BuzzLinc Problem

I placed a jumper across GND and N/O on an IOLinc (#2450) and a piezoelectric buzzer (21N30PQ) connected to 5V and COM. The IOLinc linked first try. Turning the device on produced an audible click but no buzzer. Not being familiar with the IOLinc, is there a potential polarity issue since the buzzer has positive and negative posts? Any suggestions?

The (+) terminal of the piezoelectric buzzer should be at 5V and the (-) terminal at COM.

Thanks. I updated the BuzzLinc instructions.
