Gas Net 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 etc. |
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 Gas Net system operates on a single 4-core cable
network and has the capacity to monitor up to 32 addressable
sensors of various gas types. Larger systems offering
unlimited sensors can be achieved using multiple Gas
Nets housed in a 19” rack based system. The Gas
Net 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. When local
indication/alarm functions are required, any number
of Snoop remote alarm panels may be connected, offering
repeat functions of the main panel. |
