Guardian - Model G300B - (for Gas Stoves) - Automatic Residential Fire Suppression System w/Gas Shut-off
The Guardian III Model (G300-B) is your home's unique, state-of-the-art residential, range-top automatic fire suppression system. 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, daycare centers, church kitchens, fire stations, break rooms, libraries, and civic group meeting halls. A handy homeowner or contractor can install this self-contained system 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.
No electrician is needed to make 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 homeowner to install.
