Electromechanical two-tone gong – reliable notification

The GNS-921 gong is a solid and easy-to-install signaling device, ideal for both home and commercial use. The two-tone "BIM-BAM" sound with a volume of approximately 85 dB provides a clear and audible notification of a visit or event. The housing made of black matte plastic blends perfectly with modern electrical accessories.

Installation and application – for professionals and users

The device is intended for installation in 230V AC doorbell systems. Installation is simple, but due to the mains voltage, it is recommended to entrust it to a qualified electrician. The gong will work as a doorbell, an internal call device, or an element of an alarm system. Remember to protect the power circuit with an appropriate fuse or overcurrent switch.

Installation tips:

• Before starting work, disconnect the power supply and make sure the installation is safe.
• Use copper wire with a cross-section from 0.5 mm² to 2.5 mm² with double insulation.
• Pay attention to the vertical position of the gong during wall mounting – it is marked on the housing.
• Securely fasten the wires in the connection terminals.
