System for testing fire suppression installations

Abstract

System for testing fire suppression installations comprises a model fire source, a control unit, a temperature sensor, and a fire model implemented using resistors, a capacitor, and DC amplifiers. System includes a converter that transforms the spray water flow rate into an electrical voltage, an algebraic adder, a switch, and a comparator, the output of which is connected to the input of the control unit, the first output of which is connected to the control input of the switch, the second output of the control unit is connected to the control input of the fire suppression installation, the third output of the control device is connected to the second input of the comparator, the first input of which is connected to the output of the switch, the input of which is connected to the output of the algebraic adder. The output of the converter that transforms the spray water flow rate into an electrical voltage is connected via the fire model to the "–" input of the algebraic adder, the "+" input of which is connected to the output of the temperature sensor and to the input of the fire suppression installation.
