A Fire Sprinkler Installation is one of the most reliable and effective active fire protection methods available today. Unlike other systems that require human intervention or manual activation, a sprinkler system works automatically, 24 hours a day, 7 days a week, to detect and suppress a fire in its early stages. Its presence in a building drastically reduces the risk of property damage, business interruption, and most importantly, loss of life. Sefirepro has years of experience in designing and implementing sprinkler systems that comply with the highest safety standards. This article will explain in detail how they work, the different types of sprinkler systems, and why professional installation is a must.
Many people mistakenly believe that all sprinkler heads will activate simultaneously during a fire, as often depicted in movies. In reality, modern sprinkler systems are much smarter. Only the sprinkler head closest to the heat source of the fire will activate. This ensures that water is sprayed only on the area that truly needs it, minimizing water damage and maximizing suppression effectiveness.
How Does a Fire Sprinkler System Work?
Understanding the basic mechanism of a fire sprinkler installation will help you appreciate its effectiveness. Each sprinkler head in the system is equipped with a thermosensitive element, usually a small glass bulb containing a glycerin-based liquid or a fusible metal link.
- Heat Detection: When a fire occurs, the hot air rises to the ceiling.
- Automatic Activation: When the temperature around a sprinkler head reaches its activation point (usually between 57°C and 77°C), the liquid in the glass bulb expands and shatters the glass, or the metal link melts.
- Water Release: The breaking of this thermosensitive element opens a plug valve in the sprinkler head. Pressurized water that is on standby inside the pipes is immediately sprayed out.
- Area Wetting: Water is sprayed evenly downward in a specific pattern by a deflector, directly wetting the fire area, cooling the burning material, and suppressing the fire before it can spread widely.
This system is connected to the building’s fire alarm system, which will sound simultaneously to notify occupants to evacuate immediately.
Types of Systems in a Fire Sprinkler Installation
There are several types of sprinkler systems, and the right choice depends heavily on the environmental conditions where the system will be installed. Sefirepro can help you determine the most suitable type.
1. Wet Pipe System
This is the most common, reliable, and economical type of sprinkler system.
- How it Works: The entire piping network is filled with pressurized water at all times. As soon as one sprinkler head activates, water is sprayed out immediately.
- Applications: Ideal for most buildings where the temperature always remains above freezing (4°C), such as offices, hotels, hospitals, and shopping centers.
- Advantages: Fast response, simpler maintenance, and lower installation costs.
2. Dry Pipe System
This system is designed specifically for areas where temperatures can drop below freezing.
- How it Works: The piping network is filled with pressurized air or nitrogen, not water. Water is held back by a dry pipe valve in a heated area. When a sprinkler head activates, the air pressure in the pipes drops dramatically, causing the valve to open and allowing water to flow into the pipes to be sprayed.
- Applications: Unheated parking areas, cold storage facilities, and loading docks.
- Disadvantages: Slightly slower response compared to a wet pipe system and requires more complex maintenance.
3. Pre-Action System
This system is a combination of a sprinkler system and an independent fire detection system. It is designed for areas with assets that are highly sensitive to water.
- How it Works: This system requires two triggers before water is released. First, the fire detection system (like a smoke detector) must activate. This will open the pre-action valve, allowing water to fill the pipes. However, water will not be discharged until the thermosensitive element on a sprinkler head breaks due to heat.
- Applications: Museums, data centers, libraries, and important archival rooms.
4. Deluge System
This system is used for the protection of high-hazard areas where fire can spread very rapidly.
- How it Works: All sprinkler heads in this system are open (they do not have a thermosensitive element). The pipes are dry. When the connected fire detection system activates, a deluge valve opens, and water is discharged from all sprinkler heads simultaneously, flooding the entire protected area.
- Applications: Chemical plants, aircraft hangars, and facilities storing flammable materials.
The Importance of Professional Design and Installation
An effective fire sprinkler installation requires more than just installing pipes and sprinkler heads. The process involves complex hydraulic calculations, selecting the right components, and adhering to strict safety standards like SNI or NFPA 13.
Errors in design or installation can lead to:
- Inadequate water pressure.
- Uneven spray coverage (creating blind spots).
- System failure when needed.
- Violation of building regulations.
