
FCC Caution.
& 15.19 Labelling requirements. This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
- This device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation.
15.21 Changes or modification warning
Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
15.105 Information to the user.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, under part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used per the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and the receiver.
- Connect the equipment into an outlet on a circuit different from that to which thereceiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
RF warning for Mobile devices:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
a minimum distance of 20cm between the radiator & your body.
