The device’s indicator lights present sensor alarms and faults.
In alarm and fault situations, the buzzer sounds an alarm and the relays are switched to the
alarm position.
The relays are of the failsafe type, which means that they also enter the alarm state when
operating power is lost.
The operation of the product is described in more detail in the section Operation.
