The 5800MINI provides all of the advantages of the Honeywell Home field-proven, quick-install 5800 Series wireless devices, with the addition of signal transmission and low-battery LED indicators. 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. The 5800MINI provides a single zone of protection and installs easily on doors or windows with the included double-sided adhesive tape.
