Guardian Technical Specifications PDF 

The Guardian III  Model (G300-B) is a unique, state-of-the-art residential, range-top automatic fire suppression system for your home. It is also approved by Underwriter's Laboratories (UL & ULC) for the protection of residential cooking equipment in light commercial occupancies*, such as group homes, dormitories, day care centers, church kitchens, fire stations, break rooms, libraries, and civic group meeting halls. This self-contained system can be installed by a handy homeowner or contractor in under an hour.

When a stove-top fire occurs the sensor will activate at a pre-set temperature and signal the main CPU board.  This board automatically sends a signal to release the extinguisher valve assembly, discharging the wet agent and simultaneously activating the CPU mounted alarm.
More outputs are available for additional accessories to be utilized upon the system's activation.  Each system can also be wired into an existing alarm panel showing system activation.  This system is UL and ULC listed with a fuel shutoff and is listed with or without a pull station.

• No Electrician Needed for making wiring shut-off connections during the installation, thus saving money.

• This system normally can be installed in about an hour!

• This system activates automatically at a pre-set temperature, thus not using a mechanical fusible link, during the detection mode.

• This system is the most user friendly and easiest for the average home-owner to install.
