FireDETEC Fire Suppression System for Buses First to Gain SP Approval

FireDETEC is the first fire suppression system to be awarded this important certification.

The SP Technical Research Institute of Sweden has developed a new certification system designed to create a safer environment for bus passengers and drivers worldwide. The SPCR 183 is a test methodology specifically written to test the effectiveness of fire suppression systems in bus engines, according to the SP Method 4912, chapter 3. It is a more robust test methodology than previous test protocols, as it evaluates fire suppression performance under more realistic bus engine conditions, and it includes specific measures of durability under harsh conditions as well as an audited quality assurance program of the manufacturer.This new standard is now being reviewed by a United Nations general safety working group as a possible global standard for buses. If adopted, this would mean that the installation of approved fire suppression systems in engine compartments will be mandatory for all single-deck, double-deck, rigid or articulated vehicles of category M2 or M3.

Andrè Proes, Sales Manager from Rotarex Firetec, commented: “Bus operators should have more confidence with a fire suppression system carrying the P-mark because it certifies effectiveness under the realistically harsh conditions that bus engines operate. Soon every bus will likely require an on-board fire suppression system based on the SP Method 4912 because it helps save passenger lives.Our FireDETEC systems are an effective and economical way to reduce risk to passengers and assets, as well as to be compliant with pending future legislation.”

FireDETEC’s patented technology is installed directly in the engine compartment, closer to where most bus fires start. It uses pneumatic detection tubing that is highly effective, economical and easy to install. Plus, it withstands the harsh conditions of a moving vehicle engine. A special liquid agent suppresses oil-based fires in high airflow conditions and uses a sustained discharge to prevent fire re-ignition. It also warns drivers via a special dashboard alarm, so they have time to stop the bus and evacuate passengers. In most cases, the fire will be out even before the driver has time to stop the bus.

Mr. Proes went on to explain how FireDETEC works: “If a fire occurs, the heat causes the pressurized sensor tubing to burst at the point closest to the fire. Sudden de-pressurization actuates a valve and instantly floods the entire compartment with a liquid-based agent that suppresses the fire moments after it began.”

About FireDETEC
FireDETEC compact fire suppression systems designed specifically for critical equipment and machinery at high risk for fire. It protects the spaces left under-protected by traditional fire fighting systems. Flexible fire sensor tubing using pneumatic technology is installed between the critical circuitry and mechanics, closer to where fire starts. Quickly detecting a young fire and triggering immediate release of an extinguishing agent, FireDETEC systems suppress a fire before it can do significant damage. FireDETEC technology is operating in over 60,000 installations worldwide.
