No, in fact, the beacons of Gondor were only used to alarm the men of Anórien (and the southern beacons to alarm those of the southern fiefs). The King of Rohan was informed of the war by the Steward's errand-riders, who brought him the Red Arrow. (That's something the movies got wrong, I'm afraid)
