5. Functional description

The starting signal for the fire pump is given via two redundant
pressure switches. The fire pump can only be switched off
manually.
The control of the fire pump has been arranged in such a way that
motor failures, for example due to heating, do not cause the fire
pump to stop, but only in fault indications and/or a potential-free
signal to a superior fault centre.
In addition to the fire pump, ancillary VdS-approved equipment
can also be controlled.

6. Construction

The control cabinet made of steel sheet is protected against
ingress (IP54). The standard colour of the cabinet is red
(RAL 3000). The mounting plate is made of 3 mm galvanised
sheet steel.
The cabinet design depends on the selected options and the
performance of the fire pump. The dimensions of the control
cabinet depend on the number of options installed and on
whether the controller is wall-mounted or free-standing.
Cables of wall-mounted controllers enter through cable glands.
Cables of free-standing controllers enter a 100 mm high base
frame and a bottom plate split in three parts.

6.1 Control panel

The control panel design depends on the selected options.
The control panel has a number of standard components
(all models) and optional components (selected options).
