Abstract

A fire extinguisher monitoring system is described, said fire extinguisher monitoring system comprising a magnetic member for attachment to a fire extinguisher, a magnet, and a magnetic field sensor, wherein said magnetic field sensor is located proximal to said magnet to detect the presence of said magnetic member in said magnet'"'"'s magnetic field. A method of monitoring the location of a fire extinguisher is also described.

Claims

1. A fire extinguisher monitoring system, said fire extinguisher monitoring system comprising;

a magnetic member for attachment to a fire extinguisher,

a magnet, and

a magnetic field sensor, wherein the magnetic field sensor is located proximate said magnet to detect the presence of said magnetic member in said magnet'"'"'s magnetic field.

2. The fire extinguisher monitoring system according to claim 1, wherein the magnet has at least one line of symmetry.

3. The fire extinguisher monitoring system according to claim 2, wherein the magnetic field sensor is positioned to detect changes in the magnet'"'"'s magnetic field in the same plane as a line of symmetry of the magnet.

4. The fire extinguisher monitoring system according to claim 1, wherein the magnet and the magnetic field sensor are located inside a housing.

5. The fire extinguisher monitoring system according claim 4, wherein the housing is waterproof.

6. The fire extinguisher monitoring system according to claim 4, wherein the housing is weatherproof.

7. The fire extinguisher monitoring system according to claim 1, wherein the fire extinguisher monitoring system further comprises a first processing unit in communication with the magnetic field sensor.

8. The fire extinguisher monitoring system according to claim 7, wherein the first processing unit is in communication with a first alarm.

9. The fire extinguisher monitoring system according to claim 7, wherein the first processing unit is in communication with a transmitter.

10. The fire extinguisher monitoring system according to claim 9, wherein the transmitter relays a signal from the magnetic field sensor to a receiver remote from the transmitter.

11. The fire extinguisher monitoring system according to claim 10, wherein the receiver is in communication with a second processing unit.

12. The fire extinguisher monitoring system according to claim 11, wherein the second processing unit is in communication with a second alarm.

13. The fire extinguisher monitoring system according to claim 11, wherein the second processing unit is in communication with means for recording the status of a fire extinguisher.

14. The fire extinguisher monitoring system according to claim 1, wherein the fire extinguisher monitoring system further comprises a fire extinguisher.

15. The fire extinguisher monitoring system according to claim 14, wherein the magnetic member is attached to said fire extinguisher by an attachment member.

16. The method of monitoring the location of a fire extinguisher using the apparatus of claim 1, comprising;

monitoring the magnetic field using said magnetic field sensor,

positioning the magnetic member for attachment to a fire extinguisher within the magnetic field, and

detecting a variation in said magnetic field caused by the movement of the magnetic member within the magnetic field.

17. The method of monitoring the location of a fire extinguisher according to claim 16, further comprising activating said the first alarm in response to the detection of the variation in the magnetic field.

18. The method of monitoring the location of a fire extinguisher according to claim 16, further comprising activating the second alarm in response to the detection of the variation in the magnetic field.

19. The method of monitoring the location of a fire extinguisher according to claim 16, further comprising recording the variation in the magnetic field.
