What Is a Tunnel Emergency Telephone?

A tunnel emergency telephone is a robust communication device designed specifically for use inside tunnels, ensuring immediate contact during emergencies. Built with waterproof, dustproof, and corrosion-resistant materials, it delivers reliable performance in dark, humid, and high-noise tunnel environments.

Applications of Tunnel Emergency Telephone

Tunnel emergency telephones are widely used in road tunnels, subway systems, rail tunnels, and utility tunnels. Installed at regular intervals along tunnel walls, they enable drivers, workers, or passengers to instantly report accidents, fires, or equipment failures. These phones are often connected to control centers and support hands-free or push-to-talk communication. Their high visibility and durability make them essential for tunnel safety systems.
