Have you tried resetting the call point?

If you are confident to do so, then yes. But bear in mind, in an ideal world smoke alarms should be connected to the lighting circuit, not on their own MCB, also you will need a means of proving that the cables are indeed dead. That said, you might even find the reason why the existing smoke alarms do not work, I still suspect a broken neutral. An EICR is only to check the condition of the existing wiring, if the wiring does nothing, there is no need to check it any further.

If you really wanted to, then yes you can, but you would either have to install them in new positions or pay for someone to disconnect the cables for the existing smoke alarms, since you wont want them to cause problems in the future. I would guess the electrician who said the smoke alarms were live is not familiar with the operation of interlinked smoke alarms and only checked to see if he could find 240v. I would suspect a broken neutral wire, which would be cheaper to trace than buying all new detectors. Personally I would want to know why there is no supply, even if I was going to change all the smoke alarms

To have 5 smoke alarms have no mains indicator light showing does not sound correct. (I would suspect a wiring problem) With no mains the detectors will run on battery power, but when the battery starts to run low, the detectors will beep every 60 seconds, which is what you appear to be having. I should also point out that the Ei161rc is obsolete. But I would still get each base checked for mains voltage.

Self testing emergency lights are very reliable, they do not (as yet) have a way to remotely monitor their actions. If you do not "trust" them to self test, then I would suggest you replace them with conventional emergency lights, as if you constantly remove / reinstate the supply there is the vague possibility that you will "upset" the internal processor which is what runs all testing functions.

Does the property have working smoke alarms on each level ? The "problem" with fire extinguishers is that even though they have printed usage instructions on them, in a panic most folk will not be able to effectively use a fire extinguisher, also unless you buy "service free" extinguishers you will need to have them serviced annually, there is also the problem of malicious use. If you still want to buy a fire extinguisher for your holiday let I would suggest you get maintenance free watermist extinguishers as it covers multiple "risks" Two would be a good idea, as then there will be one for "spare" The other question is, does your insurance company require you to have fire extinguishers in your holiday let? Safelincs can supply you with water mist extinguishers, please Click Here What fire extinguishers do you have in your home?

Aico smoke alarms disable the battery when the smoke alarm itself is removed from the base. Doing this means the smoke alarm is non functional

Hi, the aico Ei141RC is an ionisation smoke alarm and is obsolete, I would suggest that the "symptoms" you mention are an indication of end of useful life. The direct replacement is the Aico Ei146e Click me

I have to ask, what country are you in?

For future reference I should point out that CO2 is carbon dioxide, it is what gives certain drinks their fizz, it is also what you find in these. Carbon monoxide is written as CO I would agree with you that running an internal combustion engine within a confined space was not a good idea and was the cause of the alarm condition. Since the alarm has not sounded since, but did sound when you pressed the test button, I would say there is no more CO present.

Hello RyanS, the post you replied to (Neil T) was posted in 2020 (3 years ago) and he has never been back since, so will never reply to you. I have a few questions for you. (I have to ask, as I am not there, you are) 1) Make of each smoke alarm 2) Model of each smoke alarm 3) Age of each smoke alarm 4) When you connected them on site, how many "went off" 5) You said "They took 2 of the hardwired alarms down" to say that implies there are more smoke alarms, how many smoke alarms are there in total? 6) When you tried them at home, did you connect them to the mains and interlink them? 7) Did you press the test button when you were at home. (What happened) 8 ) When on site, when did they "go off" (e.g. soon as you connected one, as soon as you connected a 2nd one, after a few seconds, after a minute......)

If your mains interlinked smoke alarm needs to be replaced and there is nothing compatible, then you should change all of your interlinked smoke alarms to insure compatibility. It is your choice which brand you change to, Aico have a very good reputation, also they have a fixed base plate, instead of a dangling plug.

The green LED on emergency lights does (usually) indicate the battery is being charged and as such should be on at all times, unless there is a power failure. There are a few other possibilities: 1) Some "smart" emergency lights have self testing modes in which case it may be in this mode. (Most will flash the green LED) 2) Incorrectly wired supply 3) EL itself has a problem Make and model of EL would help. As would testing said EL

Not all green lights are the charge indicator, it could be an actual emergency light. You can get a "green LED" that is infact an emergency light, in the event of a power cut it changes from green to brilliant white, I have posted pictures of one before, here on this forum. Also I would suggest that the general association of a blue light is that of the emergency services, so would anyone want to cause more problems by having a blue light instead of green, I think not.

Several questions: Does it have any writing on it? What country is this? Why do you want to know? It may be a sounder, it may be an air freshener (seen that before) Please take a clearer in focus picture, or more

Several points to note: Turning any smoke alarm off is never a good idea as if there is a fire, you would never know. However, the alarm you show is an Aico smoke alarm with integral lithium battery, so it will continue to operate for 72 hours, (so pointless switching it off) upon power restoration the battery will be recharged. Smoke alarms should not be mounted close to an edge, such as you show. This is because moving air (convection) can bring fine particles into the smoke detection chamber, causing a false alarm. Smoke alarms should be mounted at least 30cm away from all obstructions where ever possible, if not it should be mounted equidistant. Aico smoke alarms have a 5-year guarantee, but I suggest you change the position of this one first. 🙂

Have you wired it right? Have you installed the EOL capacitor, have you the correct KAC MCP? Have you swapped its position with an existing MCP? I can't be more specific as you gave so little information.

Make, model, age of alarm, time (Day or night) it beeped, when did you last clean it? Please.

Domestic smoke alarms are just that, for use in domestic premises, not commercial. What does the fire risk assessment say?

The person who initially asked, did so over a year ago and has never been back, if you have changed the device and you still have problems, I suggest you look at the devices "either side" to make sure they are not wet or corroded. You could also try looking for on line technical support from advanced.

Hi, as the question was asked way back in 2022, and the OP has never been back since, could you please be more specific. What make/model are the detectors you have, how old are they, when did you last change the batteries, have you cleaned them, what is the problem you are having, how often does it happen?

I can't say I have heard of fire doors in a caravan I would also say I think interlinked smoke alarms would be a bit too much, it is after all only a caravan. Sorry to point out the obvious but the original poster, said in the first line, they are asking about a caravan I guess that bit got missed

I would suggest for the definitive answer, you get back in touch with the company/person that made the report and ask them.

The green light indicates there is mains present. The red LED should flash once every 30-40 seconds to indicate all is well. The red LED will flash once every 8-10 seconds if the alarm has been silenced The red LED will flash once a second (and the sounder will be operating) if the unit is in alarm condition. What happens if you press the test button?

As I have said before. Hi charge usually means the battery is being over charged. What do the instructions say?
