Fire suppression system

Learning from past experience.

The fire suppression system in the crew’s quarter detects and extinguishes fire and or deflagration during the initial phase. And this is of enormously important. Experience from recent wars has told us that almost all vehicles were destroyed due to fire in the crew’s quarter.

It’s a matter of saving lives.

The installation of such system not increases the vehicle’s ability to survive – it also increases the crew’s chances of survival. This is more than sufficient reason to recommend these systems as essential components of the safety concept for military vehicles.


There always will be exposure to risk.

In spite of reduced fire burden in the vehicles interior (e.g. electric turret drive), almost any hit causes fire.

Increasingly exposed to such risks are armoured vehicles and crew transporters. Particularly insidious and dangerous are attacks with Molotov cocktails against armoured personal carriers with open flaps and hatches.


Safety onboard.

Similar to fighting systems, fire suppression systems are fixed installed fire suppression systems in combat vehicles. Their task is to identify fires and deflagrations during their initial phase directly in the crew compartment, and to extinguish them speedily.


System Safety.

Before integrating the fire suppression system, the installation is inspected in each combat vehicle. The free volume of the crew compartment determines the quantity of required extinguishing agent. Advantage: As the extinguishing agent already is effective at a low concentration, the demand is relatively low. The number and position of detectors are determined during a sample installation. Both detectors and containers are installed in such a way that the fire is detected instantaneously and can be extinguished in approx. 150 milliseconds – irrespective of where it originates.  


Protection in milliseconds.

The fire suppression system extinguishes an explosion-like fire within max. 150 milliseconds. This is fast enough to protect the crew against its lethal effects (high temperatures, high pressure, loss of oxygen, toxic gases).


The fire suppression system consists of three main groups:
A. Fire detection system
B. Extinguishing system
C. Control device

In addition, there is an integrated system: The so-called stand-alone system.
