MONITORING UNIT MPU6C (SAMON: 20-305)
- Product group:
- Product number:
The MPU6C are central units with six channels (detectors). They offer an ideal solution for multi-point surveillance of small/medium-sized rooms where refrigerant leaks may happen. The microprocessor-controlled unit displays operating status and alarm information independently for each channel via (LEDs). They are suitable for monitoring all HFC & HFO refrigerants. The connected detector continuously measures the gas concentration and provides an analogue signal to the central unit. Alarms are indicated in three levels by a yellow and two red LEDs that indicate low (Alarm C), medium (Alarm B) and high (Alarm A) gas concentration, the respective LED lights up and the corresponding relay switches. If the alarm delay selected flashes each LED in the selected delay time, then the LED turns to steady and the relay contact switches.
