42.6 Alarms
The UPS is equipped with intelligent internal diagnostics that provide power supply
alarm signals. The service provider can monitor these signals in order to isolate
problems and take corrective action. The alarms are as follows:
• AC Fail: There is insufficient ac supply line voltage to maintain battery charge.
This alarm is only set when the batteries are discharging to avoid nuisance alarms
and clears when the battery begins receiving a consistent charge.
• Replace Battery: The battery failed a periodic test. It should be replaced because
system availability has been compromised (BATTFAIL).
• Missing Battery: The battery is disconnected. The load will not be supported if
the commercial power fails (BATTMISS).
• Low Battery: The battery has been reduced to the point that roughly 20% of the
available runtime is available (BATTLOW).
• Audible alarm: You can enable the audible alarm using the switch located above
the 5-position IDC alarm connectors inside the unit.
When enabled, the audible alarm gives a low battery warning of four short beeps
once an hour if the battery string voltage reaches 46.8 V ac. An externally accessible
silence alarm button is located beneath the status LEDs on the front panel. Press and
hold down the button once for 0.5 s to silence the audible alarm for 24 h. A second
silence alarm button is located inside the unit, directly below the internal status
LEDs. For more information about alarms, consult the manufacturer’s
documentation accompanying the unit.
You can install one string of four batteries or two strings of eight batteries in the UPS.
Alcatel-Lucent recommends installing both strings. If only one string of backup
batteries are installed, a battery missing alarm is sent to the ONT.
