BUS

A SUPERIOR SUPPRESSION TECHNOLOGY LIMITS THE CONSEQUENCES

Fogmaker takes safety seriously. Fogmaker fire suppression system with high pressure water mist is a superior suppression technology in an engine or enclosed compartment, limiting the consequences of a bus fire.

HOW IT WORKS

OUTSTANDING CHOKING AND COOLING TECHNOLOGY

High-pressure water mist has an outstanding choking and cooling effect. The system is always active – no power supply is needed for activation or system monitoring. Fogmaker chokes the fire quickly, yet has a longer emptying time than many competing systems – which is critical to prevent reignition and downtime. This also buys valuable time for evacuation.

ADVANTAGES

A SMALL BUT IMPORTANT INVESTMENT

The investment in an efficient high-pressure water mist system will only be a miniscule part of the total investment when procuring new buses. In case of a fire, the effectiveness of the system limits the damage and helps keep repair costs down.

Throughout the world, organizations have found automated fire suppression systems in the engine room an important fire safety measure. Furthermore, some insurance companies and bus operators require fire suppression systems, and the demand is rising, in part due to new legislation according to UN ECE R107.

About 50 European countries have signed this legislation, and countries outside Europe seem to follow. In practice, R107 means that every new bus that exceeds 22 passengers must have an OEM homologated fire suppression system in the vehicle.

THE SYSTEM

FROM FIRST APPROVED SYSTEM TO MARKET LEADER

FIRST FIRE SUPPRESSION SYSTEM APPROVED IN ACCORDANCE WITH R107

Fogmaker is approved in accordance with the latest international standard for fire suppression systems in buses. Fogmaker became the first manufacturer to implement the official tests with successful results in October 2016. Fogmaker also made the first fire suppression system available with the type approval – UNECE Regulation No.107 Cert. No. 06001 (2017-01-18).

Fire testing procedure follows four tests from SP method 4912.

SPECIFICS FOR AN R107-APPROVED FOGMAKER SYSTEM*

*Depending on the risk assessment for each specific engine, upscaling of extinguishant volume and number of nozzles will occur. The data below is the minimum requirement for the stated engine compartment gross volume.

Gross volume “engine compartment”: 4 m³
Extinguishant volume: 6.1 litres
Number of spray nozzles: 11 pcs
Type of nozzle: “Hollow cone nozzle” 1.2 l/min– Distance most remote nozzle: 8 m

Fogmaker was the first fire suppression system approved according to R107. Today, Fogmaker is the leading suppression system in buses on the European market.

MORE INFORMATION ABOUT UNECE REGULATION 107

Legislation towards improved fire safety in buses and coaches in Europe (47 contracting parties applying).

Fixed installed FSS (Fire suppression system) will be a part of the bus manufacturer´s vehicle approval.

The requirement of installation of FSS applies to the vehicle.

FSS systems can be approved as a “component” by test in a defined test rig or installed in a specific engine compartment.

R107 covers the following vehicles exceeding 22 passengers:

Class I (standing passengers)
Class II (seated and standing passengers, like city buses)
Class III (seated passengers, like coaches)
