What is the purpose of using 18/1 wire in burglar alarm installations?

Using 18/1 wire in burglar alarm installations primarily serves the purpose of grounding the alarm panel. Grounding is a crucial aspect of alarm system integrity as it helps to eliminate electrical noise and ensures that the system operates reliably. Proper grounding protects sensitive components of the alarm system from power surges and lightning strikes.

While other options might seem viable, they pertain to different functions that require different wiring specifications. For example, connecting sensors typically needs a wire gauge that accommodates the signals transmitted from the sensors, while providing power to the panel may require a heavier gauge capable of handling the power load. Communication with the monitoring station usually involves different protocols and wiring tailored for data transmission rather than simple grounding. Therefore, using 18/1 wire is specifically aligned with ensuring effective grounding in a burglar alarm system installation.
