⚡ At a Glance
  • Detection Capability: Dual smoke and carbon monoxide sensors with LCD CO readout and 85 dB audible alarm
  • Best for: Homeowners and landlords needing low-maintenance, continuous fire and CO protection
  • Not ideal for: Properties that require wired interlinked alarms or smart-home connectivity

Combination smoke and carbon monoxide alarm with built-in 10-year battery and clear LCD CO display. Includes test/silence button, visual LED indicators and an end-of-life signal for replacement alerts.


Low-maintenance protection – Thanks to the built-in 10-year battery

A sealed battery and sensor assembly is rated for ten years of continuous operation and includes an End-of-Life (EOL) signal to indicate when replacement is due. Built-in components remove the need for frequent battery swaps.

Minimal ongoing upkeep means fewer missed tests and consistent protection for up to a decade. Homes benefit from long-term coverage without regular battery changes.

Early warning for both hazards – With dual smoke and CO sensing plus an 85 dB alarm

Separate sensors detect smoke and carbon monoxide, triggering a loud 85 dB audible alarm alongside flashing LED indicators. The LCD shows real-time CO concentration once levels exceed 20PPM, while separate red indicators identify the hazard type.

Audible and visual alerts improve the chance of prompt response from occupants. The LCD readout helps verify CO presence rather than relying on sound alone.

Simple DIY setup and daily checks – With battery power, included fixings and a test/silence button

Screws and wall plugs are supplied for ceiling or wall mounting, with a battery-operated design that works during power outages. A Test/Silence button allows weekly checks and temporary muting of non-emergency alarms while the LED continues to flash.

Quick installation suits renters and homeowners alike, and the silence function reduces nuisance alarms without disabling visual status. Regular testing is straightforward and user-friendly.
