Automatic fire alarm system
The
traditional
electron
safe
alarm
system
mainly
is
through
the
sensor
automatic
detection,
produces the alarm, sends out the alarm the scene
or reports to the police through
the
special electric near distance, thus causes
people's vigilance. Through many years research
and the development, the present alarm
apparatus may say is the class is multitudinous.
As a
result
of
the
alarm
apparatchik
development
and
the
social
each
domain
anxious
need,
can
application domain be more and more
many, specially is overdevelops in the civil
domain.
In
recent
years,
the
infrared
alarm
apparatus
already
became
reports
to
the
police
a
domain
hot
spot,because
it
used
was
not
the
obviously
infrared
acquisition,
Hereford
the
hiding to be good, characteristic and
so on security. Infrared sensor is different
according to
the
mechanism
may
divide
into
the
light
survey
and
the
hot
survey.
The
light
acquisition
sensor
is
uses
the
photon
effect
the
acquisition
aid.
This
kind
of
sensor
speed
of
response
quick,
sensitive
high,
the
examination
characteristic
is
good,
but
needs
cool,
uses
not
conveniently. Moreover the component
examination sensitivity and the infrared wave
length
concern.
The
hot
acquisition
is
uses
hotly
releases
the
electricity
effect
the
acquisition
aid.
After
receives
the
goal
the
infrared
misinterpretation
increment,
the
temperature
elevates
causes
the
censorial
certain
physical
quantities
changes,
through
examination
physical
quantity
change
definite
infrared
emission.
This
kind
of
sensor
works
under
the
room
temperature
condition,
examination
sensitivity
also
very
high,
speed
of
response
also
very
quick,moreover has nothing to do with
with the infrared emission wavelength, may survey
the
power
only
to
receive
the
background
irradiation
limit,
the
application
is
very
convenient.
This article designs atheist passive

With the modern
family use of fire, electricity consumption
increases, the frequency of
home fires
is getting higher and higher. The family of fire,
it is easy to fight does not occur
promptly,
the
lack
of
fire-
fighting
equipment
and
the
presence
of
panic-stricken
people,
to
escape unfavorable
factors, such as retardation, which eventually led
to a significant loss of
life and
property. Explore the characteristics of the
family of fire and fire prevention measures.
For
the
prevention
of
domestic
fires,
reducing
the
fire
losses
have
practical
significance.
In
the modern urban family, because of lot of people
do not understand common sense home
security caused by fire, so that the
happy family Geog underlined blink of an eye, and
some
lead to destruction, but the event
of household fires, improper disposal, alarm delay
is caused
so that people should get to
know more about the main causes of household
fires, master to
prevent
the
fire
of
knowledge
and
in
case
of
fire
to
protect
his
or
her
own
way,
timely
elimination of The
United Kingdom each year more than 50000 families
of serious fires, most
of
them
fire
casualties
and
significant
loss
of
household
assets,
and
some
result
in
the
neighbors, more heavy fire losses.
Investigate the causes of fire in time, the vast
majority of
home fires happen parties
said that the fire always feel that things are
other people with their
own far away,
did not think this will happen even in the top of
his head.
Home fires are the main
reason for negligent not to take timely preventive
measures .In
some of our large and
medium-sized cities, almost every day family
fires, fire prevention is so
each
family
must
always
pay
attention
to.
If
your
home
based
on
the
actual
situation
in
advance to take simple fire prevention
measures, a number of tragedies are entirely
avoidable.
Automaticfire
alarm system is in order to inform the early
detection of fire, and take effective
measures to control and fight fires,
and set in a building or other place of an
automatic fire fac
ilities, is that
people with a powerful tool to fight the fire.
Fire alarm system, fire detectors
ge
nerally, regional centralized alarm
alarm and composition; also be required under the
project
with various fire-fighting
facilities and communication devices linked to
form a central contr
ol system. From
automatic alarm, automatic fire fighting,
evacuation guidance, system proces

shows that, fire up a complete file management,
fire control system. Fire detectors are fire
d
etection devices, as in the stage of
fire will produce smoke with high temperature
flame cells.
The smoke, heat and light
into electrical signals through the detector alarm
or automatic fire e
xtinguishing system
to start fighting the fire in time. Area where the
floor of alarm detector ca
n send the
signal into sound and light alarm, and fire on the
screen showing the room number;
while
also monitoring the concentration of certain
floors of alarm (if the monitor is located
in
the building fire Control Center)
output signal or control automatic fire
extinguishing system.
Concentration of
alarm signal is received by way of sound and light
show, and the screen als
o shows the
specific fire floor and room number, the plane
stopped taking the first alarm clock
to
record the timing, use of the machine-specific
phones, but also quickly to the fire alarm to
give directions and. In addition, you
can control the fire extinguishing system or
signal transm
ission to the fire control
room.
Automatic fire alarm
system is by the trigger devices, fire alarm, fire
alarm devices and
other auxiliary
functions of the device with the composition of a
button fire alarm system fire
alarm
system. It can fire early stages of burning smoke,
heat and light radiation and other
phy
sical quantities, by temperature.
Photographic and other smoke and fire detectors
into electric

the fire alarm controller, and also shows the site
of the fire, the fire re

corresponding device.
(A) of the
trigger devices in automatic fire alarm system,
automatic or manual fire alarm
signal
devices generate called trigger conditions,
including fire detectors and manual fire

of composite. Dif

detectors for different types of fires and
different places. Manual fire alarm

indispensable component of the.
(B) the fire alarm device in automatic fire alarm
system to receive, display and transmit
fire alarm signals, and can send
control signals and control functions with other
auxiliary equi

device instructions. Fire alarm control is one of
the most basic kind. C
harged with the
fire alarm control fire detectors provide a stable
working power; detector and
the working
status of the system itself; the reception,
conversion, processing a warning of fire
detectors Shuck; Jinxing sound and
light alarm; Hashish specific location and alarm
time; the
same time supporting the
implementation of appropriate control and many
other tasks. Fire al
arm system is a
core component. In the fire alarm devices, some
devices such as break, region

monitors, fire shows and other functions can not
complete disc alarm device, which can be
regarded as the evolution of fire alarm
controller or supplement. Under certain conditions
appl
