The first step to stop a fire is to correctly identify the incident, raise the alarm to the occupants, and notify the emergency answer specialists. This is very often the function of the fire detection and alarm system. There are several types of systems and options available, always depending on the specific characteristics of the space to be protected.

Before we try to understand the fire detection systems and automatic fire sprinklers, it is advisable to have a common knowledge of the development and behavior of a fire.

Basically, a fire is a chemical reaction where a material based on carbon (combustible), which mixes with oxygen (normally as part or component of the air), gets hot to a point where inflammable vapors are produced. These vapors can come in contact with something which is hot enough to cause an ignition of the vapors thus we get a fire. In simpler terms, something that can burn touches something that is hot and a fire is produced.

A key item in the protection against fires, is to identify a fire emergency in an opportune time, in order to alert the building occupants and the emergency against fires teams. This is basically the role of a fire detection and alarm system. Depending on the foreseen place of a possible fire, the type of construction, i.e. building, and its use, the amount and type of occupants, the level of service and the mission, these systems can provide several principal functions.

The main function though, is to provide a mean of identifying a developing fire through a manual or automatic method, and in second place, alert the building occupants of a fire condition and the necessity of evacuation. Another typical function, is the transmission of an alarm signal to the fire department or other emergency entity. Other functions can be to shut off electric equipment, air or other special process operations devices which can be used to automatic suppress systems.
