Operation of the System
SUPREMATouch 39 US
Normally energised/Normally de-energised
Field type: Selection
Set the operating mode for the selected relay output:
-
Normally energised [closed circuit]:
The relay coil is energised in the no alarm status and is de-energised in the alarm status.
The output delivers in the set-condition [Alarm, Failure] a LOW-Signal, this is called a connect-
ed relay is not energised. [The Normally energised principle]
-
Normally de-energised [open circuit]:
The relay coil is de-energised in the no alarm status and is energised in the alarm status.
The output delivers in the set-condition [Alarm, Failure] a HIGH-Signal, this is called a connect-
ed relay is energised. [The Normally de-energised principle]

Field type: Check box
In this field, select the alarms that will cause the selected relay output to be activated, for the input
shown in the “channel” column in the specific line.
Fail
