    Replacing a smoke alarm

    Replacing a smoke alarm 10th Mar 18 at 3:44 AM
    Another thick question from me (aka DIY novice) I'm aftraid.

    I have a Aico EI141RC smoke alarm that needs replacing. I could replace with the same product but I know there are others out there that will do the job. What I'd like to do is use the existing mounting base with minimum fuss, ie just slide the unit back in without hammering, drilling etc. Are smoke alarm fittings generally universal?

    You could replace it with the same or similar model from the same manufacturer. Use this link to select your use manual and see the instructions for removing it. Then slide in another one. why do you need to replace it?

    You absolutely must not mix and match interlinked detectors. (And no - pattresses are not universal - they are brand specific.) Incidentally where is this detector located? Ionisation detectors are not the most appropriate in most locations. Generally they are used stumpy because they're cheaper rather than suitable for the location.

    And mine is past it, even though it appears to be working.

    Conclusion: no cutting corners, either replace like with like or change and fit new entirely.

    The model number you show is a mains 230 volt version so the batteries are only for back up and should last quite a long time. You are quite right that they need to be changed as they do have a finite life. However, if you purchase the same model number, it should fit the same mounting base. This will save the hassle of having to remove the old and fit a completely new one, along with the wiring.
