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.
