Programming
Unit initialisation
The unit will immediately attempt to connect to the BT Redcare platform over the
mobile paths. The unit will typically complete path establishment in the following time
from power up.
The unit sends a ‘System Reset’ event (Pin 984,1) over the first available path, followed
by a ‘Unit Restarted’ restore (Pin 984,3) within two seconds. The unit also sends the
state of all 8 pins and low battery alarm restore. Sending these alarm states at start up
helps to ensure that the ARC alarm handling software reflects the true state of all pin
alarms after start up.
Status display
The unit clearly displays its status on the OLED. In its normal working state, the unit will
cycle its display.

The performance category can only be determined by the unit while in contact with
the platform. The unit will not show the performance category until the mobile path
is registered with the platform when it will retrieve the performance grade.
