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.

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.

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
