Accumulator
Pressure losses may occur in the piping system
downstream of the break tank package booster
set for fire fighting which may be caused by
leakage of small quantities of water. The
accumulator serves to compensate pressure losses
and minimises the frequency of starts of the break
tank package booster set for fire fighting.
Back-up system
The part of the fire-fighting system / break tank
package booster set for fire-fighting which
ensures the supply of fire-fighting water in the
event of a fire if the duty system fails (see also
duty system).
Certificate of decontamination
A certificate of decontamination is enclosed by the
customer when returning the product to the
manufacturer to certify that the product has been
properly drained to eliminate any environmental
and health hazards arising from components in
contact with the fluid handled.
DIN 1988
German Standard which stipulates technical rules
for drinking water installations.
DIN 14462
The fire-fighting systems / break tank package
booster sets for fire fighting must comply with the
German standard for water conduits for fire
extinguishing.
Duty system
The active part of the fire-fighting system / break
tank package booster set for fire-fighting which
ensures the supply of fire-fighting water in the
event of a fire (see also back-up system).
Flushing
If the volume of the inlet line exceeds 1.5 l and/or
the length of the inlet line ≥ 10 × DN, a flushing
system must be provided. This will prevent
stagnating fluid handled and microbial
contamination of drinking water.
IE3
Efficiency class to IEC 60034-30: 3 = Premium
Efficiency (IE = International Efficiency)
Manual mode
Direct operation on the power supply network,
independently of the control unit.
Pump activation
Pump activation means that a pump is started up
by a starting signal from the pressure switch, from
a wall hydrant (limit switch) via remote ON/OFF, or
from the broken wire and short-circuit monitoring
relay.
Rainwater storage tank
Tank for collecting rainwater, for buried
installation or above-floor installation
Switchgear and controlgear assembly
Control cabinet with one or several control units /
switchgears and electrical equipment.
