Alarm/Siren

High sound pressure level alarms are designed using piezoelectric ceramic discs combined with resonant chambers, delivering sound pressure levels exceeding 120 dB(A). At the core is a highly efficient piezoelectric material that generates sharp, penetrating alarm tones through high-frequency vibration—ideal for noisy environments. These alarms feature weather resistance and a compact structure, making them widely used in fire safety, security systems, and industrial equipment for urgent warning applications. They provide reliable long-distance coverage but generally consume higher power and require dedicated driver circuits for optimal performance.
