smoke detector keeps chirping

Hi Guys,

I have a smoke detector that keeps chirping. I took it down, replaced the battery, hooked it up to the power wire that is coming out of the ceiling, and placed it back in the wall. It is fine for a couple of days and then it starts chirping again like the battery is dead. Any suggestions as to what might be wrong here?

Thanks in advance,

Some of the more recent smoke alarm models also chirp when the sensing chamber is dirty or failing. Double check your battery (things like make sure you didn't put in the tray reversed and that the battery is as good as you _think_ it is).

If the smoke alarm is more than 8-10 years old; I would start over with a new one.
