Can u turn down volume on the gongs ( dir arrows ) on a 330 a Schindler unit?

well rat,
if it's an electronic chime, they are typically sealed. yet some have a have a small distinct hole in the face cover and the volume control pot can be seen inside, then it's just a matter of cw/ccw to achieve your desired volume. if they aren't this type (i.e. sealed w/no control or mechanical bell), replacements are available which give you that option.

A little tape works wonders it there's no adjustment on it

Would it be in the push button ... The speaker wires run down and hook to it I see 2 dials on it but it is not clearly labeled

Ratman is correct.

I tape them. It's ridiculous how loud those damn sec gongs are.

Found volume it is in the very back of board mounted in back of box ... Pain in the butt to lower volume on 16
