Marine & Offshore

There may be significant differences in size and usage but all marine vessels, boats and offshore oil rigs have one thing in common, an absolute commitment to avoiding a fire on board.

There may be significant differences in size and usage but all marine vessels, boats and offshore oil rigs have one thing in common, an absolute commitment to avoiding a fire on board. The obvious implications of a fire at sea, coupled with highly flammable materials and compact spaces mean even small fires can be dangerous. The proximity of the galley and the engine compartment to passengers and crew requires dedicated marine fire suppression systems that can automatically suppress offshore fires in an instant. 

Fire Protection Technologies offer a wide range of fire detection and suppression systems that are specifically designed and approved to prevent catastrophic fire aboard marine vessels. These systems range from wet chemical and water mist systems to protect the galley to various gaseous and water mist systems to protect engine spaces, as well as specific systems to protect control rooms, communications centres and the like.  These fire suppression systems are complemented by a wide range of state of the art fire detection systems to ensure rapid detection and suppression of fires. 

MA2 Series Gaseous Suppression:

Ideal for boats with engine rooms up to 42.5 cubic metres in size, this series has an automatic discharge feature with an optional manual discharge, when used with a Fireboy Manual Discharge Cable, which is sold separately. Vertical or horizontal mounting is allowed. 


  • Automatic discharge with optional manual discharge when used with a Fireboy Manual discharge cable  
  • Engine rooms up to 42.5 cubic metres 
  • Vertical or horizontal mounting allowed 
  • Utilises HFC-227ea (FM-200) 

GA2 Series Gaseous Suppression:

The Fireboy GA Series is a patented, pre-engineered total-flooding fire extinguishing system designed to protect larger boats with engine rooms from 42.5 cubic metres to 85 cubic meters. Each system requires twin extinguisher cylinders; flexible braided stainless-steel hosing, two overhead temperature sensors, fire-resistant manual release cables, and an engine shutdown. 

Four temperature sensors monitor the engine room temperature 24 hours per day. Two of the temperature sensors are located on the manifold blocks of the cylinders. The remaining two temperature sensors are installed above the engines and are linked to the extinguisher cylinders with ¼” stainless steel flexible hosing. When the engine room temperature reaches 79C at any of the four temperature sensors, the system with completely discharge the clean agent HFC 227ea (heptafluoropopane or FM-200) in less than 10 seconds to successfully extinguish the fire. No powder or residue is left behind. The GA Series is approved by the U.S.C.G. up to 56.5 cubic metres on inspected vessels and up to 85 cubic metres on recreational craft. Factory Mutual, RINA, Bureau Veritas and CE certified.


  • Two-cylinder system for larger vessels with engine rooms from 42.5 cubic metres to 85 cubic meters  
  • Cylinders are linked with flexible braided stainless-steel hosing allowing for a simultaneous discharge of both cylinders. 
  • Requires the installation of Manual Discharge Cables 
  • Vertical mounting only 
  • Utilises HFC-227ea (FM-200) 

Fireboy Gas Detection Range:

Fireboy-Xintex, an ISO 9001-2008 company, offers a comprehensive line of gas detection products and accessories. Designed in-house by our team of engineers, these products cover a wide range of marine, transportation and commercial applications. Fireboy-Xintex provides application-specific sensors and monitors that will safely detect carbon monoxide, gasoline, or propane fumes before they reach the hazardous stage. 

Carbon Monoxide Detectors:

Carbon Monoxide (CO) is produced wherever fossil fuel combustion occurs, inducing the operation of gasoline engines and heating and cooking appliances. It is invisible, odourless, tasteless and deadly. Faulty venting or even a wind shift can create a dangerous situation, [particularly in confined areas like boat cabins and sleeping quarters. 

CO enters the bloodstream through the lungs, blocking the oxygen your body needs. Prolonged exposure to low concentrations or short exposure to high concentrations can be fatal. Typical symptoms of Co exposure can be mistaken for the flu, seasickness, or intoxication, making accurate on board CO detection a necessity. 

Gasoline Fume Detectors: 

Gasoline fumes in a bilge or engine compartment, with or without a blower fan, have the potential to be a serious risk at any time. Firstly, because fuel leaks create new fumes as rapidly as the blower clears old fumes away. With the fan off, the hazard is increased. 

Secondly, the blower fan is typically not operating prior to engine start-up, thus offering no protection from the ignition of fumes be electrical short circuit, battery hydrogen explosion, smoking or their causes. 

Fireboy-Xintex offers a full line of gas detectors and accessories to match your specific needs. 

Marine Propane Detectors:

Propane has become the fuel of choice for cooking and heating. Highly BTU-efficient and readily available, propane is becoming more and more a part of power boating, sailing and camping. 
Propane is heavier than air and can settle below deck and in the bilge where it can be detonated by an engine start-up or electrical spark of any kind. Fireboy-Xintex® Propane Fume Detectors will alarm when fumes reach 18-20% LEL (Lower Explosive Limit) 

The Fireboy-Xintex® line of propane products includes everything you need for outfitting a complete and safe propane system. 

Engine Shutdown Systems

Compressed gas suppressants such as HFC-227ea will not stall a diesel engine. If a fire breaks out aboard a diesel powered vessel, the engine(s) must be shut down immediately for the Fireboy fire extinguisher system to effectively extinguish the fire. Continued engine operation may remove the agent, lowering the concentration required to effectively extinguish the fire, making an Engine Shutdown System necessary.

Pneumatic Liquid Level Monitoring System

Measuring marine water and holding tanks requires a reliable system. The new generation of Fireboy-Xintex pneumatic liquid level monitoring senders and display gauges were designed with no moving parts to stick or clog, giving you peace of mind knowing that you are getting the most accurate readings possible.
