DESCRIPTION
The Kidde® KVS detection system uses a fast response, infrared fire sensor, spot heat detection and/or Linear Heat Sensing Cable, all of which continually monitor the hazard area for a fire condition. Once a fire is detected, a signal is immediately sent to the control panel located in the operator’s area where a “FIRE” lamp is illuminated and an audible alarm is sounded. The control unit supplies engine shutdown and extinguisher discharge timing and activation. The dry chemical and/or foam system discharges suppressant routed through distribution hoses to nozzles located in the engine compartment, hydraulic network and other identified potential fire areas. The vehicle engine can be automatically shutdown to maximize effectiveness of the suppressant and to prevent reignition of the fire.
The Kidde KVS Automatic Fire Sensing and Suppression Systen is designed to detect and automatically suppress vehicle fires. The system responds to fires fueled by: diesel, gasoline, hydraulic fluid, and other fuels, including hydrogen.
Areas where fires can occur include:
•Engine Compartment:
–Fuel Tanks and Lines
–Hydraulic Reservoirs
–Lines and Accumulators
•Heaters
•Transmissions
•Battery Compartment
•Electrical Distribution and Raceways
