Connecting external alarm indicators and auxiliary power
Alarms can be generated on adjunct equipment, sent to the server, and recorded and reported
as “external alarms.” A typical major alarm
input is from an uninterruptible power supply (UPS).
The media gateway 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 device connected
to the alarm leads must not exceed a rating of 30Vac RMS or 60Vdc max, at 0.75A max. The
customer provided alarm circuit must also meet the requirements for an SELV (Safety extra-low
voltage) circuit; the alarm circuit power source must be a power supply or transformer meeting
the UL 60950 SELV, Level 3, or Level 5 requirements. See
