The evaluation center of the third generation is designed as a separate device intended for mounting on the surface. It is used to evaluate the signal from up to eight connected gas sensors using RS485. It evaluates the gas concentration in four alarm levels. It is also possible to connect one DEGA ZC II flood sensor and DEGA Tc II temperature sensor. The statuses of all sensors are indicated on the control panel using the LCD display. It is equipped with up to 5 freely configurable relays, an output for optical and acoustic signaling, a current loop for controlling devices with analog input and a USB port for configuration.
