Review: Brilliant - Very good Well made detector Good size you can stand on unit or mount on the wall with easy to follow fitting instructions Lights on front flash to let you know all is working ok and if there is a fault Really good value for money Comes with batteries and easy to follow instruction
Review: A must have - Good bit of kit to offer that piece of mind. Our boiler is in a cupboard in my daughters room so having a good carbon monoxide alarm is essential to me. Simple to install with detailed but clear instructions. You have the option to mount (fixings supplied) it or simply free stand in a convenient spot. Very easy to test that sound on the alarm is working as it should, much like a smoke alarm you simply press and hold the button. There are lights on front which flash to tell you it is working or if there is a fault. It runs on two AA batteries (supplied). An important device to have which I highly recommend.

## Questions & Answers

**Q: Does this meet the Scottish 2022 updated legislation as I notice it has three batteries rather than built in?**
A: No, this does not meet the new Scottish legislation as these have replaceable batteries. You need to have a carbon monoxide alarmed with a sealed-in battery and we would suggest you purchase either the Kidde 10LLCO alarm or the Kidde 10LLDCO alarm which both have sealed-in battery and will last for the duration of the alarm. The battery is also covered as part of the 10 year warranty which is valid from the date of purchase.

**Q: What is the decibel rating for the alarm please?**
A: 85 decibels and this is also stated in the instruction manual

**Q: Hi , is this alarm comply with Bs 50291 ? Thanks**
A: Hi the answer is Yes it stamped BS50291 so it seems to comply

**Q: Does this unit comply with bs en 50291 standard?**
A: As per advert on Google for this unit it states - Kitemarked to BS EN 50291-1:2010 and CE marked, 7 year warranty.

### ⭐⭐⭐⭐ Good product, worth the money!
*by A***S on 29 November 2025*

Easy to install, comes with a clear set of instructions to test and set up your alarm (3beeps followed by another 3 beeps followed by 1 beep during test and you will see a green indicator every 30 seconds in Operate Mode). Recommended to test it every week to ensure its in a working condition It can be mounted on a wall or ceiling or can be free standing too. It comes with AA batteries. I would highly recommend to people looking to buy a CO detector. Worth the money . I would say that the safety level is quite high . The packaging was nice as well and easy to open. The noise level is good , loud enough to hear as well. The brightness was not too bright either . It look really nice to look at and works well too.
