10.1Building Alarm Monitoring

This standard feature lets you connect the UPS to building alarms, such as smoke detectors or overtemperature alarms. The customer interface terminals for external connections are located inside the UPS.

Regardless of how you assign the building alarms, the default is to display the alarms as Building Alarm 1, Building Alarm 2, Building Alarm 3, and so on, on the UPS control panel. Use twisted-pair wires for each alarm input and common.

10.2General Purpose Relay Contacts

Two general purpose relay 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 terminal board.

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, a signal 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 horn may not be heard immediately.

C A U T I O N

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