2 Installation Steps
These instructions are the basic sequence of steps you will be required to perform when installing a pipe
network. Information on installing into a range of environments is covered in depth in Chapter 5. Information on
the theory of good pipe network design can be found in the VESDA Pipe Network Design Guide.
2.1 Pipe Network Installation
The normal procedure for installation is:
1. Check the design documents to gather information on the size and configuration of the pipes. The
design documents could include pipe network design specifications, an ASPIRE Installation Data
Pack (IDP), or a pre-engineered design.
2. Mark the spots where the detector is to be installed.
3. Measure and mark the spots for pipe mounting clips as per the design documents.
4. Install the detector. For further information refer to the detector documentation.
5. Install the mounting clips as per the design documents.
6. Mount and join the pipes onto the clips, as per the guidelines in Section 4.4. Do not glue the pipes at
this stage.
7. Drill sampling holes in the pipe ensuring that the spacing between sampling holes is as per the design
documents and the holes are at the correct orientation.
8. Check if the design documents require end caps with holes. Install as required.
9. Run the pipe to the detector.
10. Insert the pipes into the detector ensuring there is a minimum of 500 mm (20 in.) of straight pipe before
the pipe enters the detector. Do not glue the pipes to the detector manifold.
11. Update the design documents with any changes that may have been made to the original plan. If the
installed system is significantly different to the original plan you may need to use ASPIRE to check
that the new design will actually work.
12. After all the tests have been completed bond the pipes together using the appropriate cement solvent.
Do not glue the pipes running into the detector manifold, as this can make it impossible to service the
detector, and will void the warranty.
13. Use appropriate labels and tag the sampling pipe and sampling holes.
14. Update the design documents with any further changes that may have been made during the tests, and
give a copy of the updated design documents to the person who will be commissioning the system.
