The smoke alarm in our bedroom was pretty old, so I decided that I wanted to get a new one to replace it. I went to Home Depot, and I saw the First Alert SA302. This smoke alarm uses both photo and ion detectors to determine when there is smoke in the room. Since this was going to go in our bedroom, I wanted a alarm that could detect smoke from any type of fires.
This alarm also has a "Remote Controlled silence/test" feature, where you can use your TV remote to silence false alarms and test the alarm. I though that this would be a good feature, because then my wife wouldn't have to get on a stepping stool to silence the alarm.
The problem arose when we were watching TV that night. The IR detector was sensitive enough that just by changing the channel on the TV, the alarm was going off. (And we weren't even pointing the remote anywhere near the alarm.) We removed the battery from the alarm, and the next day we replaced it with a alarm that doesn't have a IR sensor.
I am sure that this is a good smoke alarm, but just not in a room that has any devices that have a IR remote.
