Connecting the Failsafe Alarm Relay

The failsafe relay on the Control Module (CM) 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.
