TECHNICAL DATA CONSTRUCTION
Most bus fires start in engine compart-ments 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 get activated by heat detector when the temperature reach 18O°C.
The Dafo system is developed to use worldwide in both cold and hot climate and designed after the Swedish guideline SBF 128, which requires 3L extinguishing agent for 1m3 protected space. It means, we leave nothing to chances, safety first! The Dafo system is designed to avoid false releases-one of many special qualities.
INSTALLATION
Fire is indicated by a linear heat detector wire (1) that sends signal to the actuator (2) which punctures the propellant gas cartridge (3) and releases nitrogen to the agent container(4) that distributes the Forrex liquid to the nozzles(5) through the pipe system. At the same time the alarm system system is artivated, an alarm horn(6) in the bus and a light signal in the panel will warn the driver(7).
OPERATING INSTRUCTIONS IN CASE OF FIRE
Have a hand portable extinguisher ready for safety when opening the engine compartment hood. The alarm to the fire system will sound until the detection wire is cut of, by cutting the wire next to the control unit or by removing the fuses. Do not start the bus until the cause of fire is determained, and service have been done.
