You can sound the Siren’s alarm by visiting the Action Center in the Ooma Smart Security app and pressing the Sound Siren button.

Once the Siren’s alarm has been triggered, there are two ways to silence it:

• Open the Ooma Smart Security app and disable the alarm by pressing the Silence Siren button.
• Use the Ooma skill on your Amazon Alexa by saying, “Alexa, ask Ooma to turn off the Siren.” If you use this option, the default PIN is 0000. You can use the app to update your PIN at any time.
