How the System Works
Your 3Mt Library System consists of several
components, including 3Mt Tattle-Tapet Security
Strips, circulation accessories, and the detection
system(s).
The key to the effectiveness of t he system is
protecting your materials with 3M Tattle-Tape security
strips. Only when materials are protected can the 3M
Detection system detect someone trying to leave the
library without properly checking out items.
The primary zone of detection between the lattices
extends from 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 markers you use. The rate of detection
in this area 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 the strips back on when materials are
returned to the library. This allows for full circulation
of all library materials.
The 3M detection system is 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 described in the Accessories section.
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 and
passing 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 f or the
details on the various models.
