Abstract: The specific requirements that appear in addressable fire detection and alarm systems and the shortcomings of the existing addressing methods were discussed. A new method of addressing of detectors was proposed. The basic principles of addressing and responding of a called element are stated. The sensitivity to electromagnetic disturbances is one of the greatest problems of the proposed addressing method - counting type of addressing. The proposed solutions of this problem were verified experimentally. The paper also gives the conditions and results of the experiment. The counting addressing method was developed for specific requirements in fire detection and alarm systems, yet its speed and reliability justifies its use in the acquisition of data on slowly variable parameters under industrial conditions.
