Wireless Door Bell with 150 Metre Range and 433MHz Signal

This wireless door bell is built around a simple need: hearing when someone is at the door without relying on a fixed wired connection between the push button and the bell. The source text states a remote control distance of 150 metres, a 433MHz wireless frequency, and a bell power range of 110-250V. Volume adjustment is available across 4 levels, which helps in rooms where a fixed loudness may be too much or too little. The product is listed with several style options, including one button with one bell, one button with two bells, two buttons with one bell, and one button with three bells. Model options include CH, Heart, and UK. Type 0 is also stated. Together, these details describe a wireless door bell system intended for practical door alert use across a range of distances and power settings.

Features and Construction

The main technical details in the source text cover wireless range, frequency, bell power, and volume control. These are the facts that define how the product can be positioned and installed. The style options also affect what the setup looks like in practice, because the number of buttons and bells changes with the chosen configuration.

Wireless Range and Frequency

The stated remote control distance is 150 metres, which is the maximum distance given for the wireless connection between the button and the bell. The wireless frequency is 433MHz. These two details are the core of the product's wireless operation. No further signal performance claims, such as penetration through specific wall types, are provided in the source text. The 150-metre figure should therefore be treated as the stated remote control distance, not as a guaranteed result in every building layout.

Power and Volume Control

The bell power is listed as 110-250V, which is the stated electrical range for the bell unit. This is relevant when checking whether the product suits the available power supply. Volume adjustment covers 4 levels, giving a choice of loudness settings. This is useful where the bell needs to be heard in one part of a building but not overpower another. No decibel rating is provided, so the 4 levels should be understood as the available adjustment steps rather than a measured sound output.

Uses and Placement

The product is suited to door alert use where a wireless connection is preferred. Because the source text gives a 150-metre remote control distance, it can be considered for larger homes, separate rooms, offices, workshops, or outbuildings within that stated range. The available style combinations also allow for simple or expanded setups.

Single and Multi-Bell Setups

The style options include one button with one bell, one button with two bells, two buttons with one bell, and one button with three bells. A one-button one-bell setup is the most straightforward arrangement. A one-button two-bell or one-button three-bell setup can place alerts in more than one room. A two-button one-bell setup can cover two entrance points with a single bell. These are the configurations stated in the source text, and no additional combinations are confirmed.

Everyday Door Alert Use

For everyday use, the bell can be positioned where it is most likely to be heard, while the push button remains at the door. The 4 volume levels allow adjustment to suit the room. The 110-250V bell power range should be checked before installation. The 433MHz frequency is the stated wireless band for the signal. No smart-home features, app control, or additional connectivity options are listed, so the product should be treated as a straightforward wireless door bell.

Benefits and Buying Value

The practical value of this wireless door bell comes from the stated distance, the adjustable volume, and the choice of style configurations. It avoids the need to rely solely on a wired door bell connection within the limits of its stated wireless range. The model options also provide a choice between CH, Heart, and UK versions where available.

Adjustable Volume and Range

The 150-metre remote control distance and the 4 volume levels are the two most useful day-to-day details. The distance supports placement flexibility within the stated limit, and the volume adjustment helps match the alert to the environment. The 433MHz frequency is stated for the wireless link. These features are practical rather than decorative, and they are all taken directly from the source text.

Choosing the Right Style

Choosing between one button with one bell, one button with two bells, two buttons with one bell, and one button with three bells depends on the number of entrances and the number of listening points required. Model options CH, Heart, and UK may also affect the appearance or regional suitability where supplied. Before buying, check the bell power range of 110-250V and the 150-metre stated remote control distance against the intended installation. No price, warranty, or battery information is provided in the source text.
