Haven Automatic Heat-Activated Fire Extinguisher, Non-Toxic, ABC, 5 Year Worry-Free Industrial and Urban Protection -Great for Home, Kitchen, Office, Apartment, High Rise Buildings. Get Peace of Mind &#9989;BUYS YOU VALUABLE TIME  Independently tested to provide effective fire suppression in at least a 16'x16' area. Since cold temperatures don't affect performance, the HAVEN is perfect for use in attics, sheds, garages, Cottages, and outbuildings of all kinds (no power is required either). Left alone, the HAVEN can protect your loved ones and your valuables for 5 years (not including battery replacement for testing purposes). &#9989;NO FALSE BEEPS/ALARMS  Since the HAVEN is heat-activated, not smoke-activated, it won't trigger in low-risk instances of accidental smoke. Only when a real fire is present will the HAVEN discharge the MSDS safe, non-toxic, dry chem into the room. &#9989;EASY INSTALLATION AND CONVENIENT  Installation couldn't be simpler. A 5 3/4. hole can be cut with a regular handheld keyhole saw, and the HAVEN slides easily into this hole between floor Joists. Operating independently, the HAVEN can be placed as a fire extinguisher kitchen or virtually anywhere added protection is needed, without expensive plumbing or installation costs. &#9989;NO FUSS & EASY CLEANUP  Unlike water suppression, the dry-chem agent in the HAVEN does not cause extensive damage when discharged. The super-fine ABC dry-chem agent inside the HAVEN cleans up easily with a vacuum in the event of a discharge. &#9989;TRUSTED PRODUCT  Designed by a Firefighter and manufactured in Canada with certified components. The non-toxic dry-chem agent used in the HAVEN is safe when discharged, as it is essentially a form of baking soda used in many households.
