Glue an end cap on to each open end of the pipe system as described in chapter
'Connecting pipes and fittings [
An aspirating hole must be created in each end cap. The aspirating holes in the
end caps usually have a larger diameter than the aspirating holes in the pipes. As
a result of the end cap, an initial airflow is generated in the pipe system.
Exception: The end caps on the upright stand pipes do not have any aspirating
holes in them.

The pipe system can be secured in various ways. Please refer to the following

The basics of fastening
We recommend using fastening clamps, which can be installed on the wall or
ceiling. The pipes are hung in the fastening clamps.
Observe the following points when fastening the pipe system:
The exact installation procedure depends on the fastening clamps used and
the available substructure. Use suitable dowels and screws.
Pipes may expand due to fluctuations in temperature. Ensure that there is
sufficient space for the pipes, e.g. to the side of the pipes.
Ensure that there are no fastening clamps near the aspirating holes.
Do not install any fastening clamps within an area of approx. 1000 mm in front
of the aspirating smoke detector. This simplifies the process of removing the
pipe system from the aspirating smoke detector for maintenance and cleaning.
