Operation |
Alerts: visual LED and LCD display indicators Stored Schedule Capacity: 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. Check-In Interval: hourly; downloads schedules, transmits operating status and event history to OneVue, and synchronizes its time with NTP time source Relays: two individual relays; each relay can be wired for NO (Normally Open) or NC (Normally Closed) operation Dry Contact Inputs: two individual inputs to activate a non-scheduled event (impromptu bell); connected to an external dry contact closure switch or button On-board clock: synchronizes its time with an NTP time source to ensure bell schedule accuracy; even after power outages and Daylight Saving Time shifts |
Network Communication |
