Description
NTP
The Bell Controller device is an Alarm state. During its last check-in, the device failed to synchronize its time with a
NTP time source. The device may not have the correct time, which may impact the accuracy of its bell schedules.
SCHD
A schedule is being downloaded to the Bell Controller device.
A device stores a 7-day schedule in its local memory for each of the two relays. Each night after midnight, the 7-
day schedules are downloaded to the device. In addition, any schedule updates are downloaded to the device
during its hourly check-in.
Relays do not operate during this mode. The system prevents schedule downloads to take place within 5 minutes
of a bell ring to avoid schedule downloads interfering with the ringing of bells.
No Signal
The Bell Controller device is an Alarm state. The device has not checked-in to OneVue for more than 3 hours. It's
scheduled to check-in hourly.
For wireless network use, a failed check-in may be due to the device is not within range of its configured wireless
access point or the wireless signal strength is not adequate for normal operation. For PoE or Ethernet use, a failed
check-in may be due to the device gateway could not establish a network connection.
If the device is powered by AC or Power over Ethernet (PoE), the yellow LED indicator flashes during this state.
