Alarms can be generated on adjunct equipment, sent to the DEFINITY System,
and recorded and reported as “external alarms.” A typical major alarm
input
is
from an Uninterruptible Power Supply (UPS).
1. Connect 1 major and 1 minor alarm
input
pair to the trunk/auxiliary field
from the AUX connector. See Table 5-5
.
Alarm Output
The system 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 30 VAC RMS
or 60 VDC at 0.75 Amp.
1. Connect an external alarm
output
through pins 48 and 23 of the AUX
connector. See Tab le 5- 6

2. Note which device connects to which alarm and give this information to
your Lucent Technologies representative for troubleshooting purposes.
