# Additional Features

## Motion-Triggered Siren

The internal 110 db Siren is triggered when the device is locked and movement is detected for more than 6 seconds. Once the siren is triggered, it will run for 30 seconds, and then automatically turn off.&#x20;

The Motion-triggered siren feature can be enabled or disabled via a configurable setting on the Fleetview dashboard or in the retail mobile app. There are three available tone settings, which are demonstrated [here](https://www.youtube.com/watch?v=3uuMDuknOsk\&ab_channel=LINKASmartBikeLock).&#x20;

{% hint style="info" %}
Note: By default, the Motion-Triggered Siren is disabled for LINKA GO usage

## Cellular Connectivity and GPS Tracking

Depending on Fleet Settings, a Lock uses cellular connectivity during:&#x20;

* Theft Alert to send location data when locked &#x20;
* A Lock or Unlock event to send location and battery data&#x20;
* During a Periodic Ping&#x20;
* Constantly when in Remote Connected Mode which facilitates Remote Commands.

See the "[Cellular Connectivity](https://docs.linkalock.com/docs/v/leo-2-leo-2-pro/cellular-connectivity-and-gps-tracking)" article for more information.&#x20;

## Firmware Updates
