## Long description

The ORNO Quatro Two-Tone Gong is a wired doorbell designed for permanent installation on a 230V AC mains supply.

The product is intended for fixed mounting with standard mains wiring and provides a simple, reliable audible alert for entrances where a distinct chime is required.
Advantages
The Quatro Two-Tone Gong offers a compact design that fits standard interior spaces and a two-tone sound pattern that improves recognition of the doorbell signal. Operated from a 230V AC supply, the unit eliminates the need for batteries and supports continuous, low-maintenance use. The mechanical/electromechanical gong mechanism delivers consistent acoustic performance and straightforward installation using common wiring practices.
Suitable for
Private homes and apartments requiring a mains-powered doorbell
Small offices, clinics and retail premises with light commercial use

Key specifications
Power supply: 230V AC mains
Sound type: two-tone mechanical/electromechanical gong
Housing colour: black
Mounting: fixed, wall or surface installation with standard wiring

How to use
Connect the unit to a 230V AC mains circuit following local electrical regulations and standard wiring conventions. Mount the gong in a suitable indoor location where the sound can propagate through the premises, using screws or mounting points provided. After wiring and mounting, test the chime by activating the associated doorbell push button; the unit should produce the two-tone gong sound.

Usage recommendations
For reliable performance, install the gong in a dry, indoor location away from direct moisture and extreme temperatures.
