SUBMITTED TO THE INDUSTRIAL TRAINING COORDINATING CENTRE (ITCC) IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE COMPLETION OF THE 300 LEVEL INDUSTRIAL TRAINING PROGRAMME NOVEMBER-JANUARY 2010. Adeniran Obafemi O. Department of Electrical/ Electronics Engineering University of Ibadan, Ibadan, Nigeria. 20th of february, 2010. The Director,Student Industrial Work Experience Scheme, Industrial Training Coordinating Centre, University of Ibadan, Ibadan. Dear Sir,SUBMISSION LETTER FOR TIT 399 REPORT WORKHaving completed the eight weeks training programme required by the Student Industrial Work Experience Scheme (SIWES), which started on the 16th of November, 2010 and ended on the 15th of January, 2010, I hereby write to inform you that the report work was compiled and completed by me.

I therefore submit the report work as partial fulfillment of the requirements for the student industrial work experience scheme of the University of Ibadan. Yours sincerely, Adeniran Obafemi . 134196.CERTIFICATIONI, Adeniran Obafemi Olubunmi with matriculation number 134196 hereby declare that I undergo two full months of Industrial Training Programme at Aitek Networks Systems Limited, Ikeja, Lagos and that this report is written by me to the best of the practical knowledge I gained during the course of the training programme. —————————————- 134196 ABSTRACTAitek Networks Systems Limited is one of the very few indigeneous companies that is well established in the aspect of electronics engineering referred to as Surveillance or better still Extra Low Voltage.

The company is staffed with hardworking, resilient, intelligent and hospitable personnels . The sale and installation of various security devices are carried out by experts at Aitek Network Systems Limited. Devices like the smoke detectors, satellite televisions, cctv, camera, motion detectors, fire alarm systems, network systems to mention a few are sold and installed by capable engineers and technicians. However, there is the administrative section consisting of the secretary, receptionist, cleaners, drivers, personal assistant and the managing director.

All other staffs are transported to the site to ensure services are procured to customers. INTRODUCTIONA great deal of knowledge and tremendous skills related to electrical/electronics engineering was imbibed on me during the few weeks of rigorous training I went through at Aitek Networks Systems Limited in Lagos. An enormous amount of physical and intellectual strength is required to survive on site at the engineering firm. Almost all the installation processes involves a great deal of cabling that is running of cable through trunkings, pvc pipes or ebonite tubes. Also, cables are run through manholes from metal boxes or adaptable boxes.

The basic tools often used are the fishing tapes, draw ropes, drillings machines, screws, screwdrivers, mallet, chisel, cables, connectors, masking tapes, multimeter, cutter to mention a few. As we all know, our society is in jeopardy as far as security is concerned, this calls for the installation of security systems by experts. Systems such as the fire alarm systems, cameras, motion detectors, smoke and heat detectors etc serve to reduce if not to completely eliminate impending hazards This report treats in details some other systems such as the network system (LAN) and so on.ACKNOWLEDGEMENTI thank God Almighty for his mercy and grace that kept me all through my industrial training period. I am greatly indebted to my parents, Mr and Mrs Adeniran for their financial and moral support during the course of the programme and my uncle, Mr Omofoyewa for his hospitality and fatherly care towards ensuring that my industrial training was a worthwhile and fulfilling one. I also want to thank everyone that contributed to the success of my industrial training; my industrial supervisors, my colleagues, co-workers and my relatives.TABLE OF CONTENTSTITLE PAGE…………………………………………………………………………SUBMISSION LETTER……………………………………………………………………i CERTIFICATION…………………………………………………………………………………………………………………….

72 CHAPTER ONE FIRE ALARM SYSTEM AND OPERATIONS An automatic fire alarm system is an active fire protection system designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion.In general, a fire alarm system is either classified as automatic, manually activated, or both. The basic modern system consists of a dependable primary power supply, a secondary or backup power supply, any number of “initiating devices” and “notification appliances. ” Automatic fire alarm systems can be used to notify people of the need to evacuate in the event of a fire or other emergency, to summon emergency forces aid, and to prepare the structure and associated systems to control the spread of fire and smoke.However, the use of fire alarm system in buildings and campuses in Nigeria is not encouraging at all. FUNDAMENTAL COMPONENTS THAT MAKE UP THE FIRE ALARM SYSTEM • Fire alarm control unit (panel): A fire alarm control panel is the central control device that receives information from input devices such as smoke detectors, heat detectors, manual call points, etc. The panel then processes the information to trigger output devices which are usually bells, horns, or strobes.

Panels usually have a number of loops within the range of two to 20 loops.At the present time, four or six loop panels are the most common. Each loop can have a number of devices connected to it. Each device has its own address, and so the panel knows the state of each individual device connected to it. There are three types of panels: coded panels, conventional panels, and addressable panels. A fire alarm control panel • Primary Power supply: Commonly the non-switched 220/240 Volt Alternating Current source supplied from a commercial power utility. In non-residential applications, a branch circuit dedicated to the fire alarm system and its constituents.

Dedicated branch circuits” should not be confused with “Individual branch circuits” which supply energy to a single appliance. • Secondary (backup) Power supplies: This component commonly sealed, lead-acid storage batteries or other emergency sources including generators, is used to supply energy in the event of a primary power failure. • Initiating Devices: This component acts as input to the fire alarm control unit and are either manually or automatically activated. Examples of initiating devices are manual call point/break glass, smoke detector, heat detector, carbon mono-oxide detector, etc. manual call point/break glass
