We’re proud to share that our vandal-resistant telephone model JR308-FK has been successfully installed in newly constructed tunnel projects across Hong Kong and Singapore.

Designed for tough environments, the JR308-FK provides reliable communication in high-risk, high-noise areas such as tunnels, metros, and industrial zones. With a robust metal body, weatherproof sealing, and anti-vandal features, it ensures operational safety and instant response when it matters most.

Project Highlights:
✅ Deployed in active construction tunnels
✅ Integrated with existing emergency systems
✅ Customized mounting and wiring based on site needs
✅ Delivered on time with full technical support

Special thanks to our local partners and on-site teams for their great efforts in completing these installations smoothly.

J&R Technology remains committed to supporting global infrastructure with reliable, durable, and smart industrial communication solutions.
