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. |
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
of various gas types. Larger systems offering unlimited
sensors can be achieved using multiple combi units housed
in a 19” rack based system. The Combi is supplied
ready to use with precalibrated gas sensors and provides
for additional sensors that can be easily added to any
point of the network. |
