CHAPTER ONE

 

1.0            INTRODUCTION

1.1     BACKGROUND OF PROBLEM

          Fire detection system are safety system. They monitor rooms and buildings continuously for indication of fire outbreak and give alarm directly if one occurs.

          Both the British Factory Acts 1961 and the officers shops and railway premises Acts 1963 stiputed minimum requirements in the case of fire that there shall be clear and audible warning throughout the building. Also, an earlier statutory requirement (section 36[7] of the factories Acts 1937) states that in any factory, hospitals, market places, homes etc. Where more than 20 persons are employed that place should be effective provision for giving warning signal in case of fire outbreak and that it shall be clearly audible throughout the building.

 

 

 

1.2            STRUCTURE OF THE PROBLEM

            The alarm is given locally (visually and audibly) in order to mobilize internal auxiliary personal e.g the works fire brigade) and inform them as to the seat of the fire. A control center performs the organization of the alarm, that is, it makes available operational aids for the fire fighting measures and automatically bring the fire protection equipment into operation. Fire detection system must be tailored to the geographical and operational conditions in each
