“…Electronic security systems, due to their particular objectives they must fulfil and the entailing high responsibility, must be characterized not only by high reliability in terms of the hardware [47][48][49], but also understood as a decision on the security of a monitored area, created based on data collected previously from the aforementioned sensors. It should be noted that, in the context of the described studies, especially the second of the aforementioned aspect may be considered as a diagnostic and measurement issue.…”

“…An important issue that should be taken into account within the FAS operating process are electromagnetic interference [32,43], maximum permissible temperature changes in rooms with installed detectors [47,48] or accelerations of vibrations and shocks in electronic elements [10,49]. Within the studies discussed in the aforementioned articles, individual factors disturbing the FAS operating process are considered separately.…”

“…The presence of electromagnetic interference and abrupt external environment parameter changes can lead to an increased probability of a false alarm by FAS installed in buildings or over a vast area [14,15]. This may result in serious consequences, e.g., economic, such as suspending transport traffic, air, or rail, as well as announcing the evacuation of humans through an audio warning system (AWS), directly or indirectly connected to a fire alarm control unit (FACU) Figure 1 [16,17].…”

Selected Issues Associated with the Operational and Power Supply Reliability of Fire Alarm Systems

The article reviews issues associated with the use of electronic fire alarm systems (FAS). They are operated in various environments and buildings with varying volumes. FAS have to function properly under different operating conditions associated with their operation, as well as power supply and information inflow. Due to their functions, i.e., ensuring the safety of people, vehicles, logistics bases, airports, etc., FAS have to exhibit an appropriately organized reliability structure associated with their implementation and power supply. Operational studies involving FAS operated in various facilities were conducted to this end. The authors determined damage and recovery time intensities. FAS reliability indicators were also determined. The article presents graphs associated with developing the energy balance for selected FAS. The graphs are consistent with the latest and applicable legal regulations. The next stage of the work related to this article was developing an FAS operation process model and conducting computer simulations in order to determine reliability indicators. Such an approach to the FAS operation process enables a rational selection of technical and organizational solutions aimed at guaranteeing reliability in the course of executing operational tasks associated with ensuring fire safety. FAS operational analysis, developing balance graphs and models, as well as the computer simulation, enabled inferring conclusions that might be useful to the process of engineering and operating such systems.

“…The safety of transport facilities is as important as transport safety (Losurdo et al 2017;Stawowy and Siergiejczyk 2017;Klimczak and Paś 2020). Transport facilities are widely equipped with safety installations, especially with fire alarm systems (FAS), acoustic warning systems (AWS), smoke ventilation systems and fixed extinguishing devices both water and gas based (Ge et al 2017;Østrem and Sommer 2021). These mentioned systems control signal boxes, distribution boards, teletechnical containers on level crossings, railway stations and railway platforms.…”

The analysis of the operational process of a complex fire alarm system used in transport facilities

et al. 2021

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.
