This magnetic contact window door alarm, at only 2 1/2 inches long, inconspicuously protects your home from intruders. This unit uses a magnetic sensor to detect the opening of a protected door and window. A 110 dB alarm will then alert you to an attempted entry and scare off potential intruders.

This gadget may also be used within the home to alert parents to children opening a gun or medicine cabinet or used to protect exterior doors, particularly those hard to protect sliding glass doors. Commercial uses include showcases and cash registers.

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.
