Intrusion Detection Can Work Magic
There is certainly more science than hocus pocus involved in maximizing the accuracy and value of an intrusion alarm system. However, a high level of skill is required for a successful technician or magician, and proper use of sensors and installation methods can produce results no less amazing.
Normally closed (N.C.) alarm contacts should NOT be installed on the ground or common side of an alarm loop. This illustration came from a popular alarm panel manufacturers documentation. It is a good example of how techs need to understand the circuits they are installing.
More Than Meets Eye to Success
Well planned alarm intrusion detection is like magic. As you look at a magician’s act you see two actions. One is the obvious display that is intended for the viewers, the other action is either under the palm, behind the back or concealed in some way. The former is often a distraction for the latter.
When placing intrusion detectors, do it the same way as the magic act. Have the obvious intrusion detector devices in plain view, but have another hidden detection device strategically located. My favorite is a concealed door contact on key interior doors.
