SHORT
CIRCUIT
ISOLATOR
6202L
1.
INTRODUCTION
Short
circuit
isolator
6202L
is
designed
to
cut
off
(to
isolate)
a
short
circuited
segment
in
a
line
(loop).
In
this
way
the
variable
units
ñ
automatic
fire
detectors,
manual
call
points
and
others,
which
are
not
in
the
short
circuited
segment
remain
active
and
the
line
(loop)
protection
level
is
higher.
Where
isolators
are
not
included,
in
case
of
a
short
circuit
the
fire
control
panel
interrupts
the
power
supply
of
the
line
(loop)
and
all
units
stop
working.
A
segment
is
a
part
of
a
loop
between
two
adjacent
isolators.
