Using Features

11.1 General

The many standard features of your UPS system provide consistent, economical,
and dependable power protection. In addition, you can add available options to
enhance the performance of your system. This chapter provides descriptions of
the features and options introduced earlier in this manual, but not covered in other
chapters. Refer to drawings 164201491---2 and 164201491---8 in Appendix A for
location of the customer interface panel and terminals and for terminal wiring
information.

11.2 Building Alarm Monitoring

This standard feature lets you connect the UPS to your building alarms, such as
smoke detectors or overtemperature alarms. The customer interface terminals for
external connections are located inside the UPS.
Regardless of how you assign the building alarms, they display as Building Alarm
1, Building Alarm 2, Building Alarm 3, etc., on the LCD screen of the Monitor Panel.
You should use twisted pair wires for each alarm input and common.

11.3 General Purpose Relay Contacts

Two general purpose relay contacts are provided as a standard feature on the UPS.
The alarm contacts (one notice and one alarm) are located inside the UPS on the
customer interface terminal board.
You can specify that each contact be either normally closed (NC) or normally open
(NO). If the state of the contact changes from the state you specify as normal, an
signal is issued. You can connect these contacts to equipment at your facility
(such as a light or an alarm bell) to let you know when an alarm is active on the
UPS. This feature is useful if the UPS is located in a remote area where the UPS
alarm horn may not be heard immediately.
CAUTION:
Contacts should not be operated in excess of 120 VAC @ 5A maximum.
