Stalwart 72-852075 8 Piece Mini Window Security System Alarm Set (White)

Keep your home protected the easy way. These units use a magnetic sensor to detect the opening of a protected window. A 105 dB alarm will then alert you to an attempted entry and scare off potential intruders. The owner may open the window or other protected object without setting off the alarm by simply flipping the on/off switch. May also be used within the home to alert parents to children opening a gun case, medicine cabinet or use to protect exterior doors, particularly those hard to protect sliding glass doors. Commercial uses include showcases and cash registers.
