By default, the relays are normally de‐energized and will go energized
when events occur. However the relays can be configured for "fail‐
safe" or normally‐energized. If so, events will drive them to de‐
energized.
If relays are set to normally closed, the relay is powered up with the
controller and the device linked to the relay is functioning. The relay
will shut down when the associated event is activated.
If the relay is set to normally open, the relay will remain off when the
controller is powered up and the device connected to the relay will
only be activated when the associated event is activated.
