NO. Don't spend time trying to shoot the messenger; besides, the same chime is used for multiple purposes.
There are two frequent conditions for this chime to go off:
1) You left the parking brake on (Duh...
), in which case you'll get the light right away, and the chime will start up once the car detects a movement of 50 feet or more.
2) (More likely in your case) You're low on brake fluid. There'* a sensor in the brake fluid reservoir that will trigger the warning if one or both circuits are low. If a pressure imbalance results between the two (e.g. one circuit goes low and the other doesn't), it may take a bit of driving after you refill the reservoir before the balance is restored and the sensor stops complaining. I had this problem last summer off-and-on before I finally got around to replacing the master cylinder, which had sprung a leak and was seeping fluid out between it and the vacuum booster. If you find the lower half of the vacuum booster is wet with brake fluid (which will leave light-colored puddles on your garage floor), that'* your problem.
