The 5800MINI provides all the advantages of the field-proven, quick-install 5800 Series wireless devices, with the addition of signal transmission and low-battery LED indicators. It provides a single zone of protection and installs easily on doors or windows with the included double-sided adhesive tape. It virtually disappears when installed and blends with any décor, making it ideal for applications where aesthetics are critical such as ornate doors, casements and double-hung windows.
