Does MD building code permit installation of drop-out ceiling beneath fire sprinklers in the basement?

When I purchased my home 7 yrs ago, the home had been renovated, remodeled and basement finished. The basement included a media rooom area- installed speakers, outlets, and adapters available for immediate electronics connectivity. The ceiling was a suspension system with drop-out ceiling panels (making it easy to access cable,speaker, phone wires etc.,) however, the drop-out ceiling panels were installed below the fire sprinklers. This was not noted as a problem.

Recently an incident occured in which a tenant living in the basement claims that the basement is considered "Hazardous Conditions" because the sprinklers were covered by the drop-ceilings which would prevent the fire sprinkler from activating or function properly in a fire.

Please advise:

Does MD building code permit installation of drop-out ceiling and or installation beneath fire sprinklers in the basement?
