Automatic fire alarm systems can be used to notify people to evacuate in the event of a fire or other emergency, to summon emergency forces aid.
In addition, to prepare the structure and associated systems to control the spread of fire and smoke.
There are many types of fire alarm systems each suited to different building types and applications. A fire alarm system can vary dramatically in both price and complexity, from a single panel with a detector and sounder in a small commercial property to an addressable fire alarm system in a multi-occupancy building. Systems have to protect both buildings and occupants.
Fire alarm systems typically consist of five (5) elements.

• Fire detectors: Detects either smoke or heat detectors. Most of the time, a combination of both provides the best protection.
• Pull Station/Signal boxes: It is a manual process, by pulling a manual alarm can lead to a much faster response than waiting for a detector to react.
• Control panel: Ties all the elements of the system together, provides status reports on each zone. The control panel is also connect via phone line to a monitoring service
• Bells and lights: Strobe lights and loud bells are for getting people's attention and alert people to evacuate the building.
• Backup battery: Fire can easily destroy the main power supply – a backup battery ensures that the system will always be available and respond.
