Help me, I’m a newbie in design; I’m facing problems and it’s very frustrating!

Gentle experts, the master isn’t here – please save me! ! In the field of fire protection, it is necessary to enable the electric valves in the tank farm fire protection systems to be switched on/off remotely from the control room. I’m confused about how instrumentation and fire protection systems should divide up the tasks involved; who is responsible for selecting the electric valves? Who will take the call? How does the instrument achieve this function? ? ? ? ? Waiting online, urgently! ! !
It’s all related to instrumentation work, except for the installation of valves on pipelines.
Generally, the instrumentation team is responsible for selecting the equipment and handling the wiring, while the fire protection team is in charge of finding someone to install the valves and run cables to the control room. As for exactly how this is done, it’s hard to say – the information you’ve provided isn’t complete enough
The design for this tank area has been completed and the drawings have been sent out; it was only then that the fire department realized they hadn’t specified the requirements for the instruments, and those requirements were put forward today! It’s driving me crazy! Moreover, they’ve already chosen the electric valves for the fire protection system, and they’re still 380V! !
First: Should it be integrated into the DCS, or just digital displays or control cabinets installed in the control room for control? Second: Does the electric valve receive digital signals or analog signals? Third: Is a feedback signal required?
Firstly: It is sufficient to be able to perform remote switching from the control room, whether through soft control or hard control. Given the current capacity of the buttons on the control room’s auxiliary console, DCS soft control is the preferred option； 2: It is an electric on/off valve, with digital control. 3: If the function is to be implemented on the DCS interface, it is advisable to include the valve position feedback signal as well; if the function is implemented on the auxiliary control panel, then valve position feedback is not necessary
Then you just configure it in DCS. Is there anything else to ask? You’re not asking how to configure it, are you?
