DESIGN AND PRINCIPLE OF OPERATION
2.1.
Principle
of
Operation
The
basis
for
the
guard
alarm
operation
is
generation
of
electrical
signals
in
the
sensor
and
at
its
stress
centers
(points
of
the
sensor
rigid
fastening
to
the
fence)
under
mechanical
action
on
the
fence
components
and
their
subsequent
detection
by
the
signal
‐
processing
unit.
2.1.1.
Sensor
The
sensor
mounted
on
the
fence
is
meant
for
electrical
signal
generation
under
unauthorized
mechanical
actions
on
the
fence.
It
is
a
good
practice
to
use
tribocable
as
a
sensor.
The
sensor
length
depends
on
the
guarded
zone
length,
the
fence
height,
number
of
supports,
and
the
selected
way
of
the
sensor
mounting
on
the
fence.
2.1.2.
Signal
Processing
Unit
The
signal
‐
processing
unit
(SPU)
is
used
for
the
sensor
signals
detection
and
the
alarm
signal
generation.
SPU
is
designed
in
the
metal
case.
Located
inside
the
case
is
an
electronic
board
arranged
around
which
are
in
‐
circuit
elements
of
the
signal
‐
processing
unit,
RS485
connection,
terminals
for
the
external
circuits
connection,
and
the
guard
alarm
controls.
Provided
on
the
SPU
case
are
fasteners
meant
for
its
installation.
2.1.3.
Adapter
and
Coupling
The
adapter
is
meant
for
connecting
the
sensor
together
with
its
connecting
cable
to
the
signal
processing
unit
and
for
the
connection
point
shielding
and
sealing.
In
equipping
gates
and
wickets
use
should
be
made
of
an
extended
adapter
permitting
to
fix
a
spiral
wrap
hose
for
the
connecting
cable
protection.
The
coupling
is
used
when
needed
to
connect
two
separate
portions
of
the
sensor
and
for
the
connection
point
shielding
and
sealing.
The
coupling
is
equipped
with
nylon
ties
needed
for
its
fastening
to
the
fence.
2.1.4.
Terminal
Unit
The
terminal
unit
provides
a
continuous
monitoring
of
the
sensor
and
the
SPU
connecting
cable
integrity.
It
is
also
meant
for
the
sensor
end
point
shielding
and
sealing.
