The gateway door chime is controlled using the web app's sound settings (off, low, or high). This also controls the chime on the indoor siren (on or off) but NOT the volume.
You can change these features by accessing the web app. Go to System Settings>>Sound Settings, then choose when you would like the gateway and indoor siren to provide the chime sounds.
How do I control the door chime sound on the indoor siren?
