How It Works

Guardian Fire Shield™ combines a 5 lb. dry-chem ABC fire extinguisher-style cylinder with a heat-activated trigger that will only discharge its non-toxic dry powder at 135 degrees F. – in the presence of a real fire, not smoke.

It can be placed virtually anywhere added protection is needed, without expensive plumbing or other installation costs. It has been tested to provide effective fire suppression in a least a 16 ft. x 16 ft. area.

Installation is Easy

Guardian Fire Shield is designed to be installed in minutes to provide you with years of protection. Designed to be mounted above a conventional drywall ceiling, it can also be mounted between open joists, or directly to a solid concrete ceiling or wall with the use of our optional mounting hangers.

Install it Yourself

Installation is quick and easy: cut a 5.25” hole with an ordinary keyhole saw, insert the cylinder, and secure the cover. Complete installation guide available here.

16’ x 16’ Coverage

The Guardian Fire Shield™ was independently tested to provide effective fire suppression in at least a 16’ x 16’ area.

135 degrees Heat activated

The heat-activated trigger means the Guardian Fire Shield™ will not discharge in the presence of smoke. It must be extremely hot (ie. a real fire) in order for the unit to automatically discharge.

No water damage

Unlike water suppression systems, the dry-chem agent in the Guardian Fire Shield™ does no damage when discharged.


The non-toxic, dry-chem agent used in the Guardian Fire Shield™ is safe when discharged and easy to clean up as it is essentially a form of baking soda.

Easy clean up

The super-fine ABC dry-chem agent inside the Guardian Fire Shield™ cleans up easily with a vacuum in the event of a discharge.

10-year protection

The Guardian Fire Shield™ can protect your loved ones and your valuables for 10 years (not including battery replacement for pressure testing sensor and indicator).

One year warranty

The Guardian Fire Shield™ comes with a 1-year limited warranty and a $5 million certificate of liability.

-45°C operation

Since cold temperatures won’t affect performance, the Guardian Fire Shield™ is perfect for use in outbuildings of all kinds (sheds, barns, garages etc), and it requires no power.
