4-Core Alarm Cable White – 30m Roll | Jaycar

Wiring up door contacts, motion sensors, or a home-built electronics project and you need a cable that handles voltage supply and signal return in one run. This is a white 4-core alarm cable on a 30m roll — enough for most residential sensor loops without waste. It's built for security alarm systems but works just as well for robotics builds, DIY sensors, or any low-voltage electronics where you want clean separation between power and signal.
