Following the taping of this video I had an influx of purchases from my eBay page, so there's only one item listed for sale right now, but I have lots of other things waiting to be listed as I get the time to do so.
4:52 The actor doing the two TV commercials is (was) William Conrad. And like another commentor, my smoke/heat detectors are Ademco, tied to the ADT alarm; they can wake the dead 😆
"The story I heard" is that when cheaper consumer level smoke alarms starting being sold, it was facilitated by the need to get rid of the tiny amount of Nuclear material in them, ("Americinium"?) which had to be disposed of due to the reduction in nuclear weapons due to Peace Treaties. Maybe folks weren't buying enough of them as various jurisdictions around the world have recently made more smoke alarms compulsory. Maybe it's just a story...
Americium-241 has never been used in weapons. The earliest ionization smoke alarms used Radium, but Americium was found to be more efficient, emitting more alpha particles and less harmful gamma radiation. Ionization is only one type of smoke alarm, anyway. The superior photoelectric type uses no radioactive material.
@@themaritimegirl Don't these also have a heater? I remember if these gone bad, it didn't go off anymore. But it's a long time ago since I had these. We now have these light chamber detectors here in Europe.

One of the smoke detectors in my house is a 1990's Ademco smoke and heat detector
They missed the following features: "Gives early warning of the toast being done.", "Can function as a cooking timer"

americium though is produced in nuclear reactors@@themaritimegirl
The ionization chamber is expired.
If this smoke alarm was 400 years old, you would be correct.
And if that were the case, it would be false alarming, not refusing to alarm altogether.

no heater - only radioactive source. @@kyoudaiken
