Item #: YL-323. Lot of 3. At only 2 1/2 inches long, the world's smallest window alarm inconspicuously protects your home from intruders. This unit uses a magnetic sensor to detect the opening of a protected door / window. A 90 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 turn the switch to "OFF". 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 show cases and cash registers. 3 LR44 cell batteries and double sided adhesive tape included. With On/Off switch. Measures 3" x 1.75" x 0.75" . Weights 1.5 oz.
Note: No warning sticker is supplied in the package (the manual gives wrong info.)
