The method for wireless information transmission within an alarm system operates in such a way that, at the instigation of a sync pulse transmitted from the central station, a response telegram is transmitted back by each alarm detector (1, 2, n) in turn. This response telegram contains the status of the alarm detectors. The response telegrams are transmitted back serially in a plurality of cycles until a new sync pulse from the central station (Z) initiates a new polling cadence. <IMAGE>
