It seems that some module is going to be installed in this deluge switch panel but it will be provided to JGCME instrument team by JGCME electrical team? How do you plan to perform the connection test during fire and alarm system FAT?AVT considerst that if it is just wired individually between control cabinet and deluge switch panel, we don't need to perform the connection test in advance, but if this will be communicated with the dedicated module in between, it is preferable to perform connection test during FAT. Could you please give us your opinion how to ensure the communication in between.
