    Good topic. Cringe worthy video. Yikes!

  2. Zach G on September 12, 2022 at 3:32 am

    “What if a fire happens right in front of your eyes” it’s not real until the smoke detector says so

  3. Fredda Pelter on September 12, 2022 at 3:34 am

    Thank you!! So many people do not know there is a difference.

  4. CassetteMaster on September 12, 2022 at 3:34 am

    I’m humored that he went ahead and explained how photoelectric detectors detect smoke, but didn’t explain the ionization–otherwise he would have to mention the Radioactive Material!

  5. J Bello on September 12, 2022 at 3:39 am

    All Smoke Detectors should have a PATH light. Lights saves lives.

  6. BJS 2022 on September 12, 2022 at 3:41 am

    Alarms don’t “go off”. They stay on to sound.

  7. ralph baran on September 12, 2022 at 3:44 am

    The ionization smoke alarm is notoriously unreliable & will allow you to DIE from smoke inhalation / CO poisoning (within the smoke). See Texas A & M 2.5 year study & The Fire That Changed Everything – And What Is Being Done About It… Also Boston Deputy Fire Chief Jay Fleming – his work & research. Examples of this are endless. Want the newest technology? See: UL Releases New Requirements to Smoke Alarm Standards. Should be rated for UL 217, 8th edition & 268, 7th edition. If you want it monitored, recommend an REAL alarm panel with smoke detectors (System Sensor) hardwired & supervised with at least 24 hour backup power. Then you don’t have run around with a ladder, changing dinky 9 volt bats & have higher quality detectors = more reliable. A compatible maintenance module can be connected between the alarm panel & smoke detectors & will alert when they need cleaning. This professional grade equipment’s available online. Residential fire alarm systems, when maintained, are more reliable than retail smoke alarms. Also using a 520 Hz sounder in bedrooms is recommended. The end, please clap.

    Good information, pretty much vital information, definitely a must share video.

  9. P K on September 12, 2022 at 3:45 am

    thanks for the review.

  10. Clarence Taylor on September 12, 2022 at 3:45 am

    I’d expect Bernie to have no less than 10 detectors in his house

  11. Donkey on September 12, 2022 at 3:45 am

    Yes, this may indeed be a smoke detector but it has many purposes example: in our house hold, it tells us when dinner is ready!

  12. Hai Nguyen on September 12, 2022 at 3:47 am

    Anyone ran into a scenario where the beeping is coming from the ceiling and not the detector itself? I replaced my detector with a new one hoping it stops the 5 beeps but to no avail. Anyone?

  13. LoJac on September 12, 2022 at 3:49 am

    Great information… but dang ya’ll made this totally corny.

  14. Jesus Hernandez on September 12, 2022 at 3:50 am

    This reminds me of the SmartPipe infomercial

  16. SteMir ReViews on September 12, 2022 at 3:51 am

    Thanks for top!

  17. Greg Schwartz on September 12, 2022 at 3:56 am

    When will they make a hard-wired smokie that charges the battery so you don’t have to replace it as often?

  18. Eli The Great on September 12, 2022 at 3:57 am

    Fire 🔥: “The rapid oxidation of a combustible material, releasing energy in the form of light and heat”

  19. Mikaiel on September 12, 2022 at 3:57 am

    Stop with the humor, it’s cringey and not even funny.

  20. Jeff K on September 12, 2022 at 3:59 am

    Party on

  21. djfunkychicken on September 12, 2022 at 3:59 am

  22. Clint Decker on September 12, 2022 at 4:00 am

    He reminds me of Keegan-Michael Key, even sometimes acts like him.

  23. Joanne Stealey on September 12, 2022 at 4:01 am

    Also it helps to keep bugs away from it

  24. Producer K on September 12, 2022 at 4:01 am

    Not a good test when the source is right below the detectors. Try again.

  25. HEMP IS NOT POT on September 12, 2022 at 4:02 am

    aloha, please pass along to whomever is the poindexterEinstein at first alert….. all smoke detectors and co2 combo’s need a remote control switch at light switch level in the house. Like the garage door openers have the switch w wires to open and close. This way nobody has to climb a ladder or chair to push a button. HELLO>… WTF.. duh… There should be no need to touch the unit itself, especially if they are gonna wire these together for 2 or more. 
    Make a remote to have an "all off button" and a "Silence button" and the "Test Button" on a panel next to it or somewhere lower so nobody has to climb up the vaulted ceilings at midnight, and so after you find there’s no fire, you can go back to bed and deal with it the next day. 
    Trying to get up from sleep bc the damn thing goes off and dealing with it groggy or medicated on a chair or ladder is more liability than the fire or CO2. Do I have to think of everything…. sweet dreams…Jesus H C people think already

  26. Zakary Cavenaugh on September 12, 2022 at 4:02 am

    Smoke detectors have over a 35% chance of failure. Store bought CO goes off at 400 ppm, and the lethal amount starts at 150 ppm

  27. Steve Seattle on September 12, 2022 at 4:04 am

    "It’s a dangerous test" – I can’t take seriously any advice from people that think lighting 10 sheets of paper is ‘get out of the room’ dangerous. Home owners buy smoke detectors, not 8 year olds.

  28. cplante225cp on September 12, 2022 at 4:05 am

    His name is burn…e.

  29. Steven S on September 12, 2022 at 4:07 am

    I used to have CO/Smoke Detector units in my house — one of the many false CO detections brought my local Fire Dept to my house and they said combo units are the WORST so we have separate units now. Oh, and don’t forget that Ionization fire detectors MUST BE REPLACED every 10 years (the radioactive isotope has a shelf life)!

  30. Micah Hutcherson on September 12, 2022 at 4:08 am

    We used to have a General Electric Home Sentry smoke alarm and I hated the sound it made

  31. Zhou Zoe on September 12, 2022 at 4:09 am

    Dear bosses, I am a supplier of home security products. We have alarms and intelligent linkage products. You can contact me if you need it.

  32. CassetteMaster on September 12, 2022 at 4:09 am

    In truth, there are two types of photoelectric, one, that uses smoke blocking light shining at a sensor, and the other, which reflects light onto a sensor. Then the ionization uses radioactive material to ionize a chamber of air, allowing a tiny electric current to pass. Once smoke enters it, it disrupts the current flow, thus triggering the alarm.

  33. Kyle Hill on September 12, 2022 at 4:11 am

    In the end regardless of local laws it doesn’t really matter how you setup your alarm|(s) as long as they are functional during a fire that’s what counts and you at least have 1 that sounds they’ll be happy when you sell or need fire insurance.

  34. Vatsal Bhandari on September 12, 2022 at 4:13 am

    Two detectors: dual sensor and carbon monoxide. Gotcha!

  35. Alex Su 1404B on September 12, 2022 at 4:14 am


  36. Oliver C on September 12, 2022 at 4:14 am

    What about the main power unit where there is a stop and start red button at the very base somewhere?

  37. Antonio Moya on September 12, 2022 at 4:15 am

    Need to become a member and pay (minimum) $10 each month to get any research Consumer Report Information. Sad shadow of greed. I pass.

  38. GermanCarsRule on September 12, 2022 at 4:18 am

    I would be happy if they quit going off for false alarms and then the annoying chirps in the middle of the night when the batteries are low. I think they are programmed to only chirp between 2 and 4am. Then you have the pleasure of replacing them and testing them. They are rarely easy to get to. They do not turn off easily. Frankly, lots of people end up disabling them completely because they are so damned obnoxious. Also they go off at extreme and unnecessary decibels. I live in a condo so the condo units have a second set of alarms in addition to the individual units and they go off regularly. They can make you deaf.

  39. Michael Lawn on September 12, 2022 at 4:21 am

    i do not have any smoke detectors and very happy

  40. not disclosed on September 12, 2022 at 4:21 am

    I wish they made more detectors that used AA batteries. I also wish they had some with adjustable volume. Not all of us are deaf or need our hearing damaged from false alarms.

  41. watcharapong chantraboon on September 12, 2022 at 4:22 am

    Very safe units to use.

  42. FourTortoise104 on September 12, 2022 at 4:22 am

    The acting… Jesus, take the wheel.

  43. •アノマロカリス• (Anomalocaris) on September 12, 2022 at 4:24 am

    Are they loud enough?

  44. Sirens and Lifts Of Iowa on September 12, 2022 at 4:26 am

    Dual Sensor: KIDDE PI-9010.

  45. S K on September 12, 2022 at 4:29 am

    They don’t mention big issues with fire alarms.
    They will beep obnoxiously when the battery is low, but do nothing else. This can make figuring out which one has a low battery very difficult.
    They are often placed in high places, and getting the plastic battery doors to open is difficult, so replacing batteries is a nuisance.
    Wired systems can alarm,without any way of turning them off, if there is a short circuit/water damage. You have to pull their fuse.
    Often, with wired systems, all the units need to be replaced together or the units will not function properly.
