Connect External Alarm Indicators and Auxiliary Power���

Alarms can be generated on adjunct equipment, sent to the media server, and recorded and reported as "external alarms." A typical major alarm input is from an Uninterruptible Power Supply (UPS).

The media server provides a relay contact that can operate a customer-provided alarm, such as a light or bell. The circuitry and power source are customer-provided. The alarm device must not exceed a rating of more than 100 volts at 0.75 amperes.

1. Connect 1 major and 1 minor alarm input pair to the trunk/auxiliary field from the AUX connector. See Alarm Inputs at AUX Connector.
2. Connect an external alarm output through pins 48 and 23 of the AUX connector. See Alarm Output at AUX Connector.
3. Note which device connects to which alarm and give this information to your Avaya representative for troubleshooting purposes.
4. Connect emergency transfer power and auxiliary power as shown in Emergency Transfer and Auxiliary Power. Auxiliary power includes power to an attendant console or adjunct device.
