Abstract
A portable fire extinguisher includes a tank defining a volume containing a fire extinguishing material and further defining a tank outlet, and a valve assembly mounted at the tank outlet. The valve assembly includes a valve housing, a valve disposed relative to the tank outlet for metering release of fire extinguishing material from the volume, a valve trigger mounted for movement of the valve between a first position for containing fire extinguishing material within the volume and a second position for metering release of fire extinguishing material, and a gauge disposed in communication with the volume for display of pressure condition of fire extinguishing material within the volume. The portable fire extinguisher further includes an electronic circuit (31,32'"'"') mounted thereupon to issue a signal, e.g., an audio or visual signal upon detection of a predetermined condition, e.g., an internal condition, such as low or high tank pressure, low battery power, or lack of inspection reset, and/or or external condition, such as smoke, or lack of light or external power.
