How Burglar Alarms Work
by Artur Knowles
Leashing a dog outside your house is one traditional alarm.
When the dog sees a person walking near it either act two
ways. First, if the person coming is his master then he will
greet by silently wagging his tail and second if the person
coming is a stranger it will react by barking. This noise
that the dog creates attracts attention to anyone, including
the owner that there is a stranger is nearby. The bark of
the dog is a form of an alarm that stimulates vigilance in
the people within the vicinity.
The Difference between the Old and the New
Dogs and burglar alarms work similarly. First they need a
position to be placed, second they need a trigger to create
an alarm and third they send warning signals by creating
loud noises. The only difference between the two is that
burglar alarms require less management and maintenance
compared to your pet dog.
Where to Place your Alarm
Position the sensors in strategic locations, usually
vulnerable places in the house like the big kitchen windows,
backyard gate or the backdoor. These are locations where an
intruder has a greater chance of entering the house.
Then you have the siren which makes the noise. It must also
be strategically placed in an area where there are no
barriers to the flow of the sound so that the home owner and
other people within the surrounding vicinity can hear the
alarm. The control panel, as its name suggests, has the main
operating button and is also strategically placed in areas
where it is less likely to be seen by the intruder but easy
enough to be located by the owner.
The Guard Dog Analogy
If a person has a plan of breaking in into a house with
security alarm the most possible places that the stranger
would enter are those places where he is likely to be
caught, like back doors and windows. The sensor will detect
the intruders in different ways. If the intruders will pass
through the windows window, sensors will detect the
vibration that the intruder is making by forcing himself
into the house using the window.
Sensors can come in different types as well. Other sensors
like thermal sensors are placed in door knobs and detects
slight thermal changes in the metallic materials of the door
knob, while motion sensors detects the intruders by sensing
the motion made by the intruders.
Ring the Alarm!
As soon as the sensors are activated or tripped, they send
signals in the form of current or radio frequencies to the
siren. When the siren receives these signals it will start
alarming by making loud noises attracting both the attention
of the owner and the intruders. Usually some burglar alarm
systems are connected to a monitoring station usually a
police station. The control panel has the control buttons
which is pressed to stop the alarm.
Burglar alarms usually come as hard-wired or wireless.
Although these alarms may have different models and designs,
burglar alarms works the same way. - 15668
