Using magnetic affinity to initiate its 110db siren, this door and window alarm will alert you when ever a sliding door or window is opened.

The magnetic base of the alarm screws to your frame while the alarm actuator connects to your door or window.

When the door or window is closed, the magnets are connected. If the door or window opens, the magnetic contact is broken and the alarm will sound. Simple but effective home protection.

Provides alarm security to windows, doors, or potential dangerous closets and cabinets in the home.

Great for any door or window, particularly those hard to protect sliding glass doors (patio). Requires 3 lithium button cell batteries (included).
