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.
