The CIS 3100 is Jotron's Phontech Command Intercom System which is specifically designed to provide communication links onboard ships and boats.
The new design is very compact, and the performance is enhanced by use of microprocessor techniques.
The CIS 3100 System consists of a line of 3 different master stations: type 3100 (5 ext.), 3101 (10 ext.) and 3102 (20 ext.), together with various quantities of substations from the 9000-series.
The new compact design is according to DIN 144 standard sizes, harmonizing with our other models for console mounting. The front is a black touch key panel, with integrated operator switches, indicator LEDs, loudspeaker, microphone and volume control. The operation is simplex, controlled by the master station with priority.
These new master stations are electrically compatible with previous Phontech models 3000/3001/3002.
