Why choose wireless

Same level of protection as a wired system, without the disruption of getting there.

Ideal for listed buildings, period properties and occupied homes or offices.

Systems can often be fitted in hours rather than days.

Easily add extra detectors or sounders as your property or business grows.

Interference-resistant, long-range radio signals for dependable performance.

Perfect for tenanted buildings, care homes and busy premises where downtime isn’t an option.

Detectors keep working through power outages, so protection never lapses.
