Does GDS need to be integrated with the on-site system, and is CCCF certification required?

Question: Does the GDS system have the capability to interact with devices on-site, in addition to displaying information about flammable and toxic gases? For example, should the sprinkler system at the site be activated when a flammable or toxic gas is detected? Or is there a FAS system to achieve integration with the field? Additionally, apart from the SIL3 certification, does the GDS controller also require CCCF certification?
1. The GDS is used only for alarm purposes; a SIL3 rating is not required, and an independent system is sufficient. For participating in interlock control, whether SIL3 is required depends on a risk assessment; however, in practice, SIL3 is generally used directly. 2. The fire protection function shall be implemented by GDS, and 3CF should be available. It does not need to be implemented by GDS; it’s not required.
GDS is an independent system with separate controllers and operation stations; it is separated from the DCS
