Relays are of dry contact types. In normal operation the "Break Out On" relay is open and it closes
during a break. In case the power is lost or turned off the "Break Out On" relay remains open
(disabled). "Break Out Off" works in the opposite way.
”Alarm
Out Off" is normally closed. It opens in case the built-in self-diagnostics detects a failure.
If power is lost or turned off the "Alarm Out Off" is OPEN. "Alarm Out On" works in the opposite
way.
