Unpacking and Installation
Powering the Sensor from Power over Ethernet (PoE)
For All Airnet Models
The Airnet II can be powered from a Power over Ethernet Router that conforms to IEEE
802.3af. A shielded CAT5 cable must be used or a local ground connected to the sensor
for proper operation when using PoE.
The Airnet II 510s and 510s XR is provided with a ruggedized Ethernet cover.
provides instructions for installing the RJ45 Data Connector.
Connecting the Power Supply
After the Airnet II particle sensor has been physically installed with its bracket, connect
the sensor to an appropriate power source.
After the supply cable is connected, the sensor’s Status LED should illuminate
indicating that the unit is receiving power.
If the LED does not illuminate, test the power source and the power supply. If the
power source and power supply are all right, the unit may be faulty.
The Airnet II also has the capability of being powered through Power over Ethernet.
This requires the use of an internet hub designed to operate with such systems. As well
as the use of a CAT5 shielded cable or grounding the Airnet II particle sensor locally.
Connecting the Sample and Vacuum Tubing
The plumbing connections are the following:
Sample inlet
The sample inlet can be used with the sampling probe alone or with
tubing and the sampling probe.
NOTE:
Ensure that the Airnet II particle sensor’s sampling probe is
pointed into the airflow to be monitored.
House vacuum
source
The Airnet II 301, 501, 501A, 510, and 510 XR (Polycarbonate
enclosure version) particle sensor has a barbed vacuum fitting for
connection of 1/4 ID tubing.
The Airnet II particle sensor 510s, and 510s XR (stainless steel
enclosure version) has a push-in fitting for connection of 8 mm OD
tubing.

The vacuum source should be
•
> 15 inches of Hg for 510/510XR and 510s/510s XR (> 410 mBar
below atm pressure)
•
> 11 inches Hg for 301 and 501/501A units. (> 375 mBar below atm
pressure)
