900-R Installation Manual
5.2 Output Wiring
There are 3 outputs. These outputs are triggered by the 900-PRIME’s inputs. In a typical
access control setup, OUT1 is used for the door strike.
All output contacts can be selectable as normally open or normally closed by jumpers S6-S8.
The following diagram is an example of a typical wiring of DC and AC source application to
outputs including an example of the NO/NC selection by jumper settings.
Factory default output settings are Normally Open.
Use minimum 18AWG (Belden 9740 or equivalent) for the connection.
