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?

You only need to establish "Do the emergency lights come on in a power failure" (Which as you said is done by operating the EL test switch) you do not need to turn "normal" lights off plunging the place into potential darkness unnecessarily.

Make and model of smoke alarm please, and what do you mean by "She’s racing out there right now"

Your question is a legal one, this is a fire safety forum and as such does not offer legal advice.

Hi Sharon, Louisa asked the question way back in 2016 (It is now 2023) she has never been back since, so will never reply to you, I can only suggest you do as Tom suggested.

The threaded part of a CO2 fire extinguisher (as shown) is not replaceable. (It is under extremely high pressure around 55 bar) Safelincs can supply you with another CO2 extinguisher for around £30 Click Here

There are generally two types of emergency light. Maintained is an EM light that is illuminated at all times, and if there is a power failure it will stay illuminated as it has a battery back up that will last for a minimum of 3 hours. Non maintained are EM lights that only illuminate in the event of a power failure, and will last for a minimum of 3 hours I wonder are you thinking of self testing EM lights? Self testing EM lights "do as it says on the tin" they carry out all the required tests without help, they only have timer software, so that means they will carry out all required tests over 12 months but you can not determine when as they have no calender software. Self testing EM lights also have multiple coloured LEDs and a "beeper" and problems or potential problems are indicated by the sequence / colour of the LED's and beeper. The colours/flashes vary according to each manufacturer. In general, after installation and power up the software starts, 24 hours later the light will carry out a 3 hour duration test, after that it will change to a 30 second test (To establish if the light will illuminate on battery power) once a month, it will start the whole sequence from the beginning 12 months later, as said previously, if any problem is detected then a LED / beeper / sequence will initiate. As the lights are independent it would be wise to simply look at the indicator LED on each light once a month.

When is opening time?

I can't help but think that the person who asked the question has long gone since they asked in 2014, and the next person asked in 2020, then again in 2021. My point being this topic has been inactive for years, so pointless posting.

If you pressed the test button and nothing happened it means the unit is not working as it should, and as it has no user serviceable parts the whole thing should be changed A.S.A.P. either that or you did not press the button correctly.
