5.1.3 Permanent Loss of Communication Between MASTER and SLAVES
in a Daisy Chain Operational Mode
The radio link in Daisy Chain operational mode can be disrupted permanently because of the following reasons:
MASTER or SLAVE units have not yet established radio link communication between them
MASTER or SLAVE units have established radio link communication between them, but the communication is still
faulty
If the radio link between MASTER and SLAVE units is disrupted for a period longer than 15 seconds:
The healthy units will display a
MAGENTA
LED on the SYSTEM INDICATOR/OPERATOR INTERFACE and all units will
immediately transition to FLASHING AMBER condition
The faulty unit will display a
RED
LED RADIO ERROR or WRONG CHANNEL SELECTED fault on the OPERATOR
INTERFACE and the unit will immediately transition to FLASHING AMBER condition
