Public transport vehicles are relied upon by many people across the UK and the world. Fires in buses and coaches can have serious implications that go beyond damage to the vehicle. If the fire is not detected and controlled rapidly, it can put passengers and the driver at risk. Bus and coach fires also have a high profile, affecting the reputation of the bus operator.

Fires on buses and coaches can go unnoticed until the fire is already out of control. Quickly bringing the vehicle to a stop and evacuating passengers can be difficult. An increase in zero-emission buses and coaches on the roads has raised awareness of the need for fire protection on these vehicles too, with electric vehicle fires in particular causing significant damage and potential injury if the fire is not contained before passengers and driver are evacuated.

Under UNECE Regulation 107, all new buses and coaches must be fitted with an automatic fire suppression system. This regulation aims to increase safety for passengers, drivers and other road users, as bus fires starting in the engine compartment can quickly become uncontrollable.

How Our Fire Suppression Systems Works

Fire Detection

The Ardent Fire Suppression System for buses and coaches uses either a Linear Heat Detection (LHD) cable or pneumatic detection tubing depending on the application and customer requirements. The system can be configured to pre-warn the driver when high temperatures are detected, allowing the driver to pull over safely before the fire ignites.

System Activation

Once a fire is detected, the system will initiate the discharge of the suppression agent within a matter of seconds. There are a range of optional extras that can be fitted to provide voice messages to the driver to alert that a fire has been detected or to provide system status updates to reassure the driver that the system is fully operational.

Agent Distribution

Ardent offers direct and indirect fire suppression for flexible solutions for vehicles of all sizes. The UNECE R107 Fire Suppression System stipulates indirect distribution be installed.

In the direct system, the detection tubing doubles as the distribution network. The suppression agent is discharged directly from the point of rupture, which is the closest point to the fire. This allows for rapid fire suppression, minimising damage and disruption.

The indirect system targets all identified fire hazards in the vehicle to ensure reliable fire suppression. When the system detects a fire, the suppression agent is released through the distribution network of carefully placed nozzles to flood the protected area.

Fire Suppression Agents

The Ardent Bus & Coach Fire Suppression Systems use dry chemical suppression agent, also known as dry powder, which is highly effective on most types of fire, including Class A, Class B, Class C and electrical fires. This makes the system flexible for use with internal combustion engines and electric, hydrogen and hybrid vehicles. The dry chemical powder is proven to offer rapid fire knock-down and suppression, with excellent coverage.
