UN Regulation No. 107, Revision 6 Amendment 5, Annex 13 - Part 1 prescribes automatic fire detection and suppression systems are a requirement for certain buses and coaches. Fire protection is no longer optional or supplementary but now a mandated component for certain passenger buses and coaches.

The Jactone 6KG ABC Dry Powder PAFSS (automatic fire detection and suppression) system has been rigorously third party tested and certified to meet the requirements of the UNECE 107 regulation.

Equipro Ltd is the global exclusive Jactone PAFSS supplier to the bus and coach market. We can support you meet the mandatory requirement to install a tested and approved automatic fire detection and suppression system for the engine bay. 

Please note that we are seeking more sales and installation channel partners worldwide to help us support the bus & coach industry meet this United Nations mandated safety regulation. Please contact us if this is something that fits your business for an initial discussion.

Bus & Coach manufacturers: Equipro can support you make your vehicles ready to install PAFSS systems in the field to meet the needs of UNECE 107 or can help you factory fit complete PAFSS systems so your vehicles are UNECE 107 compliant at point of supply.

How do Equipro's Jactone PAFSS Systems Protect Buses from Fire?

Jactone PAFSS UNECE 107 approved Fire Detection & Extinguishing Systems are activated by heat impinging on AEGIS advanced & proprietary Fire Detection Tubing. The AEGIS pneumatic linear heat sensor complies to DIN standards DIN73378 / DIN74324  meaning it is the only fire detection tubing available globally that is specifically rated for use on vehicles and engine spaces. AEGIS detection tube is exclusively manufactured for EQUIPRO by a specialist polymer handling company.

The AEGIS detection tube is installed in the bus engine bay. At commissioning the detection tube is pressurized with nitrogen. The AEGIS detection tube is connected to the JACTONE PAFSS UNECE 107 approved 6KG Dry Chemical System, holding the system valve closed. When a fire starts in an engine bay the temperature rises. This rise in heat is detected by the AEGIS detection tube. The AEGIS detection tube is weakened by the heat rise and the pressure of the Nitrogen in the tube overwhelms the tube to rupture and escape. The fall in pressure inside the tube causes the Jactone PAFSS system to activate. The dry chemical extinguishing agent is then discharged via 3 or 4 discharge nozzles mounted in the engine bay according to the requirements laid down in the UNECE 107 approved system manual. A fire is normally detected and extinguished in a few seconds. The UNECE Approval tested the Jactone PAFSS system performance and was found to be excellent at detecting, extinguishing fires and also preventing re-ignition.
