Description

Usage: It can be installed on doors and windows, with a switch. When the switch is turned on, if the door or window is opened, it will emit a loud alarm. When you go to sleep at night or are away from home or the office, turning on the alarm switch can help keep your property safe and prevent theft.

Instructions: The alarm consists of a large piece and a small piece. Place the alarm pieces parallel to each other in the middle of the gap between the two windows. The gap between the large and small pieces should not exceed 5mm (you can refer to the packaging for placement). The small piece has an arrow, which should be placed opposite to the arrow on the large piece, parallel to the large piece. If you want to prevent theft, close the windows and turn on the alarm switch. As long as the window is opened (that is, the gap between the large and small pieces exceeds 5mm), the alarm will emit a loud alarm sound, and the owner will take action immediately, capturing the thief on the spot or forcing them to flee.
