Summary Alarm Contacts; Figure 6-2. Summary Alarm Contacts - Eaton Powerware 9315 Operation Manual

Using Features and Options

6.2 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 6-2).
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.
Contacts should not be operated in excess of 30 Vac or 42.4V peak AC or DC @ 1A maximum.
