Wireless battery doorbell, TECHNO, range 100 meters, TYPE: ST-251, black SUN10000385

Wireless Doorbell – Comfort and Functionality at Your Fingertips

This TECHNO ST-251 battery-powered wireless doorbell is a practical solution for both homeowners and installers. The set consists of a doorbell and a button, which provide reliable communication at a distance of up to 100 meters in open areas. Installation is extremely simple – it does not require running cables or interfering with the electrical installation, which significantly reduces installation time and costs.

Flexibility and Customization

The doorbell offers a wide range of personalization options. The user has as many as 36 melodies and sounds to choose from, as well as 3-level volume control, allowing them to adjust the signal level to individual preferences and environmental conditions. Additionally, optical ringing indication is particularly useful for people with hearing impairments. The sound mute function will also be useful in homes with small children or in situations requiring silence.

Construction and Durability

The doorbell button is equipped with a housing with an IP44 protection rating, which guarantees its resistance to weather conditions – rain, snow or sunlight do not pose a problem for it. The doorbell and button are powered by batteries (2x AA for the doorbell, 1x CR2032 for the button), which ensures independence from the electrical network and easy power replacement. The ability to program up to 4 buttons to one doorbell increases the functionality of the system, allowing it to be expanded in the future. The device operates at a frequency of 433MHz. There are three operating modes available: sound, optical, and a combination of light and sound – this allows for full adaptation of the doorbell to individual user needs.
