How to Install the ISONAS IP-Enabled Reader-controller 23
2.2.5: WIRING THE DOOR SENSE
Connecting the ISONAS Reader-controller to a door sensor allows our Crystal
software to determine whether that door is physically open. Then the Crystal
software can create alarms based on the door’s state.
This wiring task is similar to wiring the REX or AUX
buttons.
First, connect one terminal of the door sensor to the
Reader's blue wire. Then connect the door sensor's
other terminal to the Reader's common ground wire
(black).
Figure 10 shows how to wire the door sensor.

About the Door Sense
The door sense is a
normally closed input. No
action is taken until the
input is opened.
IMPORTANT: If There's No
Door Sense Switch
If you choose NOT to install a
door sense switch, then you
must permanently ground
the door sense input (blue
wire) to the reader’s Black
wire, so the system will not
see the door as "open."
