Fire protection for military vehicles

• ExAct Titan is a pioneering fire protection system solution that extends the use of a bus-based operations model to mobile military applications.
• The system uses advanced, military-specific CAN (Controller Area Network) technology.
• 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.
