The doorbell can be heard throughout the house, with a signal transmission range of approximately 40–80 m.
- Expandable pairing capability provides greater convenience for large and multi-storey houses. One KAWASAN doorbell receiver can be paired with up to 4 push buttons, while one push button can be paired with multiple chime receivers. This helps homeowners avoid the additional cost of purchasing a complete doorbell set with one receiver and one push button for every area of the house.

- Product specifications are clearly printed on the packaging for easy reference and operation. Long product service life helps reduce replacement costs over time.

WHEN SHOULD A WATERPROOF WIRELESS DOORBELL BE USED?

- For households and apartments with young children or elderly people: When elderly family members or young children need assistance, they can press the button to call someone without having to shout loudly or spend time moving around.

- For multi-storey houses and villas: It helps save time spent moving between floors and rooms to call someone. At the same time, occupants can hear the doorbell when a visitor presses the button at the entrance.

- Uses service call stores, showrooms, restaurants, hotels, guesthouses, hospitals, etc. It helps save time when calling service staff, nurses, receptionists, and others.

BENEFITS OF USING A WIRELESS ELECTRIC DOORBELL
- Flexibility: The chime receiver can be easily moved and installed in different locations throughout the house. It can be plugged into power outlets in the living room, stairway, hallway, or on different floors. The push button can be installed on a door, attached to a wall outside the gate, or positioned near the entrance.
- Maintains aesthetics: There is no need to run electrical wires to the push button, helping reduce wiring and installation costs while maintaining the appearance of the house.
- No renovation required for installation: House façades are often finished with granite or other decorative stone surfaces that are difficult to drill. Homeowners may also prefer not to drill because doing so could damage or crack the stone. Installing wiring simply for one doorbell button can therefore be inconvenient. In such cases, a wireless push button is a suitable choice.
- Battery-free wireless doorbell push button: The push button generates the required energy when pressed and transmits the signal to the chime receiver. The chime receiver can be plugged directly into a 220V power outlet.
- Expandable pairing capability: In large houses with multiple floors and entrances, a single chime receiver may be difficult to hear throughout the entire property. KAWASAN wireless doorbells allow both the push button and chime receiver system to be expanded by pairing additional devices.

CÁC VẤN ĐỀ THƯỜNG GẶP
-
Khoảng cách từ nút nhấn chuông đến chuông không đủ xa, phải làm sao?
Trả lời:
a/ Tránh lắp chuông gần vị trí có sóng Radio, sóng wifi hoặc nơi có nhiều kim loại
b/ Tránh lắp vị trí có tường bê tông, vách kim loại ngăn cách, làm hạn chế khả năng phát sóng
c/ Di chuyển vị trí để chuông ra vị trí gần cầu thang, hoặc gần ban công để chuông có thể dễ dàng nhận sóng từ nút nhấn.
d/ Tránh lắp nút nhấn trực tiếp vào cửa sắt, vách sắt hoặc kim loại, làm hút sóng, không phát đi xa được, cần có tấm gỗ, nhựa ngăn cách giữa đến nút nhấn và vách kim loại.
e/ Hoặc phải chuyển qua dùng loại chuông dùng Pin để nguồn điện mạnh hơn để có thể phát sóng mạnh hơn.
-
Vì sao bấm nút nhấn chuông nhẹ chuông không kêu mà phải bấm hơi mạnh tay?
Trả lời: Vì dùng công nghệ dùng lực bấm tay để tạo lực phát điện, vì vậy nếu người bấm chuông bấm quá nhẹ, không đủ điện phát sóng đi đến chuông.
-
Vì sao tích hợp nút nhấn với chuông không được.
Trả lời:
a/ Chú ý kiểm tra xem gần đó có thiết bị phát sóng Radio nào đang phát không thì tắt đi. Ví dụ như đầu báo khách D28B đang hoạt động thì tắt đi, hoặc có ai đó bấm giữ nút nhấn chuông khác hoặc có vật đè lên Remote phát sóng Radio, làm phá sóng, không tích hợp vào được.
b/ Kiểm tra xem chuông đã nhận hết 4 nút nhấn chưa, vì nếu nhận hết 4 nút nhấn sẽ không nhận thêm vào được.
c/ Hoặc có thể do người bán đã tích hợp thử nhiều nút nhấn vào, lúc này phải bấm Reset, xóa tất cả các nút nhấn đã học vào trước đó đi, sau đó tích hợp lại.
-
Vì sao chuông không kêu:
Trả lời:
a/ Kiểm tra lại xem ổ cắm nguồn vào có bị lỏng tiếp xúc bên trong không! Cắm thử vào ổ điện khác
b/ Kiểm tra xem nút nhấn âm lượng đã bật lên mức cao chưa?
-
Vì sao khi đóng cửa sắt, cửa cuốn vào thì bấm chuông không kêu?
Trả lời:
a/ Cửa kim loại làm hạn chế khả năng phát sóng và nhận sóng. Vì vậy cần di chuyển chuông ra vị trí ổ cắm sát cửa để dễ nhận sóng.
b/ Nếu sau khi dời vị trí chuông gần cửa hơn mà vẫn không kêu. Cần thay thế loại chuông cửa không dây dùng Pin DB668B hoặc BD669 để giúp phát sóng mạnh hơn và xa hơn.

“ Attention: Vì dùng công nghệ tự sinh từ trường nên sóng RF yếu hơn loại dùng Pin, có thể không xuyên qua được vật cả là cửa sắt, cửa cuốn, trần bê tông dầy…”
- Cài đặt thêm được nhiều chuông và nút nhấn
- Cách cài đặt thêm chuông hoặc nút nhấn:
- Nhấn giữ nút chọn kiểu chuông 5~8 giây, phát ra 2 tiếng đing đing thì nhấn nút nhấn chuông sẽ có 1 tiếng đing phát ra có nghĩa 2 thiết bị đã nhận nhau, chờ khoảng 5 giây sẽ phát ra 2 tiếng đing là thành công.
- Để xóa nút nhấn chuông, rút điện ở phần chuông ra. Nhấn và giữ luôn nốt nhạc trên chuông, đồng thời cắm vào nguồn điện chờ khởi động 8 giây là xóa thành công.

For example, consider a house with 2 entrances and 3 floors. With a conventional doorbell system, you may need to install 3 separate doorbell sets for the 3 floors, with three push buttons at the gate to call each floor separately. With a KAWASAN wireless doorbell, you only need 1 push button and 3 chime receivers, with one chime receiver plugged into a power outlet on each floor. The push button is installed at the door or gate. When the button is pressed once, all 3 chime receivers will ring simultaneously.

With a wired doorbell, this arrangement is more difficult because additional wiring is required, and once installed, the devices are fixed in position and are difficult to relocate.
