Phono Grigia

Flush-mounting bell, non-removable, 1 module size, with two different types of sound: two-tone and three-tone. 

What is a electronic bell and what is it used for 
Electronic bells are a type of ringtone that use two distinct sounds, emitted simultaneously or in rapid succession, to create a distinctive signal. 
They are usually used in homes or rooms/shops to simulate the siren effect, suitable for example as an alarm in bathrooms, or simply to reproduce the sound of the doorbell even in several separate areas of the home/room. 

Installation tips and adaptability
You can adapt the device to the cover frames of the main switch and socket systems, thanks to adapters included in the package.

Design
Phono Grigia has a minimal design (only one module), which allows it to be discreetly installed anywhere in the house blending seamlessly with the environment. 

Vemer also provides Phono Argento and Phono Bianca.
