2:47 is the best one.

nice collections

should have an ionisation and photoelectric smoke alarm in your home

I will always use a ion detector as it is a neat-o alpha radioactive. I'll get a photo one too.

Then why do they use them in schools.....

Get the Kidde PI9010

I need dual ionization and photoelectric detector

no radiation either

fadi butris Ionization is not bad to your health, the ionization alarms are bad to your health.

Smoke detectors with both Photo/Ion will save lives verses one type or another

Please can i have an answer to my question, i have a ionization frie alarm/smoke detector from 1999. If we don't think about the chance of dying in a fire, how dangerous from the radio active perspective is it to my health having a ionization fire alarm/smoke detector from 1999?
