SECRUI M520+F55 Wireless Doorbell Kit – 3 Receivers, 2 Buttons, 58 Chimes, 1000ft Range

Overview

The SECRUI M520+F55 wireless doorbell kit arrives ready to use, with no wiring or electrician needed. Simply plug the receiver into a wall outlet and you’re set. The sleek black design blends with modern interiors while delivering crisp, clear chimes across your space, whether bustling with activity or quiet after hours.

Designed for reliable delivery, the FM-based wireless link minimizes cross-signal interference and uses one-to-one pairing to ensure alerts reach the intended receiver. In open environments, expect robust performance across rooms, hallways, or small yards. While the official spec lists up to 1000 ft in typical settings, experienced setups can extend further in obstacle-free conditions (up to roughly 1300 ft).

Customization and convenience

Customize your doorbell experience with 58 chime options and five volume levels. The system supports multiple configurations, such as one button with one receiver, or one button with two or three receivers, allowing you to cover multiple entry points without cables.

• 58 selectable chimes to fit mood or circumstance
• Five adjustable volume levels for different days and environments
• Flexible pairing to mix and match receivers with buttons as needed

Durability and efficiency

Housed in sturdy ABS material, the doorbell is built for daily use. It features IP55 dust-proof and waterproof protection and operates in temperatures from -4 °F to 140 °F. The transmitter is energy-conscious, consuming power only when pressed, which helps extend battery life to 1–3 years depending on use.
