Oh yeah.. you're right. Sorry I was upstairs and the lack of oxygen was getting to me... I was indeed confusing the steady and intermittent warning horns.
Nevertheless I think I made a point by mistake, which is that it is a potentially confusing setup. The fact does remain though that someone somewhere thinks the system is such to warrant the fitting of the Takeoff Config/Cabin Alt annunciators on both the left and right forward panels on new 737s. That bit was not rubbish.
