First Alert and CO/Smoke Listener Compatibility question

Thanks Chelsea. The announcement is a good safety feature that I don’t want to turn off–for example at 2am, I will not only hear the alarm, but smoke or CO and location (there is smoke in the basement vs kitchen) helps me with an escape route.

I have one last idea for the listener test. If I were to put the listener next to the first alert during T3 adn T4, but pull it away during the annoucement, and I get that to work…will it have a negative effect on actual performance (meaning during an actual fire, it will not hear the alarm due to the announcement)? If it won’t, I’ll just wait for technology to change!

All the best. George
