Special Type Inorganic Fire Curtain (Vertical Type)

1. System Overview

The Special Type Inorganic Fire Curtain (Vertical Type) is a high-performance fire compartmentation assembly constructed with an inorganic, noncombustible curtain that provides an extended fire-resistance rating and excellent thermal insulation. The curtain is typically installed above an opening and, upon fire conditions, automatically deploys vertically to form a high-grade fire and smoke barrier between fire compartments.

Compared with conventional steel fire shutters, the special-type inorganic fire curtain offers superior fire integrity, insulation performance, and high-temperature stability, maintaining structural stability during prolonged fire exposure. It is widely adopted as a critical fire separation solution in high-grade public buildings and mission-critical facilities.

2. Key Advantages

2.1 Inorganic, Noncombustible Materials – Superior Fire Performance

The curtain is fabricated from inorganic fibers or inorganic composite materials that are noncombustible and non-melting, ensuring stable fire performance under high-temperature fire conditions.

2.2 Special Type Fire Resistance with Excellent Thermal Insulation

Meets special type fire-resistance requirements, effectively limiting flame spread, radiant heat transfer, and high-temperature transmission to adjacent compartments, significantly reducing unexposed-side temperature rise.

2.3 Vertical Deployment – Reliable Fire Compartmentation

The vertical rolling deployment provides a well-defined load path and, when fully closed, forms a continuous and complete fire barrier suitable for standard and large openings.

2.4 Stable Smoke Control Performance

A dense curtain structure combined with guide rail and sealing design minimizes smoke leakage, meeting smoke compartmentation requirements in building fire protection design.

2.5 Automatic Interlock with Safe Manual Override

The system can be interlocked with the fire alarm system to deploy automatically during a fire, and is also equipped with manual control and emergency operation to ensure reliable performance under all conditions.

3. Operating Principle

1. Under normal conditions, the special type inorganic fire curtain remains rolled up on the headbox/roller assembly above the opening.

2. Upon fire detection, the fire alarm control unit (FACU) sends an activation signal to the curtain control system.

3. The drive system actuates, and the curtain deploys smoothly downward along the guide rails.

4. When fully deployed, the curtain forms a high fire-resistance, high-insulation fire and smoke barrier between compartments.

5. After the fire event and upon confirmation of safety, the system may be manually reset.
