I think you need to clarify what is there. If the property has "domestic smoke alarms" these can not be "connected to the fire brigade" If the property has a "Fire alarm" Then this can be "connected to the fire brigade" However, I should point out that no alarm is connected directly to the fire brigade, instead it calls an Alarm Receiving Centre who will if appropriate call the fire brigade. In order to have this, the fire alarm must be up to the relevant standards and have a maintenance contract. Would it not be up to the new owners which insurance company they have and therefore up to the new insurance company what the fire alarm does or doesn't do.

It would depend on the company concerned as for what is and is not included in the service. You would have to ask them.

Does not sound like it is a smoke alarm, since it makes a noise every ten minutes. I would suggest being very quiet and listening for the noise and "follow it". Yes it is easy to say, but it can not be a smoke alarm with no power. I wonder is it an old mobile phone?

Following on from what Tom says, I should like to point out that although ideally an electrician should install the smoke alarms, not all electricians are Part P registered. So although any electrician can install them, not all electricians can issue a certificate that says the work complies with Part P.

Thinking out loud. Tom, what if the extinguishers in question are stored pressure. The engineer could not take anything apart, there for has no need to change the anti tampering tag.

It would depend on the clarity of the glass, the angle of the sun and any combustible materials near said float. Can you not move it if you are that worried.

If there is an electrical failure after the 3 hour test, and all the lights passed the test what will you do? The batteries need 24 hours to fully recharge, you can not really stay in a building for 24 hours watching .......... Ideally the test should be carried out at a time when the building will be empty for the next 24 hours.

Safelincs can supply you with smoke alarms, I would suggest the mains operated, interlinked with battery back up, made by Kidde Click here for more information. The kidde ones have the advantage that you can connect up to 24 units, so if you need to expand, you can. Also if you use Kidde Slick or Firex smoke alarms you can also use the Kidde hush button https://www.youtube.com/watch?v=OOlCMA2ZOQM

I honestly think that it is a typo. That would be some blind that is 200 m wide. But I have to agree with Tom regarding covering the fire exit. Think about it, if there is a fire, people panic, and will not see that there is a blind covering an exit, also the blind could get in peoples way. and if the fire exits are "to be used by children" how does everyone else get out?

Would it not be a good idea to actually look at the fire alarm panel first?

I would ask why would you want to do that? Emergency lights are to provide light when the main supply fails, a blue light is not going to be easy to see by.

Andrew, I notice you said Did you know that you are supposed to change smoke alarms every 10 years? Perhaps its time you changed yours? Safelincs can supply new ones Click here

I googled and found THIS

Just a thought. Why don't you ask the BCO to see what he wants? My reasoning is that if a reply said get sign "A" and the BCO said he wants sign "B" the BCO will not be happy and you will have wasted money on a sign the BCO does not want.

Only asking. What do YOU think is wrong with having ball catches and door closers on fire doors.

As Harry said, if you really want to test a smoke alarm use the spray he suggests, a match does not create enough smoke to activate a smoke alarm, and burning anything is very dangerous and also smelly. If you do use the spray, do follow the instructions.

I would say its vaguely possible for it to go off because of the heat, but more than likely because you put it above the woodburner. Put it back in the same place (for a short while) and see does it go off, if it does your woodburner is probably leaking CO

Fire extinguishers should be checked annually. Every 5 years, all but CO2 extinguishers should be discharged tested, checked and refilled, CO2 it is 10 years at which time it should also be stretch tested. I should also point out that as an extinguisher gets older, it will become more expensive to service and may be un-economical to do so, since a new extinguisher from safelincs CLICK HERE is cheaper.

There are a couple of problems with any type of adhesive fixing. 1) When you have to take the fixed item down, you find it is still stuck to the surface and will not move without damaging the surface to which it is fixed. 2) Any self adhesive tape etc will after time "dry out" and have no adhesion. I would suggest that you use "hollow wall" fixings, which you can get at any D.I.Y, store. I personally like these, Click here In your case, when its time to change the detectors you can undo the bolts (With a screwdriver) take the detector down, put the bolts through the new detector and tighten the bolts up, securing the new detector. No damage caused to anything.

All mains devices require an earth / earth termination point, UNLESS it is double insulated, which I doubt the smoke detectors are. It has to be there, but you don't use it, it is if some one should sever the cable, instead of the electricity flowing through the person who cut the cable, with possible lethal results, it flows to earth. (yes it will go bang, but its better that than to be............. Also as I first said, you should You do not know what damage may occur.

A second opinion is always a good idea. I would suggest you ask before you commit yourself "Are you familiar with mains interlinked smoke alarms" Although it may sound a bit condescending, I have found that some companies will say yes, but the bod who turns up at your place says otherwise. Emphasise the point you want some one who has worked on them before.

I would suggest that there being "no obvious connection in the fuse box" is because they are connected to a light / light circuit. This is considered a good idea, since if there is a problem with your smoke alarms you can not turn them off at the "fuse box" By connecting them to a lighting circuit you will not deliberately turn your lights off at "the fuse box" so the smoke alarms are always powered up. I would guess that if as you say the first two devices have a green light lit then as they are interlinked, the first place to check would be the 2nd of the two smoke alarms. _________________________________________________________ If it helps, Interlinked smoke alarms are wired as follows. Mains to first smoke alarm. Mains and interlink from first smoke alarm to second smoke alarm Mains and interlink from second smoke alarm to third smoke alarm (etc) The last smoke alarm only has the mains and interlink. So if a number of interlinked smoke alarms do not indicate they have mains, but some do indicate they have mains, the first place to check is the last smoke alarm that has mains. I personally have a "feeling" it is to do with the fact you have 2 different makes of smoke alarm.

On line surveys such as yours do not give good results, since you can "adjust" the way you look at the figures to give the results you want. I wish you luck with your project, but ask yourself this. At the end of the day, can you really make a better smoke detector that is affordable? If its not affordable it will be a "gimmick"

NEVER interlink mains smoke detectors that are from different makers. Change them ALL to the same make, even the the first two you already had. When a mains interlinked smoke alarm fails, you should only replace it with one from the same maker.

To add to what Tom said, if the fire brigade were called (and it was a genuine fire) who is to tell them that there are people still sitting in the building (not to mention the residents) it can't be you because you are still sitting in the building waiting for....... Yes, it can be a "pain" if you have to evacuate a building, but, is it not better to get out and find its a false alarm or would you rather stay inside and find out that one day its a real fire.
