The Futian special-grade inorganic double-track double-curtain fire shutter is lightweight with excellent insulation. Back-face temperatures stay low, fire resistance performance is solid, and it works well for large spans and irregularly shaped fire compartments.
Technical Parameters
- Back-face average temperature rise: less than 79.6°C
- Single point temperature rise: less than 113.3°C
- Fire resistance rating: 4.0 hours or more
- Opening and closing speed: 2 to 9 meters per minute
- Smoke leakage: no more than 0.2 m³/m²/min
- Back-face radiant heat intensity: 0.61 W/cm²
- Wind pressure resistance: at 784.5 Pa, slat center deflection is 45mm
- Motor power: 0.25 to 1.5 kW
- Power supply: AC 380V, 50Hz; Control power: DC 12 to 24V
Control Methods
The electrical control system responds to smoke and heat detector signals to close, or links with the fire control center. Manual control is available during normal operation. During a fire alarm, the door automatically descends to a mid-point, pauses, then completes the descent. During a fire, pressing any button reverses the door upward. The reverse height and mid-point dwell time are adjustable.
