P3 AVSU Modules
P3 AVSU Modules
A pre-piped module cuts site work: instead of installing each isolation valve and pressure sensor separately, the complete assembly arrives on one backplate ready to fix and connect. P3 offers three versions depending on whether pressure sensors and an area alarm panel are included.
What is it?
The 1st fix is delivered pre-piped and tested on a steel backplate with copper stubs from 22 mm to 42 mm. On the sensor versions the pressure sensors and electrical connection boxes are pre-wired, simplifying area alarm connections on site. A white powder-coated 2nd fix fascia with individual AVSU doors is then fitted, available surface mounted or semi-flush.

Frequently asked questions
What is the benefit of pre-piping?
It reduces brazing and wiring on site and speeds installation, since the most demanding part arrives assembled and tested from the factory.
