Alert Pin - Active Low on MAX17043 what does it mean?

So this is probably a really simple question, in reading the data sheet for MAX17043 and designing a circuit for it, i came across the following line

Alert Output. Active-low interrupt signaling low state of charge. Connect to interrupt input of the
system microprocessor.

So my question is what exactly do they mean?
Is the line usually HIGH and when the IC detects an Alert it will turn the Alert line LOW?

Yes.
