Note

The SmartSensor Advance has built-in surge protection and so there is no need to

use a pole-mount box for surge protection on the sensor side of the cable. However,

in the main trac cabinet. If you choose not to use surge protection in your main

When a Click 222 is present, the power and RS-485 serial connections on the T-bus and

faceplate are protected from surges on the incoming SmartSensor 6-conductor cables.

e Click 222 faceplate has four activity indicator LEDs:

 PWR – Indicates that the device has power.
