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 sup-
plies engine shutdown and extinguisher discharge timing
and activation. The dry chemical and/or foam system dis-
charges 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 maxi-
mize effectiveness of the suppressant and to prevent re-
ignition 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: die-
sel, gasoline, hydraulic fluid, and other fuels, including
hydrogen.
