Introduction
Model 3500/3800
Section 1. Introduction
People who remove materials from libraries without
authorization are much like your average patron. Li-
brary materials are usually placed within book bags,
briefcases or concealed under clothing. 3M detection
systems have been designed to detect the unauthorized
removal of materials concealed in this manner. While
a 100% electronic net does not exist, the 3M system
provides effective protection and significant reduction
in the loss of library materials.
With a little attention and care, your 3M system
should provide you with many years of service and
help to protect your library against thousands of dol-
lars in losses.
Call our toll–free 800 number any time of day or
night for service, to order supplies, or to leave mes-
sages for your sales representative:
1–800–328–0067
