<p>A flexible closure, for use in an alarm system is provided in which a conductive sensing element is interlaced with fibre matrix material to provide a network over at least part of the closure. The interlacing is preferably by means of knitting a conductive wire together with a yarn which forms the matrix of the closure. The closure may further include a protective outer layer on one or both faces of the closure.</p> |
