An alarm lock is a heavy-duty, anti-theft security device combining a traditional padlock with an integrated, motion-sensitive siren, typically emitting a powerful 110dB sound to deter intruders. Constructed from durable materials like aluminum alloy or hardened steel, it is designed for both indoor and outdoor use, often featuring weather-resistant and waterproof capabilities. The device features a dual-locking mechanism, allowing
it to function in alarm mode or as a standard lock. When tampered with, shaken, or broken, the alarm activates immediately. It is ideal for securing bicycles, gates, motorcycles, and sheds.
