Pin assignment
-
We recommend connecting 'Alarm' 1 to the alarm system and 'Alarm' 2 to
the safety system.
-
Alarms 1 and 2 are getting switched simultaneously by same relay.
-
The relay outputs are potential-free.

In case of a High Oil Mist Alarm, contacts 7 and 8 as well as 15 and 16
are closing
-
In case detector goes into ‘READY’
-Mode, contacts 4 and 5 are closing
