Connect
To add the TD52 to your Verkade
Command account, go to: command.verkada.com/add-
device Enter the serial number printed
on the back of the device, the packaging, or the order number.
If you would like to update and configure TD52 before mounting it, connect the
device to your network using the Ethernet port located in the cable bay on the
back of the device.
Mounting 1/7
The flush mount plate has holes configured for the following mounting
conditions:
A/B Legacy intercom back box Direct wall mounting
C 4-gang junction box mounting
Use the corresponding holes to mount to an existing intercom back box (A/B
) or 4-gang junction box (C).
Direct wall mounting
To mount directly to a wall, use the mount plate as a template to mark
mounting holes (B) and the center cutout.
Use the marks to drill pilot holes for the mount plate. For direct mounting,
drill 3mm pilot holes. When using wall anchors, drill 6mm pilot holes.
Use the
supplied screws to install the mount plate onto the wall. Ensure that the
labels (A, B, C) on the mount plate are facing away from the wall.
Please note: The supplied screws are intended to cover most possible
install cases. Be sure to use the best screws for your specific job.
Mounting 2/7
Route the building-side cable through the hole in the center of the mount
plate.
On the rear of the device, loosen the four T10 Torn Security screws on the cable bay door to access the ethernet and I/O ports.
Mounting 3/7
Attach grommet punch to the RJ-45 cable.
Insert the RJ-45 ethernet cable through the right grommet using the included grommet punch and pass through the cable bay door.
Remove the grommet punch and Insert the RJ-45 ethernet cable into the PoE port.
Mounting 4/7
If the installation requires the use of the I/O terminal block, insert I/O
wires through the left grommet and pass through the cable bay door. Remove the
I/O terminal block with a flat head screwdriver or the end of the grommet
punch tool for easier installation.
Attach I/O wires according to the pins below.
| Pin 1 | Pin 2 | Pin 3 | Pin 4 | Pin 5 | Pin 6 | Pin 7 | Pin 8 | Pin 9 | Pin 10 |
|---|---|---|---|---|---|---|---|---|---|
| NO | COM | NC | GND | B | A | 12V | GND | IN 1 | IN 2 |
| Output | RS-485 | Input |
Mounting 5/7
Plug in the RJ-45 and the I/O terminal block. 
Return the grommets to the cable bay door. Make sure the grommet is installed in the right direction for proper sealing.
Please note: The tail of the grommet should be facing away from the device
after installation for proper sealing.
Secure the cable bay doors by tightening the four T10 Torx Security screws at each corner.
Mounting 6/7
On the bottom edge of the device, loosen the two T10 Torx Security screws and
remove the faceplate.
Attach the device to the mount plate to the wall using the four provided M4
machine screws.
Mounting 7/7
Reattach the faceplate by engaging the hooks at the top. Swing the faceplate
down into position. 
Tighten the two T10 Torx Security screws on the bottom edge of the device.
Wiring Instruction
Reader
The TD52 is rated to power Verkade readers at 12V and 250mA via the (+) and
(-) connection. It is recommended that the drain wire be connected to earth
ground at the reader side. Note: 12V power should not to be used to power
other peripheral devices, as it has latch-off current limiting. 
Inputs
The TD52 has two general purpose dry inputs. Devices commonly connected to
these dry contacts include Door Position Indicator (DPI), Request to Exit
(REX), and external call triggers. Both inputs are expected to be NORMALLY
OPEN (NO). For each input, one wire should be connected to the IN pin, and
the other to the GND pin. All associated events will be logged in Command.
Note: When configuring the TD52 as an single door controller, the DPI
should be connected to IN 1, while the REX should be connected to IN
2.
Output
The TD52 has one dry form C relay output, which can be configured as an access
controller by connecting an access power controller to the output terminal as
detailed below. The output relay can also be used as a general purpose output.
For fail safe locks, + should be connected to NC to be locked by default. For
fail secure locks, + should be connected to NO to be locked by default.
Note: To maintain UL294 compliance all devices connected to TD52 devices connect to TD-52HW should be UL 294 and ULC 60839-11-1 Listed
