with one or more contact sensors.
6. End of line resistors. Small wires with resistors on them used to reduce
the flow of electricity, indicating the end of a zone.
7. Terminal. A connection point that secures the wires to the alarm panel.
It will often hold each wire in place with a screw or a clip.
Wire nuts or wire connectors. (Not shown) Small plastic pieces

Each alarm panel will look dierent depending on the brand, model,
location of the alarm panel, size of the home, security components,

same components and work the same way. If you are not experienced
in wired alarm equipment modification, we recommend that you consult
a professional.
