Home Security DIY
By installing a home security system yourself, you could save around 50% of the
cost of a professional installing it for you. DIY installations are popular as there
are many home security DIY kits now available from home improvement stores. Installation
is not as difficult as you would think as detailed instructions are provided.
As there is a choice of hard wired or wireless security systems, deciding which
one will influence the installation.
There are a few simple steps to bear in mind before carrying out a home security
DIY installation.
Planning the Layout
Before you think about purchasing and installing your DIY home alarm system, the
most important step to consider is to think about and plan the layout of the various
components of the system. You should draw up a floor plan layout of your property
and this will help decide where to position sensors and the control panel. Pay particular
attention to entry points such as doors and windows. Also note the weaker areas
of the property that could be susceptible to a break-in. This detail will help you
decide the sorts of sensors that are required for your installation together with
what sort of control panel are necessary to control the different zones.
Alarm Control Panel
It would be wise to choose an alarm control panel with expansion capability, if
funds allow. This will provide additional zones which could be utilized in the future.
Next decide on the best position of the control panel. You would usually want this
close to your main entry/exit door for convenience however, if you have a remote
keypad you may want to consider putting the control panel well out of sight. Either
way, it is best to hide the panel inside a cupboard so that a burglar would have
to waste valuable seconds trying to locate it in the event of a break-in. Make sure
anyone that may have genuine reason to enter your house know the location of the
control panel.
Security Sensors
It will need to be decided how and where to mount the sensors within your property
and in the case of a hard wired security system, you need to decide the neatest
and easiest way to run the cables back to the control panel. A hard wired system
may present limitations on where sensors can go and it may not be practicably possible
to always put them exactly where you like. For a wireless system you have far more
flexibility and freedom to install sensors where you like provided the sensors can
communicate back to the control panel.
Siren/Alarm Box
You will need to decide if you would like the siren/alarm box to be visible externally.
Obviously, making it visible acts as a deterrent to would be burglars. However,
you may not want an intrusive alarm box screwed to the side of your property, especially
if it is an older property as it may not be in character with the building. If you
do have a siren/alarm box then plan the installation of the alarm box as high up
as is possible so that it is out of easy reach.
Security System Cable Installation
Make sure that when drilling holes through joists and walls that the diameter of
the hole is large enough to fit many cables through it and keep the cable runs away
from power cables and plumbing. Don’t be tempted to use existing holes that have
power cables running through them – always drill new holes. Only once the cables
are all in place then only consider mounting and installing the control panel, additional
keypad, sensors and siren.
Always leave a few feet of cable spare when running cables to each sensor position.
The slack can be pushed back into the ceiling. Use 6 or 8 core alarm cable as most
PIR sensors require 6 wires: two for power, two for the 24 hour tamper loop and
two for the alarm loop.
In contrast the magnetic door switches doesn’t need power to 4 core cable will do.
Two for the alarm loop and two for the 24 hour tamper loop. But, it’s still worth
using the higher core cable as you may want the extra cores in the future.
The siren generally uses six cores: two for power, one for the strobe, one for the
siren trigger and two for the 24 hour tamper loop.
As door contacts can only detect a door or window being opened you may want to consider
installing shock sensors. These will need to be fitted to an area of your property
that can be accessed through forced entry like a window frame or door. If you think
force entry can be gained through kicking a panel or breaking a window it is worth
installing shock sensors instead of door/window contacts. Door contacts are typically
fitted to external doors but could be fitted to any vulnerable door or window.
