A fire alarm system (FAS) is a system comprising signalling-alarm devices, which automatically detect and transmit information about fire, but also receivers of fire alarms and receivers for damage signals. Fire alarm systems function in different environmental conditions. During operation they should be in state of fitness. This is determined by the reliability of the assembled units and rational management of the operation process. Therefore a reliability and operational analysis of fire alarm systems as a whole is essential. This article presents an authorial model and an operational and reliability analysis of FAS, which is exploited in a transport building. It also demonstrates relationships occurring in the analysed system, where to an addressable fire alarm central unit with detection loops and control-monitoring loops alarm device lines (with monitored relay outputs for actuation of alarm-signalling devices) were connected. Research and analysis of results for representative FAS, which were exploited in similar environmental conditions, were conducted in order to determine operational and reliability parameters of the investigated system. FAS computer simulation was run during the time t = 1 year of safety system operation. This led to the calculation of the probability value of the analysed FAS staying in the examined operational states.

“…Zastosowane środki transportu drogowego powinny cechować się określonymi wartościami wskaźników niezawodnościowo-eksploatacyjnych [5,10,26]. Na niezawodność pojazdów wpływa niezawodność elementów składowych i zastosowane struktury nadmiarowe [2,4]. Pierwsze rozwiązanie zapobiega uszkodzeniom, zaś drugie prowadzi co prawda do rozbudowy systemu, ale umożliwia tolerowanie występujących uszkodzeń (stany częściowej zdatności).…”

“…The applied means of road transport should be characterised by certain values of reliability and operation indicators [5,10,26]. The reliability of vehicles is affected by the reliability of components and the applied redundant structures [2,4]. The first solution prevents damage, although the second one leads to the system expansion, but it allows for tolerating the occurring damage (states of partial fitness).…”

Modern vehicles are equipped with telematic on-board systems, which connect electronic devices between them. The sent data are among others used to control systems and devices. They also have a certain operational potential. They can, indeed, also be used to rationalize the technical service of the vehicle fleet. This publication presents the author’s graph of the operation process, including the monitoring of the vehicle fleet. The application of the presented approach will contribute to the improvement of the value of certain vehicle reliability and operation indicators.

“…The first solution is aimed at preventing damage. In the second case, the use of redundancy, although leading to an expansion of the converter, enables tolerating the occurring damage (through the introduction of the impendency over safety states) (Caban and Walkowiak 2019). The quality of information Stawowy and Kasprzyk, 2015;Stawowy and Siergiejczyk, 2017; obtained by systems from the sensors (Dabrowski et al, 2012;Kaniewski et al, 2017;Łabowski and Kaniewski, 2015;Reddig et al, 2018;Bednarek et al, 2019) is also important during a reliability-exploitation analysis.…”

The paper presents issues associated with the impact of electromagnetic interference on static converters, which exploitation in a railway transport environment. The measurements of an electromagnetic field emitted by a static converter were shown. Designs of this kind are exploitation in railway facilities, therefore, they should not disturb the functioning of other equipment, the rail traffic control systems, in particular. As a result of the EMC tests, it was concluded that the permissible values of conducted interference emissions were exceeded. An analysis of the obtained results enabled developing a research model, and a further reliability and exploitation analysis, taking into account electromagnetic interference. This, in turn, enabled determining a relationship allowing to determine the probability of a static converter staying in a state of full ability. The presented discussions regarding a static converter, taking into account electromagnetic interference, allow for the numerical assessment of different types of solutions (technical and organizational), which can be implemented in order to mitigate the impact of electromagnetic interference on a system’s functioning.
