The requirements to install a fire alarm system are based on several factors that are found in current buildings (as well as buildings being built). These factors include the type of building classification, the number of people that can be in the building (based on maximum number of people), and size of the building.
A fire alarm system is considered a life safety system. It is designed to operate automatically when either a manual pull station is activated or when smoke is detected by a smoke detector. Upon activation, it will notify the building occupants by flashing lights and a loud sound to evacuate the building.
A fire alarm system is also one of the two most important fire protection systems that can be installed in a building to protect the contents, inventories, stock, merchandise, tools and equipment, and the lives of those people who work in the building and those who visit the building.
