First Alert SCO500B Interconnected Wireless Battery Combination Smoke CO Voice 12 pack

I bought 5 of these. The system concept is good, as is the setup. But after only a month in service, one of them is giving false alarms and won't respond to pressing the button to silence or reset. So I guess it's $50 worth of trash now. Keeping my fingers crossed on the other 4...Update: Well, I ponied up and bought a replacement for the failed one, and guess what: it was faulty right out of the box. It would not link to any of the others, even though it is the identical model. So I've now bought six of these, and two are faulty. Downgrading this product to 1 star for extreme unreliability.

I wish these would work. The idea is great: interconnected, wireless fire and CO detectors. I bought three. One for each level of my home. Getting all three to connect wirelessly was a pain. Sometimes I was able to connect two but not the third. When I got the third connected one of the first two disconnected. I followed the directions word for word but still was only successful after several attempts. One unit began malfunctioning within three months. I called the company and they sent me a replacement. Again, several attempts to connect them all. After three months one of the units began alarming giving a false positive for CO. I took them all down and replaced them all with different units from a different company. Haven’t had a problem since. These do not work properly. Don’t waste your time and your money.

I purchased this system because my house has 3 floors and I wanted everyone to be able to hear the alarm. These alarms were easy to set up, but the process was deafening (these things are SO loud) which is good but when all of them are int he same place getting programmed, yikes. I liked that I could set the room and when smoke is detected it will say smoke detected in whatever room. I also liked that these used regular AA batteries. I have had these for a few months now and they have gone off several times when smoke or steam was detected. All the alarms on all three floors went off. I moved some of these around and the problem occurs less, these are pretty sensitive a steamy shower will set off the alarm in the hallway by the bathroom if the exhaust fan isn’t one. I’d rather know it works than take a chance on the one our house came with.

My initial thoughts on this model were okay. It took me about 15 minutes or so to figure out how to link 5 smoke detectors together with the right names. Once I got them set up, it seemed like I was good to go. Then smoke from the kitchen made its way to one of the detectors. Never again will I even try linked detectors. I have previously worked with hard wired interconnected detectors. When the problem detector is handled quiet reigns again, as it should. With these, no. I have to address every single detector in the house. They won't shut up. My wife produced me 5 smoke detectors with no batteries in them saying "fix it." What point is that for home safety.Amazon, can I return these?

This is a difficult, even infuriating, product if you have lost the ability to hear upper-register sound or if your hearing is normal and you want to keep it that way.The alarm signal is sent at such a high-pitched range that older people, who often lose their ability to hear high-pitched noise, cannot hear it so they are likely to sleep through all the smoke and fire and poisonous gas.The high-pitched signal is also damaging to one's hearing. And, when the unit sends a false alarm, turning it off is frustrating because it seems to be programmed not to trust the user when he pushes the off button so that it stops for a while but then soon reverts to the ear-splitting alarm once again.When you try to change batteries, the unit wants to walk you through the long, high-pitched, frustrating setup routine that you endured when you initially set the unit up. If you don't do this, you will receive false alarms down the road as punishment. Either way, the people who designed this product have made sure that the users suffer one way or another.When the alarm sounds, you hear the voice of a man with a high-pitched voice in a panic. That's nice because whether or not there is an emergency, it puts you into a panic too.Someone ought to design an alarm that does all the good things that this one does but with less frustration and harm to one's hearing.

I really like the concept of these, but when tested, I've rarely had all three connect at once. Sometimes it's one that doesn't go off with the others, other times it's another. I have to reset these almost every week. Thought that one was a dud, so I tried another (had bought the 4 pack), but same poor results. Wondering what would happen in a real fire if I'm getting mixed results when testing once a week. Assuming they detect smoke better than they connect wirelessly, still a better option than being in one room and not hearing a non-connected alarm going off.
