KVS-2025 Automatic 
Fire Sensing System
FEATURES
• Vehicle Fire System Control Panel
• Expandable, modular
• Programmable Time Delay
• Multiple system discharge capability
• Battery Backup Module
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.
