ABSTRACT:
A combined alarm system and window covering assembly includes a top housing, a bottom rail having two ends, a covering, a conductive wire and two resiliently biased reed relay switches. The covering is mechanically coupled to the top housing and the bottom rail. The conductive wire has a first end and a second end and extends from the top housing down to the bottom rail and up from the bottom rail to the top housing. The conductive wire functions as a pull cord for raising and lowering the bottom rail and the covering. Each resiliently biased reed relay switch is mechanically coupled to one of the two ends of the bottom rail and electrically coupled to the conductive wire.
