Assuming your carbon monoxide alarm has only gone off just the once, and it is NOT near its expiry date (Check the unit itself for a date, the average expected life is 5, 7 or 10 years, depending on make/model) and it still works when you press its test button, then you have nothing to worry about.

Just saying........That is a unican mechanical door lock by simplex, it will stay locked until opened. (Unless it is "put on the latch")

"Chirping" (once every 60 seconds) is a sign that its back up battery is flat. Although it is a new smoke alarm I would still suggest you change its battery

Without seeing it, it is not possible to say, but my guess would be that it was a mains powered smoke alarm, and now it is a battery operated smoke alarm, the downside is if the smoke alarms were interlinked (So that when one goes off, they all go off) they will not now be interlinked.

Stand-alone battery operated call points were designed to be used on building sites, if it is a very small premises you could use one, but equally you could raise the alarm verbally. Stand-alone alarms can be linked to each other if they are the same brand, but not linked to an existing hard wired fire alarm as they are not compatible. What does the fire risk assessment say?

Put the alarm back in the room from where it came and leave it for a while, if it does not go off, press its test button to ensure it is working. If it only goes off when you press the test button you have nothing to worry about. If your carbon monoxide alarm does go off again something is giving off carbon monoxide and you will have to investigate further. Carbon monoxide is colourless and odorless so you can not see or smell it, and it is not un common for carbon monoxide alarms to go off when concrete screed has recently been laid.

I presume you mean green light? If the light does not stay on when the mains is removed (You said it is a maintained light) that means the batteries are no longer holding their charge and should be changed. Safelincs can supply replacement batteries Click here That said if the light has a fluorescent tube you may want to consider changing it to LED as there is not that much differance in price Click here

I googled, and as far as I can find they are no longer installed, instead locks that the fire brigade may need access to use one of 6 keys, the set is called a "fire Brigade set" "Set of six Fire Brigade keys. Used by emergency services, councils and other authorised bodies. Comprising FB1, FB2 & FB4 for mortice deadlock and rim lock keys and FB1/FB5, FB11 & FB14 pipe keys for Fire Brigade padlocks."

Just because the materials look identical does not mean that they are identical (It would not be worth while taking it any further) as they do not have the required UK fire label as you have found no charity shop will accept them*. However as you are private individuals, there is no law that says you can not give (or sell) them to any Joe Bloggs. So there is nothing to stop you advertising them on the likes of Gumtree. If you have no joy with gumtree you will have to pay have them taken to the local tip, try gumtree first as collection only. * If it helps, British people have the same problem, no fire label, no charity shop will take them.

The recommended replacement for the Ei150 smoke alarm can be found if you Click Here The base will have to be changed (It has no plug, as the connections are made to the base plate)

That depends on make and model of emergency light, most only have a single green LED, not a red and green LED

Fast flashing red light indicates the unit has gone into alarm. If it has not cleared press and hold the test button for at least 10 seconds

Maglocks are Extra Low voltage (12/24v) So they are usually powered from a power supply (Usually a large white box) I would suggest you find it and make sure it has mains going to it, (Usually a small green light) the other possibility is that it has batteries and these have gone flat and are dragging the power supply down There is also the vague possibility someone has pressed one or all of the green manual override points

Hi, "Doreen" has only made the one post so you are unlikely to get a reply from her, but if you read her post again, it does answer your question That said, even the replacement is now obsolete. You will have to buy a different brand of smoke detector, the downside to this is that as yet no two different brands of smoke detector will work with each other, so that means you will have to change all of them at the same time. Looking on the bright side all non radio interlinked smoke alarms use a 3 core and earth cable, this means no rewiring to do, but you will need to change each smoke alarms plug.

Most forums have a pixel size limit, most modern phones / cameras take pictures that are too big. You may have to use an online picture re sizer.

Why would it be a breach of health and safety? In some cases when the fire alarm is reset the AOV's will close, if this is not the case (Quite often it isn't) Then who ever resets the fire alarm should close them.

Mains smoke alarms are wired in parallel, and are "independent" The only common thing they have is alarm indication, so the green "power on" light on one device will NOT affect the others. If all devices have no green light I would suspect a supply problem. If one does have a green light and the others do not I would suspect a wiring error. You can of course swap them all (On a just to find out basis) with the one with the green light to see do they work.

You do not need a fire safety label if you are getting a new sofa. You only need a fire safety label if you are selling your old sofa and you are a business.

You would have to ask the manufacturer, but in all honesty, I doubt it.

No, you have nothing to worry about.

I can confirm that a modern LED emergency light draws just over 1 watt. (As shown in the picture below)

Maybe it is to direct the light to where it is required. Have you an example picture?

What do the units instructions say? Does it have a built in thermometer ? (You do not give the model number)

It is quite common for a carbon monoxide alarm to activate after a new screed floor has been laid, this forum has quite a few such instances.

You can get wireless interlinked smoke alarms. They can either be battery powered or mains powered. You can get them from Safelincs Click here
