- Mounting the Alarm:
Clean the surface where the alarm will be mounted. Peel off the protective film from the double-sided adhesive tape on both the main alarm unit and the magnetic strip. Attach the main alarm unit to the door or window frame, and the magnetic strip to the door or window itself. Ensure the two parts are aligned and the distance between them is less than 0.78 inches (2 cm) when the door/window is closed. The arrow on the main unit should point towards the magnetic strip.

- General Alarm Mode:
In this mode, the alarm will sound when the door or window opens and will stop once it is closed again. This is ideal for general security where you want to be alerted to an opening, but the alarm can reset automatically.
Video: Demonstration of the General Alarm Mode. The alarm sounds when the door opens and stops when it closes.
- Constant Alarm Mode:
When set to this mode, the 110dB alarm will sound continuously once triggered by an opening, and will not stop even if the door or window is closed. This mode is designed for maximum deterrence, ensuring the alarm continues until manually deactivated.
Video: Demonstration of the Constant Alarm Mode. The alarm continues to sound after being triggered, even if the door is closed.
- Closing-door Alert:
This mode provides a progressive ‘Di..Di’ sound that increases in volume from 0dB to 110dB as the door or window remains open. It serves as a reminder to close the door or window, ideal for refrigerators or areas where prolonged opening is undesirable.

- Door Open Chime:
In this mode, the alarm sounds a pleasant ‘DingDong’ chime once every time the door or window opens. This is suitable for welcoming visitors or simply being aware of entry/exit in a non-alarming manner.
