SD-110 is a microprocessor internal 2-channel smoke detector. SD-110 is an environment-adaptive smoke detector which displays the concentration on the back light LCD by receiving the serial signals from two sensors and by processing them in the digital mode, and performs the variety of local functions in digital process mode. Also, it can ensure the effective remote control by stably outputting the analog serial signals to external control unit such as PLC/DDC. As one of big advantages of SD-110, it can be suitably applicable for various purposes by processing the sensible signals detected by ionization sensor by microprocessor stably and accurately. Because the existing smoke detectors have been mostly applied only for a fire alarm, it is general that they don’t ensure an accuracy and safety for a utility of industrial field. SD-110 is designed to ensure a sensibility and safety simultaneously by controlling the sensible ionization sensor with an industrial detector technology.

GMS-2000 is multi-channel digital controller to monitor gas leakages from more than one gas detectors simultaneously. GMS-2000 is composed of one alarming unit & more than one receiving units. While each receiving units in GMS-2000 receive density signals from external gas detectors, when the density becomes higher than alarm value, receiving units automatically give signal to alarming unit to sound alarm. GMS-2000 transmits the relay output and standard current output signal 4-20㎃ to various controllers such as PLC, DDC, recorders, and computers for composition of integrated gas monitoring system.
