Table 3-3 – Information Display Status and Alarm Definitions (continued)
Alarm Definition
STATUS: BIND ALARM
System 1 only. The “BIND ALARM” can be generated by either of the
following conditions:
• One or more controllers are not bound correctly. A “SYS COMM”
alarm will accompany the “BIND ALARM”.
• Two or more controllers are bound to the same connected
equipment (beacon or marker tier). A “SYS COMM” alarm will
not
accompany the “BIND ALARM” in this instance. The most noticeable
symptom is a beacon that is not flashing in “Sync.” with the rest of the
system. This alarm can be corrected by unbinding then binding the
tower. “LOCAL TOWER CONFIG” (this section) provides complete
instructions for the binding/unbinding procedure.
STATUS: TWR SYNC
System 1 only. One or more subordinate units have not synchronized
with System 1 for a period of one hour or more.
STATUS: GPS ALARM
System 1 only. GPS synchronization has not occurred for a period of
one hour or more. Possible causes are:
• GPS antenna is obstructed or does not have a clear view of the sky.
• GPS antenna failure. Check GPS status LEDs located on PCB 3 for
“short” or “open” indication.
• GPS receiver fault
• PCB 3 failure.
STATUS: IR ALARM The connected flashhead is exhibiting an Infrared alarm.
STATUS: IR N/A Infrared is not available or supported by the connected flashhead.
STATUS: PD ALARM
System 1 only. More than 19 hours have passed since the system
has changed modes via the photodiode input.
STATUS: POWER FAIL
System 1 only. Primary input power failure. PCB 1 is operating on
battery backup to provide alarm notification.
STATUS: LOW DC
Output voltage (60 VDC) to the connected flashhead and marker tier
(if present) is low.
STATUS: LI TEST MODE
Systems 2-6 only. Indicates that System 1 is conducting a Lighting
Inspection test on the system.
