securitywarehouse Posted February 23, 2011 Author Share Posted February 23, 2011 I also needed to know...... These sensors are listed as Grade 3. What does Grade 3 Mean? Quote Link to comment Share on other sites More sharing options...
stuart_mcg Posted February 24, 2011 Share Posted February 24, 2011 The hint is in the title : "Viper GLX SENSOR WHITE GRADE 3" As far as grades are concerned, please look up the European standard for all the definitions. EN50131 European Standards For Intruder Alarm Systems Grade 3 is for a reasonably substantial risk property. There is good reason to assume it may be broken into and might well contain objects of high value. An intruder is likely to gain access by penetrating doors, windows or other openings. The thief could be very experienced with intruder alarm systems and possess a number of tools and equipment to overcome the system Cheers, Quote Link to comment Share on other sites More sharing options...
