Tools and Hardware Reviews of First Alert SA302CN Double Sensor Battery-Powered Smoke and Fire Alarm
Customer Review: Irritating battery replacement procedure
Summary: 1 Stars
As others have pointed out, this unit works fine as a smoke detector, but the battery replacement procedure is painful. The battery expired around midnight. It immediately starts to chirp every 15 minutes so it can't be ignored until morning. I replaced the battery and it continued to chirp. Thinking the battery I found was dead I replaced it again, twice. Turns out after replacing the battery it can chirp for up to 15 minutes even though the new battery is fine. Of course I found this out through Google after an incredibly annoying sleep deprived hour.Customer Review: It may be good for unoccupied spaces
Summary: 2 Stars
I bought 3 of these via Amazon. Unknown to me, they arrived dirty, with out of date batteries. As a result, they caused many false alarms. We weren't home for the first two, and the neighbors called the fire dept. My advice is to clean them thoroughly per the instructions and discard the batteries that come with them.
They are much too sensitive. They can't be installed near the door to a bathroom in which there is a shower. They can't be installed anywhere in a kitchen. As others have pointed out, they can't be installed in a room in which the TV remote control is used. In my case, the above rules leave only the basement.
In any of the above locations, a fire dept officer told me to use only photocell detectors, not ionization. They are not as sensitive.
Customer Review: It will save your life, but mount in the correct place.
Summary: 5 Stars
This thing is very sensitive. It is above a door near the exit in our kitchen. It went off when I was making toast nearby. It goes off when we cook too, so I pulled it down and put it in the closet. Had I put it in another room, I'm sure it would be great. I mounted it there because I was replacing another smoke detector that was there when we bought the house and the previous owners painted around it. I highly recommend it, especially near the bedrooms, I am sure it is great.Customer Review: Junk
Summary: 1 Stars
I have sent several of these back to First Alert because of alarm codes that say the unit is bad. At one location ALL that I've put there eventually give the bad code when the nearby light is turned on. First Alert suggested we move them away from the light source. I guess that means these can only be used is the dark. Moving all of mine to dark closets does NOT seem like a proper solution to an obvious design defect.Customer Review: Lithium Battery does NOT last 10 years!
Summary: 4 Stars
Although the included battery is marketed as a "10 year" battery, we found itlasts less than three years. And the battery has a 10 year warranty which explicitly omits any warranty of battery service life! So the 10 year claim is strictly hype, and misleading.
