The W-1000 (flush mount) and W-2000A (surface mount) door boxes are designed to be installed on the unused telephone line input of nearly any phone system. One or two door boxes can also share an existing residential phone line and provide door strike and CCTV camera control when used in combination with a C-1000B door box controller. When the âCallâ button is pressed, the door box generates a standard ring cadence for an adjustable number of rings.
