This is a not-so-good slap-on mod. Something is wrong with this. First, they disabled the directional lantern. How would you know which direction it's going? Furthermore, it still uses the terrible logic that pretends that the floor is locked! It also uses an EST Genesis chime instead of a proper LT-Group chime speaker! There is no separate lantern and call button for up and down! Lastly, it still uses this obnoxious alarm that sounds like a smoke alarm! Anyway, use it like a real elevator.
