DESIGN AND CONSTRUCTION OF FIRE ALARM SYSTEM IN A THW STOREYED BUILDING

CHAPTER ONE

1.0            INTRODUCTION

1.1     BACKGROUND OF PROBLEM

Fire detection systems are a type of safety system. They continuously monitor rooms and buildings for signs of a fire outbreak and immediately notify authorities if one occurs.

Both the British Factory Acts of 1961 and the Officers Shops and Railway Premises Acts of 1963 stipulated that in the event of a fire, there must be clear and audible warning throughout the building. Furthermore, an earlier statutory requirement (section 36[7] of the factories Acts 1937) states that in any factory, hospital, market place, home, or other place where more than 20 people are employed, there should be effective provision for providing a warning signal in the event of a fire outbreak, and that it should be clearly audible throughout the building.

1.2            STRUCTURE OF THE PROBLEM

The alarm is issued locally (visually and audibly) to mobilize internal auxiliary personnel (such as the works fire brigade) and inform them of the location of the fire. A control center organizes the alarm, that is, it makes operational aids for fire fighting measures available and automatically activates the fire protection equipment.
