4. Intrinsically Safe Telephone
Intrinsically Safe Telephone system is designed to communicate at dangerous locations in the vessel (either at normal conditions or in the area with the possibility of explosive gas in case of accident), as it performs perfectly for the intrinsically safe construction. The structure of this system is carefully manufactured to be humidity, water, shock, and corrosion resistant in consideration of the maritime environment. The quality of voice signal and side tone was improved by adopting a low-noise OP-AMP in the telephone. Noises induced from the voice transmitter were remarkably reduced by using the circuits with high common mode rejection ratio.
The system was tested at the IEC60945 standard and approved for CE.
