5 – Mounting and Installation 

A typical installation will involve mounting the wall plate into a pre mounted single-gang or larger wall box, standard 

drywall bracket or mud ring. Before starting, make sure the wall box where the unBT2A is to be installed is pre-wired with 
a suitable CAT5e or better cable back to the unBT2A-EXP break out box. 

 
With the unBT2A-EXP powered off, attach the CAT-5e cable from the unBT2A port of the unBT2A-EXP to the RJ45 on the 

unBT2A. Apply power by plugging in the 24V DC power supply to the DC power input on the unBT2A-EXT. The power LED 
on the unBT2A-EXT should illuminate green. Additionally, the unBT2A wall plate should also start up and once ready to 

operate, the front panel power status indicator should also be illuminated green. 
 

*Note: 

Upon power up, the power LED will initially light red and then change to green if the wall plate boots successfully. 

If the LED remains on solid red, this indicates a device failure. If power cycling the BT2A does not correct this problem, 
contact Attero Tech technical support. 

 
With the cable attached, carefully place unBT2A into the wall box taking care to not trap the cabling. Once fully in place, 

secure it with the screws provided. Once the unit is secured in the wall box, fit the Decora plate over the front of the unit 
and secure it with the screws provided with it. It is recommended to not over-tighten the screws that attach the included 

Decora wall plate to prevent cracking it.
