Tunnel Emergency Telephone System Function Demonstration

High-Reliability Tunnel Emergency Telephone Solution

In enclosed traffic environments such as highway tunnels and

urban tunnels, the tunnel emergency telephone system is a

crucial communication facility for ensuring personnel safety

and improving emergency response efficiency. In the event

of vehicle breakdowns, traffic accidents, or fires, the tunnel

emergency telephone provides on-site personnel with a

one-touch emergency communication channel directly to

the control room.

I. Tunnel Emergency Telephone System Components

This tunnel emergency telephone system adopts a

centralized management and distributed deployment

architecture, suitable for tunnels with separate left and

right bores.

System Equipment Composition

Aluminum Explosion-Proof Tunnel Emergency Telephone

Main Unit

Installed on the tunnel wall, conspicuous and easy to identify,

facilitating quick use in emergency situations.

Control Room Terminal

Deployed in the monitoring center, enabling unified management

and dispatch of tunnel emergency telephones.

Left Bore / Right Bore Tunnel Emergency Telephone Extension

Units

Covering the entire length of the tunnel, supporting independent

communication and inter-bore communication.

This tunnel emergency telephone system uses a stable wired

network connection to ensure clear and reliable voice

communication.

II. Core Functions of the Tunnel Emergency Telephone System

1. Control Room Calling Emergency Telephones in the Tunnel

Press the call button

Automatically connects to the tunnel emergency telephone

within 5 seconds

Supports clear and stable two-way voice communication

No manual answering required, suitable for emergency situations

2. Intercommunication between Left and Right Tunnel

Emergency Telephones

Left and right tunnel emergency telephones support direct dialing

Supports 0000 quick dialing

Enables instant communication across different areas within the

tunnel, improving collaboration efficiency

3. Multi-channel Tunnel Emergency Communication

The control room can simultaneously call emergency telephones

in both the left and right tunnels

Suitable for accident command, emergency dispatch, and unified

broadcast announcements

Effectively shortens emergency response time

III. Tunnel Emergency Telephone System Operation Demonstration

IV. Technical Advantages of the Tunnel Emergency Telephone

System

1. Fast Response Mechanism

All tunnel emergency telephone calls

Are automatically answered within 5 seconds

Avoiding time loss caused by manual operation

2. Explosion-proof Aluminum Material, Safe and Reliable

The tunnel emergency telephone uses explosion-proof 

aluminum die-casting technology

Possesses impact resistance, corrosion resistance, moisture

resistance, and dust resistance

Suitable for high humidity, high dust, and strong vibration

environments in tunnels

3. Industrial-grade Stable Operation

The tunnel emergency telephone system supports 7×24

hours of continuous operation

Long-term stable operation, low maintenance costs

Meets the high standards of the transportation industry for

safe communication equipment

V. Application Value of the Tunnel Emergency Telephone

System

As an important part of tunnel safety facilities, the tunnel

emergency telephone system can effectively achieve the

following in practical applications:

Rapid reporting of tunnel emergencies

Real-time voice command between the control room and

on-site personnel

Efficient dispatch of emergency rescue forces

Reducing secondary accident risks and improving the

overall safety level of the tunnel

Against the backdrop of continuous advancement in

intelligent transportation and tunnel informatization

construction, the tunnel emergency telephone system

has become an indispensable basic communication

equipment for highways and urban tunnels.
