GI30WN and GI30WK are three-stage detectors designed to detect flammable gases or substance vapors. They are used in larger buildings such as boiler rooms or storages of flammable substances. They are also used in parking buildings to detect leakage of LPG or CNG, however, in this case it is necessary to consider the possibility of false alarms due to other flammable substances.
A part of the detector is a separate temperature sensor, which corrects the effect of a temperature change on the sensor sensitivity. The detector output includes a galvanically isolated switching line. Both versions are identical in terms of electronics and gas detection.
The versions are different in mechanical design. GI30WN is suitable for fixed mounting in accessible sites. The inspection is carried out on site. GI30WK with its easy assembly and disassembly thanks to the clip attachment is designed for inaccessible places or for places where more frequent replacement of the detector is expected.
