4.1 Fixed sprinkler systems
Figure 14: Sprinkler installation VSH Press Sprinkler
Fixed sprinkler systems are permanently
installed fire extinguishing and fire protection
systems, which independently detect and
report a fire and automatically start the
extinguishing process. The installation of
the VSH Press Sprinkler system in sprinkler
systems is carried out in accordance with
appropriate guidelines (e.g. VdS-CEA 4001).
Depending on the material installed (stainless
or carbon steel), the system can either be
used in wet or dry fixed sprinkler systems.
VSH Press Sprinkler Galvanized is only suitable
for use in fixed wet sprinkler systems,
where VSH Press Sprinkler Stainless can be
used in both wet and dry fixed sprinkler
systems.

With different approvals under which the VSH Press Sprinkler system is installed, also different
hazard classes apply.For more detailed information on applicable hazard classes, please contact
your VSH representative, or VSH Fittings directly.
When the VSH Press Sprinkler system is used, it should also be ensured that no loads can fall onto
the tube network under normal conditions or in the case of a fire; for example ventilation ducts and
cable trays should not be installed above the sprinkler tubes. Depending on your type of system
and the approval which applies to your fixed sprinkler system, different fastener distances apply.
In sprinkler applications the fastener distances for steel press systems are based on the values
used for copper tube. Always follow the valid local guidelines and please make sure to follow
these fastener distances correctly.
