Internal reinforcement and alarm mesh for protecting building

摘要

The mesh is assembled from individual construction rods of U-shaped profile made of high quality steel. The U-profile frames have an internal width corresponding to standard door and window sizes, for acting as parts of the door or window frame and can be fitted with metal reinforced, non-breakable, clear plastics panels. The profile frames incorporate an electronic circuit responding to attempted breakage of the clear plastics panel to trigger an acoustic and/or optical alarm, with emergency opening in the case of a fire, etc. permitted.
