Conector 230V AC PREALARM: This output its timed to activate the extraction during 2 minutes. IT SHOULD NOT ACTIVATE ALARMS Between C & NO (ALARM) Between C & NC (GAS CUT) 230V CA Outputs Do the connection between C & NC or C & NO, being sure that the devices connected (electrovalve, contactor, siren, etc.) work at 230V and total consumption does not exceed the B fuse value of 2A. 12V CC Outputs Do the connection between C & NC or C & NO, being sure that the devices connected (electrovalve, contactor, siren, etc.) work at 2V and total consumption does not exceed the C fuse value of 0,5A. Example of 12V output connection to an electrovalve FIDEGAS CA2. Conector 12V DC Dry contact (close contact and no powered). Between C & NC (ALARM) Between C & NO (GAS CUT) CONSIDERATIONS: When connecting 230V -or after a main fault- wait for 30 s before REARMING the system. Pay attention to the fuses capacity (mentioned in the manual) When all fault LEDs will be lightining up, check the state of the fuse ( D - E ) FIDEGAS CA Quick installation guide
