Electromechanical two-tone doorbell Bim-Bam, GNT-921 8V, beige SUN10000146

Electromechanical two-tone gong – reliable notification

This electromechanical gong is a simple and effective solution for signaling in homes, offices or workshops. It is ideal as a doorbell, internal call device or personal alarm. Made of durable plastic, it ensures long-lasting and trouble-free operation. The characteristic "BIM-BAM" sound is well audible and easily recognizable.

The GNT-921 gong is designed for electrical installations with a voltage of 8V AC. It is worth noting its versatility – it will work both in newly built installations and when replacing existing doorbells. Because it is wired, it does not require battery replacement, which translates to convenience and no additional costs.

Installation and use

Installation is simple and intuitive, and the step-by-step instructions allow even people without experience in electrical work to connect it correctly. It is important to disconnect the power in the doorbell installation before starting work to ensure safety. In addition, some models (e.g. GNT-921/N) have a built-in switch that allows you to temporarily mute the doorbell – useful, for example, during a baby's nap or focused work. The sound level is approximately 78 dB, which provides clear sound signaling in most rooms.

Construction and parameters

The housing made of plastic protects the internal elements from mechanical damage and external factors. The IP20 protection class means that the device is intended for use in dry indoor environments. The gong operates at a temperature of 0°C to +35°C, which ensures its reliability throughout the year. The weight of the device is approximately 0.25 kg and its dimensions of 106 x 136 x 42 mm make it easy to mount in various places.
