The device carries on sensing the temperature at the ABR and will transmit
an ABR beacon when the temperature returns to within the acceptable
threshold. This beacon resets the Temperature Alarm Flag.
The alarm beacon rate can be set as a value of 0-254 minutes
Setting the value to zero disables the ABR.
ABR payload contains last known GNSS coordinates, it does not activate
the GNSS module for ABR beacon. The GNSS module is only activated post
device movement.
Motion Alarm Beacons are transmitted under the following situations:
•
Motion detected: The device transmits a single beacon when it
senses motion, it sends its last known location, sets Motion Alarm
Flag and GNSS Lock/fix Flag not set. The device will only send
1 Motion detected triggered beacon while moving.
•
Motion Stopped: The Device transmits a single beacon when
it senses that movement has stopped, it sends its last know
location, Motion Alarm Flag is not set and GNSS lock/fix flag not set.
•
The GNSS module is activated when the device is stationary post
motion for a period greater than 1minute. Once it has achieved a
GNSS fix based on user configurable settings the device sends its
current position, Motion Alarm Flag is set and GNSS lock/fix flag
set.
If the GNSS module fails to achieve a lock/fix within GNSS Max lock time
which is user configurable the device will reattempt after a period of 10
minutes.
GNSS lock/fix is attempted a total of four times, if the lock/fix is not achieved
after three reattempts the device will beacon the position achieved on final
