I have a question regarding combustible or toxic gas detectors
Thread Content
I’m a beginner. In companies, I’ve seen alarm devices for toxic and flammable gases mounted on walls; some of them are connected to DCS systems, while others use GCS systems that are independent of DCS. There are also layout diagrams for flammable or toxic gas alarms. Could you please explain these in detail, highlighting the differences between them? Thank you very much! !
There’s one mistake: it’s not the GCS system, but the GDS system
It’s not that complicated. The signals are all transmitted from the outside to the interior; they enter the system directly or trigger an alarm inside immediately.

I haven’t worked with the GDS system, and it’s likely that the panel on the wall displays only pages related to alarms for flammable gases and toxic gases. This shows even more that the company attaches importance to relevant alarms. Layout diagram of flammable or toxic gas alarms – we also have this in our DCS, which helps employees know where an alarm is sounding.
Is it better to connect to a DCS or to have it mounted on the wall? How do you compare advantages and disadvantages?
It would certainly be more intuitive to display this page separately on the wall, so that it can be seen by both those inside and outside the facility. Displaying it on the DCS means that only those inside can see it, and moreover, scrolling is required on the DCS; a single workshop typically has more than a dozen process diagram screens.
Display it on a large screen mounted on the wall; it would be even better if there were audio and visual alarms as well (such as warning lights). Of course, the same display must also be shown on the DCS screen at the same time
:) Learn about GDS (Global Distribution System), which is a large-scale computer-based information service system used in civil aviation and the entire tourism industry. Through GDS, travel agencies around the world can obtain a large amount of travel-related information in a timely manner from airlines, hotels, car rental companies, and tour operators, thereby providing customers with fast, convenient, and reliable services. ——From DuNiang ； Don’t understand: P
