90db Magnetic Door/Window Alarm 2 pack

The 90db Window and Door Alarm is a perfect solution for home security. Secure your home's window, door or even sliding glass doors with the battery operated 90db Window and Door Alarm. Installation is a breeze! Simply peel off the adhesive backing and attach one side of the sensor to the door or window frame and the other side to the door or window itself. Once both sides of the magnetic sensors are separated, this triggers the alarm which will then emit a loud 90 dB sound to notify everyone nearby and scare off any intruders. With the built in on/off switch the owner may open the window or other protected object without setting off the alarm when set to off.
