How does a fire protection system work?
Automatic Suppression Systems
Wet pipe automatic sprinkler systems commonly have water flow detectors.
As water starts to flow in the sprinkler piping, it causes a vane to swing into an alarm position; this sends an alarm to the fire alarm panel.
Dry pipe sprinkler systems may have pressure sensors for the same reason..
How is fire controlled?
The most common method to control a Class-A fire is to remove heat by spraying the burning solid fuels with water.
Another control method would be to reduce the oxygen content in the immediate vicinity of the fire (i.e., "smother" the fire), such as by the introduction of an inert gas such as carbon dioxide..
What are the fire control systems in buildings?
Basic Components of a Fire Alarm System
These are the circuits which connect initiating devices such as smoke detectors, heat detectors, manual pull stations, and water flow alarms.
Additionally, many system monitor devices important to the overall fire safety of the building also tie in to initiating circuits..
What does fire protection system do?
The aim of a fire protection system is to protect a building's occupants and minimise the damage associated with fire.
Overall, the goal is to provide the widest possible window for a safe evacuation, whilst also reducing potential repair costs.
Fire protection systems can be categorised as either active or passive..
What is an active fire control system?
Active Fire Protection Systems.
Active fire protection refers to systems that involve a triggered response to a fire.
Active systems are initiated by the flame and the response may be manual (for example, a hand operated fire extinguisher qualifies as an active response) or programmed (for example, a sprinkler system)..
What is an automatic fire control system?
Automatic fire suppression systems control and extinguish fires without human intervention.
Examples of automatic systems include fire sprinkler system, gaseous fire suppression, and condensed aerosol fire suppression..

Fire protection systems can be categorised as either active or passive..
- An active fire protection system means that action of some kind is taking place.
This action can be manual, meaning that a person or persons may engage in it, or it may be automatic, deploying once fire, smoke or heat is detected. - Gas suppression systems store fire-suppressing liquids, which are pressurised with nitrogen.
These liquids contain a chemical agent called FM200, which is quickly released to immediately suppress flames. - The five common methods of extinguishing fires are cooling with water for Class A fires, smothering with a chemical for Class B fires, starving (cutting off the supply of oxygen) for class C fires, breaking the chain reaction of fire for Class D fires, and Chemical fire extinguishers for Class K fires.
