Fire on a vessel is different. There is no hydrant. No engine company around the corner. No second chance.

Whether it’s a galley flare-up, an engine room ignition, an electrical compartment short, or a lithium battery incident, seconds determine whether you save the vessel — or abandon it.

That’s why SuppressAll® Aerosol Fire Suppression Systems were engineered specifically for enclosed, high-risk marine environments. From commercial fleets to municipal patrol boats, these systems are built for the realities of life at sea.

Why Marine Operators Are Moving Toward Aerosol

Traditional marine fire suppression methods often rely on water or pressurized cylinders — both of which come with serious limitations onboard a vessel. Aerosol technology offers a smarter alternative for enclosed spaces.

SuppressAll systems require no onboard water supply and use a non-pressurized design, eliminating the risks associated with stored cylinders. They do not displace oxygen and leave no corrosive foam residue behind. Because they are waterless, they prevent secondary damage to electrical systems, generators, and sensitive onboard equipment.

The systems are lightweight and compact for tight compartments, offer up to a 15-year shelf life, and are proudly made in the USA. When you’re operating offshore or away from immediate support, simplicity and reliability matter.

Ideal Marine Applications

SuppressAll systems are designed for enclosed, high-risk compartments commonly found on vessels and waterfront facilities. These include engine rooms, bilge compartments, generator rooms, electrical panels, battery banks and lithium storage lockers, and galleys.

They are also well suited for harbor patrol vessels, tugboats, workboats, commercial fishing fleets, municipal marine units, marina service buildings, and fuel docks.

Anywhere fire can ignite in a confined space, aerosol suppression delivers rapid knockdown without the collateral damage of water or foam.

Portable Protection:FS2-MAX(Manual Deployment)

When seconds count, pull the pin and deploy.

The FS2-MAX is built for rapid, manual response in tight marine compartments. Once activated, it floods the enclosed space with aerosol suppressant, reducing temperatures by up to 1,000°F in under 60 seconds.

Its non-pressurized design carries a Class A, B, and C fire rating and provides coverage for spaces up to 5,300 cubic feet. With a 10-year battery life and 15-year shelf life, it’s a dependable onboard solution.

The FS2-MAX is ideal for engine flare-ups, galley fires, electrical panel ignitions, and machinery space incidents. For crews who need immediate response capability without relying on external systems, it delivers fast, contained suppression.

Wall-Mount Manual or Automatic: FS4400

For compartments requiring built-in protection, the FS4400 combines detection and suppression in one compact unit.

It automatically activates at 185°F, provides a pre-warning at 149°F, and uses self-powered thermodynamic activation — meaning no external energy source is required. The unit is maintenance-free and features an IP67-rated detection module for durability in marine conditions.

The FS4400 is ideal for engine compartments, generator rooms, mechanical enclosures, storage lockers, and shore-side marina facilities. It is also available with a magnetic marine-grade bracket for secure mounting, even in rough sea conditions.

Fully Automatic Detection + Communication: FS8100

Detection. Alarm. Suppression. Communication.

The FS8100 integrates full detection, alert, and suppression capabilities into a single system. It detects fire, sounds a 95dB siren, activates a strobe, deploys aerosol suppression, and sends SMS, cellular, and email alerts — all while operating independently of external power and without subscription fees.

This system is designed for enclosed marine machinery spaces, harbor authority vessels, dockside fuel facilities, marina electrical rooms, and battery or lithium storage compartments. Your fire protection system should never rely solely on shore power. The FS8100 ensures protection even when the grid isn’t available.

Why Waterless Suppression Matters at Sea

Water may extinguish flames — but onboard a vessel, it often creates a second disaster.

Excess water can damage electrical systems, disable generators, accelerate corrosion, flood bilges, and create costly cleanup and extended downtime. In marine operations, downtime equals revenue loss.

SuppressAll aerosol suppression leaves no water damage behind. It does not deplete oxygen and is non-toxic, non-corrosive, and non-conductive. By minimizing equipment loss and reducing cleanup time, it protects both your vessel and your operational continuity.

Made for Marine Professionals

SuppressAll systems are already deployed in municipal and harbor authority applications, including marine units operating in New York Harbor.

When fire breaks out at sea, you don’t get a second attempt. You need immediate knockdown. You need enclosed-space suppression. You need a system that works without relying on the grid.

That’s SuppressAll.
