Abstract
The invention relates to a water extinguishing system (1) with a fluid supply (20), a pump (30) and a test line (40) with an opening element (2) which is configured to open the test line (40) during a test run of the pump (30). According to the invention, the test line (40) further comprises a closing element (4) which is configured to close the test line (40) if the water extinguishing system (1) is triggered.

The water extinguishing system according to claim 5, wherein the closing element is configured to move from an unlocking position into a locking position if the water extinguishing system is triggered, in which the closing element closes the test line, wherein the locking position corresponds to an energetically favorable home position of the closing element.
A water extinguishing system, comprising:
- a fluid supply for providing an extinguishing fluid;
- a pump which is configured to pump the extinguishing fluid from the fluid supply into a distribution pipe, and
- a test line which branches off from the distribution pipe and is configured to conduct the extinguishing fluid pumped by the pump,
- wherein the test line has an opening element which is configured to open the test line during a test run of the pump,
- wherein the test line has a closing element which is configured to close the test line if the water extinguishing system is triggered, and
- wherein the distribution pipe has a distribution pipe shutter configured to interrupt a fluid flow through the distribution pipe during a test run of the pump, the distribution pipe shutter further being configured to release the fluid flow through the distribution pipe if the water extinguishing system is triggered.
A water extinguishing system comprising:
- a fluid supply for providing an extinguishing fluid;
- a pump which is configured to pump the extinguishing fluid from the fluid supply into a distribution pipe, and
- a test line which branches off from the distribution pipe and is configured to conduct the extinguishing fluid pumped by the pump,
- wherein the test line has an opening element which is configured to open the test line during a test run of the pump,
- wherein the test line has a closing element which is configured to close the test line if the water extinguishing system is triggered, and
- wherein the water extinguishing system further has a trigger switch, the first trigger switch being configured to close the test line by means of the closing element if the water extinguishing system is triggered.
A water extinguishing system comprising:
- a fluid supply for providing an extinguishing fluid;
- a pump which is configured to pump the extinguishing fluid from the fluid supply into a distribution pipe, and
- a test line which branches off from the distribution pipe and is configured to conduct the extinguishing fluid pumped by the pump,
- wherein the test line has an opening element which is configured to open the test line during a test run of the pump, and
- wherein the test line has a closing element which is configured to close the test line if the water extinguishing system is triggered, and
- the system further having a fire reporting and/or extinguishing control center, wherein the fire reporting and/or extinguishing control center is configured to close the test line by means of the closing element if the water extinguishing system is triggered.
A control unit for controlling an automatic pump test run of a water extinguishing system comprising:
- a fluid supply for providing an extinguishing fluid;
- a pump which is configured to pump the extinguishing fluid from the fluid supply into a distribution pipe, and
- a test line which branches off from the distribution pipe and is configured to conduct the extinguishing fluid pumped by the pump,
- wherein the test line has an opening element which is configured to open the test line during a test run of the pump,
- wherein the test line has a closing element which is configured to close the test line if the water extinguishing system is triggered, and
- wherein the control unit is configured:
- to start an automatic test run of the pump,
- to receive a trigger signal indicative of a triggering of the water extinguishing system, and
- to abort the test run by controlling the closing element of the test line when the trigger signal is received.
