4.6 Configuration and function
Fig.3: Illustration of the fire-fighting system
1 High-pressure centrifugal pump 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 p
the pump sets are started up 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 10minutes). 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 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.
