electromagnetic
radiation
from
flames
into
electrical
signals
by
use
of
electronic
amplifiers
and
filters,
digital
‐
analog
converters,
a
microprocessor,
and
LED
indicators.
Response
Time
The
IPES
‐
IR/UV
response
time
to
detecting
radiation
emitted
by
test
sources
of
n
‐
Heptane
combustion
in
a
12”
x
12”
(0.3m
by
0.3m)
pan,
and
ethyl
alcohol
combustion
in
a
12”
x
12”
(0.3m
by
0.3m)
pan,
at
a
distance
of
82
feet
(25
meters)
does
not
exceed
30
seconds.
The
sensitivity
and
response
time
can
be
varied
in
order
to
reduce
the
noise
when
the
IPES
‐
IR/UV
identifies
a
fire,
or
the
distance
to
the
probable
place
of
fire
is
short
(“near/far”
and
“slow/fast”
modes).
Can
be
set
using
the
ESP
Commander
program.
Generation
of
Alarm
Signals
The
IPES
‐
IR/UV
incorporates
optical
filters
configured
for
maximum
sensitivity
to
radiation
produced
by
flame
or
fire,
ensuring
rapid
flame
recognition
and
alarm
signaling.
Upon
fire
recognition
within
its
90
‐
degree
field
of
view,
the
IPES
‐
IR/UV
signals
a
change
in
state
from
normal
to
fire
in
any
Original
Equipment
Manufacturers
(OEM)
or
proprietary
alarm
and
response
system.
In
addition,
via
integrated
infrared
(IR)
and
ultraviolet
(UV)
sensors,
the
IPES
‐
IR/UV
monitors
in
specific
regions
of
both
spectral
ranges.
In
the
infrared
spectrum,
the
device
is
configured
for
sensitivity
to
wavelengths
in
the
range
of
4.2
to
4.6
microns,
allowing
optimal
sensitivity
to
combustible
gas
fires
while
rejecting
false
signals
from
incandescent
lamps,
sunlight
and
hot
objects.
For
ultraviolet
radiation,
the
device
is
configured
for
sensitivity
to
wavelengths
in
the
range
of
180
to
250
nanometers,
making
the
sensor
“blind”
to
sunlight
and
radiation
from
heated
objects
but
still
able
to
“see”
the
UV
radiation
emitted
by
a
flame.
With
these
settings,
the
IPES
‐
IR/UV
selects
and
alarms
from
those
characteristic
wavelength
emissions
from
the
IR
‐
to
‐
UV
spectrum
that
indicate
actual
flame
or
fire.
The
analog
signals
from
the
sensors
are
filtered,
amplified,
and
then
converted
to
digital
signals
which
are
then
processed
in
a
microcontroller
via
a
special
algorithm.
This
ensures
the
reliability
of
the
alarm
signals.
The
IPES–IR/UV
takes
the
following
parameters
into
consideration
when
generating
an
alarm
signal:
Magnitude
of
signals
from
different
optical
channels
Ratios
between
the
signal
amplitudes
of
different
channels
Signal
modulation
frequency
Phase
relationships
among
the
channels
