The first priority in a fire situation is evacuation of people in the building. It is very important to execute evacuation gradually. People who are nearest to fire should be evacuated at first. Otherwise, there will be confluence in the escape route. So people should be warned respectively according to how close they are to the fire incident. For example, if a fire incident happens at the fourth floor of a high rise building, people at the fourth, fifth and third floor should be warned first by sounders and beacons of the fire alarm system.
For safe evacuation in case of a fire, people should be notified and guided effectively. Public address (PA) and voice evacuation (EVAC) systems should be integrated to fire alarm systems for effective notification in case of fire. Fire alarm systems should give information to PA and EVAC systems about the location of fire. Then people in the building should be notified by these systems according to the information supplied by fire alarm systems. Communication of these systems is the most crucial point in case of emergency.
In order to execute evacuation of people safely, poisonous smokein the building should be removed. Fire smoke is highly poisonous and it may cause serious injuries or casualties. For this reason, smoke dampers, HVAC systems, fans and other smoke control systems should be integrated to fire alarm systems. In case of a fire, fire alarm systems should manage smoke control systems for removal of smoke from the building.
To conclude, electronic and mechanical systems in the buildings should be integrated to fire alarm systems for safety of life and property.
