diAl-out on outAge
The INP2 modem has a dial-out circuit with a battery that detects when voltage is lost and dials out to provide outage notification. Additionally, the circuit can be configured to dial out when many other circumstances occur. The Nexus 1262/1272 dials to the EIG Dial-In Server which allows users to be paged or emailed with notification of events. When the modem option card is installed, the meter also includes a gateway port. This allows the meter to act as a master for up to 7 additional meters and dial out on alarm for any of these meters.
diAl-out for other events
The meter will dial out for the following circumstances:
- Limits/Status Change
- Control Output Change
- High Speed Input Change
- Cycling of Control Power
- Waveform Record Capture
- Password Failure on a Call
- CBEMA Power Quality Event Coming into the Modem
- Control Output Change • Meter Communication Failure
