Over 275,000 vehicles, among over 20 countries worldwide, are fitted with Kidde 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.
The AFES system comprises extremely fast and highly accurate Dual Spectrum® sensors which detect fires and explosions in zones such as crew areas and mechanical compartments. Additional protection systems are available supporting external and wheel and track areas. The AFES extinguishers are equipped with high-speed valves to immediately flood affected compartments with efficient and approved extinguishing agents. Typical reaction times from detection to full suppression are 120 - 150 milliseconds. Fire or explosions caused by rounds penetrating the vehicle are effectively suppressed by this near-instantaneous response and remain within the limits of published survivability criteria for personnel. The system provides discrimination capability which prevents false alarms from a Kinetic Energy (KE), or High Explosive Anti-Tank (HEAT), round penetration that does not result in an explosion or fire. The suppression system is triggered only when an explosion or fire event occurs.
Typical Vehicle Integration
Optical sensors are located throughout the protected zone, so that the entire space is monitored. Fire extinguishers are located in supportive locations with distribution nozzles located to ensure sufficient agent concentrations reach all parts of the protected space. An Agent Concentration Test (ACT) can be conducted to validate concentration design. The control electronics panel is located within easy reach of driver and/or commander. Kidde’s engineers are experts in vehicle integration with experience on many vehicles from conceptual design to government live fire testing.
