ABSTRACT:
An apparatus and method wherein a single sensor assembly will alarm both windows of a double hung window. The single sensor assembly provides a small magnet installed in the upper window sash and a sensor block installed on the lower window sash, said sensor block having a magnet contained in an internal raceway. The single sensor assembly is used in conjunction with a standard magnetic alarm system. The upper window sash magnet repels the sensor block magnet from one end of the sensor block diagonally upward within the sensor block raceway to an opposite end.
