Versatile Fire Protection for Critical Small-to-Midsize Enclosures

The BlazeCut T Series R with FK-5-1-12 is a compact, fully self-contained fire suppression system designed to protect small to mid-sized enclosed or semi-enclosed spaces where fire risk is high and downtime isn’t an option. The system activates automatically—no wiring or power required—when temperatures inside the enclosure reach critical levels.

This upgraded model includes an integrated pressure switch, allowing for seamless system integration. When the unit activates, the two-pole switch can trigger an alarm panel, flashing beacon, or automatically cut power to the protected equipment—adding intelligent, active response to BlazeCut’s already passive, self-contained system.

The detection tube itself is abrasion-resistant and filled with a powerful Clean Fire Suppressing Agent (FK-5-1-12). Upon reaching approximately 267°F (±6°F), the tube melts at the hottest point, forming a nozzle that releases the clean agent directly onto the source of the fire. The result is fast, targeted suppression—without mess, residue, or downtime.

Ideal For:

  • Marine Applications – Inboard/outboard engines, jet skis

  • Road Vehicles – Cars, SUVs, vans, classic cars, off-road builds

  • Mobile Machinery – Compact forklifts, utility vehicles, power trolleys

  • Battery Enclosures – Mid-sized solar banks, hybrid systems, EV conversion kits

  • Medium Electrical Panels – Distribution boxes, motor controls, UPS enclosures

  • Small Generator Compartments – RVs, trailers, telecom, and power backup systems

Key Benefits:

  • Automatic Activation – No need for wiring or external triggers

  • Integrated Pressure Switch – Use to trigger alarms, beacon lights, or automatically shut down power during activation

  • Clean Fire Suppressing Agent (FK-5-1-12) – Safe for electronics, people, and the planet

  • Environmentally Responsible – Zero ozone depletion, low global warming impact

  • Compact & Self-Contained – Installs directly inside the space it protects

  • Integrated Pressure Gauge – Easily confirm system status at a glance

  • Simple DIY Installation – Includes zip ties; horizontal mounting recommended

  • No Maintenance Required – Long service life, up to 10 years

What Makes FK-5-1-12 Different?

FK-5-1-12 is a non-toxic, non-conductive, and residue-free clean agent that’s safe for people, equipment, and enclosed spaces. It’s also one of the most environmentally friendly fire suppressants available, with zero ozone depletion potential and a very low global warming potential—making it a smarter, safer alternative to traditional halon-based agents.

Frequently asked questions

How does BlazeCut work?

BlazeCut uses a heat-sensitive tube containing extinguishing agent. When exposed to high temperatures, the tube melts and releases the agent to suppress the fire automatically.

Where can BlazeCut be installed?

Common installation sites include engine compartments, electrical cabinets, data centers, and enclosed spaces at risk of fire; it’s important to check specific product volume recommendations for each enclosure.

What types of fires does BlazeCut suppress?

BlazeCut is effective on electrical, liquid, and solid fuel fires, particularly in small closed spaces.

What is the lifespan/shelf life of a BlazeCut system?

The tube and system can last between 5 and 10 years, depending on environment and application.

Does BlazeCut leave behind residue or damage equipment?

BlazeCut uses clean agents which do not conduct electricity, corrode, or damage electronics, and are safe for people in typical application volumes.
