In this video I show how to install smoke detectors and carbon monoxide detectors. I explain my local building codes I must follow for my inspection to pass. I show how to hard wire smoke detectors that are battery back up. The smoke alarms I am installing are the First Alert BRK model. Hope this video helps!

Always make that good connection by twisting the wires together with lineman's. Some will only use the wire nut. I've seen problems with bad connections resulting in low voltage conditions. Tip: Stranded wire should always be cut back a little longer when connecting to a solid wire connection. Tip 2: Photoelectric smoke detectors are more sensitive as they use light wave to detect smoke; whereas Ionic has a radioactive chip in it to sense more heat - that is what would determine placement between a bedroom vs a kitchen to minimize false alarms. All smoke detectors need to be dated on install and then disposed of properly at their retirement. As always - Great Video!

One of the most important steps when using wire nuts is not shown in this video. That is- after you are done twisting it on, pull on each of the wires one at a time and see if any pop loose out of the nut. When my smoke alarms were 10 years old I went around my house before removing the old ones and I pulled on each of the wires. About 1/3 to 1/2 of the units had one or more loose wires! So of course putting in the new alarms meant redoing ALL the wire nuts.

Its great that he is putting up smoke detectors, but somethings need to be noted. Smoke detectors should be placed 3 feet or more from the ends of a ceiling fan, 3 feet away from a central a/c or heat outlet, 3 feet or more from a bathroom door and 12 inches or more from any room or ceiling corner. Carbon/smoke combs. need to be placed outside of all bedrooms, within 10 feet of ALL bedroom doors. One carbon/smoke comb. can cover more than one bedroom, it they met the10 foot rule. If a room has a closet, just to be safe, assume it will be a bedroom, install the smoke detector inside and the carbon/smoke combo. outside. Some areas say that you don't need a carbon, unless you have gas in the house or an attached garage. Be safe, pretend you do. In this video, as others noted, in the outlet box, which is actual a wall outlet box, use a 6/32 size machine screw, NOT a sheetrock screw, you picked up off the floor. If it is a round box, you must use a 8/32 machine screw. When putting the wires together for the wire nut, DO NOT TWIST THE SMALL, STRANDED WIRE, from the wire, of the smoke detector. Extend the small, stranded wire just a bit in front of the larger solid wire and twist the wire nut on, it will twist the small wire around the bigger wire fine, then do a small pull, to see if the smaller wire, is secure in the wire nut. The ground wires are connected together with a crim sleeve.

Oh wow did not know that these were not grounded. I am glad my "experiment" I did, did not end in flames. xD I thought the red was the ground and hooked it up as so. I was not sure about the red but now I do know. ;) I said it was an experiment as I was perplexed at being able to buy carbon menoxide detectors that plug in with battery back up but no smoke alarms that plug in. So I was like I have this 3 prong that came out of one of my pinball machines that I had replaced but nothing wrong with the cord it was just to short is all. I used Wago electrical connectors to wire it up and wrapped electrical tape around the Wagos to to make sure the clips did not come up. And plugged it in and it is working fine. And I now know that the smoke alarm does not like it if there is no battery in it as I was so confused at why it was chirping at me. I was like maybe put in the battery? I did and sure enough the chirping stopped and now I have a plug anywhere smoke alarm. And after seeing this video I think I am going to unhook the ground and red wires off. Or at least take the ground out of the red Wago connector. I did make a video of it as well and pretty much put in a joke title of like, Well did this experiment burn my house down or did it not kind of thing. I am glad it did not explode or anything. xD

IRC code 314.20 says the front edge of the box can not be more than 1/4 inch set back from the finished surface. When installing before drywall you place the box out 1/2 inch from the surface the drywall will be attached to, assuming you are installing 1/2 inch drywall, so it will be flush with the finish.

In the near future those ionization type detectors will no longer be meeting the UL 217 standard because they are unsafe as they don’t detect smoldering fires well, and also because they false trigger for kitchen cooking too much. A better choice is to use photoelectric type smoke alarms. These work well for all fire types.

There is a very important technique to use when joining stranded with solid wires using a wire nut. The stranded wire should be stripped to a longer bare length than the solid, and the extra length should extend beyond the tip of the solid wire when the wire nut is first applied. This video is a great example of the wrong way to join stranded with solid as this critical step was omitted. If you are not an electrician and are joining wires and want to do it right and safely, using a Wago 221 lever nut will work better than what you see in this video.
