2-5 Chapter 2: The LC1400T
Perimeter Mode Control
Perimeter mode is configured to be controlled
by hardware. Perimeter is active by the
Perimeter input (
Perimeter ) being held high.
Positioning
The recommended location of the LC1400T is
on the wall next to the latch side of the door.
Its lowest point should be about 2 feet above
the floor.
Mount the LC1400T inside the intended
monitored area.
Mount the LC1400T so its interior ferrite bar
(figure 2.2) is positioned at least 3 inches away
from any type of metal, including:
• Metal door frames
• Metal studs
• Metal lathe walls
• Metal electrical box
• Metal conduit
• Metal pipes

In addition, the LC1400T should be positioned
within 3 and 18 inches of the monitored door
or elevator to assure proper coverage. The
recommended distance is 3 to 6 inches.
If the Controllers of adjacent zones are closer
than 50 feet, implement Stagger Tuning to
avoid crosstalk (activated Tags from one
zone being detected in another zone). See the
Stagger Tuning section of this chapter and
chapters 8 & 9 for information on stagger
tuning.
Positioning the LC1400T correctly will help
avoid unintended activation of a tag in a
nearby room or on a passerby. The goal is to
produce a Tx activation field that adequately
covers the doorway but does not extend into
nearby rooms
