AN: You may ask yourself, "Why did the Free Duchy design a sensor module that requires the person who activates it to be cooked alive by the powerful radiation and energies released?" Well, the answer is simple: When they first created it and put in the bio-lock to prevent FOUL XENO INFILTRATORS from using the things against the Noble Human Liberators, nobody told the people assigned to the things that they were supposed to leave after activating it. They were, in fact, told to shut up and do their duty when asked how to operate the things. So, after some decades, when a Magus of the Mechanicus was confused about how there was a 1-to-1 casualty rate to the system's activation and investigated, they were told that "this is how it is done" by the menial clans that service these sensors. And since breaking with tradition is Heresy...
