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.
