1. Giới thiệu
The KERUI Wireless Security Alarm System is a standalone siren alarm designed to protect your home, garage, barn, or any small property. It operates at 433MHz and does not require a GSM card, Wi-Fi, or a telephone line, making it a simple, effective, and portable security solution. The system features a loud 120dB siren to deter intruders and alert occupants.
This alarm system supports up to 40 wireless sensors, 10 remote controls, and 10 wireless doorbells. The effective wireless distance from sensors to the host system is approximately 50 meters, which may be reduced by physical barriers. The normal motion sensor can detect movement within 6 to 8 meters with a vertical angle of 60 degrees and a horizontal angle of 110 degrees.
When armed, if a door is opened by more than 1mm, or a PIR motion detector senses movement, the system will trigger an immediate alarm. Remote controls allow for easy arming and disarming. An 'S' button on the remote can be used to trigger a panic alarm, and a 'bell button' provides a doorbell function.
2. Thiết lập
2.1 Cài đặt ban đầu
The system comes pre-programmed. Before proceeding, ensure you wait for more than 6 seconds after plugging in the power adapter to allow the system to initialize.
- Door Sensors: Remove the back cover of the door sensors and insert the batteries, ensuring correct polarity (positive and negative sides). A light should illuminate briefly to indicate power. Install the door sensors using the provided two-sided tape.
- Infrared (PIR) Sensors: Attach all pieces of the infrared sensors together. Install them on any wall; drilling may be required for secure mounting.
2.2 Adding Remote Controls and Sensors
To program additional remote controls or sensors:
- Connect the siren host device to power. Wait for a loud beep sound and then wait for more than 6 seconds before proceeding.
- Unplug and plug the host device into and out of power 3 lần. The host will beep 3 times.
- After hearing the 3 beeps, press any button on the remote control. For a sensor, turn on its side switch or separate the magnetic stripe of a door sensor.
- The sensor will light up red, and you will hear beeps, indicating successful connection. You can then connect other remotes or sensors.
2.3 Adding Wireless Doorbell Buttons
To program a wireless doorbell button:
- Unplug and plug the host device into and out of power 7 lần. The host will beep 7 times.
- Press the doorbell button. You will hear beeps, confirming the connection.
2.4 Khôi phục cài đặt gốc
To reset all sensors and remote controls to factory settings (sensors cannot be deleted individually):
- Unplug and plug the host device into and out of power 10 lần.
- You will hear 10 beeps from the host. Wait for a while until the beeping stops.
- Once the reset is complete, you can proceed to set up all devices again.
3. Hướng dẫn vận hành
3.1 Kích hoạt và vô hiệu hóa hệ thống
- Cánh tay: Before leaving the protected area, press the 'lock button' on the remote control to arm the system. The siren will activate to protect your house.
- Giải trừ vũ khí: Before entering the protected area, press the 'unlock button' on the remote control to disarm the system.
3.2 Alarm Triggers and Response
When the system is armed, if any connected sensor (door sensor, PIR motion sensor, smoke detector, etc.) is triggered, the siren will sound loudly (greater than 100 dB) to deter intruders and attract attention. The alarm will typically sound for about 2 minutes and then stop automatically if not disarmed by the remote control.
3.3 Remote Control Functions (RC527)
Bộ điều khiển từ xa cho phép thực hiện nhiều chức năng khác nhau:
- Cánh tay: Activates the alarm system.
- Giải trừ vũ khí: Vô hiệu hóa hệ thống báo động.
- khẩn cấp: Triggers an immediate panic alarm.
- Chuông cửa: Activates the doorbell sound.
The remotes have sliding covers over the buttons to prevent accidental activation, but they do not have a waterproof function. They are powered by a 23A 12V battery. If the working distance decreases, it indicates the battery needs changing.
4. Bảo trì
4.1 Thay thế pin
- Cảm biến cửa: Requires 3 'AAA' batteries (not included). Replace when the sensor's indicator light does not flash or the system fails to detect it.
- Infrared (PIR) Sensor: Requires 1x 9V 6F22 battery (not included). Replace when the sensor's indicator light does not flash or the system fails to detect it.
- Máy dò khói: Requires 1x 9-Volt battery (not included). The detector has a low battery reminder feature. Replace the battery when indicated.
- Remote Control (RC527): Requires 1x 23A 12V battery. Replace when the working distance of the remote control decreases significantly.
Always ensure correct battery polarity when replacing.
KHAI THÁC. Xử lý sự cố
5.1 Các vấn đề thường gặp và giải pháp
- Siren not responding during programming: Do not plug and unplug the host too fast during programming sequences. The host needs sufficient time to detect power cycles. Ensure you wait for the beep sounds to finish and more than 6 seconds before proceeding to the next step.
- Cảm biến không kích hoạt báo động: Ensure the system is in the armed state. Sensors will only work when the host is armed. Check sensor batteries and ensure they are correctly installed. Verify the sensor is properly programmed to the host (refer to Section 2.2).
- Remote control range reduced: This indicates a low battery in the remote control. Replace the 23A 12V battery.
- Need to add more sensors/remotes than initially provided: The system supports up to 40 wireless sensors and 10 remote controllers. Follow the programming steps in Section 2.2 and 2.3 to add additional devices.
- Want to use one sensor with multiple sirens: Yes, one sensor can be programmed to work with two or more siren alarm hosts. This allows for placing sirens in different areas while being triggered by a single sensor.

7. Mẹo sử dụng
- Tăng sức mạnh ban đầu: Always wait for more than 6 seconds after plugging in the power adapter before attempting to program or operate the system. This ensures the host has fully initialized.
- Arming for Protection: Remember that sensors will only trigger an alarm when the host is in the armed state. If you do not need the accessories to work, disarm the system using the remote control.
- Khả năng mở rộng: This system is highly expandable. You can add more accessories or even multiple siren hosts. One sensor can be programmed to work with two or more siren alarm hosts, allowing you to place sirens in different areas for broader coverage.
- Programming Speed: When programming, avoid plugging and unplugging the host too quickly. The system needs time to register each power cycle.
