Ultimate Old vs. New Fire Alarm Dual (3,000 Sub Special) 

I decided to dedicate this milestone with a special project that I’ve been working on for a few months now. I released this much later than I had originally planned to do, because I filmed this back in October. I apologize for my incoherent speaking, at the time I had an illness that somewhat stifled my voice, and messed with my sleep. Also, I spent too much time introducing the devices. 😂
With that in mind, this is a very intriguing project that I worked on, with some rather unexpected results! One of those unexpected results was the fact that the video was over 45 minutes long.
I can’t guarantee that my decibel reader was accurate, because it was just an app on an older iPhone I had, (the XR, for anyone who cares.) Also, this was done in my garage, which is bare plywood wall, and a concrete floor, so some alarms may sound louder than they actually would be in a regular building. 
I was inspired to do this by the user FireAlarm5967. He originally did this by finding out which alarm was the loudest.
