A function is given by $f(x)=A\sin (ωx- \frac {π}{6})+1 (A > 0,ω > 0)$. The maximum value of the function is $3$, and the distance between two adjacent symmetry axes of its graph is $\frac {π}{2}$.

(I) Find the values of $A$ and $ω$;
(II) Let $α∈(0, \frac {π}{2})$, and $f( \frac {α}{2})=2$. Find the value of $α$.
