Remote Alarm Contacts
The DC-UPS includes external alarm contacts to provide the ability to remotely monitor the
status of the unit. These alarms will indicate either an AC Fail or a Battery Test Fail
condition. Both normally open and normally closed contacts are provided to suite the user’s
external monitoring circuitry. The alarm contacts have a 2 Amp rating. The NO and NC
contacts will change state when an alarm condition occurs. The connector state pin-outs are
printed on the System Controller Card.
Alarm Access and Connection
The alarm connectors are located on the front edge of the System Controller Card and are
accessible via an RJ45 connector on the front cover. The Alarm Contact connector pinouts
are shown in Figure 2
