ExAct Titan – Military vehicle fire suppression systems

Re-thinking fire protection

ExAct Titan fire protection

ExAct Titan is an innovative fire suppression system for armoured military vehicles and containers. The system protects the crew and the vehicle against all kinds of fires. Explosive fires and armour penetrations are detected and suppressed in milliseconds and slow-growth fires in a couple of seconds. The system prevents pressure build-up, temperature rise and formation of toxic gases.

  • CAN bus technology ensures fast and reliable communication between system components.
  • The system is always up to date and capable of immediate response.
  • System components are connected in loop form. Even if the cable loop is hit by a fragment, the system will continue to operate.
  • The CAN bus design allows for easy changes or extensions of the system.
  • The system is modular, consisting of standardized, addressable components.
  • The same components can be used in different applications.
  • There are very few component types compared with conventional fire protection systems.
  • The components are configured through the control unit.
  • All system components are interconnected via a local bus.
  • ExAct Titan integrates with vehicle control systems (vehicle management systems, C4I etc.)
  • The system responds to changes in vehicle operation and adapts its operation accordingly.
  • The system operates differently e.g. when the vehicle is in motion or when the vehicle is parked and unoccupied.
  • ExAct Titan transmits information to vehicle systems.

The ExAct Titan fire protection system detects and suppresses all fires, whether slowly growing or instantaneous, small or large:

  • Detects and extinguishes slow-growth fires in a couple of seconds.
  • Detects and suppresses explosive fires and armour penetrations in milliseconds.
  • ExAct Titan provides excellent protection against modern fire threats, such as IEDs.
  • Improved fire safety makes it possible for the crew to stay in the vehicle if a fire occurs.
  • Reliable system operation is based on several factors, including:
    • fast and secure local bus communication
    • intelligent component design, and
    • advanced built-in self-testing and self-diagnostics.
  • High false alarm immunity – ExAct Titan employs several methods to eliminate the possibility of false alarms:
    • situational awareness and adaptability
    • coincidence detection (flame detectors operating in coincidence mode)
  • Low maintenance requirement
  • Fast and efficient operation: ultra-fast detection and suppression of fires and explosions
  • Reliable operation, high false alarm immunity
  • Safe operation ̶ protecting the people, property and the environment
  • Excellent technical performance characteristics, see “Performance” for more details.
  • The level of protection is tailored to the application requirements.
  • The system provides an inexpensive way to increase the safety of the crew and the vehicle.
  • Components feature superior MTBF and MTTR figures (mean time between failures, mean time to repair)
  • Advanced self-testing and self-diagnostics minimize the need for periodic maintenance.
  • Low configuration management costs due to small number of components
  • Short service downtime: quick replacement of plug-and-play components
  • Long system service life
    Commonality of components and procedures across systems and applications
  • The ExAct Titan system can be customized for a variety of applications.
  • The system protects 1 to 4 separate compartments in one vehicle.
  • In addition to one control unit, each system may contain up to 32 other components.
  • System components can be combined in numerous ways to create the desired configuration.
  • System configuration can be modified as requirements change. The system can be upgraded, expanded, reduced, and even transferred to another vehicle.
  • The same component types can be used to protect new vehicles, upgrades and modernizations.
  • Fully automated system operation. The system automatically adapts its operation to changing conditions.
  • Minimal user intervention required: the driver and the crew need not pay any attention to the system under normal circumstances.
  • When attention is required, the system will alert the operator with an audible signal and a message on the user interface unit.
  • The user interface unit responds to user activity and presents context-sensitive options.
  • Critical information will be displayed and communicated to the vehicle control system.
  • The system is safe and easy to use and requires minimal servicing.
