**What is a Large Space?**
A large space refers to areas with a ceiling height greater than 8 meters in civil and industrial buildings, and more than 12 meters in warehouse buildings. These spaces are typically found in public or commercial facilities where conventional fire suppression systems may not be effective due to the height and scale of the area.
**Where Are Large Space Intelligent Fire Suppression Devices Suitable?**
These devices are ideal for locations that have high ceilings and large open areas. Examples include:
1. Exhibition Centers, Halls, and Trade Fairs – Large foyers, exhibition halls, and atriums.
2. Large Commercial Halls, Malls, and Markets – Open halls, atriums, and pedestrian streets.
3. Office Buildings and Business Centers – Conference rooms, atriums, and large meeting spaces.
4. Hospitals and Rehabilitation Facilities – Atriums, waiting areas, and common spaces.
5. Airports, Train Stations, and Docks – Passenger waiting areas, ticket halls, and terminal spaces.
6. Cultural Buildings – Libraries, museums, art galleries, and cultural centers.
7. Performing Arts Venues – Theaters, concert halls, and auditoriums.
8. Sports Facilities – Gymnasiums, training halls, and sports arenas.
9. Industrial and Storage Facilities – Warehouses and storage areas for Class A materials.
**What is a Large Space Intelligent Fire Suppression Device?**
This system combines automatic scanning and water-spraying technology to detect and extinguish fires quickly. It includes several types, such as ceiling-mounted, mid-suspended (gun-type), quick-spray, and centrifugal sprinklers. Each device is equipped with sensors and a microprocessor to identify flames and activate water spray. The system can scan, locate, and target the fire point accurately, ensuring rapid and efficient suppression.
**How Does Automatic Scanning and Positioning Work?**
Once activated, the device scans horizontally and vertically to locate the fire source. Upon confirmation, it aligns itself to the exact location and sprays water in a full column. The solenoid valve opens, triggering alarms and initiating the fire suppression process. After the fire is out, the system automatically stops spraying and returns to monitoring mode. If a second fire occurs, the process repeats.
**How Does the Automatic Sprinkler System Work?**
The system continuously monitors the environment using ultraviolet and infrared sensors. When a fire is detected, it activates the solenoid valve, sends an alarm signal, and releases a fine water mist across the protected area. This mist effectively penetrates hot air layers and suppresses the fire. Once the fire is gone, the system resets and continues monitoring.
**Key Features of Large Space Intelligent Fire Suppression Systems**
- **Real-Time Response:** Detects and responds to fires within 20 seconds.
- **Effective Fire Suppression:** Uses high-pressure water jets to cover the entire fire area.
- **Reliability:** Combines multiple sensor inputs for accurate fire detection.
- **Self-Inspection:** Built-in diagnostics ensure the system is always operational.
- **Full-Space Protection:** Covers 360° horizontally and 180° vertically, providing comprehensive coverage.
- **Repeatable Extinguishing:** Can re-spray if a fire reignites.
**Main Product Parameters**
- **Ceiling-Mounted Units:** Rotate 360° horizontally and 110° vertically. Installation height: 2–8 meters. Working pressure: 0.4–0.6 MPa.
- **Mid-Suspended Units:** Cover 360° horizontally and 180° vertically. Installation height: 6–30 meters.
- **Centrifugal Units:** Spray water evenly without rotation. Installation height: 8–30 meters.
- **Quick-Spray Units:** Ideal for high-ceiling areas. Installation height: 8–20 meters.
**System Components**
The system includes fire extinguishing devices, solenoid valves, junction boxes, regional valves, water distribution networks, manual gate valves, pressure gauges, fire pumps, and control panels. It is flexible, easy to install, and can integrate with existing fire alarm systems.
**Advantages of Automatic Scanning and Positioning Systems**
1. Simple and efficient system design.
2. Reduces construction time and material costs.
3. Transforms passive fire protection into active suppression.
4. Cost-effective and easy to maintain.
5. Enables early fire detection and fast response.
6. Accurately targets the fire source for optimal water use.
7. Solves challenges in suppressing fires in high spaces over 12 meters.
