Review: Easy like-for-like replacement for 15-y-o ones! - Bought 2 of these to replace the same model that were fitted in the house when built - as they are now 15 years old and had yellowed (shown up somewhat by newly painted ceilings!). The old ones were still working fine, proven frequently when anything thicker than normal went in the toaster, but as these things should be replaced, it was high time. Plenty of screw holes in the base makes fitting a doddle - although I stuck with the original ones and just re-attached into the existing plugs in the ceiling. Cable routing is simplicity itself, with live, neutral and inter-connect terminals in the main connection block and the chassis earth nearby. With the power back on, both units gave a green light for mains feed, and the test button confirmed that the inter-connect circuit was functional. 2 new smoke detectors fitted & working in under 30 mins. All-in-all a quality product that is easy to fit. Free back-up batteries included too.
Review: Replacement smoke alarm - Purchased this hard-wired smoke alarm as a like-for-like replacement for one that was near the end of its life and showing the signs of old age. It comes as a whole unit - mounting plate, detector, back-up battery. It comes with instructions with how to install the whole set-up and to replace the detector. It is straight forward to replace and to test it to check it works - I personally did not replace this myself as it turns out I am not tall enough to reach my ceiling unless I fancied an accident with a step-ladder but I did witness my friend set it up for me and it took him about two minutes once he had read and understood the instructions. However, if you are in doubt about setting this yourself, do get a electrician in to look at it for you - it is never too expensive to ensure your home is protected in the event of a fire. Would I have purchased this particular make and model if I did not already have the fixings in place for this? Difficult to say, but a smoke alarm is a must for your home at the end of the day. It's good to have some peace of mind for the next 10 or so years (and some quiet from the new battery!)

## Questions & Answers

**Q: have aico el141 alarm is it compatable with el141rc as do not want to change base**
A: Contrary to the other answers here, I could not get these to fit, and ended up having to replace the bases too (which, fortunately is a straightforward job). With the old bases removed from the ceiling, one of the two alarms I was replacing could just about be forced on, but certainly not when it was attached to the ceiling.

**Q: Hi there, Does this come with mounting base. The one i am replacing, the mounting base is damaged. So i want the whole unit.**
A: Yes. It comes with a new base

**Q: I am due to replace 2 mains heat alarms model ei144. is it possible to use existing base to replace one with ei141rc mains smoke alarm**
A: Hi. As others have said, the existing base should work fine with the replacements. As far as I know (but I might be wrong!) the triggering of the second alarm if one goes off will only happen if an extra wire (interconnect) is already in place between the two devices.

**Q: Does this fire alarm also detect carbon monoxide?**
A: This fire alarm does NOT detect poisonous carbon monoxide.

### ⭐⭐⭐⭐ Very good smoke alarm which was was easy to replace
*by P***L on 21 June 2021*

We had 2 of these smoke alarms pre-installed in a new build house. They've both lasted and worked well for just shy of 10 years. Have regularly replaced the back-up battery every 12-18m. Touch wood we've been lucky with no real fires, but small kitchen issues have triggered the smoke alarms successfully. For the last few weeks, close to the 10y expiry, the smoke alarms have been temporamental, even with a new battery, and falsely triggering at random times during the day or night. Googling this, it's possbile that the sensory materials inside the smoke alarms have degraded - hence the 10y expiry. Ordered x2 of the same alarms from Amazon due to ease of replacement. Arrived in 2 working days. Easy to replace, no need to remove previously installed base. The new units just slid straight in the old bases, so no need to install and wire up the new bases (you get x2 as spares really). Bonus, the smoke alarms also included a 9V Duracell battery, so no need to purchase new batteries. So far after 1 week no trouble, so will update this review after a few months.
