All units are manufactured within the past year! This Battery Operated Wireless Interconnect Combination Smoke and Carbon Monoxide Alarm with Voice Location is about the best you can get on the market. This is literally what I have in my own home. This alarm is a photoelectric smoke alarm, a Carbon Monoxide alarm, a wireless alarm and it has voice activation. With the First Alert Wireless Interconnected alarm you can connect multiple smoke and carbon monoxide alarms together wirelessly to create a strong network that will protect you and your family. The offers an exclusive, innovative voice warning system with location alert. When an alarm is sounded, the network will alert you which room caused the potential hazard so you can know where to extinguish the problem. The voice system will say directly where the problem is when the alarm sounds off.
Photoelectric detectors alarm from slow burning smoldering fires much faster than ionization alarms. This is how the majority of house fires start.
The Carbon Monoxide alarm is built in so everything is connected which is the most important thing. A smoke detector puts off about 90 Decibels and the average human wakes up from about 70 Decibels. 1 single closed door can reduce the decibel level by 20 decibels. So if you have one on the floor below you the sound is pretty much non-existent. Children and Seniors take much higher than 70 Decibels to be awoken so now you can see the problem. Now you could call an electrician out to rewire your home to put the cheaper hardwired detectors in but you are going to end up paying $1200-$1500 dollars for them to run all the wires. These alarms solve that issue and go one step furthur. These are the only alarms on the market that will tell you which smoke detector is alarming. If the alarm in your basement is going off then your master bedroom will alarm and say "Smoke in Basement". If there is a Carbon Monoxide emergency it will actually say "Carbon Monoxide in Family Room, Carbon Monoxide level is 500 PPM(parts per million). This is incredibly important so you know where to go and where not to. I offer free phone support for the programming and placement of these alarms. I have installed these in hundreds of homes so I can fill you in on some tips and tricks when you are getting them all set.

5 of 5 Great business and product line February 15, 2021
Reviewer: KEC from Chambersburg, PA United States is top notch.  Good product, best price and fast shipping.  What else could you ask for?  Installed 3 of the SCO500B units and 3 of the SA511N2-3ST units.  They all interconnect with each other.  Instructions from First Alert for setup are a bit unclear, but not too difficult to figure out.  I'm so glad that I found Smoke online and would absolutely buy again from these folks.

5 of 5 Exactly What I Needed February 13, 2021
Reviewer: Anonymous Person from NJ United States  
I have two of these already in my house. The last detector we had left did not have interconnectivity, so when it finally needed to be changed, I made sure to get the updated version to replace it. Connecting them with the other two existing detectors was easy. Hopefully these last just as long.
