INTERNAL CONSTRUCTION OF THE MAGNETIC TRIP AND HOW THEY CAN BE EASILY DEFEATED

Magnetic trips are based upon simple reed switch technology, are not secure, and can be easily defeated by magnets, as shown in the video.

Kids and burglars have figured out how to circumvent the system by placing a small magnet next to the trip, which blocks the detection of the absence or the removal of the normal magnetic field that occurs when the door is opened.

Parents in Florida have found that after setting the alarm at night, their kids figured out the way to defeat the system and sneak out at night without setting off the alarm. Likewise, burglars can place very small magnets next to the door trip during business hours within a commercial facility, and then enter after hours. If no other detectors are in place for the protected area, then the door trips will not trigger an alarm.

The magnet that we used in the demonstration cost about $.25 at Home Depot.
