Most bus fires start in engine compartments and surrounding areas. A tested and classified fire suppression system in combination with good fire detection, is the best first response in case of an emergency.

Dafo Forrex Fire Suppression System gets activated by heat detectors when the temperature reaches 180oC.

The Dafo system is developed to use worldwide in both cold and hot climate and designed after the new UNECE Regulation No UNECE R107 and the Swedish guideline SBF 128, which requires 3L extinguishing agent for 1m3 protected space.

It means, we leave nothing to chance, safety first! The Dafo system is designed to avoid false releases – one of many special qualities.

The liquid agent extinguishes fire in less than a second and effectively prevents re-ignition. A low pressure system demanding but modest space and that operates down to -50oC.

As the owner of a vehicle equipped with a Dafo Forrex Fire Suppression System, you have taken an important step in facing the fire problem. This flexible, fully automatic system detects and suppress fire in less than a second.

It’s totally independent of orientation while maintaining a 100% discharge of the agent. Emptying time approx. 20 sec.

Actuation is achieved through a linear heat detector wire which detects the fire in a really early stage. Means to manually release the system can be provided upon request. The agent is released through a pipe system with specially designed nozzles that effectively covers the protected areas and easily adjusts the amount of extinguishing agent.

Forrex Installation

Fire is indicated by a linear heat detector wire, that sends a signal to the actuator, which punctures the propellant gas cartridge and releases nitrogen to the agent container. That distributes the Forrex liquid to the nozzles through the pipe system. At the same time the alarm system is activated, an alarm horn in the bus and a light signal in the panel will warn the driver.

Personnel Security

The harmless extinguishing liquid and no pressure resting state represents no health risk to passengers or mechanics.

Benefits of Forrex:

  • Strong Cooling Effect
  • Film forming effect to prevent re-ignition
  • Pressure-less container (Personnel safety)
