Question 1- Does a single receptacle, in a dwelling, for a septic alarm located in the basement next to the load center have to be on GFI?

Question 2- Does a duplex receptacle, in a dwelling, for a security alarm, with the upper receptacle tabs broken so not energized and the alarm transformer plugged into the lower receptacle and secured with the plate screw and located next to the load center have to be on GFI? It has been indicated by a residential home inspector that all basement receptacles have to be on GFI. Please advise asap. Thank you
