Is the Boundary alarm system wireless?

All Contact Sensors that fit on door or window frames, as well as the Motion Sensors, are wireless. They use long-life Lithium-Ion batteries that will last for up to two years. The Outdoor Siren is also wireless and again uses long-life batteries to ensure you have an easy, wire-free installation.

The Hub requires a standard 240v plug for power and also includes a battery providing 12 hours of continuous backup should the power fail. It is, of course, possible to provide mains power to the unit directly from a cable within the wall. It is a requirement to meet a grade II level specification that the Hub uses mains power and has a battery backup. The unit will also have the ability to detect if mains power is cut deliberately or through a power failure.
