Mounting Instructions

Note: The BRD21 should be commissioned onto the Thread network before mounting if access to the BRD21 buttons will be restricted once installed.

What you’ll need

1. Drill or Screwdriver

2. 4 Flat Head Screws

3. Wall Plugs (optional, depending on the material mount is affixed to)
4. Safety and Protective Equipment

Installation

The BRD21 can be mounted easily and securely.

As a wireless networking device, some considerations for placement should be taken to give the best possible range and performance of your Thread networking devices.

Placement and orientation
The BRD21 can be mounted on walls or ceilings. The ideal orientation is vertically on a flat wall, with Power and Ethernet cables facing down. A clearance of 2cm on all sides should be maintained.

The BRD21 should:

1. Not be installed in a cabinet or metal
2. Not be installed behind walls or other obstructions which would interfere with line of sight to other Thread devices on your network.
3. Not be installed low to the ground
4. Be installed in a central location that offers the best coverage for devices in the
   • BRD21 Repeater devices can be added to your Thread network to improve network coverage.
5. Not be installed on rough or uneven surfaces

Installing The Mounting Bracket

• The Mounting Bracket is installed using 2 x #4 Flat Head Screws.
• All safety precautions should be taken by you before installing the mounting bracket.
• When choosing a location for the mounting bracket, ensure final placement of the device is not obstructed.
• Please ensure the mounting bracket is installed with enough clearance for the BRD21 to slide onto the mounting bracket. Final placement of the BRD21 with respect to the
• The mounting bracket can be seen below.

Caution: Do not overtighten screws. Screws must be flush with the mounting bracket. # 4 Flat Head screws only. The mounting bracket should be level and installed flush to the wall or ceiling surface material.

Attaching  BRD21
Once the mounting bracket is correctly installed, and with Ethernet and Power cables connected to the BRD21, slide the BRD21 onto the bracket from left to right to mount.
