This product is easy to install. You only need to stick the main unit on the door frame and the auxiliary unit on the door or two windows.
The arrow of the auxiliary unit should be aligned with the mark on the side of the main unit.
When someone illegally opens a door or window (the separation between the main and secondary parts exceeds 10mm), the alarm will sound >90db to warn the intruder to leave. When you want to open doors or windows yourself, you can control them with switches.

The alarm is installed on the door or window. If a thief wants to open the door or window, the alarm will sound immediately.
Just turn off the switch when not in use. The alarm uses magnetic induction control technology, which has a long service life and is simple and convenient to install.
It is pasted with self-adhesive adhesive and does not require screw installation. It can be used by pasting it directly!
No damage to household items! (It can also be installed in the computer case of an Internet cafe to prevent computer hardware from being stolen)

Use:
It can be installed on doors and windows with a switch.
When the switch is turned on, a loud alarm will sound if the door or window is opened.
When sleeping at night or when not at home or in the office, turn on the alarm switch to prevent theft safely.

Instructions:
The alarm is composed of a large piece and a small piece. The large and small pieces of the alarm are attached to both sides of the gap in the middle of the two windows.
The large piece and the small piece are arranged in parallel. The gap between the large and small pieces should not exceed 5 mm (refer to the packaging).
The small item has an arrow, which should be in the opposite direction to the arrow on the large item and affixed parallel to the large item.
If you want to prevent theft, just close the window and turn on the alarm switch. If a thief pushes the window, just open the window.
When it is turned on (that is, once the large and small parts of the alarm are separated by more than 5 mm), the alarm will sound a strong alarm, and the owner of the house will take action immediately, and the thief will be caught on the spot or run away.
