A Bell Controller checks-in to OneVue hourly and you can optionally initiate a manual check-in. During each check-in to OneVue, a bell controller downloads pending bell schedule updates, transmits its current status and event history, and also connects to its NTP time source to synchronize its time.
Press and quickly release its check-in button
(up arrow).-
The bell controller emits a series of audio beeps indicating its connection sequence.
