Use of Fire Plume Theory in the Design and Analysis of Fire Detector and Sprinkler Response

Schifiliti, Robert P. 18 January 2000 (has links)
This thesis demonstrates how the response of fire detection and automatic sprinkler systems can be designed or analyzed. The intended audience is engineers involved in the design and analysis of fire detection and suppression systems. The material presented may also be of interest to engineers and researchers involved in related fields. National Bureau of Standards furniture calorimeter test data is compared to heat release rates predicted by a power-law fire growth model. A model for calculating fire gas temperatures and velocities along a ceiling, resulting from power-law fires is reviewed. Numerical and analytical solutions to the model are outlined and discussed. Computer programs are included to design and analyze the response of detectors and sprinklers. A program is also included to generate tables which can be used for design and analysis, in lieu of a computer. Examples show how fire protection engineers can use the techniques presented. The examples show how systems can be designed to meet specific goals. They also show how to analyze a system to determine if its response meets established goals. The examples demonstrate how detector response is sensitive to the detector's environment and physical characteristics.

Příprava kampaně k propagaci zařízení autonomní detekce a signalizace v rámci preventivně výchovné činnosti na úseku požární ochrany / The preparation of campaign to promote an equipement of antonomous detection and signals in the framework of the preventive educational activities in the field of the fire protection

JARMAROVÁ, Lenka January 2013 (has links)
The preparation of campaign promoting autonomous detection and signaling devices within activities of preventive education in section of fire protection We can come across fires of buildings designed for living every day, therefore is very important to try to prevent them. The most accessible way is the installation of autonomous detection and signaling devices, which is currently obligatory to all newly designed and built houses. These devices detect emerging fire, subsequently inform about possible threat and at the same time they allow enough time for the population rescue. To achieve the main aims of thesis, it was needed to study specialized literature and write theoretical part which explains basic concepts connected to the topic, defines the dangers in the place of fire, followed by classification of toxic substances which are released during the fire and finally describes autonomous detection and signaling devices. The integral part contains the graphic layouts focused on the comparison of statistical data from 2001 till 2011, mostly tracking fires and number of killed and injured people during the household fires, which is compared to the number of killed and injured people and fires in general. There was made questionnaire for 50 public respondents from the city Zábřeh after completing the theoretical part. These respondents were chosen on purpose in cooperation with the fire station Zábřeh, which is part of Fire Rescue Service of Olomouc district. We defined hypothesis: The knowledge of Zábřeh population about own life and property protection against the fire are insufficient. The hypothesis was defined using descriptive and mathematical statistics. However, our hypothesis wasn´t confirmed so we can consider awareness of Zábřeh population to be sufficient but not excellent. Therefore, there is still need to increase their legal responsibility. The practical part further includes the analysis of questionnaire answers, which is aimed to evaluate the accuracy of answered questions. Last but not least, the thesis presents the set of promotional campaigns which are ordered by the ability to properly effect on the population via web pages, daily press, TV broadcast or printed materials. The most wanted way would be TV campaign, which is unfortunately expensive and time-consuming; therefore, it seems to be the best option to create web pages or printed material aimed for general public. The both promotional campaigns should be provided by Ministry of the Interior - general directorate of Fire Rescue Service of Czech Republic.

Komplexní zabezpečení objektů / Project of comprehensive security objects

Michálek, Libor January 2011 (has links)
In my thesis I go about principles and methods of security systems, then I go about analysis of avalaible types of security systems (EPS, EZS and CCTV). I have written about their possibile use in design security building. I have described levels of project documentation and its different parts including process service of production a project documentation for security system. I used all knowledges in the end of my thesis, when I designed and integrated security system for a special building.
