Home safety alarm designed to detect carbon monoxide and show current levels on a digital display. Families and households with vulnerable occupants gain reassurance from clear readings and audible warnings with Safeliveo Carbon Monoxide Detector. Is it the sensible choice for everyday home monitoring?

⚡ At a Glance
  • Detection Accuracy: 10-year electrochemical sensor detects from 10 ppm, issues low-level warning at 20 ppm after 35 minutes
  • Best for: Households with children, pregnant women, the elderly, or anyone needing portable room monitoring
  • Not ideal for: Large open-plan spaces exceeding 40 square metres where a single unit cannot cover the area

Compact detector shows live CO readings on an LCD and sounds an alarm louder than 85 dB when levels become dangerous. Replaceable AA batteries power the unit and a 10-year electrochemical sensor supports long-term monitoring.


Early warning for vulnerable occupants - with low-level CO alert at 20 ppm

A low-level warning triggers when carbon monoxide concentration reaches 20 ppm and persists for 35 minutes, activating a visible and audible alert. The digital memory function records alarm events for later review.

Useful in bedrooms and communal areas where small, sustained rises in CO need attention, allowing timely action for children, older adults and those with respiratory problems.

Long-term reliability - with a 10-year electrochemical sensor

An electrochemical sensor rated for a 10-year lifespan detects dangerous carbon monoxide concentrations and initiates the audible alarm rapidly. Sensor chemistry maintains detection stability over the stated service life.

Minimises the need for frequent sensor replacement and delivers steady monitoring over many years, reducing maintenance effort.

Clear readings and flexible placement - with a digital display and compact size

Digital display shows the current CO level with a minimum reading of 10 ppm and the unit measures 60 × 105 × 32.7 mm for unobtrusive placement. The detector can sit free-standing or be wall mounted using the included screws.

Straightforward numeric feedback makes it easy to see rising CO levels, while small dimensions suit hallways, kitchens and portable use around the home.

✨ The 4 Key Reasons for Safeliveo Carbon Monoxide Detector
  1. 10-year electrochemical sensor - Keeps reliable CO sensing without frequent sensor replacements.
  2. Digital display with memory alarm - Shows current readings and stores recent alarm events.
  3. Replaceable AA batteries - Simple swap power lasts about one year per set of batteries.
  4. BS EN 50291 compliance - Audible alarm louder than 85 dB for unmistakable alerts.

❓ Frequently Asked Questions

Q: How long do the batteries last?

A: Two replaceable AA batteries power the detector and last around one year per set according to the manufacturer description.

Q: What CO levels trigger an alarm or warning?

A: The digital display shows levels from 10 ppm upwards; a low-level warning occurs at 20 ppm if that concentration persists for 35 minutes, and a loud audible alarm and red LED flash signal dangerous concentrations.

Q: Can the unit be wall mounted?

A: Yes, the compact detector (60 × 105 × 32.7 mm) can sit free-standing or be wall mounted using the supplied screws.

🏆 Our Verdict

Suitable for households that want straightforward, reliable carbon monoxide monitoring, especially where vulnerable people live. Clear numeric readings, a low-level alert and a 10-year electrochemical sensor deliver steady long-term protection. Replaceable batteries and end-of-life warnings help keep maintenance simple and reduce lifetime running costs.
