   From website  http://en.allexperts.com/q/Security-Fire-Protection-2247/Firex-chirping.htm
   
   ..."Apparently there's a capacitor in the detector that stores enough of a charge to allow the detector to beep a few times after AC and battery are disconnected. This is why it's important to press and hold the test button after disconnecting battery and AC -- to discharge that capacitor.
   
   They do not have to be disconnected simultaneously. Follow this procedure for each one:
   
   Have you replaced your battery and your alarm still chirps?
   
   If so, try this quick fix. Disconnect the electric harness and remove the battery. Then press and hold test button for 20 seconds. Put everything back together and it should be fine.
   
   
   I hope this helps!"
