SMOKE & FIRE CURTAIN SOLUTIONS – QUICK SPEC SHEET
1. What they do
• Fire curtain: 1–4 h fire resistance; blocks flames & hot gases.
• Smoke curtain: 30–120 min smoke-tight; channels toxic smoke toward extraction.
• Combined curtain: single barrier certified for both fire and smoke (EN 12101-1 / BS 8524 / UL 10D).
2. Typical makeup
– Curtain fabric: e-glass + stainless thread + silicone or PU coating, 400–900 g/m².
– Roller box: 0.8–1.2 mm galvanized or stainless steel, 200–350 mm Ø.
– Side guides: 1.5 mm steel or aluminium with intumescent smoke-seal brush.
– Drive: 24 V DC tubular motor with integrated brake; battery back-up 30–90 min.
– Release: fusible link 68 °C, or signal from fire panel (FSA / FSC), 0.2 m/s descent.
3. Sizes (single span)
Width up to 8 m (smoke) or 6 m (fire); height up to 10 m without intermediate support.
Larger openings → multiple curtains overlapped 100 mm or side-by-side with 50 mm gap sealed.
4. Controls & interface
• Normally held retracted by electromagnetic brake; failsafe gravity closure.
• Feedback: open/closed limit switches + curtain-in-position volt-free contacts.
• Integrates with any addressable fire alarm; supports BACnet/Modbus gateway if BMS required.
5. Certification snapshot
– Fire integrity: EW 60 / EI 120 (EN 13501-2) or UL 10D 2 h.
– Smoke leakage: S 600 (–20 Pa) ≤ 5 m³/h·m (EN 12101-1).
– Cyclic durability: ≥ 2 000 cycles (EN 14600).
6. Where used
• Atrium separation, escalator surrounds, lift-door protection, open-plan office compartments, corridor sub-division, kitchen-to-public boundary, museum voids, airport piers.
7. Installation notes
• Box recessed in ceiling or surface-mounted; allow 150 mm clearance for maintenance.
• Minimum 500 mm free space above box for fabric rewind.
• Power: 230 V AC supply converted to 24 V DC; battery pack inside control panel.
• Commissioning: drop-test, speed check (0.05–0.20 m/s), side-guide tightness, alarm interface.
8. Maintenance
Six-monthly drop-test and fabric visual; annual full-drop with load test & battery duration check. Record in site fire-safety logbook.
9. Budgetary pricing (FOB Shanghai, Q4 2025)
Smoke curtain: USD 90–130 / m²
Fire curtain EI120: USD 160–220 / m²
Control panel & battery: USD 450–600 set
