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….

wireless doorbells have become increasingly popular and widely used. They are convenient because they do not require complicated wiring, feature compact designs, are easy to install and relocate, and are available in various models.

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 20–40 m, depending on the RF environment and obstacles. The 433MHz RF frequency can transmit through walls, allowing the doorbell to continue operating effectively.
• The chime volume can be adjusted according to household needs. There are 4 selectable volume levels.

• The KAWASAN wireless doorbell comes with up to 32 preset chime melodies, allowing users to freely select and change the ringtone.
• The wireless push button is powered by a 12V 23A battery. Its low power consumption helps extend battery life. The chime receiver operates on 110–240VAC, providing convenient and energy-efficient operation.

• The push button is water-resistant and provides good protection against water ingress with an IP44 protection rating.
• The system can be integrated with the RM4A remote control to turn the chime on or off, change the ringtone, and increase or decrease the volume remotely.

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 locations.

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 pairing capability: In large houses with multiple floors and entrances, one chime receiver may be difficult to hear throughout the entire property. KAWASAN wireless doorbells allow additional push buttons and chime receivers to be paired with the system. One chime receiver can be paired with up to 4 push buttons, while one push button can be paired with multiple chime receivers.

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.
• An outstanding feature is its ability to integrate with the RM4A remote control, sensor units, and magnetic door sensors.
• 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.
