5. AUTOMATIC FIRE SUPPRESSION
SYSTEM (AFSS)
The vehicle is equipped with an Automatic Fire
Detection and Suppression System (AFSS)
intended to automatically detects and suppress
an engine compartment fire. The system also
includes real-time driver status warnings and
alarms as well as an automatic engine shutdown
function.
The system operation is fully automatic but can
be manually activated by the operator at any
time.
Refer to Prevost Operator’s Manual for system
operation and operational sequence (fire).
If more information is needed regarding the
system, please refer to Kidde 182246A

5.1 STARTING THE VEHICLE AFTER A
FIRE ALARM
The vehicle may be started after a fire alarm
without resetting the system. This will not reset
the system, rather it will instruct the vehicle’s
multiplex system to ignore vehicle interface
outputs. This feature is intended to be used only
in emergencies that require the vehicle to be
restarted and moved a short distance prior to
system reset. It should not be performed if the
cause of the fire has not been clearly identified
and corrected.
NOTE
For information, refer to Kidde 182246A
document – “OM Manual-Prevost 45ft Diesel
Buses at NYCT"
