What is a fire sprinkler system?
Fire sprinkler systems are an active fire protection method that uses a water supply system to detect and extinguish fires in their early stages. The system has sprinkler heads that work independently, activated by heat, and throw water onto the fire. These systems are widely used worldwide, with over 40 million heads fitted annually, but they are not always designed to protect buildings.
1. How does a fire sprinkler system work?
A fire sprinkler system works by providing adequate pressure and flow to a water distribution piping system and connecting sprinkler heads to extinguish fires in their early stages. Each head is activated by heat, causing a glass bulb to shatter.

- What is a Pre-action fire sprinkler system
The water supply system, connected to a reliable source like a tank, stores water under pressure in pipes. When a fire breaks out, the heat expands the sprinkler head, releasing water and spraying it onto the fire.
Cheap sprinkler systems are now available for homes and small buildings. They were first used in factories and big commercial buildings। Though they were designed to save lives, they control fires in 96% of cases।
2: What is the difference between wet and dry sprinkler systems?
Fire sprinkler systems are divided into wet and dry. Wet systems use pressurized water, while dry systems use pressurized air or nitrogen। Although wet systems are easy, affordable, and reliable, they are not appropriate for buildings that have temperatures below freezing। However, dry systems are perfect for freezing structures like parking garages and walk-in refrigerators because they use pressurized air or nitrogen to hold water at a riser।
3: What is a pre-action sprinkler system?
Pre-action sprinkler systems are fire suppression systems designed to reduce false alarms and water damage in establishments. It activates the system by using water and air pressure, holding water from the piping through an electrically operated pre-action valve. Flame, heat, and smoke detections independently control the system. Sprinkler discharge can only start after two distinct events: recognizing a developing fire, opening the pre-action valve, and releasing separate sprinkler heads.
4: What are the benefits of a pre-action sprinkler system?
Pre-action sprinkler systems are a type of fire suppression system designed to reduce the risk of false alarms and water damage in facilities 123। They activate the sprinkler system and suppress a fire 2 by using a combination of water and air pressure। In contrast to a dry pipe system, the system does not typically contain water within pipes 1। But the difference is
A pre-action valve, an electrically operated valve, keeps water out of the pipe.
Flame, heat, or smoke detection controls valve operation. Sprinkler discharge activation requires two distinct events. First, a developing fire must be identified by the detection system, and then the pre-action valve must be opened. Because of this, water can flow into the system pipes, creating a successful wet pipe sprinkler system. Secondly, each sprinkler head must be removed so that water can flow onto fire Occasionally, a pre-action fire sprinkler system may be installed using a double interlock, where pressurized air or nitrogen is added to the system piping.
This feature has two purposes: first, to check pipes for leaks and second, to keep water out of system pipes in the event of inadvertent detector operation.
4.1. The benefits of pre-action sprinkler systems include the following:
Environments that are water-sensitive: Pre-action sprinkler systems are ideal for water-sensitive areas like labs, archival vaults, and data centers।
Preventing unintentional discharge: Water is discharged in two ways, guaranteeing that no water is unintentionally discharged 1।
Water and fire protection: Pre-action sprinkler systems work well in cold areas because the pipes will not freeze because water is not held within the pipes.
