Connecting the Failsafe 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.
