PROBLEM TO BE SOLVED: To identify alarm sounds of alarm devices, in an alarm system using existing or general alarm devices. SOLUTION: Alarm sounds produced from sensor alarms (alarm devices) 2 are received by an identification device 1A, and respective sound pressure levels are controlled by an AGC circuit 103. Corresponding control signals CSr are stored in a registration information memory 108. In a monitoring state, when the identification device 1A receives an alarm sound, the sound pressure level is controlled by the AGC circuit 103, and the corresponding control signal CS is collated with the registered control signals CSr to identify the sensor alarm 2.
