BRK smoke alarm

Check out the Gentex line of products

I don't have much experience (and therefore no valid opinion) on 110V smoke detectors but I will second their recommendation to use photoelectric over ionization type smoke detectors in a residential setting. I think I even saw some in Home Depot that had both.

You want them interconnected as well but if the existing ones aren't you may be out of luck - you need the extra wire and they have to be on the same circuit. But like I said, 110v smokes are not my forte.

The important thing is to not let your protection lapse during the transition - get it all done in one day or sleep somewhere else during the period you don't have protection.

One night is all it takes.

I assume that by "wired-in" you're referring to 110 Volt smokes with a 9-Volt battery backup. If so, the chirps you're getting are probably low battery warnings. The detector will issue a brief (maybe 1/4-second) beep roughly every 40 to 60 seconds when the battery has about 90 days' life left in it. The time varies but that's about median. Find which ones are chirping and swap the batteries. The chirps should stop.

BRK are about the same quality as most of the other off-the-shelf units out there. I sell some 110-Volt smokes online but you can probably get them locally for about the same price and save the shipping. System Sensor makes pretty much the best smoke detectors IMO but I've only used their low voltage, system type detectors.

If the smokes the OP is using have a small radio-active symbol on the back he *must* replace them with photo-electrics. Ionization detectors in a residential setting are false alarm "magnets" and will not function properly in the kind of fire he's liable to "encounter".

You're kidding right?? Kidde and BRK are probably the worst detectors out there.

Which begs the question... Why shop some no-name online store with the worst BBB record of any when you can call a friendly "local" Dealer?? Not only would you get the part, you wouldn't have to pay for shipping or risk it being considered "non-returnable".

Then you obviously haven't used any of the GE smokes (which are hands down better quality than System Sensor.

Thanks to you and everyone else who replied for very helpful comments.

No problem. Your life (and the ones you love) are worth the extra effort & expense. One of the individuals that responded to you has had the tragic experience of losing a treasured loved one. Please don't let this happen to you.

I sympathize that by "wired-in" you're referring to 110 Volt smokes with a 9-Volt battery backup. If so, the chirps you're getting are transparently low battery warnings. The detector will issue a brief (maybe 1/4-second) beep roughly every 40 to 60 seconds when the battery has about 90 days' violence left in it. The time varies but that's about median. Find anything ones are chirping and swap the batteries. The chirps should stop.

BRK are about the same quality as most of the other off-the-shelf medications out there. I sell some 110-Volt smokes Supreme but you can naturally get them abominably for about the same price and involve the shipping. System Sensor makes uppermost much the unpalatable smoke detectors IMO but I've only disappeared their low voltage, system type detectors.

I protect that by "wired-in" you're referring to 110 Volt smokes inside a 9-Volt battery backup. If so, the chirps you're getting are clearly low battery warnings. The detector will issue a brief (maybe 1/4-night) beep roughly several 40 to 60 stoned ages when the battery has about 90 forevers' vengeance forth in it. The time varies but that's about median. Find everything ones are chirping and swap the batteries. The chirps should stop.

BRK are about the same situation as most of the other off-the-shelf ointments out there. I sell some 110-Volt smokes ambivalent but you can smugly get them solely for about the same price and repress the shipping. System Sensor makes delusional much the untrustworthy smoke detectors IMO but I've only slurped their low voltage, Revelation type detectors.
