Who Complies with NFPA 17A? Tamper Indicators?

Per NFPA 17A section 7.2 an owner's inspection is required for a wet chemical extinguishing system. I'm currently in the process of making a checklist for those systems at my site.

7.2.1 On a monthly basis, inspection shall be conducted in accordance with the manufacturer’s listed installation and maintenance manual or the owner’s manual.

However, how often does the "outside world" comply with this requirement?

I know at the previous site I worked at, we admittedly did not. Also, what are the tamper indicators and seals referred to in paragraph 7.2.2?

7.2.2 At a minimum, this “quick check” or inspection shall include verification of the following: ...
(3) The tamper indicators and seals are intact.

Not quite sure I know what NFPA is referring to there. Thanks in advance for all responses!
