The GE Personal Security Window/Door Alarm provides a simple-to-use, cost-effective security solution to protect you and your family against home invasions thanks to the 120-decibel alarms, loud enough to make a would-be intruder think twice about entering through your doors or windows. The alarm is also extremely easy to use. The window/door alarms feature a contemporary design with easy access buttons and controls for simple operation. This straightforward concept makes using the GE Personal Security Window/Door Alarm intuitive, no matter what your technological skills may be. The GE Personal Security Window/Door Alarm also includes two independent window/door alarms, each with a built-in 120-decibel alarm for even greater home security. With no wires required for installation, protecting any window/door in your home is as easy as attaching the alarm to your window/door with double-sided tape (included). Each window alarm features an on/off/chime switch for easy operation and a low battery test button for checking battery life. Perfect for homes, apartments, dorm rooms and offices.
