How to choose smoke curtain system?

#### Application Scenario

- **Type and Structure of Building**

   - **High-rise Buildings**: Install in stairwells and elevator lobbies to prevent smoke from spreading quickly.

   - **Underground Structures**: Due to poor ventilation, installing smoke curtains can slow down smoke dispersion and facilitate evacuation.

   - **Large Public Venues**: Such as shopping malls and stations, use them to isolate the fire source and provide safe evacuation routes.

#### System Performance

- **Fire Resistance Rating**

   - Choose systems that meet national standards with high fire resistance ratings to ensure integrity and effectiveness during fires.

- **Smoke Blocking Effectiveness**

   - Preferably select curtains with good sealing performance and excellent smoke blocking effects to effectively prevent smoke spread.

- **Response Speed**

   - The system should be able to rapidly detect smoke and automatically deploy the curtains to control the fire and smoke promptly.

#### Material and Type

- **Material**

   - **Metal Smoke Curtains**: Heat-resistant and corrosion-resistant, suitable for harsh environments like high temperatures and humidity.

   - **Inorganic Fiber Smoke Curtains**: Lightweight and have good thermal insulation but are relatively weaker in strength.

   - **Composite Material Smoke Curtains**: Combine the advantages of multiple materials, offering superior performance but at a higher cost.

- **Type**

   - **Fixed Type**: Simple structure, easy installation, suitable for fixed fire compartments.

   - **Retractable Type**: Can be controlled electrically or manually, allowing flexible adjustment of height and position, ideal for areas requiring frequent adjustments.

#### Control Method

- **Automatic Control System**

   - Integrated with the fire alarm system for automatic detection and activation.

- **Manual Control System**

   - Equipped with manual operation devices for emergency use when the automatic system fails.

- **Remote Monitoring System**

   - Enables remote monitoring and management, enhancing the intelligence level of the system.

#### Brand and Supplier

- **Brand Reputation**

   - Choose reputable brands such as An'an, Nanfei, Tianming Door Industry, etc., to ensure product quality and after-sales service.

- **Supplier Strength**

   - Evaluate the supplier’s R&D capability, production scale, installation services, and after-sales support.

#### Cost and Budget

- **Initial Investment**

   - Consider the initial purchase costs along with installation expenses. High-quality systems may have higher upfront costs but could save money in the long run through better performance and durability.

- **Maintenance Costs**

   - Factor in ongoing maintenance and potential repair costs. Reliable suppliers often offer comprehensive after-sales support and maintenance plans.
