According the radial flutter extension structure problems in commonly used fire alarm system, a novel topology structure of fire alarm systems based-on holographic crystal forms was proposed. It was composed of multiple devices, including intelligent fire detectors, which can communicate with each other, record fire information and judge, alarms, security, evacuation lights etc. Each device can record all of the information so as to form the hologram. These devices on each floor level in buildings and decorated with vertical layout in the staircase, so that fire alarm system topology based-on holographic crystal forms was set up. The systems can ensure the normal operation of other devices in case that central control equipment failed in extreme cases. And then the automatic fire safety equipment continued to automatically control fire rescue and guide the staff in the correct escape route. Moreover, when a device or a line goes wrong, only failure equipment or system was cut off line, and others were still able to keep communications. Compared with other methods, this new system does not affect the normal equipment of the work.

Fire Alarm System

A fire alarm system (FAS) is one of the most important safety facilities used in any building, and include CCTV and intrusion and panic alarms. Pursuant to the Polish Regulation of the Minister of the Interior and Administration of 07/06/2010, FASs are required in specific civil structures. FASs are directly responsible for the protection of the life and health of humans and animals, and indi-rectly for property at the protected sites. In considering the fire hazards and scenarios, a FAS should be characterized with sufficient reliability. Every FAS is subject to specific requirements in terms of reliability and continuity of performance at the stages of monitoring, FAS failure, and fire. This work is an analysis of the reliability requirements for FAS. Keywords: fire alarm system, reliability requirements, structures.

AbstractA 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.

The issues of ensuring fire safety of industrial enterprises using automatic fire alarm systems is discussed in the article. The foreign and Russian experience of conducting assessment of the efficiency of automatic fire alarm systems is analyzed. Despite the improvement of the regulatory framework for automatic fire alarm systems, the creation of new devices and technologies for detecting fire hazards, the problem of improving the reliability of automatic fire alarm systems actuation remains relevant. Using the statistical data of the federal state information system «Federal data bank «Fires», the calculations were made of the efficiency of automatic fire alarm system actuation at the industrial facilities from 2016 to 2020. Various types of industrial objects are considered: industrial buildings; warehouse buildings (structures); buildings, industrial installations. Calculations of the efficiency of automatic fire alarm systems are based on determining the number of cases of implementation of various modes of its operation. The social and material consequences of fires are investigated considering actuation of the automatic fire alarm systems. When calculating the efficiency of automatic fire alarm systems, the belonging of production facilities to a certain type of property, risk category and branch of industry is considered. Studies showed that the highest efficiency is characteristic of production facilities that are in the federal ownership (90.9 %) and grows up with an increase in the risk category of the object of protection. Thus, for industrial facilities assigned to the category of high risk, the efficiency of automatic fire alarm system actuation for the period from 2016 to 2020 is 92.3 %. By the type of industry, the lowest efficiency of automatic fire alarm system actuation is observed at the fuel industry (62 %), as well as at the construction and shipbuilding enterprises (75 %).

<pre>There are several differences between the two types of alarm systems, conventional systems and addressable systems. It is important to carefully determine the introduction of a fire alarm system according to the installation environment. Talking about the main difference relates to how the connected device communicates with the main control panel by sending a signal. Cost is another factor that can be a determinant of your chosen fire alarm system. In this paper, we proposed smart addressable fire detection system. In the proposed system, <span>IoT</span> was used and the network was constructed using <span>ZigBee</span> module. In the configured network, it consists of a local server and a control server. The local server controls the addressing sensor and sends the information obtained from the sensor to the control server. The control server receives data transmitted from the local server and enables quick fire action. In the actual implementation, the local server used the Lycra controller and <span>ZigBee</span> module. In addition, the control server used the Raspberry Pi and <span>ZigBee</span> modules and connected to the Ethernet so that the administrator could monitor or control the local server.</pre>
