“…This paper presents operation of a selected FFS with a concentrated structure, with a loop-type line with coinciding sensors. At the beginning of operation (after commissioning), the system displays a significant decrease of the reliability function R(t) -the so called "system infancy" [10,11,20,25]. The decrease rate is S SR (t) = 6,2452E-7.…”

The article presents a selected model of the operation process of the fire system (FSS). The developed fire scenario for the selected building object is possible for practical implementation only with the use of an appropriate functional structure FSS and technical devices from which the system is built with the appropriate reliability and technical parameters. Practical implementation of FSS in a transport facility is the use of elements, devices, fire panels, detectors, etc., which form a specific connection structure. The use of appropriate technical solutions in the system -redundancy, booking and the principle of safe damage causes that FSS has an optimal structure in terms of reliability. The article presents the selected technical structure of the FSS, which was described by means of the exploitation process graph, taking into account the actual damage intensities and the renewal times for selected devices included in the system. A constant intensity of damage was assumed in the FSS operation process due to the initial aging of individual devices that takes place in the production plant. The development of a model of exploitation process for selected operational states and a computer simulation of a selected FSS enables determination of reliability indicators. StreszczenieW artykule przedstawiono wybrany model procesu eksploatacji systemu sygnalizacji pożarowej (SSP). Opracowany scenariusz pożarowy dla wybranego obiektu budowlanego możliwy jest do realizacji tylko z zastosowaniem odpowiedniej struktury funkcjonalnej SSP i urządzeń technicznych z których zbudowany jest system. System powinien się posiadać odpowiednie parametry niezawodnościowo-techniczne. Realizacja praktyczna SSP w obiekcie to wykorzystanie elementów, urządzeń, central sygnalizacji pożarowej, czujek, itd., które połączone instalacją tworzą określoną strukturę o wyznaczonych relacjach przez projektanta. Stosowanie odpowiednich rozwiązań technicznych w systemietj. rezerwowania i zasady bezpiecznego uszkodzenia powoduje iż SSP posiada optymalną strukturę pod względem niezawodności. W artykule przedstawiono wybraną strukturę techniczną SSP, którą opisano za pomocą grafu procesu eksploatacji uwzględniając rzeczywiste intensywności uszkodzeń i czasy odnowy dla wybranych urządzeń które wchodzą w skład systemu. Założono stałą intensywność uszkodzeń w procesie eksploatacji SSP ze względu na wstępne starzenie poszczególnych urządzeń które ma miejsce w zakładzie produkcyjnym. Opracowany model procesu niezawodnościowo-eksploatacyjnego dla wybranych stanów i symulacja komputerowa w wybranej aplikacji umożliwiają wyznaczenie odpowiednich wskaźników użytkowania SSP.Słowa kluczowe: niezawodność, systemy sygnalizacji pożarowej, eksploatacja, model

“…It usually takes a value equal to 1.25 [1,94]. All FACUs have their own, extensive and stabilized power supplies supervised by microprocessor systems in terms of output currents and voltages [96][97][98]. There are additional filters inside the power supply, which eliminate interference occurring within a power mains-e.g., harmonics [94,99,100].…”

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.
