2.4 Information Management Options, continued
Intelligent Interface Device (optional)
The Intelligent Interface Device (IID) option is available either as a replacement
of the Standard Interface Device (SID) or as a desktop unit for remotely accessing
the unit (up to 2000 ft.). The desktop unit comes with an optional modem for
accessing the UPS information via a telephone line. The IID front panel provides
precise UPS information and guides you through the various menu options which
include Ambient Battery Temperature, Input Voltage and Current, Line Frequency,
Output Voltage and Current, Power in Watts, Power Factor, Battery Voltage, Charger
Status, and more. The History Log maintains an on-going record of UPS alarms and
power anomalies by time, date and type of occurrence. Whenever a UPS alarm
condition occurs, such as Line Failure, Low Battery Warning, Low Battery Shutdown
or Service, it is displayed by the front panel indicators and recorded in the History
Log.
External Modem (option available on 60Hz models only)
The optional modem that comes with the desktop IID provides access to the unit
via a phone line. Service personal can dial up the unit to remotely monitor, control,
and calibrate the unit. On specified alarm conditions, the unit can dial an emergency
number to notify the system manager via modem of the alarm. The modem option
may also be used to page service personnel on critical alarm conditions.
For further information on operation and installation of the IID, please
refer to its operator’s manual “Information Management Using the
Intelligent Interface Device.”
