BL-8513 Magnetic Anti-theft Alarm Device for Door/Windows
BL-8513 Magnetic Anti-theft Alarm is a security alarm system that is easy to use and install. It runs on two AAA batteries and works by detecting magnetic contact. When the small part of the alarm separates from the main unit, it produces a loud sound (90dB) that can deter intruders or alert guards. When the parts are reattached, the sound stops. BL-8513 Magnetic Anti-theft Alarm system is a portable and affordable device for various purposes.
Working Principle: The alarm has an On-Off switch that allows you to activate or deactivate it as needed. No wiring is required for installation, so the alarm cannot be easily disabled by strangers once it is triggered.
To test the setup, switch the system’s switch to the “ON” position on the main unit and open the door/window to see if the alarm goes off.
Note: The package does not include batteries because they are not allowed by Air-Cargo.
