Automatic fire extinguishers are essentially the same as ordinary extinguishers - with one important difference. The squeeze grip handles are replaced with a glass bulb, filled with a heat-sensitive liquid. As the temperature rises, the liquid expands, and when temperatures rise above 79 degrees centigrade, the bulb breaks, activating the extinguisher. A specially adapted spray head then covers the surrounding area in the fire fighting agent, either powder, or FE36 gas (for expensive or sensitive electrical equipment).

Superb in confined areas such as engine rooms or boats, a Firemaster automatic fire extinguisher can have detected, deployed and extinguished a fire probably before the premises or boat owner even knows one has broken out! They are also suitable for agricultural machinery, mining equipment and telecoms installations
