The old Fyrnectics (the one on the ceiling) went off because the smoke went into it, the other two stayed silent because the smoke didn't go into them. I mean except at the very end where you put the ashes of paper straight under the old Firex one (the old one on the wall), but I guess this one lost its sensitivity which doesn't surprise me due to its age. Also what's nice is that the 3 alarms you have all make a different sound: the one on the ceiling we can hear does this "beebeebeebeep", the new one on the wall would sound 3 long beeps then silence for a second then resume, and the old Firex on the wall would logically do an extremely loud, low pitched buzz that would make the wall rumble, so you immediately know which one is beeping
Doesn't surprise me that the old Fyrnetics went off first. I was fully expecting either that one or the older FireX. Newer smoke alarms tend to be not the best quality from my experience
I can relate. My house had two 30 year old hardwired fireXs when we moved in,(just like the one in this video) that STILL DETECTED SMOKE! Then we later replaced them with what I later learned crappy kidde ion detectors
@@supersonic5900 You probably got a Chinese knock off. They are doing that now and you have to do your homework. There is an internal attempt to destabilize what's left of capitalism to make people need welfare and crap so they'll keep the socialist governments with their fat paycheques in charge.
OK, I'm going to try to be nice because you could have started a fire right there and burned down the house, I didn't even see an extinguisher in the video. Secondly apparently no one seems how smoke alarms actually work. The old detectors on the ceiling are ionization detectors and react faster to fast flaming fires. The new detector on the wall was a photoelectric smoke which reacts faster to slow smoldering fires. Most home fires start as slow smoldering fires by the way. The sound on the new one is called temporal 3 and is required for all smoke alarms and fire alarms, has been for a while. Smoke alarms are mode much better now as they are building in false alarm resistance. Ion detectors contain radioactive material which depletes over time and may respond very fast to certain types of fire but not to others. My suggestion is to buy a combo one that has both technologies in it, but trust me if you have only one type it is the photoelectric one you want. I am a fire alarm tech for 26 years now and photos have been our industry standard for 30 years, that should tell you something. Ion detectors are installed by default in a home because the cost is half that of a photo. Certain states have even banned ions in new construction. I know your test seems like ion was better but watch the UL smoke alarm test video, that simulates a real home fire.
Thanks for sharing all this knowledge that you have accumulated over your career. I did indeed have numerous fire extinguishers on hand as well as other methods of extinguishing flames. What specific models of smoke detectors do you recommend for residential applications?
Out of what i know is i do own a fully functional Fyrnetics 0905 (that sensitive one in the video) and they work great! Back in the day smoke alarms were better made Sensors than nowdays. Yes keep them up and running
lets see here: the fyrenetics was right above the flame and only went off when paper caught fire, producing invisible fire particles, the fx1218 was behind the open flame, and the first alert was probably using a photoelectric sensor
A can of smoke detector tester is commercially available. I'd recommend that as opposed to setting paper on fire in your house. A flying ember could've easily started a real fire.
There are testing products for smoke detectors, smoke in a can, matches designed to produce enough smoke to trigger the detector but the best option is to replace the unit. Lately they have become commonly available with 10 year lithium batteries which is a logical choice
@tubby's alarms, reviews, and more I have one and the first was totally defective - lasted 3 months before falsing constantly, the existing one is 4 years old, doubt it will make it to 10. I don't know what the heck kidde did in the design to make them so crappy. their 10 year backup strobe/monoxide units are also really bad and that type is mandated for new construction in my province. manufacturers probably did some lobbying.
@@K1tty-cat sadly in the country where i live smoke detectors are now generally either mains powered (with battery backup), or the type with a sealed battery, and after the recent change in the law in Scotland, i think detectors with a 9V battery may disappear completely from where i live, i do not live in Scotland, but i do live near the border (since you likely won’t be familiar with the new laws in Scotland, essentially the new laws require all hallways and all landings on all floors to have a smoke detector, the main room in the house (usually the living room) to have a smoke detector, and there to be a heat detector in the kitchen, all detectors must be either mains powered or have a sealed 10 year battery, and all detectors must be linked, so if one goes off, they all go off)
