Today I get a termine control consultant to check on my new house, and he advise to me was doing nothing since all my tiles are new, except I want to make hole on each feet . And he indicated that I should do before tiles in place lol.

Hence for those people who mid doing renovation which involve hack they Grd Floor tiles, you may want to consider implement termine control before new tiles in place, which at least worry free for next 5 years.

The Sentricon is just another type of challenge,the termine may bypass it as well, as it just like a station if the bus (termine) decide not to stop at the station...
