1. An apparatus for remote inspection of a fire extinguisher, the apparatus comprising:
- wherein the fire extinguisher comprises a tank defining a volume containing fire extinguishing material;
a global positioning system receiver located with the fire extinguisher, the global positioning receiver configured to generate location information from signals received from a constellation of global positioning satellites;
an electronic circuit in communication between the global positioning system receiver and a remote central station and configured to issue a signal to the remote central station for at least one of indicating a location of the fire extinguisher and indicating detection of at least one predetermined internal condition and at least one predetermined external condition;
an electrical connection for communicating the at least one predetermined internal condition, wherein the at least one predetermined external condition includes lack of presence of the fire extinguisher as indicated by the electrical connection being disengaged;
a pressure sensor for detection of a pressure condition of the fire extinguishing material contained within the volume of the fire extinguisher tank; and
an ultrasonic obstruction sensor configured to detect an obstruction blocking access to the fire extinguisher, wherein the ultrasonic obstruction sensor is periodically active.

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 communication of inspection report information by wireless signal between the fire extinguisher station and a remote central station.
