Connecting the Failsafe Alarm Relay

The failsafe relay can be configured to latch based on alarm conditions. The NO (Normally Open) contact is closed
when the unit is powered and there are no active alarms. If the device is not powered or if an active alarm is
configured, the relay opens the NO contact and closes the NC (Normally Closed) contact.
NOTE
Control of the failsafe relay output is configurable through ROX II. One common application for this
relay is to signal an alarm if a power failure occurs. For more information, refer to the ROX II User
Guide for the RUGGEDCOM RX1501.
The following shows the proper relay connections.
