Description
NTP
Failed to synchronize its time with an NTP time source during its last network connection.
It may not have the correct time, which may impact the accuracy of its bell schedules.
SCHD
Downloading a bell schedule.
A bell controller 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. Also, pending
schedule updates are downloaded to the device during its hourly check-in.
Relays do not operate during this mode. OneVue prevents schedule downloads to take place
within 5 minutes of a bell ring to avoid interfering with the ringing of bells.
No Signal
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 it is not within range of wireless
access point or the wireless signal strength is not adequate for normal operation.
If powered by AC or Power over Ethernet (PoE), the yellow LED indicator flashes during this
state.
Signal OK
