Narrative:
While being radar vectored to avoid thunderstorms along our route of flight; we received a cabin altitude alert warning indication light from the aircraft. We asked for and received an immediate descent to 24000 ft and later 11000 ft. We subsequently donned our oxygen masks and began running through the checklist; however; cabin pressure remained normal. We were radar vectored to the ILS where we made a precautionary landing without further incident and taxied to the ramp.
