Selection Notes

XVB7C9S adds an audible channel to a Harmony XVB7 assembly without taking up a light-module position, since it mounts as its own tier above the base. The 88–102 dB adjustable range and DIP-switch tone selection let one module cover both a quiet indoor cell and a noisier shop floor by changing the setting rather than the part. Add it when operators are not consistently facing the tower, or when the base module chosen for the stack does not already have an integrated buzzer.
