So since I dont have a stealth, I initiated combat manually and tried to close the distance to the ironhead hammerfriend, he used his MP and AP to try to get close to the Switch (pointer indicates where he got so far) to active the alarm as usual, however when he ran out of MP and AP, he activated Sprint and actually he run towards me, and not the switch.
Now that I mention it, I find how he activated sprint when he ran out of AP, whereas he should have used it at the start of his turn.
