  1. In short:

    A D2 system is mains powered with user changeable standby batteries.

    An F2 system is only battery powered. (with user changeable batteries)

     

    I would suggest you get another quote as although "wireless" systems are quicker to install and the installation process is less disruptive they can be more expensive than a wired system, also there is the ongoing cost of batteries which will need to be changed.

    Hi,

    I have recently had some new windows and doors installed. As part of the companies membership with FENSA, they have had a random inspection of their work by FENSA. FENSA have now stated that the internal door between the garage and kitchen is not a fire door and does not meet building regs.
    who is responsible for rectifying this and who should foot the bill.

    thanks 

    Sorry to say but that is a legal question, this is a fire safety forum that can not offer legal advice. I would however suggest, as FENSA raised the issue, you ask FENSA

  3. Are these mains operated smoke alarms with battery back up?

    Assuming that they are, there is no smoke alarm that is compatible with the bases that your alarms have. (BRK pulled out of the European market.) This means you will have to change the base and the alarm.

    All new smoke alarms should be interlinked (Check to see if yours were interlinked via a 3 core and earth cable) If they did have a 3 core AND earth cable then you can get any mains interlinked smoke alarm. If on the other hand they are NOT interlinked by cable you can get radio interlinked alarms that have a 10 year battery life and do not require an electrician.

    Safelincs supply a variety of smoke alarms which you can see if you Click here

  4. No green light means no mains.

    The fact that putting them on a different circuit and the green light comes on proves the devices are ok, and that the first 3 have no mains.

     

  5. If you installed wired smoke alarms in 2005 You should change ALL of them as they only have a 10 year life.

    If it is easy to install a new 3 core and earth cable from one detector to your new Heat alarm, then I would do that as it will be cheaper than all new radio alarms, but if it is not easy then yes, change them all to radio interlinked alarms.

  6. I would take it down, take the battery out, and hold the test button down for at least 20 seconds, then put the battery back and plug it back in again. You could also run a vacuum cleaner round it (To remove any internal dust build up)

    If this does not solve the issue then I can only suggest you buy a new smoke alarm (Another deta would make it easier to change and be compatible with your other one.)

    As for "someone coming out to look" it would cost you more than a new alarm and there are no serviceable parts.

     

  7. If you have turned off the mains, taken the battery out, your device is no longer powered so it can not make any noise. I can only suggest you check the area for something else that is making a noise. I have been called to situations such as you describe, only to find a device with a low battery on top of a cupboard.

  8. Take the detector down (You will have to turn the mains off first)

    Take the battery out

    Press and hold the test button for 20 seconds

    Put the detector back (Switch the mains back on)

    Put the battery back in (Or a new battery if the previous battery is close to being 12 months old)

    If that still does not work, you have no choice, you will have to replace the detector.
