Using Features and Options

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 some of the
features and options introduced earlier in this manual. For the customer interface
panel and terminal locations and for terminal wiring information, see:

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. You should use twisted-pair wires
for each alarm input and common.
The building alarms can be programmed to display the alarm functional name.
One general purpose relay contact is provided as a standard feature on the UPS. The
alarm contact is located inside the UPS on the customer interface terminal board.
You can use a normally-closed or normally-open contact. If the state of the contact
changes from the state you specify as normal, a signal is issued. You can connect this
contact 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 horn may not be heard immediately.
Contacts should not be operated in excess of 120 Vac @ 5A maximum.
