Fire detection & Suppression system (FDSS)

The few common reasons for fire accidents of Buses & Coaches amongst them 

• Extreme heat
• Vehicle vibration
• Material Malfunction 
• Fuel / Hydraulic fluids leakage 
• Electric short circuits
• Improper / inadequate maintenance

In many bus fire accidents fire originates in either the engine or battery compartment, which are usually out of drivers sight / Passenger sight.
It is therefore difficult for the driver to notice a fire if it occurs. which might result in a slow response time increasing both life loss & damage risk.
To overcome this FDSS system is used to improve safety of passengers & vehicle.

FDSS system consists of 

Command & control unit

Control Pannel

Linear heat detector 

Dry chemical cylinders

Discharge hoses

Discharge nozzle

Blow of cap

Control Pannel Surface mounted or flush mounted via external mounting feet.Internally pre wired for connection to other system electrical components via plug connectors.

Dry Chimical Agent Cylinders

FDSS in Engine compartment

FDSS in Battery compartment

Discharge hoses&nozzle

Working of FDSS

• Tubing linear fire detector is routed in Engine/Battery compartment.
• In case of fire or high temperature fire detector is activated which drive a "Pre Alarm" & "Fire Alarm" directly to the control panel mounted on dash board of the vehicle.
•  Alerting a driver by visual indicator & by activating the audio buzzer.
• Even before driver can see the fire allowing both automatic & manual system activation .

In India AIS 135 standard is set for FDSS
