The YL-333 Magnetic Anti-theft Alarm is a fundamental, battery-powered security device designed for perimeter monitoring. It functions as a standalone, non-connected sensor that emits a loud 90dB alarm the moment the magnetic contact between its main unit and the separate bar is broken, such as when a door or window is opened. This provides an immediate auditory deterrent against intrusion.
Engineered for simplicity and reliability, the device consumes minimal power in standby mode and is activated via a physical switch. Its completely wireless and adhesive-based installation makes it suitable for temporary or permanent deployment in residential, commercial, or vehicular settings without the complexity of smart home integration or wiring.
