By the way...
The Dornier 328 does have an inhibit function on its fire warning tone. (It uses a tone generator rather than an actual bell.) You get the Master Warning and the Fire Warning lights but the tone doesn't sound until you have passed a certain time/height boundary. (I'm not currently flying the type so that I cannot tell you the exact values but there is probably a 328 pilot here who can say what they are.)
This particular set-up could trigger an abort with a warning below 80 knots but a go with a warning between 80 knots and V1 if it was not noticed as a fire warning, since part of the usual brief is something like ".... abort for any red warning below 80 knots, abort for fire, blocked runway or loss of control between 80 and V1..."
I would have thought that if you had briefed for an abort for a fire below V1 then you should follow the brief and abort. Otherwise wouldn't you simply want to nominate a different V1 to suit the circumstances? The ideal is that a chosen V1 should allow a safe abort, isn't it? If one briefs one way and then acts in another way, well, that sort of makes a nonsense of doing the brief in the first place. Think of the poor old FO who would have to think, "This is Captain X who will probably want to abort," or else, "This is Captain Y who will probably want to go," and then hope he guesses right on the day. You could call that bad CRM!
