The problem comes when you have a sensor going bad, if it is impossible permanently to shut the thing up: now you have 2 things flashing the rest of the flight.
My original panel had an Advanced Flight Systems EMS (best EMS I have ever seen). It had a "Bitch'in Betty" oral warning and flashing both. Acknowledge button only shut the alert down for 3 minutes. Only way to completely shut it up, was to go into settings and change alert parameters.
