A periodic chirp in a smoke alarm typically means that there is a battery backup that has a low voltage (needing replacement) or an alarm that has reached the end of its useful life (assuming it is new enough to include such a feature). If you look up the details in the instruction manual for your particular unit, you may be able to determine which type of problem the chirp (and a perhaps a colored LED) is signalling.
