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.

“…A typical modern FAS consists of a fire alarm control panel (FACP), initiating devices (i.e., detectors or sensors), notification appliance (such as a flashing strobe light, an electromechanical horn or siren or combination of these devices), safety action mechanisms (such as door release, gas valve release, automatic phone call to fire brigade), and power supplies (including backup power supply) [20]. The fundamental of FAS also applies to the IoT based FAS, but as an addition, the devices and FACPs are now fully connected with cloud server via internet for unified management.…”

This study presents a fail-safe wireless communication architecture for Internet of Things based fire alarm control panels. In fire safety industry, one of the most important issues is to ensure the key information be delivered. A radio frequency wireless communication link is considered for enabling the fail-safe feature when the primary Internet of Things link is failed. In this paper, the design of the wireless communication architecture is proposed, and the system hardware based on customised micro-controller and wireless communication processors is implemented. In order to examine the performance of the proposed wireless communication architecture, a long-term evaluation is designed and conducted in an industrial warehouse, to demonstrate the information latency with parameter of round-trip time, and system reliability with parameter of probability failure rate. The experimental results show that the proposed wireless communication architecture could achieve the low latency and high reliability requirements and reduce the chance of key information loss. With the multi-disciplinary findings discovered, the proposed wireless communication architecture is feasible to be considered to use in future Internet of Things based fire safety products.

“…To solve these problems, they develop an addressable fire alarm system. One of the features of the addressable fire alarm system is that it is possible to upgrade existing fire alarm systems only by replacing the existing detectors with addressable detectors without changing the wiring [7].

Abstract. Fire alarm systems are essentially installed in specific firefighting equipment and serve as one of important alarm equipments which senses fire early. The main goal of the study is to find methods for improving the structure of fire alarm needs. This study is about false alarms of fire indicating equipment in fire alarm systems. It is found that false alarms false alarms by fire alarm systems are constantly occurring and fire safety manager is neglecting his duty of work by turning alarm bell stop switch on even during usual times. To prevent this, the alarm bell stop switch should be changed into an automatically resettable manual operation type so that it can automatically reset to its original state even though fire safety manager turns the switch on. As a result, aid in correcting fire safety managers' wrongful practices by making the alarm bell ring whenever an actual fire occurs, and ultimately reduce false alarms by eliminating fundamental causes when false alarms occur. KEYWORDS: fire indicating equipment, automatically resettable manual operation type, meta-analysis, fluorescence attenuation, false alarms.
