2.3 Alarm Function
• Geo-fencing alarm
GT300 provides Geo-fence features that can be used for territory management,
prohibited locations, and more. GT300 will automatically send alarm message to the
monitor center if the person carrying it enters and/or leaves the predefined areas.
• Remote control alarm
The monitor center requests GT300 to send back its location periodically (e.g. pre-set
1 minute), if the device can not send back its location, the device will be considered to
be in an abnormal status.
• Over-speed alarm
Once the velocity of GT300 goes beyond the preset limit velocity (e.g. pre-set 120
Km/h), it will send alarm message to the monitor center.
• Low power alarm
The message of low power notification will be sent before the battery dies out.
• Falling alarm
If GT300 detects falling (e.g. tumble), it will send the alarm message to the monitor
center.
