The Basics About Alarm Security
The Basics About Alarm Security
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I decided to write an article on Burglar Alarms,
describing
exactly how they are wired up and how to bypass the system
so that you don’t
get caught.
They use a variety of items to catch thieves, they include
PIR’s,
Door Switches, Sirens, Police Autodiallers, Bells etc.
PIR’s – Passive Infra Red –
Designed to comb an area of the
property from intruders.. they send out beams that comb the
area.
anybody walking across the beams when the alarm is set will
trigger the alarm off.
There is a weakness with these that if
you walk directly at them 99% of the time they won’t
trigger
off the alarms.
Door Switches – These are put on doors for security
purposes
incase they try and break in through the door. These switches
are Normally
Close (NC) Switches, so if you break in you also
trigger the alarms because the switch flips
telling the control
panel that some cunt is breaking in.. Some Door Switches are on
a
timer For Entry/Exit (more about this later).
Sirens – Designed to be as noisy as
possible usually 114 Db
the other aim of the siren is to draw attention to the fact
that
something is wrong, at night you can here a siren from a
long distance.
Police
Autodialler – This little bastard calls the police about 4
to 10 secs before the alarm goes
off, it sends a pre-recorded
message to the local police station, there are various ways to
Bells – the aim is the same as for a
siren usually about 118 Db
How to bypass Alarm Systems
~~~~~~~~~~~~~~~~~~~~~~~~~~~
You will need at least 2 – 3 people when doing a job where
there
is an alarm system…
The best way to enter somewhere is through the main
door.
WHY !!!!!
Because the main door will be on an Entry/Exit timer to allow
people to come in through the door put bags etc down get right
key etc.. so they always set up
a timer usually about 10 – 20
secs….
This gives you time to :-
1 –
Disable the autodialler by either Cutting the Autodialler
wire or unscrewing it pulling the
telephone wires out and
disconnecting the mains and battery.
Whilst someone is
turning the autodialler off and the other
person is Disabling the Control Panel, the other
person
should disable the bell, To do this is easy push the bell up
and it should
dislodge from the base unit,, get abit of tape
and at the bottom of the base plate is a Micro
switch tape this
shut so that when you take the bell box lid off you trigger
off any
alarms.. then simply disconnect the bell from its holding
2 – Pulling the siren
off the wall.
3 – Unscrewing the control panel + disconnecting Mains Power +
Not
forgeting to take the Battery out.
ADDED INFO ABOUT CONTROL PANELS + BELL
BOXES.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Control Panels are protected
from tampering by 2 things
1 – The panel screw.
2 – A Micro Switch
located at the edge of the control lid , so
if the alarm was set and you just opened it it
would set all
the alarms off.. so leave it to the end.
Bell Boxes are protected
in exactly the same way as the above..
Wiring Details for Alarm Systems
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Switches usually have 4 wires for the alarm + 2 for
Anti-tamper
They are wired up in series that is in 1 big loop.. for one switch
ust use the 4 wires as normal but if you wish to connect more
switches you just cut 1 of the
alarm wires so that their are 2 ends
and connect it to the switch doing the same for the
Anti-Tamper
thus producing 1 continuous loop.. The front door switch though has
its own
wire because it goes to the entry exit circuit on the panel
all the other switches are either
on zone2 or zone1..
PIR’s usually have 6 wires:-
2 for alarm 2 for Anti
Tamper and 2 for the power supply
The wiring up of more than 1 pir is the same as for switches
that
is the alarm is in series as is the Anti-Tamper, BUT the power is
wired up in
Parallel that is there is no break in the wire just
splice back the covering and attach
another wire to it..
