Alarm Wire
What You Need to Know
There are many components to an alarm system and one such component is wire. Even if you have a wireless system, wire can still play a part in getting the job done. (For example, you could choose to use a transformer with wire that attaches to your control panel.) But for the sake of this discussion, let’s talk about DIY wired alarm systems.
When you are picking out your wire it will likely be more convenient to buy wire packages that are rolled and wrapped tightly within plastic. This makes it convenient so that you can store, carry, open, and roll out the wire as needed. A label should also be on the package indicating how many conductors (wires) there are and the gauge.
Typically a sheath covers 2 or 4 wires which are then stripped during installation. It is important to note that door and window sensors require two wires, while motion detectors require 4 wires (2 for power and 2 for circuit).
You should also consider the gauge of the wire. The gauge of the wire is the thickness of it. The higher the number of the gauge the smaller the wire will be. Typically for sensors you will use 22 gauge wire (though some transformers and sirens may call for 18 gauge wire).
Okay, now it’s almost time to buy your wire, but what you must know first is how much to buy. To do this, measure the distance along the wall (or under the carpet) from the areas you would like to protect to where the control panel is positioned. The total distance is the minimum requirement of how long you will need your wire to be.
There are many needs for wire and many devices that cannot work without wires from keypads to smoke detectors. Plus, don’t forget about wire accessories which will help in your DIY endeavors such as wire connectors and harnesses. Good Luck!
