Yes.
Tap on the hamburger icon in the top right corner of the WiFi Alarm page to open up the settings of your Chuango WiFi Alarm OV-300/ LTE-400 . Select “Advanced Settings” and customize the alarm siren’s volume (mute, low, or high) or set the duration of the siren when it goes off. The default duration is 5 minutes.
Because the range of the Chuango WiFi alarm hub is not infinite, it is recommended to use a wireless siren such as WS-105 to extend the siren sound in a large house or a multi-story house.
