The bell shouldn't start ringing as you power up. On some decoders under DCC, doing a quick flick back and forth of the direction switch triggers the bell I believe. A couple of companies have DC add-on devices which allow you to access the features of a DCC sound decoder, like bell, whistle etc. by using pushbuttons like the function buttons on a DCC controller.
That's the proper operation according to the directions included with the locomotive.
You slowly bring up the power, the sounds start up around 5 volts, as you keep going the bell rings and the locomotive whistles off and starts moving. Once at a certain speed the bell shuts off.
And the opposite is also true. When you slow to a certain speed the bell starts ringing.
