How to Install the ISONAS PureIP Reader-controller 21
2.2.5: WIRING THE DOOR SENSE
Connecting the ISONAS Reader-controller to a door sensor allows the host software to determine
whether that door is physically open. Then the host system can create alarms based on the door’s
state. This wiring task is similar to wiring the REX / AUX
input.
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
(brown).
Figure 9 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 Brown
wire, so the system will not
see the door as "open."
