Feature

•  Strong penetrating power: Infrasound waves produce a "low-frequency tremor" that causes the body to feel vibrations.
•  High-quality power devices: adopt digital power amplifier as alarm power amplifier to ensure continuous output of sound effects.
•  Humanized setting: the alarm trigger working time is set to 8, and the low-frequency output of 8s-60s is achieved through setting.
•  Small volume: meet the application of different special vehicles.
•  Exquisite appearance: shell material from PA alloy injection molding.
•  Multi-function selection: can be set to choose the independent output of low frequency alarm and high frequency alarm linkage work.
