6.6 Reed Switch Tamper Susceptibility Test Results

  • Entry door – For this test, the Reed switch was influenced by the tamper magnet over multiple test trials. Audible continuity tone showed that the Reed switch contacts closed once the tamper magnet was brought close enough from the outside of the door.
  • Sliding glass door – For the sliding glass door, the magnet was able to make the Reed switch contacts close from the outside of the sliding door. This indicates that the Reed switch can be rendered essentially nonfunctional from a tamper magnet in the mounting scenario shown in Figure 6-7.
