Combined smoke and CO2 is the way to go if you have carbon fuel heating, dryer, or stove. Setting up is a bit of a pain because the verbal instructions blare at full volume, but that is a one time thing. One on each floor plus the laundry and furnace rooms. Plus a fire extinguisher near kitchen. Pretty laid back person and never had to depend on these items, but it's the cheapest insurance you can buy.

Charles Napper: These First Alert Battery Powered Wireless Interconnected Photoelectric Smoke and Carbon Monoxide Alarms, replaced my old Kidde units that did not Communicate with each other at all. The First Alert's are loud enough to wake you up, when a emergency is detected on any level. Unit's were easy to set up and install, batteries included... I recommend these for anyone who need to replace there old smoke detectors.

bizperson: I purchased two of these after being unhappy with First Alert ZCOMBO made for Ring, which I returned. This model interconnects with other SCO500B models so that if there is an alert in another part of the house, all alarms beep and give a voice alert. These units cannot connect to my Ring Alarm system. That is fine with me as I discuss in my review of the ZCOMBO model. I had no problems at all with setting up these two units and choosing the voice location feature. So far, no false alarms and the units are working fine. I have read the "one star" reviews and people have had false alarms after a period of time. Mine have been up for one week with no problems but if I start getting false alarms, I will update this review. The distance that these interconnect seems good as I have tested these two in different parts of my house. I will probably buy two more for other areas. One thing that I like about this design is that if it detects CO, the alarm goes off and then it speaks the CO level to let you know how much CO has been detected.
As I discussed in my other review of the ZCOMBO unit, people should not just assume that getting a CO alarm means that the unit is broken. There...

M. Pickering: Smoke and Carbon Monoxide detectors/alarms are extremely important for every home. People hate to spend the money on them, especially the higher quality (more expensive) detectors, and yet your very life can depend on them. There are many choices on the market today, ranging from cheap, basic models to extremely expensive, high-tech devices. There are two main types of smoke detectors: ionization detectors and photoelectric detectors. Most detectors utilize either one or the other of these technologies while some use both. Most detectors just use a beep-style audible alarm, while some talk, some have strobe lights, and some have a bright light to illuminate a dark area. Many detectors today are combining a smoke and carbon monoxide sensor, so you have dual protection in a single device. You can choose between AC and battery operated devices. Most (if not all) new homes are built with AC detectors in all of the vital areas, which usually contain a battery backup in case of a power outage. Many of these new detectors, installed in new homes, are linked together so that one detector will trigger all of them to sound their alarm. This is a very useful feature, since an alarm in the...
