Combi has been designed to operate in the full range of environments from commercial premises through to heavy industrial applications which may require hazardous area sensing. Typical monitor locations are – public buildings, car parks, tunnels, breweries, boiler plant rooms, water treatment works, H&V control, manufacturing,process plants, horticulture, hotels, offices.For the UK facilities, Flame Arrestors UK offer crucial safety features to guard against the risk of fires in areas where gas or combustible materials exist. The Combi system presents a dependable answer for protecting these areas.

Operation

  • Each gas sensor continuously monitors the atmosphere reporting any hazardous conditions to the control unit for display by the alpha numeric screen indicating the reporting sensor, gas type, concentration and alarm status.
  • Alarm levels that are exceeded will automatically activate a variety of signal outputs including analogue/digital data and user selectable relays.
  • The Combi system operates on a 4–core (addressable) or 2/3 core (direct) cable network and has the capacity to monitor up to 64 addressable and 16 direct sensors 8 of which will accept the CC-1 bridge converter module.
  • Larger systems offering unlimited sensors can be achieved using multiple combi units housed in a 19” rack based system or a network controller.
  • The Combi is supplied ready to use with pre–calibrated gas sensors and provides for additional sensors that can be easily added to any point of the network.
  • Optional software (Combi Soft) allows full data logging facilities with system management providing real time views showing sensor locations, alarms status and actual gas values.
