ABSTRACT:
A security screen assembly comprises a screen of mesh material with an optical path formed from at least one optical fiber integrally interwoven with the screen material in a generally serpentine path. A light source or transmitter is coupled to the first end of the optical path while a suitable light detector is coupled to detect light emitted from the second end of the optical path. An interface unit connects the screen to a remote alarm control unit for activating an alarm if the detected light signal falls below a predetermined intensity.
