An extinguisher management system includes a fire extinguisher, a management server and a maintenance server. The fire extinguisher transmits a notification signal when a measured pressure thereof is beyond a predetermined pressure range. The management server includes a wireless receiver for receiving the notification signal from the fire extinguisher, and a database storing an apparatus data set corresponding to the fire extinguisher. The management server outputs an apparatus information in the apparatus data set in response to receipt of the notification signal. The maintenance server is configured to update a to-be-maintained list according to the apparatus information received from the management server.
