Does a commercial abuilding that has both automatic fire protection and full sprinkler have to be inspected monthly?
NFPA 17and 17A [dry and wet automatic suppression systems] require maintenance at least semi annual or more often.
Depends on the type of system. Water bases systems (sprinklers, fire pumps, etc.) must be inspected according to NFPA 25, which require weekly, monthly, quarterly, semiannually and/or annual inspections depending on what the system has. Other non water based systems have their own inspections requirements (usually semiannually and/or annually) depending on the applicable standard.
As mentioned for fire sprinkler systems, there are many checks, mainly visual. These can be done by the owner or one of his employees.
Fire alarm system are kind of twice a year. During that period half the devices are tested and the second inspection the other half are tested.
