10.1 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. You should use twisted-pair wires
for each alarm input and common.
The building alarms can be programmed to display the alarm functional name.
10.2 General Purpose Relay Contact
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.
C A U T I O N
Contacts should not be operated in excess of 120 Vac @ 5A maximum.
