A fire suppression system (10) for a vehicle having an engine (11) and a fire extinguisher (36) located proximate thereto. Previous systems of this type have not given any positive indication to the vehicle operator of the presence of an engine fire and have allowed the operator to remain in the cab

A fire suppression system (10) for a vehicle having an engine (11) and a fire extinguisher (36) located proximate thereto. Previous systems of this type have not given any positive indication to the vehicle operator of the presence of an engine fire and have allowed the operator to remain in the cab (23) of the vehicle. In the present invention, operation of the fire extinguisher (36) automatically causes actuating means (25 or 32) and flow-interrupting means (14 or 19) to cut off fuel flow to the engine (11) and automatically causes the vehicle horn (34) to sound a warning of variable intensity. The horn warning can only be terminated by opening a disconnect switch (22) located outside of the vehicle cab (23), so that the vehicle operator is required to leave the cab (23) to restore the horn (34) to normal operation.
