Lehigh County Government Center: Weapons policy ? Weapons check-in ?

[ett]

I've searched, but did not find any thread already covering this.

I have a need to go to the Lehigh County Government Center located at 17 S 7th St, Allentown, PA 18101.
Word-of-mouth is that they prohibit weapons there.
Anyone know if they have a weapons check-in procedure ?

Thanks;
