A fire shutter works like a firewall as a horizontal divider, usually where a firewall is hard to fit, such as open elevator halls, escalators, wide department-store floors, exhibition halls, and large openings where fire doors and windows will not do. In construction, fire shutters see wide use for compartment.
Install requirements:
1. No vent or water pipe above the shutter opening.
2. The user lays power lines (three-phase five-wire and fire control signal) to the control box by the motor.
3. After install, fit the ceiling; keep its edge 50 mm from the curtain plate to avoid friction.
4. In debug and use, no one under the shutter. Do not move electric parts on your own.
5. Per fire rules, the fire shutter is a fire-only facility, not for other use; nothing stacked right below it.
6. After install and debug, start it once a quarter to check electric and mechanical performance; mind safety.
7. By install form: in-wall or side-wall (in or out of opening). By open direction: top-roll or side-roll.
By material:
1. Steel fire shutter (F1, 1.50h): steel curtain plate, rail, seat plate, lintel, box, with motor and control box, meeting integrity.
2. Inorganic fiber composite fire shutter (F2, 2.0h): inorganic fiber curtain, steel splint, rail, seat plate, lintel, box, with motor and control box, meeting integrity.
3. Premium fire shutter (F3, 3.00h): steel or inorganic fiber curtain, steel rail, seat plate, splint, lintel, box, with motor and control box, meeting integrity, insulation, and smoke control.
