Summary Alarm Contacts

Two summary alarm 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 panel (see Figure 19).
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 alarm
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 30 VAC or 42.4V peak AC or DC
@ 1A maximum.
