10 Advantages of Multi Pipe Systems
Subject to the maximum length parameters for the detector it is possible to design a pipe network covering an
entire zone with one pipe. However, for improved pipe network efficiency we strongly recommend you use
shorter multiple pipes.

The advantages of multiple pipe systems are:
l
Shorter pipes have better response times as the air transport distance from the end of pipe to the
detector is reduced. Refer to Section 9.2 for details.
l
Shorter pipes have less sampling holes per pipe and can have smaller endcap holes. This creates better
hole share and hole balance. Refer to Section 9.1 for details.
l
Shorter pipe lengths are likely to have fewer bends resulting in shorter transport times and better air flow
l
System balance: multiple pipes provide better system balance
