It started with one rescue volunteer
BTC began with a rescue volunteer in Maha Sarakham who built his own siren because imported units cost too much and cheap ones failed in the rain. Today we assemble and test every unit for Asian roads, and still answer every customer ourselves.
NOT GOOD, NOT FOR SALE
If it isn't good, we don't sell it. Every unit is sound-checked on every button before packing, and carries a warranty with clear terms.
The name
BTC stands for Beacon Tech Compounds, a home for warning-light technology. SONE is our zone of light.
