I concur with the above comments.

The alarm was so deafening you couldn't hear yourself think, much less hear a telephone. So I needed to carefully make my way across the house to silence the alarm panel located in the kitchen. As I was leaving the master bedroom it was apparent my long gun was too difficult to effectively operate around corners, so I back tracked and retrieved my SP101 .357 revolver loaded with Critical Defense ammo.
Admittedly, I'd never practiced clearing my home as I never expected to. Never even thought about what would happen if the alarm went off and how I would silence it from the bed room. Learned a few valuable lessons and holes in my security that night.
Fortunately, it turned out to be a false alarm from the basement motion detector. I'm guessing a spider might have walked across the face of the sensor? It took the Sheriff's deputy :30 minutes to find and get here, as I'm not trained or comfortable to clear my house myself.
Also from first hand experience, if you have a watch dog indoors, when that siren goes off, mine went yelping and running around like crazy from the ear piercing siren. That's another distraction to be aware of.
I disagree with #7-1/2 bird shot not being a man stopper at home defense distances. I've shot spoiled meat, watermelons, cantaloupes, garden vegetables at 5-7-10 yards for sport in the back yard. Nothing left except a nice "garden salad"!
First, you need to understand most handguns are crap fighting weapons. Handgun rounds at handgun velocity only damage the tissue directly in front of them. They crush tissue. Rifle rounds on the other hand, traveling at about 3 times the velocity damage much more than the tissue directly in front of them. Almost any rifle round will have superior 'stopping power' than any handgun round.

Fourth, I have accessories attached to the rifle that enhance the effectiveness of the platform such as a weapons light, sling and red dot sight. Lastly, with the properly selected ammunition the .223 cartridge will penetrate less than a 9mm or .45, even when they're loaded with quality JHP ammunition. Just released today, here is Brassfetcher's slow motion footage of an M193 5.56 cartridge in ballistics gelatin. 5.56x45mm 55gr FMJ M193 slow motion ballistic gelatin - YouTube This is FMJ... now compare that to a premium defensive loading in 9mm: SLOW MOTION 9x19mm Luger Remington 147gr Golden Saber impacting ballistic gelatin - YouTube

Shotguns are also excellent stoppers. A 00 buck load is similar to 8-9 handgun bullets traveling downrange at once. This video shows buckshot vs handgun rounds in ballistic gelatin.
