Wireless doorbell with kinetic button – convenience and reliability

This Rumba ST-370 wireless doorbell is a practical solution for both home and business. The set consists of a battery-powered doorbell and an innovative button that requires no batteries – the energy needed to operate it is generated when pressed. This is savings and ecology in one!

Design and application

The Rumba ST-370 doorbell has been designed with durability and weather resistance in mind. The waterproof button will work even in harsh weather conditions, and its operation is guaranteed even after complete immersion in water. This is an ideal solution for entrances exposed to rain or snow. The doorbell can be used as a traditional doorbell, an internal call device or even a personal alarm. The ability to program up to 3 buttons to one doorbell increases the functionality of the system, especially in larger buildings.

Advantages and benefits

• Battery-free button: Eliminates the need to replace batteries in the button, which translates to savings and convenience. Kinetic technology allows energy to be generated during pressing.
• Waterproof button: Ensures reliable operation in all weather conditions, even after accidental flooding.
• Large range: The operating range of up to 100 meters in open areas guarantees that the signal will reach even from the more remote corners of the property. However, it should be remembered that obstacles may reduce it (wood/plaster by 5-20%, brick by 20-40%, reinforced concrete by 40-80%).
• Wide selection of melodies: As many as 32 sounds and melodies are available to the user, allowing for doorbell personalization.
• Volume control: The ability to adjust the volume (up to 80 dB) allows you to adjust the sound to individual preferences and environmental conditions.
• Optical signaling: Optical ringing signaling is particularly useful for the hard of hearing or in noisy environments.
• Expandability: The ability to program up to three buttons to one doorbell makes it easier to expand the system in the future.
• Radio frequency: Operates at a frequency of 433 MHz providing stable communication between the button and the doorbell.

Thanks to the combination of modern technology and solid construction, the Rumba ST-370 doorbell is an investment for years to come, providing comfort and safety of use.
