No, Blackwood fire is a "Fire protection company" based in Wales, like most fire protection companies they buy things in, in quantity and have their own brand sticker put on it. It is only my guess that it is a roshni, your screen shot is of such a low resolution it's not possible to be 100% accurate, also as you say it is no longer there, so it can not be proven one way or the other.

That looks very much like a "Roshni" fire alarm sounder. A very common conventional sounder. It has a choice (via DIL switches) of 32 tones. It operates at 24v (But will work at 12v) Still available today new for less than £30

I would suggest you contact the boiler installer to establish why it beeps. I would also suggest you buy and install a carbon monoxide alarm, one with a digital display is best such as the kidde unit. Click here as it not only has a digital display it also has a peak level reading too.

Your alarm is 7 years old, the Deta 1151 smoke alarm is obsolete. I would suggest you change the complete alarm, also if you have any other Deta 1151 smoke alarms I suggest you change those too.

I would suggest you call a locksmith and get a new lock fitted.

Fire testing of furniture is a very rigorous and expensive procedure and often costs more than the single item being tested, so it would be cheaper to buy a new item of furniture and give that away. Also, after rigorous fire testing the item will be severely burnt (Due to how it will be tested) writing the item off. But if you are a private individual, there is nothing stopping you from selling it to another private individual, so long as you do not turn this into a business.

There are generally two types of Emergency Light. Maintained and Non Maintained. Maintained has a permanent mains supply, its light source is illuminated all the time. Non Maintained has a permanent mains supply but will only illuminate when the device has a power failure. Some non maintained Emergency lights can be configured as maintained. You may have purchased a Maintained light instead of non maintained light, or you may have configured it wrong.

There is no regulation that says that fire detection devices must be replaced after 10 years, and when tested so long as a device works as it should it still complies, however it is also recommended that the manufactures instructions should also be noted. In the case of your System sensor heat detector and your Honeywell smoke detector both state "They can not last forever, and we recommend replacement after 10 years" I have seen detectors that are over 10 years still work when tested. There is of course nothing to stop you paying to have them all changed any time you wish.

To silence all of your smoke alarms after ascertaining there is no fire you press the test button. This should silence all smoke alarms. After 10 minutes of the silence button being pressed the detectors will "reset" As for which smoke alarm initiated the alarm condition the manual is not specific, but I would suggest you look at each smoke alarm and see which one is flashing differently.

I would be asking who told you a CO2 extinguisher should have a gauge?

If such a device exists you would need to interface it to your existing fire alarm panel, this would NOT be a DIY option. Alternately, you can get smoke alarms that can (via an interface) signal your mobile phone.

Hello Cri, you have miss-understood. I never said the Aico smoke alarm baseplate is compatible with the Deta Brand. I said Other manufacturers change the design of their smoke alarm and change the design of the baseplate accordingly. Aico have changed their smoke alarm design (slightly) and brought out new alarms BUT they all use the same baseplate For clarification, I have attached a picture of an Aico baseplate and another brand of smoke alarm baseplate. When changing a smoke alarm that is interlinked with other alarms you should change all of them at the same time to the same brand as this avoids any compatibility problems and gives the assurance they will all sound when they need to. The other thing to consider is that most smoke alarms require an optional baseplate to be ordered, Aico alarms do not require this as it is included in the box and is part of the alarm. I should also point out that when mounted to their respective baseplate most smoke alarms are deeper than the Aico

If it is your own private house that you live in, it is up to you to install/have installed any more smoke alarms as you see fit. Ideally as you said each bedroom should have its own smoke alarm as well as each habitable room (Lounge, dining room, study etc) also as you said the kitchen should have a heat alarm. It is also a good idea to have a carbon monoxide alarm in any room that has a fuel burning appliance. Alarms should be interlinked

If you have changed 3 batteries in 3 smoke alarms and all 3 have their green light constantly on and the red light flashes every 40 seconds (as it should) There is nothing wrong with the mains supply, so to call an electrician would be pointless 😗 (Note: There are no user serviceable parts other than the battery) The symptoms you describe are not unusual, and it is a simple solution. There is another detector close by that does indeed have a low battery, it may be on top of a cupboard or in a drawer or even in the loft, I my self have been on jobs where the customer has asked me to look, and every time there has been another alarm found (Some are still in their packaging "thrown to one side, and been forgotten") also don't forget carbon monoxide alarms have batteries too (Mine started beeping last night) A case such as yours was posted May 2023 (Top of this page) I would also suggest you check the model as the Ei141 is an ionisation alarm and is obsolete. It would help if you post your findings.
