It can ONLY be used by the Helios sentinel like other specific mods can only be used by other sentinels (like vacuum with carrier).

If you build a helios sentinel you will get the sentinel specific-ability-mods for free (Investigator and Deconstructor).

If you would build a carrier sentinel you would get vacuum and striker.

Now keep in mind, that ONLY the helios sentinel can equip Investigator, which is why it is a specific ability mod.
