How It Works

Automatic Fire Detection Combined with Effective Fire Suppression

Although it resembles a smoke detector, Guardian Fireshield actually uses a heat-sensitive fusible link for activation. When the temperature at the unit reaches 135° F/57° C, the link melts and releases non-toxic fire suppressing powder from a 5 lb. dri-chem ABC fire extinguisher-style cylinder. Because it is activated by heat and not smoke, it is not subject to false alarms like a smoke detector: at the activation temperature, there is a real fire. It does not need wiring or plumbing, and the only battery it uses powers a warning light for the low pressure indicator to show the cylinder needs recharged. Even with a dead battery, the unit will still work properly as long as the cylinder is charged. The units can also be wired into home security and fire alarm systems.

Product History

2013 – July

Two Canadian inventors and volunteer firefighters had an idea: create an automatic fire suppression system to reduce the damage and injuries from kitchen fires. It would use a ceiling-mounted heat-activated fire extinguishing unit to discharge the fire-suppressing chemical powder once heat from a fire filled the room.

2013 – October

The inventors worked with Canadian aerospace manufacturer E.T.M Industries to turn their home-built version into a working prototype.

2015

The first workable production model was released.

2015

The product, then known as Haven Fire Suppression, succeeded in attracting investment on The Dragon’s Den television program.

2016

E.T.M. added a producing/assembling line for the device to their facility.

2017

The product was rebranded as Guardian Fire Shield to highlight its ability to protect property and the people you love.

2018

The World Bank became our first major international customer. Guardian Fire Shield had gone global.
