Special Features
High-Volume Audible Alert for Multi-Purpose Use: Emits a loud, continuous car alarm-like tone (up to 85-100dB) that is clearly audible from several feet away—even over engine noise. Ideal as a door chime, dog deterrent, or warning device for vehicles, boats, or industrial equipment. Operates effectively at 3-24V DC, with peak volume at 12V DC
Flexible Sound Customization & Voltage Compatibility: Includes simple volume control options: add resistors, cover the outlet with tape, or wrap the unit to reduce sound. Compatible with PWM signals and variable voltage inputs (3-24V DC), allowing precise tuning for indoor/outdoor applications
Durable, Flame-Retardant ABS Construction: Housed in high-temperature-resistant ABS plastic with anti-aging and wear-resistant properties. Robot-welded circuit boards ensure no cold soldering, false connections, or silent failures—guaranteeing long-term reliability in harsh environments
Easy Low-Voltage Integration & TTL Compatibility: Designed for straightforward wiring into existing circuits (TTL-compatible), with pre-soldered PIN pins for quick installation. Model YMD-12095 operates at a rated voltage of 5V DC but performs reliably across its full voltage range (3-24V DC)
Versatile Replacement Solution for Failed Alarms: Functions as a reliable substitute for piezo speakers in alarm clocks, motorcycle horns, turn signal alerts, or boat safety systems (e.g., temperature/oil pressure alarms). Easily extends alarm coverage across large spaces like multi-story homes or workshops
