PRINCIPLES
OF
OPERATION
The
detector
monitoring
activity
begins
when
a
battery
power
supply
is
connected.
An
information
about
the
detector
mode
is
communicated
by
acoustic
and
optical
signals
as
per
the
following
table:
Detector

Detector

the

x
x
Fault

In
case
a
factor
that
causes
a
particular
mode
decays,
the
detector
automatically
returns
to
its
supervision
mode.
Depending
on
the
type
of
a
battery
used,
the
detector
operation
period
may
vary:
‐
ordinary
batteries
–
min.
1
year;
the
detector
will
work
normally
for
at
least
30
days
since
the
first
low
battery
signal
has
been
transmitted
‐
alkaline
batteries
–
min.
2
years;
low
battery
signal
for
min.
30
days
‐
lithium
batteries
–
min.
3
years;
low
battery
signal
for
min.
60
days.
Frequent
detector
tests
and
its
activation
inspections
will
result
in
the
operation
period
shortening.
