D-Wire Sensors
The NetGuardian AAR supports up to 16 daisy-chained D-Wire sensors via its D-Wire input. Sensors connected to
the NetGuardian AAR will appear on the web interface. The background color of the ROM field informs the user of the
sensor's configuration state.
Also the NetGuardian AAR's first D-Wire sensor used to monitor the internal temperature. The internal temperature
sensor measures a range of -40° F to 180° F (-40° C to 82.2° C) within an accuracy of about ± 2°.
Basic configuration for the NetGuardian AAR's D-Wire temperature sensors can be accomplished from the
Provisioning > Sensors menu. From this screen, you can configure D-Wire sensors, select notification devices,
and set thresholds.

Basic Sensor Configuration
ID Sensor ID number.
ROM ID
The ID number found on the sticker of the temperature sensor node. Your
NetGuardian AAR will automatically detect the sensor ID when you plug a sensor into
the unit. The color of the sensor ID field will tell you the status of the connected
sensor.
Green - The sensor is connected and properly configured.
Yellow - The sensor is connected but has not yet been configured (fill in your
configuration fields and click Save to configure the sensor).
Red - The sensor is not detected and configured (i.e. a previous configured sensor is
no longer connected).
Blue - The sensor is not supported by the NetGuardian AAR.
To reconfigure or disable the Sensor ID, simply delete any data in this field and click
Save .
The unit will refresh the sensor ID on that channel.

The amount (in native units) that the channel needs to go above or below a threshold
in order to cause an alarm.
Qual Time (Qualification
Time)
The length of time that must pass, without interruption, in order for the condition to be
