Why not get a fire alarm company to quote the job? Fike are often installed by electricians because they function, easy to install and inexpensive, but they are not ............"the brightest button in the box"

Its down to what the manufacturer says in their guidelines. The life expectancy of a sealed lead acid battery varies between 3 and 5 years (Depending on brand) Batteries should be tested at least once a year. If they fail the test they should be changed, but to fail every year ? A lot of companies use a specialist battery discharge test meter. This meter gives a reading of the "approximate remaining capacity" of the battery under test. You could ask them do they use this meter and if so can you see the results yourself. (It is not uncommon to log the results of each battery test, so that you can see over time (years) the resulting figure getting lower and lower. The battery should be changed before it gets below the limit set for that battery capacity) Also it is a good idea to write on the battery its installation date with an indelible pen.

To add to what Harry has mentioned, I was recently speaking to someone who said they had a "beeping noise" from a part of their house, and they took the smoke detector down and took the battery out (I know, bad idea, since they will never put it back) but they still heard the beeping, after more searching they found that another smoke detector had been installed in the "electric cupboard" and it was this that had a low battery. My point being always be 100% sure the "beeping" is coming from the detector you suspect, and that there are no others in proximity of it.

I have only just seen your post, I looked up the manual on line and it says it uses 680 ohm resistors, but if you are extending a loop you should also move the EOL device to the new EOL position.

I have to ask, have you changed the battery in the ei141 too?

I have to ask, Udo, where are you / where is this laser cutter?

It would be up to the insurance company what they require (if anything) It is not law that you have to have smoke alarms in an unaltered house (But it is a very good idea that you do) A house that has had just a rewire does not have to have smoke alarms fitted, but as said previously it is a good idea. Smoke alarms have to be installed under building regulations if the house has had another another level installed, a loft conversion to a habitable area or any new habitable area above ground level.

As the clocks have just changed, why not change the battery in your smoke alarm now...........or you could wait until it starts to beep at an annoying time of the morning. Even some mains operated smoke alarms have a back up battery that will also need changing. Safelincs do supply batteries for smoke alarms Click here If you have an an Ei xxx smoke alarm or a Kidde mains smoke alarm and you are not sure how to change the battery, you can see the videos of how to change the battery if you Click here

Thanks for that Bill. People often say it IS the smoke detector or its base when it clearly has no batteries or power............ And for the record (sorry to be pedantic) its CO not CO2 CO is carbon monoxide and is lethal in tiny amounts. CO2 is carbon dioxide which is what makes fizzy drinks fizzy

Sorry if i appear to be pedantic, but first of all its CO, not CO2. CO is carbon monoxide, that is lethal. CO2 is carbon dioxide, it is what makes fizzy drinks fizzy.* I would say that your detector has a low battery. Even though it is mains operated some do have battery back up which will require changing as and when. You will need to read the instruction manual for your particular detector (Sorry but you did not say make or model) (*Carbon dioxide in very large quantities in a confined space is also not good for you.)

Could have been, but i doubt it, more probable is that the detector actually detected carbon monoxide. You didn't leave the windows open / ajar did you? Operate the detectors test button, if it works as described in its test manual, and does not indicate carbon monoxide again, then you have nothing to worry about.

It depends on the brand of the battery and its age. Some brands will last around 5 years some only 3 years. But which ever brand of battery you have they should be tested. If they pass the test there is no need to change them, however if they pass the test but are close to the end of their expected life it would be a good idea to change them. Obviously if they fail the test / show signs of corrosion / other defect they should be changed immediately.

Hi, could you clarify your question as you have said you have to have either CO2 or foam in place of CO2 or foam which is what you already appear to have. Dry powder is often no longer used in "confined spaces / indoors" as it reduces viability. It is often replaced by foam.

I would suggest that if your fire wardens record the fact that CO2 extinguishers have "missing" pressure gauges, you need new fire wardens. If they are getting it worng about this, what else are they getting wrong?

For the definitive answer may I suggest you ask Fike's technical dept. You can contact them at fstsupport@fike.com The general phone number is 01633 865 558

I would say Melissa is in America, so knowing the make / model will be of little use to us here in the UK. However, I would say that if any CO alarm indicates CO, it is easy to check, take the alarm outside into the open air, and wait for it to stop, then take the alarm back inside, if it starts again there is a high probabilty of CO being present

There is such a thing as a "remote hush button" https://www.youtube.com/watch?v=OOlCMA2ZOQM However, it only works in "alarm conditions" it will not silence a "low battery" alarm. I would however suggest that you ask your son to change the batteries in all the detectors every 11 months, that way they are changed a month before they go "low battery" at a silly hour of the day.

It would depend on what the doors are for and what your access control system does, you do not say.

It will be an electro magnet. You just need to remove either of the wires from it and isolate said wire. Another easier option would be to remove the "Device" that the electromagnet holds onto.

And your question is? and you are what? in relation to the fire alarm

Either they will or they won't, so chances are 50 / 50

I would suggest you do not mark the floor, since some one could put boxes or similar around the markings, so that they have complied with your "keep the painted box clear" rule but still block the route to the fire exit.

Are you sure you are not meaning the battery in the fire alarm panel? Fire alarm panels should work for 20+ years, if well maintained. (I have seen panels that are older than this still working) But the batteries in the fire alarm panels should be changed as and when required which is usually a 5 year maximum.
