Patent GB-2038060-A (GB)
Title: Intruder alarm
IPC: G08B13/12
Filed: 1978-10-24
Abstract: The need arises, in security systems, to protect a room, with the intruder detection arrangement inconspicuous. For this purpose, a wall to be protected has embedded in it a mesh of optical fibres with the fibres arranged in a reticulated pattern. Each fibre has a light source at one end and a light detector at the other end. Thus when the wall is breached, one or more fibres is broken, and the cessation of light flow in such fibres is used to give an alarm. If the light sources used are lasers, so as to supply coherent light, the malefactor's efforts to breach the wall modulate the light, which modulation is also used to give an alarm. The arrangement can also be used to protect the fencing of protected areas: in this case the mesh has strength members and is incorporated in or actually forms the fence. <IMAGE>
