Is it the right fit?
Who the M520 in colour suits
A good fit when
Teachers use a doorbell to call a class to order, and a bright one is hard to lose on a crowded desk. This is the M520 in rose red or green: same chime, same button, same 58 melodies.
It is paired before it ships. Plug in the chime, press the button, and pick a melody and one of five volume levels. The button is IP55 and reaches 1,000 feet in open air.
Know before you buy
- Colour is the only change from the black and white M520.
- Sold as one button and one receiver only.
- The chime needs a wall outlet.

What buyers say about the M520 in colour
5 out of 5
Perfect for my classroom. I teach elementary music and we can get very loud so I don't always hear when someone knocks at my door. This little doorbell is loud and has several pleasant tones to choose from. Easy to set up, too! Very cute, and eye catching so my students spotted it right away.

I got. Both pink and green. They work great for my kids. Instead of calling them downstairs, I just push the doorbell.
Brandy Dale, September 9, 2026 5 out of 5
Very easy to install. Love the green color. Easy to see in the hallways. Yhe volumn sounds great. The size is great for small spaces.
