Status Indication
The Reader Expander includes comprehensive diagnostic indicators that can aid the installer in diagnosing faults
and conditions. In some cases an indicator may have multiple meanings depending on the status indicator
display at the time.
8.1
Status Indicator
The Status Indicator is located in the centre of the PCB and indicates the status of the Protege Reader
Expander. If the Protege Reader Expander is operating normally the LED will indicate this by FLASHING at 1
second intervals. FLASHING rapidly at 250ms intervals indicates that the Reader Expander is attempting to
register with the system controller, or that communication has failed and the Reader Expander is retrying the
request.
i
When the fault indicator is ON the status indicator will show an error code. Refer to the section on
Error Code Display for more information.
8.2
Fault Indicator
The fault indicator LED is identified by the text 'FAULT' and is located in the centre of the PCB. When the fault
indicator is FLASHING the Reader Expander is operating in firmware update mode, or there is no firmware
loaded. The fault indicator when ON indicates that an error has occurred while trying to register with the system
controller. The status indicator will flash a number of times indicating an error code. Refer to the section on Error
Code Display for more information.
8.3
Charge/Test Indicator
The charge and test indicator serves two functions; it will indicate that a Battery Test is in progress, and that
Battery Charging is being performed. When AC is present the battery charging current will be indicated by a
varying intensity level on this indicator. This indicator will be ON when a battery test is in progress by illuminating
brightly for 30 seconds every 10 minutes.
This indicator is identified by the text CHARGE/TEST. This indicator does not function when AC is not present.
For more information, refer to the section on Battery Backup.
8.4
Auxiliary OK Indicator
Auxiliary voltage is supplied to the AUX+ outputs through the auxiliary fuse. If auxiliary supply is normal the the
AUX OK indicator will be illuminated. If the auxiliary fuse is damaged, the indicator will be off.
8.5
AC OK Indicator
When a valid AC input is provided, the AC OK indicator will illuminate. When the AC is disconnected or has
failed, the indicator will be off.
