Over 275,000 vehicles across over 20 countries worldwide are fitted with Collins Aerospace AFES systems. Drawing on our more than 40 years of fire suppression experience, AFES safeguards crews and vehicles automatically and at reaction times that cannot be matched by manual systems.

Our AFES system features Dual Spectrum® sensors that quickly and accurately detect fires and explosions in areas like crew spaces and mechanical compartments. It uses high-speed valves to release approved extinguishing agents within 120-150 milliseconds, effectively suppressing fires or explosions caused by vehicle penetrations. The system discriminates between actual fire events and false alarms, only activating when a genuine explosion or fire occurs. Collins Aerospace ensures comprehensive vehicle integration with strategically placed optical sensors, fire extinguishers, and control panels, validated by Agent Concentration Tests and supported by extensive expertise from initial design through live fire testing.

Typical vehicle integration

Optical sensors are located throughout the protected zone so that the entire space is monitored. Fire extinguishers are in supportive locations with distribution nozzles to ensure sufficient agent concentrations reach all parts of the protected space. An Agent Concentration Test (ACT) is typically conducted to validate concentration design. The control electronics panel is located within easy reach of driver and/or commander. Our engineers are experts in vehicle integration with experience on many vehicles from conceptual design to government live fire testing.
