green-foam

In short it is good advice, but the electrician is wrong in what he said and probably saying so to get extra work.

The green LED indicates that mains is present, the red flashing LED should flash once every 40 seconds to indicate it is working. Deta give their smoke alarms a 5 year guarantee. So I can only suggest you get in contact with them.

If the fire alarm is addressable then it may be possible to add an I/O interface. But it would be a job for the fire alarm company to do. It also depends on the make of fire alarm as to if it will accept an I/O device.

Which alarm was it? Make / model, how old is it, when did you last change its batteries?

You do not say make / model of your CO alarm, but generally beeping every 30 -90 seconds means time for a new battery. Some CO alarms (and the one I had) only last 5 years. When did you last change its battery?

If you get the answer you seek, then what? The surveyor is clearly on the side of caution (But it may be the foam is flammable) I would also ask, since some of the tiles have hairline cracks how much would a new roof with under felt cost and how much would dry ice blasting cost?

Without knowing who made it / its specifications it is not possible to tell remotely anything about it.

Thanks for that Bif, it will do for reference, but no one has asked before and I should guess carlos has since found the answer, as he asked back in April 2020 ?

If it has now stopped bleeping, and still works when you press the test button, you have had a false alarm.

Smoke alarms (That you have in your home) are NOT suitable for use in commercial premises. You will need to get a Fire Risk Assessment carried out.

I see you have been answered on "my builder" 8 days ago (This forum is getting very slow lately) ?

Does this risk assessor provide your insurance? No? Check with your insurance company what is and is not permitted. I can tell you there is no such thing as a commercial grade extension lead for permanent use. Extension leads are designed for temporary use. There are a few guidelines when it comes to using extension leads. The cable should be suitably sized for the current it is to carry. (In other words, not too thin) If it is reel mounted it should be fully unwound when using a high load (Anything with a heating element, kettle, hairdryer, electric heater) if you don't the cable will overheat and cause a fire. (It's a very common problem with extension leads) Never plug an extension lead into another extension lead. Never run an extension lead under a carpet (It will wear out, short circuit and cause a fire) Never use an extension lead near water, and don't leave one outside. Ideally you should move what ever you have plugged in closer to the socket (So no extension lead required) or have extra sockets installed by an electrician. Extension leads make excellent trip hazards too.

Sorry, but there have been long delays with this forum recently. Yes. But you should still carry out a test as per manufacturer's instructions to establish does the device still work.

You need legal advice which this forum does not offer.

And your question is? As an aside most standalone carbon monoxide detectors have a working life of 5-7 years (I changed mine in 2020)

You appear to be saying your smoke alarm is only 6 months old, if this is the case, I suggest you send it back under warrantee. If your smoke alarm is over 12 months old I would suggest that as the BRK 670MBX is an ionisation smoke alarm I would suggest you change it to an optical smoke alarm such as This one from safelincs

Not ignoring you, this forum has got very slow lately.? MY OPINION Domestic: Would you pay someone to come into your house once a week to press the test button on your smoke alarm? You would also have to find enough people to let you do it to make it viable. Domestic is a non starter. Commercial: Similar to domestic, but with a twist. To comply with regulations it must be tested by a competent person, are you competent? Unlike domestic premises, there are commercial premises that do have an outside company test the fire alarm every week on the same day, but I would point out those that have it done, already have a company doing it. Problems: You would need your own: Transport, test equipment, insurances, paperwork to prove you have visited site, knowledge of a variety of fire alarms, (What will you do when you find one device that does not work?) cover for when you are not available, credibility, invoicing procedure etc. Solution: Go and work for a fire alarm company, such a job as you seek does exist.

It depends if they are interlinked or not. (You do not say) Also it depends on how long it sounded for, as interlinked alarms do have a slight delay. What happened when you pressed the test button.

It must have been a pocket of carbon monoxide floating about that caused on then the other to activate. Since you do not mention any more activations, I would have to assume the pocket of carbon monoxide has since dispersed. Have you since pressed its test button, and did it sound? I would however suggest you purchase a battery operated stand alone CO alarm that has a digital counter as well as the two you have and monitor the display.

The LED must be visible at all times, how else would anyone know the EL fitting is being charged. The fact is that companies that make EL fittings are just using brighter LED's for everything, there is at least one manufacturer who has added a "dimmer" to the green charging LED, hopefully it will catch on.

In the absence of a reply, I will explain my reasoning. A lot of folk will plug their toothbrush charger into the shaver socket and leave it and seem to assume "The plug fits, so it must be ok" This is actually NOT always true. The first shaver sockets were just for electric shavers and will only be used once a day for 5 minutes at most. (When the shaver socket was invented, there was no such thing as an electric toothbrush.) Unlike a shaver that is on for 5 minutes at most, a tooth brush takes close to 24 hours to fully charge, a tooth brush uses more current and is on for a considerably longer time than a shaver, this in turn causes the shaver socket to get hot, eventually the shaver socket will fail if it doesn't catch fire first. To combat this the shaver/toothbrush socket was invented, this socket can easily cope with the current demand and duration that a toothbrush puts on it, so to differentiate between shaver only and shaver/toothbrush socket a logo of an electric toothbrush has been added to sockets that can charge a toothbrush or a shaver. (See Symbol 2) the downside is most folk either do not look for "Symbol 2" or as I first said assume that if the plug fits it must be OK

Since it started to beep, which indicates a low battery, and it stopped beeping when you put in another battery, but then some hours later started beeping again, I would suggest the "new" battery you used is not suitable and that you should use as the manufacturer says, Duracell or Energiser.

What do you mean by "indicator emergency light?"

I would have to ask which symbol does it have on it, symbol-1 or symbol-2 ?
