CAN SOMEONE ACCIDENTLY PRESS AN EMERGENCY NOTIFICATION WITHIN EMMA?

No need to worry. EMMA has built-in user interface tools to prevent and decrease accidental EMMA use.  EMMA has a password feature and a PIN feature (2-step) to prevent accidental emergency notification triggers. Simply do not share your password and PIN.  In the event of accidental use, it is easy for your EMMA Admin to shut down the EMMA notification in the rare event this would somehow occur.
