Kidde Dual Mode LED Strobe Light, AC

hey thanks for joining me at Frank's DIY and homeowner help today I do a pretty easy job have I said that before it hasn't worked out well this should be easy this is just reinstalling this smoke alarm carbon monoxide detector system so here's the old one again I lived been living in this house for six months it's a new build over a rebuild and it has these hardwired smoke and carbon monoxide detectors these are pretty high-end units they're they call them a three-in-one it's got an LED light that strobes for those that are hearing impaired or hard-of-hearing and it's got an audible warning to it'll yell at ya and tell you whether it's smoke or carbon monoxide or fire type of thing so that's kind of neat although I don't really think you need that but it's it's also a 10 a 10 year battery so it's got a built in battery backup so these are hardwired to your volt your houses electrical sy
