Remote fire extinguisher station inspection
First Claim
1. Apparatus for remote inspection of portable fire extinguishers in installed positions at one or a system of fire extinguisher stations, said apparatus comprising:
- a fire extinguisher gauge mounted to a portable fire extinguisher comprising a fire extinguisher tank defining a volume containing fire extinguishing material stored under a predetermined range of pressure, said gauge being disposed in communication with the volume for detection and display of pressure condition of the fire extinguishing material contained within the volume of the fire extinguisher tank; and
an electronic circuit in communication between the fire extinguisher and a central station for issue of a signal to the central station upon detection of predetermined conditions comprising at least one predetermined internal condition and at least one predetermined external condition, the at least one predetermined internal condition comprising an out-of-range pressure condition of fire extinguishing material contained within the volume of the fire extinguisher tank of the fire extinguisher at the fire extinguisher station said out-of-range pressure condition being indicative of pressure outside of said predetermined range of pressure, and the at least one predetermined external condition comprising at least one of lack of presence of a fire extinguisher in its installed position at the fire extinguisher station and presence of an obstruction to viewing of or access to the fire extinguisher station.

Abstract
An apparatus for remote inspection of fire extinguishers at one or a system of fire extinguisher stations includes, e.g., at each fire extinguisher station: a detector for lack of presence of a fire extinguisher in its installed position at the fire extinguisher station; a detector for out-of-range pressure of contents of the fire extinguisher at the fire extinguisher station; a detector for an obstruction to viewing of or access to the fire extinguisher at the fire extinguisher station; and a device for transmission of inspection report information from the fire extinguisher station to a remote central station.

24. Apparatus for remote inspection of portable fire extinguishers in installed positions at one or a system of fire extinguisher stations each fire extinguisher having contents stored under a predetermined range of pressure, said apparatus comprising:
-
means for detecting lack of presence of a fire extinguisher in its installed position at the fire extinguisher station;
means for detecting an out-of-range pressure condition said of contents of the fire extinguisher at the fire extinguisher station said out-of-range pressure condition being indicative of pressure outside of said predetermined range of pressure; and
means for signaling inspection report information from the fire extinguisher station to a central station, said inspection report information including information from said means for detecting pressure of said contents outside of said predetermined range of pressure. - View Dependent Claims (25)
means for maintaining a record of inspection report information for the fire extinguisher station or system of fire extinguisher stations.
