Brief introduction:<br />This is a perfect helper to protect your house or store. Install the alarm on wall or a door frame / window-frame， and stick the auxiliary magnet part on the door / window (ensure that the two magnet parts touch each other when the door / window is closed). Put the switch onto "on". If any unwanted intruders open your door/window， the two parts will separate from each other， the alarm will send out warning sound， until it is stopped by using the remote control， or fold the magnet strap.
