In the MLAR 10/2016 Model Guideline for routing Systems, a wide variety of options are listed that enable sufficiently long use of necessary stairwells, rooms between necessary stairwells as well as exits to the outside and necessary corridors as escape routes in case of fire. These include suspended ceilings with fire protection requirements according to section 3.5.3 of MLAR 10/2016.
ith the MLAR - installation systems, tested in accordance with DIN 4102 Part 12 according to the unit temperature-time curve (ETK), Niedax offers you a wide range of solutions.
The MLAR installation system RLC 60 or RS 60 uses cable trays with a rail height of 60 mm in widths of 100 to 400 mm or 100 to 600 mm.
Two lengths of cable tray RLC 60 are connected using the 2 splice plates RVC 60 and the joint bar RSLC with mushroom-head bolts FLM 6X12, while the cable tray RS 60 is connected using the RV 60 and mushroom-head bolts FLM 6X12 included in the scope of delivery.
The position of the joint connections is not bound to a specific position.
Any horizontal and/or vertical change of direction can be realised on site with the fittings as well as the angle and splice plates. All changes of direction must be supported in the immediate vicinity of the joints (distance ≤ 150 mm) by an appropriate supporting structure.
In the case of horizontal routing with height offsets, the inclined cable tray must be fastened to the bracket KTA using cable tray fasteners KLAF 6. The fastening plate KLAF 6 can be adapted to any incline angle by bending it by hand.
To protect the cables, use edge protectors RKB at the cable tray ends.
For ceiling mounting, the overhead hanger HU 5050 or HU 6040 or, for greater flexibility on site, corresponding U-profiles and head plates are available.
When mounting the bracket KTA on the overhead hanger or U-profile, the overhead hanger-distance profile HDS must be used.
The M12 threaded rod is mounted with the RGAB 12 F support bracket on the cable tray side rail in the immediate vicinity of the extension arm.
