BEP 54-27C4 Piezo Buzzer 30mm 5-30V 85dB

BEP Marine 30mm Piezo Buzzer 5–30V DC (85dB)

The BEP 54-27C4 ( retail display SKU 54-27C4/DSP) is a compact, high-output 30mm piezoelectric sounder / acoustic alarm designed for primary status signaling, system fault alerts, and high-water or engine-warning notifications across marine DC electrical installations.

Operating across a wide input range of 5 to 30V DC, this sounder produces a clear single-tone acoustic alarm reaching up to 85 dB. Designed for low current draw (~ 9 mA @ 12V DC), it is ideal for integration with CZone digital switching circuits—such as the 701-MDCZ motorized battery switch—as well as standard BEP switchboard panels, engine gauge alarms, and bilge monitoring circuits.

Key Features

• High Acoustic Output: Generates a loud 85 dB single-tone alert at 9V DC to penetrate engine noise and wind sound in helm environments.

• Ultra-Low Power Consumption: Draws only ~ 9 mA at 12V DC, preserving battery power during extended alarm conditions.

• Wide Voltage Range: Compatible with both 12V and 24V DC marine electrical networks without requiring external voltage drop resistors.

• Solid-State Reliability: Piezoelectric design eliminates mechanical contacts, providing high vibration resistance and long operating life.

• CZone & Standard Panel Integration: Specifically suited for driver output triggers on CZone modules, motorized battery switches (701-MDCZ), and standard dashboard alarm loops.
