Section 3. How the System Works
Your 3M Detection System consists of several
components, including 3M Tattle-Tape Security
Strips, circulation accessories, and the detection
system(s).
The key to the effectiveness of your system is
protecting your materials with 3M Tattle-Tape security
strips. Only when materials are protected can your 3M
Detection system detect someone trying to leave your
library without properly checking out items.
The primary zone of detection between the lattices
extends from the surface of the floor to 72 inches
[1,82 m] above the floor. The electronic coverage in
this area is not 100% and it will vary with the options
you have and the type of 3M security strips/markers
you use. However, the rate of detection from the
surface of the floor to 72 inches [1,82 m] above the
floor is effective to deter the loss of protected
materials.
Checking out materials is accomplished using
desensitizers to “turn off” the strips while resensitizers
are used to “turn on” the strips when materials are
returned to the library. This allows for full circulation
of all library materials.
The 3M detection systems are designed to detect
sensitized 3M Tattle-Tape security strips and then
sound an alarm, thus preventing unauthorized removal
of library materials.
It is this simple:
Mark materials as described in this manual.
Circulate materials using desensitizers and
resensitizers.
Listen for the 3M detection system alarm to sound
when unauthorized removal of materials occurs. Of
course, it is also important to watch for suspicious
actions such as holding materials above the head or
moving items around the lattices when passing
through the detection system.
3M offers several models of detection systems to meet
your library’s needs. See the next section for details
on the various models you have.
