When performing a 5 year internal inspection on a wet/dry fire sprinkler system, is it required to perform all items which are included for the annual inspection, and then so the 5 year internal is accepted as the annual inspection.
If you want to sign off as an annual, than yes all annual items have to be done.
A possibility is that these will happen on two different visits.
Its required for all items check by NFPA 25. where some items check visually and some items check functionally. Just follow NFPA 5 years , yearly, monthly, quarterly, weekly maintenance.
