A merchant in Alaska was having difficulty with  false alarm of the Sensomatic  Detection system located at the
 front door of his store.  One of the  Detector  Guard Posts on either side of the door was located too close to the
 product  display shelf.  The sensor on the products located on the shelf would  periodically cause the store
alarm to sound, causing a false alarms and  an  embarrassment to the store manager.  MWT engineers were
 called in to  help design  a protective shield which could be installed on the opposite side  of  the  Sensomatic
Detector Guard Post to eliminate false alarms.  Since the  frequency  of operation of the Sensomatic System is
so low (about 20 to 40 MHz) our standard electrical absorber is not effective. We were able to develop a special
RF shielded fabric which was able to provide the isolation on  the back  side of the Guard Post.  The product is
our MAC-2130-GP Flexible  Absorber  material.  This material is very thin, lightweight and flexible, and can be cut
or custom fabricated into any pattern necessary.
