With Secure Control Units
vandalism is an issue and the need for more features
over a stand alone system are requirements then considering
a reader with a separate control unit is a wise choice.
consideration of using a magnetic reader in this way
is that when a reader is located externally, the swipe
area can be attacked and easily blocked up. The reader
head can also get dirty and this can affect the reading
of the cards. For this application Lock-tec recommend
readers are installed and all electronics are cabled
back to the control unit which is usually located inside
the building in a secure location.
this way, all decisions are made by the control unit
and vandalism of the reader will not compromise the
security of the door. All programming is stored within
the control unit and when a replacement reader is installed
the system immediately reverts to its previous operation.
systems allow up to 10000 users as standard and the
control unit offers the facility to add a second reader
to control in/out access at the door.
