SECRUI Wireless Doorbell M520+F55 – 2 Receivers, 58 Chimes, 1000ft Range, Easy Install

SECRUI M520+F55 Wireless Doorbell

Designed for modern homes, offices, and classrooms, the SECRUI M520+F55 system blends convenience with solid performance. Two push buttons trigger two chime receivers, creating flexible alerts across spaces. In open space, the range can reach up to 1000 ft, helping you stay connected even when you’re moving between rooms or buildings.

With 58 distinct chimes and five adjustable volume levels from 0 dB to 110 dB, you can fine-tune notifications to suit the moment—quiet for late evenings, louder during gatherings, or a gentle tone for everyday entryways. An LED flash adds a visual cue that’s useful for hearing-impaired users or when ambient noise is high. A handy memory feature preserves your chosen melody and volume after power cycling, so you don’t have to reset settings each time you reconnect power.

What makes it stand out

• Two push buttons and two receivers enable simultaneous alerts in multiple zones.
• Long-range capability: up to 1000 ft in open space, adaptable to larger layouts.
• 58 chimes and 5 volume levels offer versatile notification options for different occasions.
• LED flash provides a quick visual cue in dim environments.
• Memory of the last melody and volume saves time after power interruptions.
• Wired-free setup with simple plug-in power and wall mounting using tape or screws.
• Each transmitter can pair with up to 20 receivers for scalable coverage.

Real-world use cases

In a large home, position transmitters at the front and back doors, with receivers in the living room and study for reliable alerts as you move through the space. In an office or school, the system can help signal visitors or deliveries across multiple rooms without creating noise in nearby areas. For nurseries or elder-care settings, it can function as a discreet pager-style alert, keeping caregivers informed while you focus on activities. The visual LED cue complements the audio for a more inclusive experience.

Because you can assign different chimes to different doors, you can quickly identify where a visitor is arriving. The modular design also means you can extend coverage by adding more SECRUI receivers or push buttons if your space changes, without sacrificing ease of use or reliability.

Setup and expandability

No wiring is required—just plug the adapter into a wall outlet and mount the transmitter with tape or screws. Pair each transmitter with up to 20 receivers, and add more components to tailor coverage to your layout. The system also pairs well with other SECRUI devices, allowing you to create a cohesive alert network across locations.
