Designed to conform with DIN 14462, the fire-fighting system uses only one main fire-fighting pump to supply hydrants installed above-floor or underfloor with up to 192 cubic metres of fire-fighting water per hour in the event of fire.

The system, exclusively manufactured in Germany, has been developed for supplying fire-fighting water to protect multiple dwellings, residential and office buildings, multi-storey car parks and hospitals.

The fully automatic break tank package booster set for fire fighting is fitted with two fully redundant pumps, each of which has got their own power and control circuit. Their redundant control systems continuously monitor pressure switches and limit switches for broken wires and short circuits. Motor protection and dry running protection are disabled in the event of fire, making sure the pumps do not stop before fire fighting has ended.

The master switch and valves are secured against unauthorised operation. If one of the pumps fails, the redundant control system takes over and starts up the second pump. This provides a high level of safety for the operator, the buildings to be protected and the infrastructure.

The break tank ensures that drinking water and fire-fighting water are hygienically separated to EN 1717 type AB. The net tank volume meets the 3% rule stipulated in the standard. The modular design makes the system easy and fast to install and connect to the water supply. Emergency drainage of the break tank is not carried out by the fire-fighting pumps but by a separate solution matched to on-site conditions.

An automated daily functional check run increases the operating reliability and ensures that the operator is always informed about the operational status of the system.
