How to Install the ISONAS PureIP Reader-controller 20
2.2.3: WIRING THE REX/AUX INPUT
The PureIP RC s REX / AUX input expects a momentary
closure. You can generate this signal with a pushbutton,
infrared motion detector, or other simple device.
The host computer configures the reader to know if the
input’s action is treated as a REX event or an AUX event.
Typically the REX is placed adjacent to the door so that
people can press the button and let themselves out the
door without setting off the alarm. When pressed, this
button tells the ISONAS Reader-controller
that that someone wishes to pass
through the door, and the latch releases.
The reader could be configured to create
an AUX event. An example usage of the
AUX input is being connected to a panic
button under a cashier’s desk. The AUX
event could then generate a system alert
message.
You must wire the switch through the
ISONAS Reader-controller.
(See Figure 8) First, connect one
terminal of the momentary switch to the
Reader's green wire. Then, connect the
switch's other terminal to the Reader's
common ground wire (brown).
