It started with one rescue volunteer

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 SALENot good, not for sale.

Read our story

Wire it yourself, 5 wires

The 18S W295-R uses five wires. Connect them by colour and it's ready.

12 V only. Connecting 24 V or reversing polarity will damage the unit and void the warranty.
