SUSPENSION SYSTEM TECHNICAL GUIDE

DATA CENTRE CEILING SOLUTIONS

TECHNICAL GUIDEThe Prelude® 24 MaxTM suspension system for data centre applications is a pre-engineered ceiling suspension system designed for improved air flow management, load carrying capacity, and adaptability in data centres of all sizes.

The Prelude 24 Max suspension system uses M10 threaded rod support and reconfigurable load connector clips to support cable trays, bus bars, hot aisle containment, and other components to provide maximum load carrying capacity and flexibility, while eliminating the need for a separate strut channel suspension system.

Code Compliance You Can Trust

Suspension system meets:

• EN 13964

• ASTM E580

• ICC-ES AC156

Seismic D, E, F configurations available.

Prelude 24 Max24 mm Suspension System

– Supports load from the face utilising M10 threaded rod and integrated hanging clips.

– Allows for flexible and reconfigurable overhead cable trays, electrical distribution and hot aisle containment to meet client needs without a separate strut channel system.

SUSPENSION SYSTEM COMPONENTS

KEY ATTRIBUTESPrelude® 24 MaxTM Suspension System

• 600 x 600 mm suspension system supports load from the face of the suspension system using M10 threaded rod and integrated hanging clips:

- Allows for flexible and reconfigurable overhead cable trays, electrical distribution, and hot aisle containment to meet client needs without a separate strut channel system

- Eliminates unsightly threaded rod penetrations through the ceiling plane for improved access and aesthetics

- Reduced ceiling penetrations help minimise unwanted air infiltration

• In seismic areas, suspension system meets ASTM E580, ICC-ES AC156 with Seismic D, E, F available

• C2C Silver certificated suspension system

• 30 year system guarantee

SEISMIC DATA

SEISMIC INFORMATION

IBC categories D, E and F must also meet these additional requirements:

• Structural Wall Angle is to be used along the perimeter with a XTAC clip attaching the grid to the Perimeter Trim, along fixed walls only.

• Grid must be attached to two adjacent walls – opposite walls must have a 2" (≈ 51 mm) clearance in accordance with ASTM E580.

• Ends of Main Runners and Cross Tees must be connected together to prevent their spreading. These should be locked into place using the Lateral Support Bar.

• Ultra Heavy-duty grid system. See load data.

• Ceiling areas over 1,000 SF (≈ 93 m²) must have standard rigid bracing for the grid.

• Ceilings without rigid bracing must have 2" (≈ 51 mm) oversized trim rings for sprinklers and other penetrations.

• Changes in ceiling plane must have positive bracing.

• Mechanicals (Cable trays, electrical, etc) may be attached and supported by the ceiling grid, per our instructions. However, mechanicals must be seismically braced by others.

• Suspended ceilings will be subject to special inspection.

NOTE: Consult your local code professional for information specific to your region.
