Protect your family and meet building regulations with professionally installed mains-powered, interlinked smoke and heat alarms. We fit, test, and certify systems to BS 5839 standards across Flintshire.
Battery-only smoke alarms fail when you need them most. We install mains-powered, battery-backup smoke, heat, and carbon monoxide alarms that are interlinked so if one triggers, they all sound. We position detectors for optimal coverage, connect them to your lighting circuit for reliability, and test the entire system. Our installations meet BS 5839, building regulation Part B, and landlord compliance requirements.
