Installation of the Pipe System
At the very least, the pipes and fittings used for the pipe system must comply with class 1131
according to EN 61386‑1, 2004. Class 1131 requires the following of the pipe system in use:
Features
Compression resistance
Shock resistance
Temperature range
The pipe system must be constructed using the following pipes and the associated fittings:
Smoke aspiration
pipe
* PVC pipes do not correspond to the temperature range given above.
For pipe systems with long pipe feed lines (see also Planning for Long Pipe Feed Lines, page
58), you must also use the following pipes and the associated fittings:
Smoke aspiration pipe
Notice!
When constructing the pipe system, observe the temperature range specified under Pipe
System, page 29 in the Technical Specifications chapter.
The pipe system must be constructed according to planning specifications and must take into
account the planning guidelines.

Notice!
If halogen-free plastics must be used, the installation procedures may vary depending on the
selected material:
ABS is glued
Polypropylene (PP) is welded
Polyamide (PA) is pushed together and bolted.

Shorten the pipes with a pipe-cutter (38 mm) or a metal saw. Deburr the joints and clean
up the chips.
Before gluing, clean the adhesion points with the prescribed cleaning agent (Tangit) to
remove dirt and grease. Use the Tangit adhesive to glue the pipe transitions with the
appropriate fittings so that they are airtight.
Minimize pipe lengths and changes of direction. Pipe elbows have an extremely high flow
resistance. Therefore, they should only be used where they cannot be avoided for
structural engineering reasons. If necessary, reduce pipe lengths in proportion to the pipe
elbows used.
