There are diesel and gas oil storages in tank farm,
And line-type heat detectors installed on tanks for fire detection,
Then whether the Manual fire alarm boxes needed for the tanks?
I can't find the information in NFPA 72, help please!
NFPA 72 doesn't specify when or where manual fire alarm boxes are required - what NFPA 72 does provide is requirements for how to design and install manual fire alarm boxes. You need to contact your fire protection regulating authority or review the construction specification.
