What are the different types of automatic fire protection?

automatic fire protection systems work on slowing the spread of fire without the need for manual assistance or activation. As soon as the alarm goes out, fire or smoke goes out, the system will automatically burn fire or slow down its spread. These automatic fire protection systems help reduce property damage and often allow more people to leave the building, reducing the number of injuries or death. While most fire suppression systems are found in commercial structures, some building regulations may require sprinklers or other protective devices in residences.

Wet sprayers are the most common type of automatic fire protection system. They consist of pipes filled with water that pass through the ceiling of the building, while at the designated intervals there is a spray head in the ceiling. Each head contains a bulb filled with a liquid that bursts when exposed to high temperatures, allowing water to flow from the head. Unlike the popular, during the afterThe heat is activated only by heads exposed to high temperatures, which helps to reduce damage to property from the water.

In the sinking system, all heads cooperate on fire. This type of automatic fire protection system consists of pipes filled with water activated either by smoke alarms or temperature gauges in the building. During the fire, all the heads release water to quickly and efficiently throw away the flames. Flood systems are most common in high -risk devices such as chemical or industrial plants.

Some applications require dry pipes or preliminary action instead. In the preliminary system, the pipes are filled with air rather than water. The system requires two separate signals before release of water from each head. Initial smoke alarm or hand inputs will alert the system to fill the pipes with water. Once each head is exposed to a sufficiently high temperatureLY to allow water from the head.

Museums and libraries often rely on a preliminary system or on the chemical technique of fire suppression. In chemical systems, the heads of sprayers release dry chemicals or gas to suffocate fire. This limits damage to the water of sensitive or irreplaceable objects such as images or books. This type of dry chemical spraying system often includes halon gas, although Halon is generally replaced by more environmentally friendly products. Dry automatic fire protection systems may pose a health risk to residents in some applications and usually occur in unoccupied parts of the building.
