- Each type of smoke detector has its own unique properties. Did you know there are two types? Want to support the channel? then please buy us a coffee www.buymeacoffee.com/Q9Pj8HRcM

I like how fair this test is because the detectors are the same brand and series.
Everything you say in the video is true. But you are leaving out some facts. Ionization alarms are much more prone to false alarms, especially from cooking, than photoelectric. After experiencing multiple false alarms, people often unplug the smoke alarms to keep them from annoying them. Then, in a real fire, without a working alarm - you die. These same people, if they get photoelectric alarms would get far fewer false alarms, and therefore would not disable the alarms, and then in a real fire they would function properly and they would not die. In summary - get a photoelectric alarm and you are less likely to die in a fire.
In the UK (where I am) photo electric smoke alarms are more widely used than ionisation. Also you left out (as you put it) the fact that when the battery goes low, the detector will "chirp" I find THIS is the most common reason for people to disable smoke alarms. Even mains operated have battery back up that will chirp when it (The battery) gets too low.
Energizer makes a lithium battery in both 9v and AA that can be used in most smoke alarms instead of using alkaline batteries. This way the battery may last the life of the alarm and never need to be replaced until you replace the entire alarm after 10 years. Perhaps this is the best solution to the "chirp" issue that you say may lead to disabled alarms?
You are not wrong, energiser do make a lithium battery, but I feel I should point out that folk would only put an expensive battery in when the "free one" (that came with the detector) runs low, then they will just take the detector down..................
Although a lithium battery will last longer, it may not last 10 years in all detectors and so will start beeping so the detector will be taken down......
Yes, I agree with a flame detector, you buy me one and I will test it.
@flamesecureUK Thanks, but what is a CO2 detector?
Ionization alarms are for flaming 🔥 and photoelectric detect slow smoldering fires but you need both
Gonna say this, you got it backwards.
***** thank you, I know my detectors
What models are thoes smoke detectors I want to buy one, are the connected to a panel?
They are Apollo detectors. you can get them off eBay and conventional detectors [ones without buttons on the back of the detector] can be operated on batteries.
You said "You missed heat and rate rise" To that I would say
READ THE TITLE AGAIN! it clearly says "Smoke detector types"
Fixed and rate of rise are HEAT detectors.
It seems that the ion was faster at detecting the oil, and it was alarmed at the same time as the optical at the begining. You sure optical is better?
Ion is also much more prone to false alarm, not to mention
Where can I buy one ? And can you not get alarms that make the same noise but are mains or battery operated ?
These are mains operated I think, the Roshni sounders sound similar to these but I think those are powered by the mains too
You think wrong. They are connected to a 24v fire alarm panel, not mains
@@bluecylinder they mean, are they battery backup or powered by the mains?
Save your money, watch my videos. The detectors are for a proper Fire Alarm, they are connected to a proper Fire Alarm Panel, they do not work on their own.
Watch my other videos and you can see the panels etc.
Did anyone notice that for the first test the optical and ionisation both activated at the same time
Optical activated a few seconds before
No it didn’t the Optical one went off first, then a few seconds later the ion did (it was reversed in the next test)
The ion one, is better for kitchens
Well heat is the best for kitchens
Why didn’t the Optical alarm activate on the Oil Test? Only the Ion one went off
Edit: I was expecting the Ion one to go off, and then set off the optical one
External sounder.
How is there sound on the detector
There is no sound at the detector
You don't. You connect the smoke detector to the fire alarm panel.
Depending on the panel depends how you connect the detector, but most are strait forward. Join the forum then you can post pictures.
How do you connect a fire alarm (Such as Wheelock AS) to a smoke detector (Normal smoke detector)
These aren't American fire alarms here these are UK fire alarms
@bluecylinder Carbon Monoxide detector
ion and optical... what's the difference...?
You ask what is the difference between optical and ionisation smoke detectors. There are lots of videos out there that show you, but in short, ion uses radioactive material (americium 241) to detect smoke particles and optical uses infra-red light to detect smoke particles.
is this radiation harmful?
All radiation is harmful .........................if you have enough of it. If it was THAT harmful they would not use it in smoke detectors
A message from me.
Its nice of you to leave comments (Good or bad, but not advertising) but please don't ask can I make a video of (For example) a speaking smoke alarm (They do exist) the fact is I don't have much money left to buy things to test, its not that I don't want to make more videos, its the fact the interesting things to watch cost money.
H.A.N.D.
nice, it would be good if you also had a heat, CO2 and flame detector :D
Can't optical sensor see flames just as well?...it is heat...
Collin Bru You ask can't optical sensor see flames just as well, after all, flames produce heat.
You have answered your own question. You rightly said flames produce heat, but these are SMOKE detectors, not heat detectors.
You missed heat and rate rise ;)
@FireControl9000: Guess again.
I get fed up with people who say (you didn't) CO2 is carbon MONOXIDE its NOT, its carbon DIOXIDE. Carbon MONOXIDE is CO.
Carbon DIOXIDE CO2 is what you find in fire extinguishers.
Carbon MONOXIDE CO is given off by unburnt fuel.
isn't ur thumbnail showing heat detectors
You ask isn't the thumbnail showing heat detectors? The answer is no, its showing the two smoke detectors you see being tested.
Optical is smoke photo ?
?
There is no strobe.
The detectors are connected to a fire alarm panel. Save money, watch my videos.
