Description

When it senses "shock" or "open" on the window, a loud alarm of about 90 dB will sound for about 25 seconds.
·When the magnet sensor and main unit are at least 1.0 to 1.2 inches (25 to 30 mm), it will continue to ring continuously.
By standing the lock bar, you can prevent the window from opening at least 1.4 inches (3.5 cm).
The thickness is about 0.3 inches (8 mm), so you can open and close the window while it is installed.
The alert mode can be easily turned on and off with a switch.
Battery replacement is not required for about 3 years (when using new Japanese batteries and alarms are confirmed once a week is used.)
