The owner may open the window or other protected object, without setting off the alarm by inserting a deactivation key. Once the deactivation key has been removed and the protected door or window is opened, the alarm will sound until the key is inserted or the door or window is closed.
Inconspicuous alarm for showcases, cash registers, gun cabinets, medicine cabinets, or sliding doors. With it's low price, you can easily afford as many as you need.
