Installing roller and fire-rated shutters must be done by a pro from the maker. Buying from a maker usually includes install and after-sales repair. RHidoor is one such full-service company. Watch these points during install.
Curtain slat install:
1. Linked steel fire slats should turn freely; swinging 90° should not drop them.
2. After assembly, steel fire slats should be straight, with no holes or gaps.
3. End baffles or anti-shift parts should be firm. During travel, shift between adjacent slats under 2 mm.
4. Inorganic fiber composite fire curtains should have wind hooks at both ends.
5. The inorganic fiber composite curtain should link to the shaft via fixings.
Rail install:
1. The depth the curtain embeds in the rail should meet the table. When rail spacing exceeds the table, each extra 1000 mm adds 10 mm embed depth per end, and the shutter should not deform after install.
2. Rail tops should be arc-shaped, long enough for normal travel.
3. Rail sliding faces should be smooth and straight. Slats or rollers should run steady and smooth, no bump or hit.
4. The two rails of a single-curtain shutter should be parallel; different curtains of a twin-curtain shutter should also be parallel. Parallel error under 5 mm.
5. Rail vertical error after install vs base under 1.5 mm/m, total under 20 mm.
6. The smoke seal should fit the curtain evenly and tightly; fit length at least 80% of rail length.
7. Rails should mount on the building structure via embedded bolts, welding, or expansion bolts. Firm, fixed points 600 to 1000 mm apart.
Bottom plate install:
1. The seat plate should be parallel to the ground, contact even. Link to slats or curtain firm.
2. The inorganic composite seat plate should let the curtain descend smoothly with proper sag.
Lintel install:
1. Lintel firm, fixed points 600 to 1000 mm apart.
2. The smoke seal in the lintel should fit the slat or curtain surface evenly and tightly; fit length at least 80% of lintel length; gaps in non-fit parts under 2 mm.
Drive unit:
1. Shaft and bracket plate should mount firmly on concrete or embedded steel.
2. Shaft deflection in use under 1/400 of shaft.
Shutter motor:
1. Install per the manual, firm and reliable.
2. The motor should have a manual chain and manual quick-release, placed for easy reach and clearly marked. Not locked, and made of non-combustible or hard-to-burn material.
Protection box:
1. Box size should match the opening width and rolled shutter size, and keep a gap from the cover when full, no clash.
2. Near the motor, leave a service opening.
3. Box fire rating should match the shutter.
Controller:
1. Controller and manual button box should mount on both inner and outer walls. If one side is unmanned, mount on one wall per design. Both should be easy to spot and marked with up, down, stop.
2. Controller and button box firm, bottom 1.3 to 1.5 m above floor.
3. Metal parts should have a ground point with a clear mark; the ground screw should not serve other fastening.
The thermal release device position should match the design and manual. Gaps between shutter, box, and floor, beam, wall, column should be sealed with fire-stop material. The seal’s fire rating should not be below the shutter’s.
