WHAT IS A WIRELESS DOORBELL?

Chuông cửa không dây là thiết bị báo hiệu có khách hoặc có người ở ngoài cần vào nhà. Ngày nay nhà ở được xây tầng nhiều và kín nên khó có thể kêu bằng miệng hoặc dùng chuông cửa có dây. Lúc này, sẽ bị hạn chế nếu người trong nhà ở gần cổng thì có thể nghe nhưng nếu ở tầng cao thì khó nghe được.

Vì thế….

The B8A Doorbell Wireless doorbells have become increasingly popular because they eliminate the need for complicated wiring. Their compact design makes them easy to install, relocate, and use in a wide range of locations.

OUTSTANDING FEATURES OF THE WIRELESS DOORBELL

• The wireless doorbell operates by transmitting signals through radio waves without requiring signal wires. The operating range is approximately 20–70 m. The 433MHz RF frequency can transmit through walls, allowing the doorbell to operate effectively.
• The chime volume can be adjusted according to household needs. There are 3 selectable volume levels: High / Medium / Low. The KAWASAN wireless doorbell also provides up to 32 preset chime melodies, allowing users to select and change the ringtone according to their preferences.

• The doorbell push button is powered by a small 12V 23A battery. Its low power consumption helps extend battery life. The chime receiver operates on a 110–240VAC power supply, providing convenient and energy-efficient operation. The wireless doorbell also offers good water resistance with an IP44 protection rating.

APPLICATIONS OF THE WATER-RESISTANT WIRELESS DOORBELL IN DAILY LIFE

• Used as a doorbell

• Used as an emergency alarm call button
• Used as an assistance call system for elderly users

• Used as a visitor chime or service call system

• Used as an internal call chime in homes, offices, hotels, and similar facilities

BENEFITS OF USING A WIRELESS ELECTRIC DOORBELL

• Flexibility: The chime receiver can be easily relocated and installed in different areas of the house, such as living rooms, stairways, corridors, or different floors. The push button can be mounted on a door, wall, gate, or entrance.
• Improved aesthetics: No signal wiring is required between the doorbell push button and the chime receiver, helping reduce installation work and maintain a cleaner appearance.
• No renovation required for installation: Many house façades are finished with granite or decorative stone, which is difficult to drill. Homeowners may also prefer not to drill because doing so could damage or crack the stone surface. If wiring is required only to install a single push button, a wireless push button is a more suitable option.
• Convenient battery replacement: The wireless push button uses a replaceable battery that typically lasts around 6 months. The chime receiver can be plugged directly into a 220V power outlet.
• Expandable system: In large or multi-story homes, a single chime receiver may not be audible everywhere. KAWASAN wireless doorbell push buttons and chime receivers can be expanded and paired with additional units as needed.

For example:

Nhà có 2 cửa và 3 tầng nếu dùng 1 chuông cửa thông thường. Bạn phải dùng 3 bộ chuông gắn cho 3 tầng, nút nhấn phải gắn 3 cái ở cổng để gọi từng tầng. Với chuông KAWASAN bạn chỉ cần 1 nút nhấn với 3 đầu phát chuông cắm vào ổ điện tại mỗi tầng. Với nút nhấn gắn tại cửa hoặc cổng tiện lợi. Khi nhấn 1 nút nhấn thì 3 chuông đều phát nhạc.

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.

COMMON PROBLEMS WHEN BUYING LOW-QUALITY WIRELESS DOORBELLS

• Short signal transmission range of only approximately 10–15m. When installed in multi-story buildings, pressing the push button may fail to activate the chime on higher floors.
• Low-quality push buttons with poor water resistance may fail after a short period of outdoor use.
• Limited or no expansion capability, requiring users to purchase additional complete doorbell sets for other areas of the house, especially in multi-story homes.
• Low initial purchase price but poor durability of less than 2 years, resulting in higher replacement and repair costs over time.

WHY SHOULD YOU CHOOSE A KAWASAN WIRELESS DOORBELL?

• Kawasan is an established brand in the doorbell and visitor chime. The products come with a 2-year warranty, and the product service life is guaranteed to be more than 5 years. Customers are also supported by a professional sales consulting team and timely technical assistance.
• The operating range of the wireless doorbell has been improved. 433MHz RF transmission technology provides strong signal transmission from the push button to the chime receiver, where the ringtone is generated. The chime can be heard throughout the house, with a signal transmission range of approximately 20–70 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.
• Independent RF receiving channel: With this feature, your wireless doorbell will not interfere with your neighbor's doorbell. Each system is paired using a separate coded channel, helping prevent situations where pressing your push button causes your neighbor's chime to ring, or vice versa.
