Electric smoke detector

I have a question about electric smoke detectors. We have an electric smoke detector in the upstairs (along with a battery operated one) which was installed by the builder. Last night, this detector went off at 10:30 for about 15 seconds and continued to go off intermintently for about 15 minutes. There was no smoke (it isn't a CO detector) and the other detectors did not go off. I flipped the breaker which put an end to the alarm. Then I went to scrape my 12-year old son off the ceiling above his bed.

Any suggestions on why it would go off? It is about 15 years old. Could its age be a factor and that the buzzer was an indication that it needs to be replaced?

If it's 15 years old, it's time to replace it anyway. The house smoke detectors used are very cheap - they are what we call Ionization smokes. Photoelectric smokes are 100X better than Ionization smokes. Ion smokes tend to false alarm a lot and they have also been known to not detect all types of smoke. Whereas Photo smokes use photoelectric beams to detect the presence of smoke.

There's a website somewhere that explains the differences in more detail, but I can't remember where it's at. If I find it, I'll be sure to post it.

If you don't want to replace it, try cleaning it with some compressed air (like the kind in a bottle for computers.)

Good luck!
