Fire Protection System for Buses
Fitech Vehicle’s fire suppression systems are thoroughly tested for performance and environmental durabilities such as vibration, corrosion and extreme temperatures according to international vehicle standards to ensure the highest performance. The condensed Aerosol Fire Suppression system protects critical zones to ensure both passengers and equipment remain protected. The systems can be installed directly inside the engine compartment close to the high-risk area.
- Detecting fire in the Engine
Bus fire suppression systems work by detecting and suppressing the fire before it spreads. The Linear Heat Detector cable is a double conductor steel braided cable with a special heat-sensitive insulated sheath wrapped with a protective tape and overall surrounded with a high-performance fluoropolymer sheath.
When the temperature rises above 138°C the insulation of the conductor fuses inside the engine compartment. Because of the twisted condition of the steel wires, there is the mechanical force required to trigger immediate short circuit conditions. The Linear Heat Detection Cable melts and consequently shortens the circuit. This triggers the alarm panel at the driver’s cabin.
- Discharging the Agent
The signal from the panel activates the aerosol canisters which are non pressurised metal containers equipped with a device to trigger the discharge of the compound immediately and it spreads the potassium salt aerosol inside the engine compartment.
- Suppressing the Fire
Salient Features of the System
The system does not require pipes and nozzles which are exposed to mechanical fatigue from vibrations thus making it very easy to install.
The Aerosol canisters are Compact and lightweight having a rugged design and do not require maintenance. They are made of steel and are automatically activated.
The Aerosol produced is non toxic to passengers, environmentally friendly and does not damage mechanical equipment.
It is designed to protect the engine compartments and does not cause damage to the vehicle
The infinitesimal size of the particles does not generate dirt in the engine compartment in the event of discharge even if the engine is running.
Protection against Class A (surface), B, and C fires.
The System meets the specification of AIS135 Fire Detection and Alarm System (FDAS) & Fire Detection and Suppression System (FDSS) for Buses and can be tailor made to meet the customer’s requirements.
