The FGD14 series are stand-alone gas detectors with a front panel display of the gas level. The detectors contain 2 control relays that can be activated via user definable alarm set points; the relay contacts can then be used to control external equipment.
An audible/visual remote unit is also provided with the detector. Typical applications include water purification processes, food preparation and/or storage, car parks, swimming pools and medical applications.
Models are available for powering from either:-
A mains supply of between 85 and 265 volts ac
