“…The semi-anechoic chamber creates a shielded space in which all inappropriate electro-magnetic interferences from the environment that could distort the measurement results are eliminated. [8] Used semi-anechoic chamber from manufacturer FRANCONIA was equipped with the logarithmicperiodic antenna HL046 (Rohde&Schwarz) (Fig. 2) which operates in the frequency range from 80MHz to 1.3 GHz.…”

Abstract. One of the major types of electromagnetic interference, which affect electronic devices in their normal operation, is the interference with radio-frequency electromagnetic fields. This interference is generated by the mainly radio and television transmitters, industrial equipment and other transmitters and receivers in general use for communication. Testing of electromagnetic susceptibility of electronic devices on radiated radio-frequency electromagnetic field is governed by the basic standard IEC 61000-4-3 and the equipment under test are exposed to test electromagnetic fields with an intensity from 1 V/m to 30 V/m, the most often in the frequency range from 80 MHz to 2 GHz. The aim of this paper is to explain the issue of electromagnetic susceptibility and to present sample the electromagnetic immunity tests of the basic set of the intrusion and hold-up alarm system against the radio-frequency electromagnetic field according to the relevant electromagnetic compatibility standards.

Abstract. The Fibaro is a system for automation of smart households, which ensures not only the functions of comfort and power saving, but it also offers the security functions. These security functions were checked and examined in this paper from several perspectives. The evaluation of two submitted model realizations of Intruder and Hold-Up Alarm Systems (I&HAS) with using of the Fibaro system was presented: the Proprietary model, which works with manufacturers' detectors, and the Integration model including the standard loop I&HAS to the Fibaro system. These comfort functions were examined in this paper from the point of view of the functional safety and fulfillment of the normative requirements for the I&HAS. The examination of functional reliability consisted of verification of the ability of the control unit to correctly respond to changes in detection conditions inducted through the relevant sensor. The functional tests were conducted in several steps. Thanks to the functional tests the unreliability of the control unit Fibaro HC Lite to register a larger number of detection messages had to be confirmed. The result of this work was the demonstration of inappropriateness of utilisation of installations according to the Proprietary model. Simultaneously the Integration model was evaluated from a point of view of valid norms with assigning of the first security level, however, the conditions unaffected the I&HAS.
