Thanks for this I have spent time today on youtube looking at some really ill informed rubbish. over 23 million units in the UK alone and little help explaining how to test properly.
Vanessa Raymundo it would work but you are maxxing out the units reader. The amount of CO in the car exhaust is well above lethal levels and wouldnt prove to be an accurate test on the device. Lethal can be as low as 100-70ppm in some people over a few hours exposure. Car exhaust easily hits 1000+ ppm. If you wanted to see if it worked at all it would be okay, but dont use it as an end all be all test. You can buy specific test sprays that will put CO around the unit jist make sure its enclosed before hand. Lighting a cigarette, match, incense, or whatever and holding it about 8 inches away should also provide enough CO to set off the lowest alarm sequence.
That's according to the standard: the higher the concentration, the less time it'll take to sound the alarm. This is done to avoid false alarms, because low levels of CO aren't immediately dangerous, and a normal byproduct of combustion.
@@GRBtutorials I have a few co detectors one has display, which I have tested. I can have the heater on 4 burner on the stove and the fireplace going co stays at 0. The only 2 times I saw numbers is the time I tested it and the time a piece of wood nearly rolled out of the fireplace and got the entire house Smokey. The fireplace incident made the co level reach 13 and that was no false alarm. False alarm Numbers in the hundreds is crazy. People should be alerted before those numbers get that high
I did this test didn't have incnets but I had similar thing what they use for churches the and blessing charcoal had my. Sandwich bag held the Co detecter inside with hand above the smoke so it would accumulate inside it worked in a matter of seconds thank God for this I was about to return my device to say it didn't work it doesn't work with heat only the smoke
@@Milkmans_Son Yeah, but smoke byproduct of combustion usually contains a lot of carbon monoxide, because smoke is unburnt carbon so it indicates an incomplete combustion, and that's what produces carbon monoxide.
Try this easy DIY way to see if your Carbon Monoxide Detector is working. All you need is a plastic bag, some incense and a metal can or bowl. A timer is helpful but not necessary. For more information on testing go to www.carbonmonoxidedetectorhq.com/testing/.
Be careful subjecting any CO sensor to any process that exposes it to Carbon Monoxide. These sensor work by absorbing the detected chemical and at some point they will be over-saturated and need replacement earlier that it was designed. CO detectors are not like smoke detectors. I do understanding wanting to KNOW if it is working properly but just research how to do it.
Cool so you know the circuit from the button to the alarm works but you still have no idea if the sensor is accurate and doing its job. I'll try the incense myself.
Very usefull video.. I tried my CO detector this was and now I know it works !!! Thank you very much...
Thank you for the advice and the video how to test CO detector.

This was very helpful!
Thanks, now I'll use this for my alarm
Very good, thank you
Why can't it just alarm as soon as it reaches 500ppm?
could ths device be more useful when placed infront of the exhaust pipe of the vehicle?

Very odd that it waits so long to go off.

Its weird how just incence can produce very high levels of carbon monoxide.
Cause it's in a bag.

they are supposed to detect carbon monoxide, not heat or smoke.

Never test this in a fire place.

it is too quiet. Imagine someone is sitting in his room listening to music, how could he notice this silent sound ?
+Sir Avan its not quiet. if you own one you would know. its really loud high pitched chirping!
your logic is weird. if you're watching it on CZcams how can you judge the volume? Did you try turning the volume up?
try THIS easy DIY way to see if your carbon monoxide detector is working. USE THE TEST BUTTON!
+andybub45
and how will you know the sensor is accurate and doing its job?
+hotpapayasalad because a alarm will let you know if it is malfunctioning. or go out and buy some solo CO spray
+andybub45 I have read on several sites that the test button only test the power and the alarm, not the CO detection function.
Cool so you know the circuit from the button to the alarm works but you still have no idea if the sensor is accurate and doing its job. I'll try the incense myself.
using the test button only tests the circuitry of the alarm, not the sensor. that's why whenever I get a new one I grab canned CO and test both.
