1 High-pressure centrifugal 4 Control cabinet

2 Temperature monitoring 5 Pressure switch
3 Valve 6 Solenoid valve

Design
Fully automatic fire-fighting system, comprising two high-
pressure centrifugal pumps (1), piping and control cabinet (4)
on a common baseplate. The fire-fighting system comprises
one duty system and one back-up system. Anti-vibration
mounts are fitted at the pump feet and baseplate.
Function
The pump sets are started and stopped as a function of
pressure via an electro-mechanical control system. If the
pressure drops below the set start-up pressure pE , the pump
sets are started via the pressure switch. When consumption
decreases again, the pump sets are stopped as a function of
pressure after the set after-run time (up to 10 minutes).
Independently of the pressure switch, the fire-fighting system
can also be controlled via remote ON/OFF (e.g. a switch in the
wall hydrant). The pressure switch and remote ON/OFF input
are monitored for broken wires and short circuit. If a broken
1968.5/09-EN

wire or short circuit are detected, the fire-fighting system is

started up automatically and a fault is indicated.
In the event of a fire, pumping the fluid handled is of top
priority. In automatic mode, the protection features (dry
running protection, motor protection) cannot be enabled. If
the motor protection switch trips, the motor will keep running
on the power supply network without further monitoring. A
fault message is output.

Selection information

Lightning protection
▪ Electrical installations must be protected against overvoltage (compulsory since 14 December 2018) (see DIN VDE 0100-443
(IEC60364-4-44:2007/A1:2015, modified) and DIN VDE 0100-534 (IEC 60364-5-53:2001/A2:2015, modified). Whenever
modifications are made to existing installations, retrofitting a surge protective device (SPD) in accordance with VDE is
mandatory.
▪ A maximum cable length of 10 metres should not be exceeded between the surge protective device (usually type 1, internal
lightning protection) installed at the service entrance and the equipment to be protected. For longer cables, additional surge
protective devices (type 2) must be provided in the sub-distribution board upstream of the equipment to be protected or
directly in the equipment itself.
▪ The associated lightning protection concept must be provided by the operator or by a suitable provider commissioned by the
operator. Surge protective devices can be offered for the control units on request.

Selecting the fire-fighting system

For selecting the fire-fighting system see KSB EasySelect and/or the Planning Information for Fire-fighting Water Systems
