The sensor is a metal Chrome plate with fins its contain americium to trigger Red LED and sounder or buzzer (piezzo electric buzzer and is black plastic resonator) horn when it detect smoke and fire, the other i think black piece i think is a optical sensor but not sure any idea?
@@luiscoelho4151Yes; this type of alarm is both a photoelectric and ionization, containing both technologies, which the black part is photoelectric and the metal part is the ionization.
ArtisanTony smoke alarms use a radio active element (americium) and a receiver plate. When that plate doesn't get a radioactive signal from the americium, ie blocked by a particulate like smoke or dust it goes off.
Stewart Knight There are photoelectric smoke alarms which use an LED and an LDR. The smoke alarm in this video is a dual ionization and photoelectric one.
This model is a ionization and photoelectric; the metal part is the ionization, it is radioactive. The plastic Is the photoelectric. Which is a laser; and if the path is interrupted, it is triggered.
When he put the dust into the smoke alarm for the third time while I was looking at mine with headphones and when it went off in the video it startled me
*Sprinkles sawdust onto the piezo horn..... "I think we'll take it to the range and shoot it, see if that'll set it off" Genius hour at the brain trust. Truly.
The part you put the dust into was the horn. The sensors are the other two, as that is a combo alarm. It uses ionization and photoelectric, but the best result with the sawdust would be to put it into the ionization chamber which is the silver one.
The first black thing you put dust in was the thing that beeps really loud, not a sensor. I may be incorrect but I believe the thing with the slots around it was the actual sensor.
Christian Lifts N' More This smoke alarm is dual ionization and photoelectric. The black thing is the photoelectric sensor and the silver thing was the ionization sensor. The thing with the hole on top was the buzzer.
The one that you said is the sensor isn't actually is, it is the horn. The black piece right next to that horn which you said was the sensor is the photoelectric sensor which is better at detecting smoldering fires, and the silver piece next to the horn is the ionization sensor which is better at detecting flaming fires. Some detectors only have one of the above but some other, like yours, have both sensors in.
Im here because my fire alarms kept going off what seemed like none stop for like 3days and it was because of one falultly detector. Once we got a new on I took the faculty one outside and threw it on the ground millions of times
The 'dust' has to actually get into the sensor unit for the photo electric part to operate. It uses infra red light reflection off dust or other particles to activate the sensor. Take the top off the detector chamber and do it that way, not just pour stuff around the sensor head. The silver unit is an ionisation chamber. Try burning some toast around it and see what happens.
Thank you for making your point this is very true. The silver one is ionisation and the black left one is the photoelectric sensor. It will most likely be the ionisation that's making it go off
I build for a living and I leave the dust covers on smoke detectors until the new owner moves in. Sometimes I forget to take them off. In my house, we had two dust covers left on for over two years :) Thanks for watching :)
Colin Ota The silver thing is an ionization sensor. The black thing (not the horn in the middle) is a photoelectric sensor. The ionization one responds to flaming fires and the other one does to smoldering fires.
Could be but is one of them a carbon monoxide detector? Do you have gas appliances? Make sure of these types of things too just to be safe. But you can vacuum it out for the dust.
@@Luka-ty4qr it could be dust but just make sure you have no vent leaks on your gas equipment. As you know carbon monoxide is odorless so I would check into it. I have seen gas vents leak and also gas fireplaces set off carbon monoxide detectors.
HighVoltageMadness2300 that makes no sense. If it’s hard wired, there is no battery. My parents have hard wire one for 20+ years and have never changed them out. They still work and I do an annual test on them to make sure they still function.
@@ArtisanTony Clarify, that black object with a hole on the top is the piezo which makes the loud noise. However the black and silver pieces on the sides are both sensors.
@@ArtisanTony Some had a yellow cap on the sensor. That is why they were recalled. You should replace it with something else like a First Alert SA320CN which is also a dual sensor but there is still better ones like Nest Protect.
As someone who collects smoke alarms, I can confirm that this is beyond true. Every month or so I disconnect mine and use some compressed air
i love the soft calm music he was playing in the background. really nice
That the horn, not the sensor!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

MY SCHOOL FIRE ALARM WENT OFF DUE TO DUST
that's crazy :)

Some random alarm in the distance: 4:16
You guys rock 😅
awe thanks! so do you :)
The black cylinder with the hole in the top of the alarm is the horn that makes the sound

Dust? You put fucking SAWDUST in there!
2am for me. Lol
Some of the notes he was playing literally almost sound like creeds "one last breath" it had that vibe to it! But funny informative video! Lmao
Ha, thanks
My alarm made that sound just now so now I know to clear it of dust, Thankyou
The silver chamber is the sensor. The black part is the horn.

haha, they can be annoying as heck for sure. And the code requirement that they all be interconnected makes it worse :)
@@ArtisanTony OMG YOU REPLIED! I didn't expect that.

THe donut is a speaker
Justin Bellio that makes sense. The older ones had like a couple be speaker so it threw me off
The sensor is the silver piece

Both of them are sensors
Are you need to let it sit till four in the morning LOL
You can’t blame it for it doing it’s Job
All the smoke detectors in my house are going off early in the morning. Could it be because of dust?
Could be but is one of them a carbon monoxide detector? Do you have gas appliances? Make sure of these types of things too just to be safe. But you can vacuum it out for the dust.
@@ArtisanTony yes they are Carbon Monoxide as well
@@Luka-ty4qr it could be dust but just make sure you have no vent leaks on your gas equipment. As you know carbon monoxide is odorless so I would check into it. I have seen gas vents leak and also gas fireplaces set off carbon monoxide detectors.
Here we go again. You should use a fan
It is silver one in the black one is the speaker
We all know that now lol
12-year old hard wire smoke detectors in my house that pissed me off at night because they start chirping even though we just changed the battery.
HighVoltageMadness2300 that makes no sense. If it’s hard wired, there is no battery. My parents have hard wire one for 20+ years and have never changed them out. They still work and I do an annual test on them to make sure they still function.
Replace them if there over 10 years old...
@@mclaine33 bruh most hardwired alarms have battery backup in case of power outage. also @HighVoltageMadness2300 Replace those alarms now!
I say skeet shooting practice!!!!!!!! PULL!!!!! beep beep beep BANG!
jam jam's that is a very good idea :)
me too
You poured dust into the horn, not the sensor. The sensor is the silver thing.
read the comments
The black thing(not the horn) is also a sensor.
@@ArtisanTony Clarify, that black object with a hole on the top is the piezo which makes the loud noise. However the black and silver pieces on the sides are both sensors.
@@BukuiZhao Yes, thousands of people have told me lol
4:14
The alarm clearly doesn’t like you because it waited until there was no dust inside to go off
What he says is the sensor is the horn
lol, it has been said a million times by now lol
that not the sensor that the horn
Perhpas Smoke Alarms dont like real dust but they love saw dust.
Why don't you use real dust?
I dont think there is much saw dust in my bedroom
Dust is dust dude. It all comes from the Earth. You aren’t one of those flat earthers are you?
Try vapour
how poetic :)
Those were recalled
figures :)
@@ArtisanTony Some had a yellow cap on the sensor. That is why they were recalled. You should replace it with something else like a First Alert SA320CN which is also a dual sensor but there is still better ones like Nest Protect.
I had a detector go off because of a spider....
jrossi9250 hopefully it annoyed him :)
Was it wearing a fireman’s cap?
That's interesting
I think so too but Ima building geek :)
