Sensor replacement and reuse scenarios Instructions

Replace a sensor with an NS Series Sensor

Note: 

Replacing a TE-6xxx Series

Sensor is recommended over reusing

the sensor because it provides a

usable port at the sensor location for

commissioning.

Sensor Replacement Scenario
Descriptions

TE-6xxx series sensor connected to
VMA Controller

To replace a TE-6xxx Series Sensor with a

functionally equivalent NS Series Network Sensor,

follow the instructions in the 

Replacing a TE-6xxx

series sensor

 section.

To reuse a TE-6xxx Series Sensor connected to

a VMA controller, follow the instructions in the

Reusing a TE-6xxx series sensor

 section.

Replacing the sensor with an NS Series Network

Sensor is preferred to reusing the TE-6xxx Series

Sensor because the NS sensor allows for easier

controller commissioning. Be sure to use an NS

sensor with similar dimensions as the existing

sensor in order to match the original sensor

installation.

Note: 

If temporary occupancy is required for

the application on the TE-67xx and TE-68xx

Series Sensors, set the sensor's LED mode to

LED ON

 (the DIP switch positions on the back

of the sensor are down, up, and down). This

setting only applies to single and no setpoint

controller models (not dual setpoint controller

models). The VMA1832 does not support the

LED OFF

 mode and the pushbutton will not

function in that configuration.

Refer to the 

NS Series Network Sensors Product

Bulletin (LIT-12011574)

 for a complete list of available

NS Series Network Sensors.

Note: 

In each of the following procedures

that include the use of the Commissioning

Converter (BTCVT), note the following: The

Mobile Access Portal (MAP) Gateway serves

as a replacement for the BTCVT, which is no

longer available for purchase, but continues to

be supported on select controllers. CCT auto-

detects when BTCVT can be used or not, based

on the controller model and the corresponding

CCT Release mode.
• BTCVT can be used with controllers that

contain CCT Release mode 10.2 or earlier

firmware.

Metasys

®

 controllers from Release 9.0 or

earlier support BTCVT.

• BTCVT cannot be used with controllers that

contain CCT Release mode 10.4.
