Genesis of Resideo offers a very high-quality product with their 18-gauge, 4-conductor stranded cable. This 1,000 foot cable is perfect for DIY and professional installers looking to achieve strong results for their projects. This is great wire to have on hand for almost any situations.
Most alarm system installers choose 18-gauge wire due to its superb flexibility and its relatively long wire run capabilities. Of course, you can choose a slightly thicker wire to increase the maximum run distance. Likewise, you can select a thinner wire to increase installation flexibility. But 18-gauge wire really provides the best of both worlds.
The reason this wire is referred to as "4-conductor" is because of the four smaller inner wires house inside the larger cable. There are a few hardwired security products that rely on the four connections offered from 4-conductor wires. The most notable of these products include most wired keypads and 4-wire life-safety sensors.
Keep in mind though that the majority of standard security sensors will only need 2-conductor cabling. You can use 4-conductor wiring with 2-conductor devices, as you can just leave two of the internal wires disconnected. However, this can appear sloppy and unprofessional. You should avoid doing this, as completing each connection is best practice.
The inner wires for Genesis Cables are built from copper. This construction helps the wires transmit both data and power almost seamlessly. The two cables are color-coded black and red respectively. Black signifies negative, and red signifies positive in most situations.
Note: This is unshielded cabling.
