The article presents a method of diagnosing the technical conditions of a power amplifier which is used in a sound warning system (SWS). Fire Alarm Systems (FAS) and SWSs are electronic safety systems designed to protect life and health. The FAS is used for effective fire detection, while life-threatening SWSs provide efficient communication of emergency information and evacuation routes via voice. The article presents the problem of diagnosing the technical condition of power amplifiers, which are the essential elements of SWSs. Power amplifiers provide a certain level of undistorted audio (alarm messages) to the speaker set that is arranged in a building supervised by FAS.Keywords: amplifier, audible warning system, working parameter
