Ratings |
3 VDC Relay operation Normally Closed (NC) & Normally Open (NO) contacts are rated at: resistive load: 8A at 250VAC / 30 VDC | inductive load: 3.5A at 250VAC / 30 VDC |
Power |
AC power: 5V DC USB Mini B (5 pin) connector interface, 5 ft (1.5 m) cable | Input: 100-240 VAC, 50/60 Hz, 0.4A | Output: 5V DC, 1.0A max. Optional power extension cable: USB power cable 6.5 feet (2 m), Mini B (5 pin) M and Mini B (5 pin) F connector Power over Ethernet (PoE): compliant with IEEE 802.3af standard and compatible with 802.3at standard Battery backup: estimated up to a maximum of 24 hours operating on battery backup power only. Requires two AA Lithium 1.5V batteries; Energizer® L91 Ultimate Lithium batteries recommended. |
IP Network Communication |
Network LAN port: RJ-45 Ethernet, 10/100 Mbps, 802.3 Ethernet Network Communication Protocols: Hypertext Transfer Protocol Secure (HTTPS)/TLS IP Addressing: Dynamic Host Configuration Protocol (DHCP), static IP addressing Data Packet Size: typically less than 5 kilobytes (kB) |
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 schedule updates, transmits operating status and event history to OneVue, and synchronizes its time with an NTP time source. Unresponsive Timeout: 3 hours. Set to an alarm when no connection to OneVue detected for 3 consecutive hours. 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. |
