The Kidde carbon monoxide alarm protects against the silent killer - CO gas. Neat and tidy, the 900-0259 CO alarm comes complete with batteries, LED, 5-year warranty, low battery indicator bleep and is BSi Kitemarked to BSEN 50291:2001. It is also portable and will stand on a surface. Kidde makes 30 million detectors every year and you won't get better than this.

The 7-year version takes standard AA batteries which will need replacing periodically and is ideal for the home. The 10-year version comes with a sealed lithium battery which will last as long as the alarm, and is perfect to prevent tampering.

Use the drop down menu on the side to select either the 7 or 10 year warranty carbon monoxide alarm - ONLY the 10 year version is compliant with new 2022 Scottish regulations. 

Suitable for any premises where people sleep or live

    I liked the fact that you sold single lengths of fire seal and not just packs. I chose you on that score above other competitors
