RS04B RECESSED CEILING MICROWAVE SENSOR SWITCH

The RS04B microwave sensor switch uses 5.8GHz Radar waves. It detects human movement and body heat when a person enters the device’s sensing area. The light will automatically turn on and remain on while movement is detected. It automatically turns off when no one is present or when the person moves out of the sensing area. The microwave sensor is not affected by ambient temperatures above 32°C. It is highly sensitive and can detect through obstacles such as wooden partitions, glass, thin walls, plasterboard, and more. The device features a compact design and is very convenient for recessed ceiling installation. In particular, the cover can slide up and down to access the adjustment knobs on the sensor. This helps improve the aesthetics of the installation space. It is suitable for installation in large areas with internal partitions such as public restrooms, fitting rooms, garages, staircases, balconies, and more.

MICROWAVE SENSOR SWITCH WITH 3 CONVENIENT ADJUSTMENT KNOBS

The RS04B Radar Sensor Switch is equipped with 3 adjustment knobs: SENS, LUX, and TIME:

• SENS: Adjusts the detection distance. The minimum adjustable distance is 2m “–”, while the maximum adjustable distance is 8m “+”.
• LUX: Adjusts the ambient light level at which the sensor activates. When the arrow points to 3 Lux (equivalent to around 7–8 PM), the sensor only turns on when the surrounding environment is completely dark. When the arrow points toward the sun symbol, the sensor operates both during the day and at night. The light level can also be adjusted from 3–2,000 Lux.
• TIME: Adjusts the automatic switch-off delay when no movement is detected within the sensing area, from 10 seconds to 12 minutes.

Note: When testing under daylight conditions, please turn the LUX knob to the sun symbol position. Otherwise, the sensor light will not operate.

WHERE IS THE RADAR SENSOR LIGHT SWITCH COMMONLY INSTALLED?

With its strong ability to detect through obstacles and long sensing distance, the Smart Switch is commonly installed in large spaces with many obstacles, such as:

• Public areas with multiple partitions: restrooms, fitting rooms, and more.

• Hallways, balconies, and large restrooms in apartment buildings, hotels, hospitals, villas, and more.
• Tunnel lights, apartment emergency exits, parking areas, warehouses, workshops, garages, and more.

BENEFITS OF USING A SMART SENSOR SWITCH

• Effectively saves electricity by preventing lights from being left on continuously.
• Reduces maintenance costs and the cost of purchasing and replacing light bulbs: The lighting system can rest when no one is present. This can increase lamp life by up to 50% and reduce annual maintenance costs.
• Improves user safety, especially in homes with elderly people and children. There is no need to manually turn lights ON/OFF, helping reduce the risk of electric shock.
• Unlike infrared sensors, which are often affected by high temperatures and cannot detect through obstacles, the RS04B radar sensor is more suitable for large areas. It can help reduce the need to install multiple sensors because microwave sensing overcomes many limitations of infrared sensors.
• Provides an additional anti-theft solution. When installed at gates, walkways, rear hallways, balconies, and similar locations, the light can automatically turn on when an intruder enters, which may help deter theft.

SƠ ĐỒ NỐI DÂY

• Đẩy nắp nhựa lên và điều chỉnh trên các nút Lux, Time, Sens để phù hợp với nhu cầu.
• Tháo nắp nhựa trong suốt ở phía dưới, nới lỏng các vít ở đầu kết nối. Sau đó, nối dây nguồn và dây ra đèn theo sơ đồ hướng dẫn.
• Gập lò xo kim loại của cảm biến lên phía trên, cho đến khi chúng ở vị trí chữ “I” với cảm biến. Sau đó đặt công tắc cảm biến vào lỗ khoét, có kích thước tương đương. Nhả lò xo, công tắc cảm biến sẽ được cố định ở vị trí cài đặt này.
• Sau khi cài đặt xong bật nguồn, kiểm tra thiết bị.

MỘT SỐ VẤN ĐỀ THƯỞNG XẢY RA VÀ CÁCH XỬ LÝ

• Nguồn ra không hoạt động:

1. Kiểm tra nguồn ra và nguồn vào
2. Đèn báo có được bật sau khi công tắc cảm biến không? Nếu có, vui lòng kiểm tra nguồn.
3. Nếu đèn không sáng sau khi công tắc cảm biến, kiểm tra xem bóng đèn hoạt động có tương ứng với ánh sáng đã cài ở nút Lux không?
4. Vui lòng kiểm tra xem điện áp có tương ứng với nguồn điện không.

• Poor sensitivity:

1. Vui lòng kiểm tra xem phía trước cảm biến, có vật cản nào ảnh hưởng đến việc nhận tín hiệu hay không?
2. Vui lòng kiểm tra nút Sens xem khoảng cách cảm biến có chỉnh về mức thấp nhất không?
3. Vui lòng kiểm tra chiều cao lắp đặt, có phù hợp với khuyến cáo từ nhà cung cấp không?

• Cảm biến không thể tự ngắt tải:

1. Nếu có tín hiệu chuyển động liên tục trong các trường phát hiện
2. Nếu thời gian trễ Time được chỉnh thành dài nhất​
