In this video I go over some code requirements for smoke alarms. Specifically these are requirements in Minnesota and you should absolutely consult the code in your area, but these are very general requirements and will be very similar to what I mention in this video.

Perfect video benjiman
thanks for the video I have a question I'm running in a new construction like 11 detector can I split the wiring for different rooms?
very informative post ! btw, do you know if smoke detectors should be a certain distance from heat/AC registers by Code ? thank you in advance.
Minimum 3 feet
it's important to use photo-electric or dual sensor alarms - ionization only don't detect smoke from smoldering fires until the concentration is lethal.
You must also have 520 HZ frequency alarm sound as well, at least in sleeping areas.
Also, connecting the smoke alarms to the audio system is a good idea.
Thanks for sharing your experience and for being a subscriber! Blessings from Minnesota!
@@BenjaminSahlstrom What happens if your not full local compliance yet you still have working fire protection not letting it fail thus meeting minimum standards of working detectors?
The best option is to sprinkle your house with photoelectric, ionization, and CO detectors so you cover all areas. Last I check they don't make an alarm that covers all three.
Good stuff!
Couple questions though. Do smoke detectors count in the number of devices allowed on a 15A circuit? And can they be on a general lighting and receptacle branch circuit that has 12 devices, or at least make up a portion of the 12 devices if each detector is counted as one device? For example, if I were to have 5 receptacles and 5 lights, would adding 2 smoke detectors bring me to 12?
i realize it is kind of randomly asking but does anybody know of a good place to watch newly released movies online ?
@Leo Amari flixportal :D
@Cyrus Noe thanks, signed up and it seems like they got a lot of movies there =) I appreciate it !!
@Leo Amari Glad I could help xD
Those inspectors recomended to benefit companies to sell more smoke detectors and install in every bed room which is in fact not needed.
New Jersey house built in 1970, now on the market. Are smoke alarms required in each bedroom? My realtor says no. She says one on each floor. I'm not so sure of that. What say you?
Hey Benjsmin, I never run wire for smoke detector. have you a video when you explain abou it?
Running the wire is simple, just 14/2 from panel to the first detector and then 14/3 from each detector there on. The 3rd/red conductor carries the signal to the other ones when it detects a fire.
@@MyFortressConstruction It seems dangerous to not have an over current protection you can't easily manage. Too much can go wrong not having a dedicated circuit even at the risk of someone foolishly shutting it off it's still better to have the ability to quickly isolate detectors.
@@MyFortressConstruction thank you! What amps am I using for these 14/2 then 14/3??
Is 15 amps work ?
@@poisuon141 Yes, 14 ga. wire is rated for use with a 15 amp breaker throughout out all jurisdictions and codebooks that I'm aware of.
What happens if you HAVE smoke alarm protection but are not in full compliance yet you still have working protection not letting it fail?
They're going to force their stuff on us it's ridiculous
I am trying to find the breaker for my 20 yrs old smokes so I can replace them. I turned all the breakers off in the the elect panel and the smokes are still hot. Any ideas?
How did you verify they are still hot?
Well I have a smoke alarm
@@MariaRodriguez-gi6vf This is why they should be on a dedicated circuit. This government overreach is nonsense. If they had a regular circuit you'd know they were turned off by finding the right circuit and seeing no power on the LED light.
link the document at the start of the video!
Why not put rate of rise heat detector in your kitchen
I agree!
Great video man, however just as a heads up to anyone who watches this, it is NOT a good Idea to rely on combonation smoke/carbonmonoxide(CO) detectors for your safety. A CO detector should be mounted about knee level due to the fact that CO is heavier than air so it settles low first. Long story short, if a combination smoke/co detector that is mounted on or near ceiling level is triggered by carbonmonoxide the occupants would all ready be dead due to CO poisoning. Not trying to be mean or anything, just trying to make people more aware. Other than that this is a great and very informational video.
Thanks for sharing your thoughts. Very excellent points.
You are incorrect about (CO). Its actually lighter than air. They should be placed at least 5 feet from the floor. Look it up. You might be thinking of Propane (LP) detectors. They are the heavy gases. They need to be installed about a foot from the floor.
Actually, CO mixes with air evenly, it has pretty much the same mass, so it does not matter where to put it.
@@maxpopko8594 Im glad to see it repeated i use to work with a buffoon who would say co is heavier than air to customers from ATT digital life no matter how many times i told him he talked nonsense in his co beliefs.
@@maxpopko8594 Came here to say this. Anybody reading this is going to be like "I am hearing three different things in this one comment thread". I have been designing FA/CO systems for 5 years now. The industry consensus is 100% in agreement that CO mixes with air evenly and we design our systems accordingly.
Do. Not? Tie the fire. Alarm? Units into the lighting circuit fire. Alarm? Units or F. A u circuit is a dedicated circuit. It does not share
Smoke detectors should be on a dedicated 15A circuit, not tied to a lighting circuit.
What if the breaker trips and you are unaware of it?
@@owenjennings8575 Most interconnected & hardwired alarms will either beep from low battery and/or loss of hardwired power. So unless the batteries are removed and the breaker is off, then you'll likely know there's an issue regardless of lights--Also, you're supposed to be manually testing the alarms periodically.
Jacob Garrett Heimberger thanks.
code where i am requires smokes be put on lighting circuits.
You can connect your alarm system to another circuit. But I do recommend a dedicated circuit for the alarm system.
