Is installation easy?

Absolutely, installation couldn’t be simpler!
A 5 ¼” hole is cut in the ceiling (between ceiling joists) with a regular handheld keyhole saw or suitable power saw, and the Guardian Fire Shield™ slides easily into this hole.

Does the unit activate when I burn toast?

No. The unit is unaffected by smoke. It is activated by a heat-sensitive fusible link. When the temperature at the unit reaches 135° F/57° C the Guardian Fire Shield™ will activate. At this temperature, there is a fire in your house.

Will the Guardian Fire Shield™ extinguish fires?

It can. However, every fire is unique because every home is unique and the contents of each home are different. Because of these variables, the Guardian Fire Shield™ is considered an automatic fire suppression system. In any case, the Guardian Fire Shield™ gives you more time to evacuate.

What Is an automatic fire suppression system?

Automatic fire suppression systems control or extinguish fires without human intervention. Examples include fire sprinkler systems, gaseous fire suppression and condensed aerosol fire suppression.

How many Guardian Fire Shield™ units do I need in my house?

It depends on the layout of your house and the amount of protection you want. Tests have proven the Guardian Fire Shield™ to suppress or extinguish fire in a 16′ x 16′ room, so a unit every 8-20′ would be optimal. At the very least, consider placing them so as to protect the access and egress from your bedroom at night. You can also install more units in areas of higher fire risk such as kitchens, or where the Christmas tree usually is.

Will just one Guardian Fire Shield™ unit protect my egress at all, or do I need several?

We recommend one in every bedroom (maximum 8 feet from the door) and in your hallways leading to the exit (every 8 feet).

Is the ABC dry chem inside the Guardian Fire Shield™ dangerous to my health?

No. The ABC dry chem inside the Guardian Fire Shield™ is non-toxic. Similar to what’s used inside a typical fire extinguisher, except Guardian Fire Shield contains 90% suppressant and 10% filler, whereas most fire extinguishers are 60% suppressant and 40% filler. We use the finest dry extinguishing agent available. It is a slight eye and lung irritant that also has a terrible taste.

Is It safe for pets?

Absolutely. The ABC dry-chem inside the Guardian Fire Shield™ is non-toxic, similar to what’s
Used in a typical fire extinguisher. The powder can be a slight irritant, but for pets (and people) the Guardian Fire Shield gives you more time to escape the toxic fumes of a fire.

Is the Guardian Fire Shield™ better than a water sprinkler system?

We believe that both systems have their advantages. However, water sprinklers are very expensive to install in a new house, and even more expensive as a retrofit in an existing house. We believe that the Guardian Fire Shield™ is a more cost-effective alternative that the average home owner can afford.

How long does the Guardian Fire Shield™ last?

The Guardian Fire Shield™ comes with a 1-year manufacturer’s warranty against defects, and provides protection for 5 years. When you purchase a Guardian Fire Shield™ we strongly recommend that you register your Guardian Fire Shield™ unit(s) with us. When your Guardian Fire Shield™ expires, we will notify you and you can exchange your expired unit for a new one at a discounted price.

Does the Guardian Fire Shield™ need batteries?

Yes, just one for the LED pressure indicator, although this is not needed for operation. This is simply to indicate that the tank is pressurized when you press the button. It is not essential for effective operation. The battery inside the Guardian Fire Shield™ is a standard 9V battery which can last several years.

Does the tank have to be inspected every year, just like a fire extinguisher?

No. The Guardian Fire Shield™ is equipped with an LED light. When the pressure inside drops, the LED light on the Guardian Fire Shield™ will flash, indicating you have no protection

How long is the warranty?

Your Guardian Fire Shield™ is warrantied for one full year against manufacturer defects. We recommend you register your Guardian Fire Shield™ with us for warranty/exchange purposes.

What will my insurance company think of the Guardian Fire Shield™ unit in my home?

To date, we have support from insurance companies. Our product will save lives and decrease home fire and water damage.

House insurance discounts may be provided by your insurance broker, please discuss this with them and show them this website.

How is it affected by cold? If I put a Guardian Fire Shield™ in the cottage and we shut down the cottage in the winter, will that affect it?

The cold does not affect the unit at all, although cold may shorten the life of the 9V battery and thus keep the pressure indicator light from working. Even without the battery, the unit would still be fully charged and functional. It will not lose pressure in extreme cold.

If you place this in the kitchen as the first place (where a Christmas tree is situated may be another place), how close to the fire hazard (stove, tree) does it need to be for it to work properly?

The unit should be placed about 4 feet from the fire hazard for the best protection (and to discharge on an angle under your range hood).

Is it rechargeable (is there an expiration time frame ) and does it need recharging or can it be recharged?

Yes, we can recharge the units at our factory after they discharge or after the 5-year life expectancy, for a fraction of the price of purchasing a new unit.

What is the minimum joist height required for installation?

Given the existing faceplate size and assuming a 5 ¼” hole in the ceiling, the joist should be 8” high. If the joist is 6” deep the Guardian Fire Shield™ can still be installed, however a larger hole will need to be cut and the extra space covered by a custom covering. Our faceplate won’t completely hide a larger hole.

What is the ideal ceiling height?

The Guardian Fire Shield™ operates optimally when installed in 8-12′ high ceilings. If the ceiling is higher than 12′ the unit will not provide the same coverage, so units would need to be placed closer together in those circumstances.

Has the Guardian Fire Shield™ been tested?

Yes, many times, and it performed flawlessly. The Guardian Fire Shield™ has been tested in independent fire scenarios, successfully suppressing a fire in a 16’ x 16′ room.

Won’t this put a hole in my vapour barrier on the upper floors?

Yes, it is similar to a pot light installation with minimal disruption to the vapour barrier. However, it is very easy to place a small amount of plastic over the unit to continue the vapour barrier, which any contractor can easily do.

Can it then be installed in a wall instead of a ceiling?

We recommend ceiling installation as that has the optimal dispersion of the suppressant over a large space, and is the only installation we have tested extensively. We also offer other mounting options where ceiling mounting is impractical.

In the ceiling, what supports the weight of the tank, since its weight is offset?

The unit comes with a foam pad attached with double-sided tape. This pad rests against the base of the unit when it is installed in a ceiling, to support the weight of the tank.

What are the exact dimensions of the Guardian Fire Shield™ unit?

Unit weight: 7.4 lbs., 8.4 lbs. packaged dimensions: 8 1/16” wide x 9 ½” deep x 17 ½” tall.

Unit dimensions: 4 ⅜” diameter tank, 15 ⅝” tall, 7 ½” deep at faceplate.

In the case of a fire, and it dispenses, how toxic is it for people to breathe in?

Although the ABC dry-chem inside the Guardian Fire Shield™ is non-toxic, it is a mild eye irritant and tastes terrible. It is basically like breathing in a yellowy, gross-tasting, baking powder.

In the event that the Guradian Fire Shield™ “goes off”, what is the clean up like?

Clean up is done with a vacuum. Unlike water, there is no damage from the non-toxic dry-chem agent used in the Guradian Fire Shield™.

Is there a UL or ULC listing for this product?

The Guardian Fire Shield™ has been tested at the UL labs in Chicago, successfully suppressed the fire in a 16’x16′ room, and uses UL-certified materials and components in its manufacturing.

While most of the components in the Guardian Fire Shield™ are UL listed,  we have been told by UL that there is no standard for our product to be tested to, since it is “too new and innovative.” There is no standard by which to measure the Guardian Fire Shield™ against other products in its category because it is the only product in its category.

UL, like CSA (Canadian Standards Association) issues blanket “approvals” based on known performance measurements and standards. UL has stated that the Guardian Fire Shield™ is not a sprinkler, therefore, it cannot be measured against water sprinklers. Nor does the Guardian Fire Shield™ deploy in the same manual manner as traditional fire extinguishers, therefore, it cannot be measured against fire extinguishers. It may take years for UL to develop standards, using the Guardian Fire Shield™ as a base measurement, to have standards for all others to meet.

We have been instructed that since there is no standard, this product is able to be marketed as an optional add-on for home safety (similar to a home security system).
