Two Tone Gong

The AD-2T one and two tone gong is extremely compact – but it is big on specifications and quality, and introduces several innovative features.

SKU ad-t2 Categories ,


The AD-2T one and two-tone gong is a compact yet high-quality device that boasts several innovative features. 

One such feature is the ability to remotely control the volume of the AD-2T allowing for a 50% reduction during user-specified periods. This enables the lift arrival at each landing to be sounded at full volume during peak hours, while reducing the volume during off-peak hours. Additionally, the volume of individual AD-2T gongs can be independently adjusted to achieve optimal levels for each landing.

Despite its compact size and weight of only 44 grams, the AD-2T produces a sound pressure level of up to 86 dB with excellent tone and clarity, outperforming gongs that are three times as heavy and twice the size.
