Iíve been reading the Fla building code.

Re: Smoke detector drive me crazy


Around here the new code call for models with the 10 year lithium batteries. These will be nice to have and avoid the routine battery replacements.... especially if you have one like mine that is ridiculously high on a stairwell ceiling. Always an adventure up there to change a battery or detector.

These units, at least the ones made for kidde are complete garbage.

I've experienced first hand - defective and constantly going off.

The reviews are horrible - many are defective and have false alarms and batteries dying prematurely.

The concept is bad - ordinary alarms can work just fine beyond 10 years, they just need to be tested regularly. With the sealed lithium unit, you're forced to throw it away after 10 years.

I'm betting the manufacturers lobbied for requiring a non-replaceable battery to create an ongoing market.

Re: Smoke detector drive me crazy


It is a requirement in most jurisdictions that any and all smoke alarms be replaced after 10 years.

Re: Smoke detector drive me crazy


As long as it's not enforced, who cares?

Corporations lobby for laws - in the worst case they practically write building codes to ensure use of their products.

Re: Smoke detector drive me crazy


Many years ago, I learned that ionization detectors were more sensitive to ambient conditions and would alarm when nothing was burning. This would occur when there was a rapid change in humidity. I seen this happen at a hospital when someone would open a door to the laundry room. The hospital switched over to photoelectric detectors and the false alarms stopped.
Now whether this holds true today, I do not know.
However Manufacturers have had plenty of time to correct the faults of both types. There is a differance on how both operate. A photoelectric smoke detector will alarm when there is visable smoke whereas a ioniztion detector will alarm when it detects the invisable products of combustion called ions.
Here's what I would do to correct the problem.
1. Identify all detectors as to type.
2. Make sure the detectors are not a dual type that also detects carbon monoxide. Your better off having carbon monoxide detectors as a separate alarm.
3.Take more pictures of your detectors and list distances to any source of combustion. Especially the one thats above the ac intake.
4 All your detectors should be of the same manufacturer.
5. Part numbers should be the same on all photoelectrics.
6. Part numbers should be the same on all ionization detectors.
Email the manufacturer with your pictures and explain the problem.
My initial guess that you have ionization detectors in areas where
they should not be.

Re: Smoke detector drive me crazy


ionization alarms still have all the same flaws they did back when they were new technology.

used alone without photo electric, they provide a false sense of security since smoldering fires don't produce enough invisible products of combustion in the smoke to be detected until it's too late.

they're still made only because they're cheap to produce.

Re: Smoke detector drive me crazy


just a throw in from me,

we had an electric stove and we never had any problems, went gas and then the alarm went off regardless, we changed the extractor to a more powerful one no joy, then changed the smoke detectors out.

can't rmember which way round, ionizer to PE or vice versa, that did the trick,
now if the alarm goes off, theres a reason behind it ! LOL

HTH

Re: Smoke detector drive me crazy


I learned something when working. Donít spray anything on smoke detectors. Had a fly in my office. Tried spraying with bug spray. It flew out into the hall with me following. It landed on a ceiling Smoke Detector and I sprayed it and immediately a red light came on and I thought Ďoh crapí. Yes a big fire truck came but I met them out in the drive and explained. I know they snickered.

So these detectors are hooked up to some type of alarm that calls the fire department?

For many years, hospital nurses would put blankets in the microwave to warm them. Until one day the blanket started to smoke, set off a smoke alarm & a Fire Truck came, big fine, That might have been the advent of blanket warmers.

Re: Smoke detector drive me crazy


Nik, those heated blankets are absolutely wonderful. I’ve thrown an afghan in the dryer when I’ve gotten chilled.

I’m looking online for photoelectric SD. Most have the 10 yr battery.

In my garage I have a radioactive old SD laying around that said replace after 10 yrs so when I bought this house I took it down. But the Hazardous Waste place is out of the way an I never bothered to take it there. Yet.

Thanks everyone. I never would have known the difference in ‘I or P’ without your help.
