Active-80

Key Product Features

  • Multi-channel, addressable system
  • Engineered solution for larger systems
  • Reduced cost installation and maintenance
  • Data logging and digital comms capable

The brief was simple, you told us that you wanted one instrument that can monitor up to 80 potential gas leak points, be flexible enough to make installation quick and easy, be able to operate in a multitude of environments and industries, and more importantly to be able to monitor and detect a full range of gasses using all the sensor types available, and while being technologically advanced it must be simple to operate and maintain.

The result is the Active 80. One of the most advanced gas detection systems on the market (as would be expected from GMI, a world leader in gas detection). 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, etc.

Because you need to know what’s happening in your environment, each gas sensor is continuously monitoring and reporting back any hazardous conditions to the control unit for display on the alphanumeric screen, showing you the sensor ID, the gas type, the concentration and the alarm status. If an alarm level is exceeded the Active 80 automatically activates a variety of signal outputs including analogue/digital data and user selectable relays, along with this it has full data compatibility with serial RS232 and RS485 outputs and is fully Mod Bus compatible.

  • Up to 64 addressable sensors
  • 1-16 direct 4-20 mA sensors - 2/3 wire
  • Single 4 core sensor network (addressable)
  • On screen text description of sensor locations
  • 3 alarm levels
  • Event - data logging
  • Low cost installation
  • Repeater panel – option
  • Up to 64 Additional relays
  • One man calibration
  • Automatic safety check diagnostics / system surveillance
