Professional Interlinked Detector Systems Across the UK

Blaby Fire, part of Blaby Group, provides professional interlinked smoke and heat detector systems for residential, multi-occupancy, and commercial properties. Interlinked detectors enhance early warning, occupant safety, and regulatory compliance by ensuring that when one alarm activates, all connected alarms sound simultaneously.

Our solutions are tailored to each property’s layout and risk profile, installed by qualified engineers, and supported with ongoing testing and maintenance contracts for peace of mind.

Our Interlinked Detector Services Include:

  • Interlinked smoke detector installations
  • Interlinked heat detector installations
  • Mains-powered detectors with battery backup
  • Wireless and hard-wired interlinking
  • Full installation, testing, certification, and ongoing maintenance

What Are Interlinked Detectors?

Interlinked detectors are smoke and heat alarms connected so that activation of one unit triggers all alarms within the system. This provides earlier warning across the property, particularly in larger homes, multi-storey dwellings, and high-risk areas.

These systems are widely required under UK building and fire safety regulations, including:

  • Building Regulations Part B (fire safety)
  • Guidance for multi-occupancy dwellings and high-risk residential properties

Smoke & Heat Detectors

Blaby Fire installs a combination of smoke and heat detectors to suit each property’s layout and risk assessment:

  • Smoke detectors – for circulation spaces, living areas, and bedrooms
  • Heat detectors – for kitchens, boiler rooms, and other high-risk areas

Detector type, placement, and interlinking are carefully designed to ensure effective detection while minimising false alarms.

Hard-Wired & Wireless Interlinking

We install both:

  • Hard-wired interlinked systems – permanent, reliable installations suitable for new builds or major refurbishments
  • Wireless interlinked systems – ideal for retrofits or where minimal disruption is required

All systems are installed in accordance with BS 5839-6:2019 for fire detection and fire alarm systems in domestic premises, and BS 7671 wiring standards where applicable.

Ongoing Testing & Maintenance

Blaby Fire offers comprehensive maintenance contracts for interlinked detector systems, including:

  • Regular inspection and functional testing to ensure all devices operate correctly
  • Battery replacement, fault diagnosis, and repairs for wireless or mains-powered units
  • Full record-keeping, certification, and reporting for regulatory and insurance purposes
  • Support for tenant safety and property compliance audits

Ongoing maintenance ensures your interlinked detectors remain fully operational, compliant, and ready to protect occupants at all times.

Safe & Compliant Installation

All interlinked detector installations are:

  • Carried out by qualified engineers
  • Fully compliant with BS 5839-6:2019 and relevant UK building and fire regulations
  • Tested and commissioned on completion
  • Supplied with certification and documentation for audit and insurance purposes
