Anti-flood system is a system for reliable protection against flooding in the event of a breakdown of your heating and water supply systems of a house or apartment. The Anti-flood system consists of: a remote control unit, flood sensors and actuators that turn off the water supply when a leak is detected. Water leak sensors are installed in rooms where water leakage is possible. Actuators must be installed on the water supply. In the event of a water leak, the flood sensor transmits a signal to the system control unit, which, in turn, transmits a command to the actuators to turn off the water.
