This paper discussed on design and development of fire warning system using automated remote messaging method. This device enables to alert the owner whenever fire occur that need rapid attention towards the building. This is maybe due to carelessness of user or gas leakage. Fire warning system is an existing project but it will be enhanced. This project discussed the design and implementation of a fire alarm system using the microcontroller which controlled the entire system. This system comprised of smoke detector that linked to PIC and GSM Modem. When smoke detected, the fire alarm will triggered and send a signal to the PIC. The PIC will process the data and transmit the signal to the GSM modem. The GSM modem will send message to alert the building owner. The owner can make further action by informing the nearest fire department. This module is applied for transferring of GSM SMS message to the owner mobile number. The devices can be the early and fast prevention system for building owner.

Introduction. Fire alarm system controllers are the main technical aids that serve as the backbone of a fire alarm system (a unit) at a facility. They consolidate fire alarm messages, coming from fire detectors, analyze, process, and deliver them to the user and display them in the pre-set format. The technical capacity of fire alarm system controllers is constantly improving in line with the technical progress and tightening fire safety requirements.Aims and purposes. The purpose of the article is to analyze the state of and trends in the development of fire alarm system controllers, that improve the fire safety of protected facilities. The task encompasses the retrospective review of principal tactical and technical characteristics of fire alarm devices for the period starting from the early 1950s to the present time in Russia, as well as the statistical analysis of the pace of their supply on the market of automatic fire fighting systems.Methods. Methods of system analysis and mathematical statistics were used.Results and discussion. The main stages of development of instruments for fire alarm systems that are reflective of the technical progress, primarily in the field of radio electronics, as well as the socio-economic transformations in Russia are specified. The article presents the results of statistical studies, carried out by the co-authors at different times and characterizing a change in the Russian market based on the comparative data on domestic and foreign alarm systems. The main trends in the development of the product mix and technical specifications of devices during the analyzed period are identified. The co-authors focus on the generalized layout of a blockmodular apparatus of a fire alarm system controller and determine the requirements for communication between functional modules to ensure the reliable operation of a fire alarm system.Conclusions. The main trends in the development of fire alarm system controllers, designated for fire alarm systems, focus on the application of new communication technologies and microelectronic devices that solve comprehensive safety problems with regard for the top-priority requirements of fire safety. The pace of improvement of tactical technological characteristics of devices is reflective of the state of and trends in the development of automatic fire fighting systems in Russia.

Introduction. Rationale of the topic of this article is the need to improve the effectiveness of fire detection. One of the modern solutions to this problem is the use of video technology. The article is aimed at developing a method to assess the effectiveness of video surveillance in the fire protection system on the basis of the formed mathematical model.Methods of research. The fire risks theory is used for formation of mathematical model. The potential fire detection risk is introduced as a quantitative measure of the possibility of undetected fire occurrence at the protected facility, development and implementation of its consequences for people and material valuables. It is calculated as the product of the maximum probability of fire by the probability of its non-detection by the technical means and alarm systems used. The efficiency of video surveillance use in the fire protection system is determined on the basis of compliance of the complex risk index of fire non-detection with the permissible value.Research results. The possibilities of increasing the efficiency of fire detection through the use of video technology are considered. Reducing the fire detection risk can be achieved by using video channel fire detectors that reduce the time it takes to reliably detect a fire. The probability of reliable detection is an important parameter of the detector during its operation in the fire alarm system and characterizes the degree of performance of its main function. The main ways to improve the efficiency of fire detection are the improvement of fire detectors with video channel, the joint use of fire video detectors and other detection devices, such as automatic multi-criteria detectors, thermal imaging сamera, as well as the use of photo and video in centralized surveillance systems.Conclusions. The offered method of estimation of efficiency of application of video surveillance in fire protection systems can be used for a substantiation of parameters of technical means (systems) of the fire alarm system and passive fire-fighting measures established on the facility.
