This is a UK based forum, there are different regulations in America, so we can not help you at this time ?.

As you asked over a week ago (This forum has become very slow as of late) I presume the fire dept have been and gone? I would be concerned about the date on your CO detector, be it that is the installation date or the end of life date it needs changing. I assume you are in America? this is a UK forum.

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.

More information please: 1) Make and model of your smoke alarms is? 2) When you say Please be more specific, what happens, how often does this happen, how old are they?

Having never heard of either, I used google to find that the firex par 230c is made by Kidde, I then asked Kidde what the replacement is, they said "The KF20R is a direct replacement for the firex par 230c." So a big thanks to Kidde.

How is a megaflow a fire risk? As you say it is a pressurised cylinder full of water. There is no danger of it ever catching fire, and if there is an external fire the cylinder has multiple safety features.

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

It is not unusual for floor screed to activate carbon monoxide detectors.

If you have pressed the test button and the detector operated as it should, and the detector is within its expiry date then you have nothing to worry about.

There appears to be a problem with the electronics of the light fitting. It would be cheaper and quicker to replace the light fitting than to take it down and then to find someone to diagnose what component has failed (Capacitor) Safelincs can supply a new LED EM light for £25+vat Click here

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

Press and hold the test button for 30 seconds

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.

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.

Did you take it down, remove the battery then press and hold the test button? If yours is a Deta 1153 they are obsolete, and if the suggestion does not work, then you will have to change it.

Without being there to see it, it is hard to say, but I will guess you have blown a fuse.

Fridges do use a hydrofluorocarbon to keep them cool, if your fridge leaked it is possible that your CO alarm detected this.

Sorry, your question is?

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.

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.

I can only suggest you take it down, remove the battery, hold the test button in for 20 seconds, then reverse the process. I would also ask, how old is your deta 1153 ? as they are obsolete and it maybe near the end of its life.

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.

Most smoke detector manufacturers recommend the detectors be changed every 10 years.

Has it activated since? Oh, and not wishing to be pedantic, but CO2 (Carbon dioxide) is what makes fizzy drinks fizzy. (CO) Carbon monoxide is given off by unburnt fossil fuels.

If it is for yourself, it would be up to you to decide do you want to buy new cushions for it, if you are selling it, you could sell it without cushions. The cane furniture itself does not need a fire label, only upholstered furniture made after 1950 requires a label
