XCO100 Carbon Monoxide Alarm

Reliable protection against the invisible danger.

XCO100 - The Pyrexx Carbon Monoxide Alarm

The Pyrexx Carbon Monoxide Alarm detects rising concentrations of carbon monoxide and emits an acoustic and visual alarm once a threshold is reached.

Unlike most similar devices, the XCO100 has a unique night mode, dimming the LED light automatically to allow for an undisturbed sleep, without bright or flashing LEDs.

Carbon Monoxide - why we need to worry

Carbon Monoxide is a toxic, invisible, tasteless and odourless gas. Even minute quantities can be fatal. The dangers related to carbon monoxide come from the combustion of flammable materials containing carbon. In our households these combustions typically occur in:

  • open fireplaces and coal-burning stoves
  • gas ranges for cooking
  • oil or gas stoves for heating

Key features: Overview

  • Simple handling. Just like with our smoke alarm devices, the entire bottom cover of the casing has a test/stop function 
  • Lean and inconspicuous design. Just like our other devices the XCO100 aims at being invisible
  • Certified for boats, camper vans and caravans
  • 3 year warranty and a 10 year battery
