A system for notifying when a fire extinguisher is discharged or moved uses a device mounted on the fire extinguisher for monitoring one or more conditions. For example, the device may be interconnected with a trigger detecting mechanism otherwise present on the extinguisher or sense a sudden drop in pressure to detect when the extinguisher is activated. An accelerometer may be provided to detect motion. GPS processing can identify the location of the fire extinguisher when an event occurs. When the device detects a change in one or more of the conditions, or needs to send periodic updates of the fire extinguisher conditions, a message is forwarded from the device to a third party clearinghouse via a wireless communication network. The clearinghouse reviews the data, and forwards the data, as may be appropriate, to one or more authorized parties identified in the database.
