BEP Piezo Buzzer - 42mm - 5-20V - 97DB

The BEP Piezo Buzzer – 42mm – 5-20V – 97DB is a high-output audible alarm component engineered for tactical, maritime, and emergency response applications where reliable notification is essential. Built by BEP Marine, a trusted manufacturer in marine and industrial signaling, this piezo buzzer delivers consistent, attention-grabbing sound across variable power supplies—essential for vehicle backup alarms, breach notifications, and perimeter security systems.

Law enforcement and military teams rely on piezo-based alerting devices because they function reliably in harsh environments, require no moving parts, and operate across wide voltage ranges typical of field equipment and vehicle power systems. Piezo buzzers use piezoelectric ceramic discs that vibrate at high frequency when voltage is applied, generating sound without a traditional speaker diaphragm—this eliminates mechanical failure points and ensures durability in shock, vibration, and temperature extremes.

The 97dB output at rated voltage provides immediate acoustic presence sufficient to cut through ambient noise in tactical operations, vehicle interiors, and outdoor environments. The 42mm form factor balances compact installation in tight equipment spaces while the 5-20V input range accommodates standard vehicle alternator output (12-14V nominal), battery banks, and field power supplies without requiring voltage regulation, reducing circuit complexity and failure points in the field. This buzzer suits emergency response teams and outdoor enthusiasts alike, ensuring reliable alerts in critical situations.
