Jumho Vapour Alarm system continuously monitors inert gas and oxygen percentage and trigger alarm when these over gas percentage limit.

Vapour alarm system include two cabinets, one is acquisition cabinet installed in deck with oxygen and inert vapour sensor; another is an electrical cabinet installed in engine room. Acquisition cabinet transfer signal to electrical cabinet and electrical cabinet provide real time value and alarm status.

Electrical cabinet including alarm indication panel, power supply and relay output. And alarm panels provide 6 LED-digital display and 12 channels LED. Operator can easily check alarm status such as oxygen alarm, pressure alarm, flow alarm etc. The sensor's outputs are continuously supervised by the appropriate individual alarm modules via approved intrinsically safe barriers. This allows installation of the sensors in Class 1, Division 1, Groups B,C or D areas, without using conduits, conduit seals, and explosion-proof junction boxes.
