This article provides instructions for setting up, installing, using, and maintaining the ST2029 PoE+ Door Central, which is specifically designed to be used in conjunction with the Steplock Access ST2020 Intercom.
NOTE: Please note that there are two versions of the ST2029 – PoE+ and LTE. This article only applies to the PoE+ version. For information on the LTE version, please refer to the following support article.
J1 – ST2020 Intercom
J4 – Relay Output
J5 – Lock Output
J6 – Strapping pin
J7 – PoE+ / Network
J8 – Open button
J9 – AC/DC External Power Source
J10 – Power Output
J11 – Strapping pin
The ST20290 PCB board have 2 status LED-indicators;
The ST2029 can be powered using a PoE+ IEEE802.3at switch (30W per port) or the Steplock Access STEP Power 4p PoE+ with built-in power backup. This port also connects the device to the Steplock Cloud network.
NOTE: See “3.7.1 Powering ST2029 using PoE+” for more information.
NOTE: For more information on STEP Power 4p PoE+ please click here.
An alternative to powering the ST2029 using PoE+ is using “J9 – AC/DC” for external power, 12v – 28v.
There are two options for changing output voltage on the ST2029 using strapping pins.
NOTE: If the ST2029 is powered by external 12v power, then you cannot set either strapping pins to 24v, since the PCB-board is equipped with step-down regulators (24v to 12v) only.
All measurements are ST2029 Door Central only (without intercom).
60mA at 24v ST2029-POE+
100mA at 12v ST2029-POE+
The pins on the “Lock-relay” are labelled “+ – +”.
This is equivalent to “NO+ | GND | NC+”. In other words if you have a fail secure* electronic lock configuration, you connect + on the left pin (NO+).
If you have a fail safe* configuration you connect + on the right pin (NC+).
NOTE: *Fail Secure: If there is no power, the lock will remain closed.
*Fail Safe: If there is power the lock will remain closed. In the event of a power failure the lock will remain open.
“J4 – Relay Output” is a potential free relay and follows the “J5 – Lock output”, meaning if the “J5 – Lock-output” is triggered, then the “J4 – Relay output” will also be triggered with a 1 second delay.
“J10 – Power output” is for powering external accessories devices.
NOTE: Not intended for cascading power connections. You have only 30w available when powering the unit using PoE+.
When “J8 – Open button input” is triggered, it simultaneously triggers the
“J4 – Relay output” and “J5 – Lock output”.
“J1 – ST2020 Intercom” delivers power, communication (RS485) and ethernet to the ST2020 intercom.
NOTE: The RJ45 Cable is split at the intercom end.
”WARNING: Only power on the ST2029 once you have carefully read and understood these instructions, and confirmed that the unit is properly connected. Failure to follow these instructions may result in damage to the product and render it inoperable.”
Prior to installing the ST2029, make sure that you done the following tasks in StepCloud:
NOTE: If you have not done this, and you do not know how to do the above mentioned steps, just click on the respective links below:
The following cables are required for a standard installation and should be installed in the door location before installation begins.
The following tools will be required for the installation:
”NOTE: This guide assumes that all necessary cables have been installed between the Intercom location (Point A), the ST2029 PoE+ Door Central location (Point B), and the PoE+ enabled Switch location (Point C). The cables have been properly terminated and are ready to be connected. The CAT 6 cable must not be longer than 100 metres between each point.”
The ST2029 should be installed in close proximity to the door. A common location to mount the ST2029 is above the door as this is where the majority of electronic lock, exit button, and door automation connections are typically found.
For fail secure configuration connect “+” on the left pin on J5 – Lock Output and “-” on the middle pin (“-”) of the J5 – Lock Output as illustrated in Fig.11.
For fail safe configuration connect “+” to the right pin on J5 – Lock Output and “-” on the middle pin (“-”) of the J5 – Lock Output as illustrated in Fig.12.
NOTE: If electronic locks other than Steplock are being used, it is recommended to install a protection diode (e.g. 1n4004) between the electronic lock and the output. The diode should be placed as close to the electronic lock as possible.
Connecting the exit/open button to the ST2029 is straightforward. Connect pin A and pin B to your exit button. If your exit/open button requires 12V, it can be powered separately using the J10 – Power output. In the following example, we have used a touchless exit button which requires 12V.
NOTE: In this example “Left pin” refers to the pin on the left side with the PCB board oriented so that the “Power Out” is upside down. See fig.15 for clarification.
NOTE: Take care to measure your total power budget when you are using J10 – Power Output. PoE+ = 30w per port.
NOTE: These instructions are only for connecting the ST2020 intercom to the ST2029 Door Central PoE+. For detailed instructions on how to install and set up the ST2020 intercom, please refer to the following article.
ST2029 connects to the ST2020 Intercom using a CAT 6 (T568B) cable.
There are two revisions for the cable that comes with the ST2020 intercom.
Please refer to Fig. 17 for the two revisions.
The CAT-cable between the ST2029 and the ST2020 Intercom is split at the intercom side.
IMPORTANT: Please be aware that the connection of the RS485 A and B on the ST2029 has been reversed. To connect the ST2029, connect “Blue/White” to RS485B and “Blue” to RS485A on the intercom side. See the illustration below.
CAT 6 T568B REV 1:
Brown/White = 12V
Brown = PWR_GND
Blue = RS485A
Blue/White = RS485B
CAT 6 T568B REV 2:
Red = 12V
Black = PWR_GND
Brown = RS485A
Brown/White = RS485B
CAT 6 T568B REV 3:
Red = 12V
Black = PWR_GND
Blue = RS485A
Blue/White = RS485B
NOTE: This guide assumes that a functional network infrastructure with a PoE+ enabled switch with an adequate power budget is already in place. Ensure that the PoE+ IEEE 802.3at standard is being used and that the switch port is properly configured to deliver a minimum of 24V
WARNING: Carefully check the strapping pins on J6 and J11 before powering the ST2029 to ensure that the correct voltage is being supplied to the units connected to the ST2029.
When planning your power usage, don’t forget to consider additional factors such as the electronic lock and whether you’ll be using the J10 output. It’s crucial to calculate your total power budget to ensure that you have enough voltage and amperage to meet your needs. Using PoE+ you have only 30w available.
Connect the CAT 6 cable to the input J7 – PoE+ In. You have now powered the ST2029, and subsequently any other connected units.
NOTE: The ST2020 Intercom needs internet connection to initiate a call. If you have a ST2029 with LTE capabilities it makes sense to have the Intercom connected to a power source with power backup. The STEP Power comes with built in power backup. For a full installation guide for STEP Power, please refer to the following article.
To connect the STEP Power 4p PoE+, insert the CAT 6 cable into J7 – PoE+ In.
There is also an option for powering the ST2029 with an external power source.
NOTE: In this example “Left pin” refers to the pin on the left side with the PCB board oriented so that the “Power Out” is upside down. See fig.22 for clarification.
Simply connect “+” to the Right pin of J9 12-28V AC/DC and “-” to the Left pin.
NOTE: You can set +/- as you wish. Input is AC/DC. Input voltage is 12 – 28V.
WARNING: If you have connected other units to the ST2029 then check the strapping pins on J6 and J11 before powering the ST2029, to ensure that you have correct voltage to the units connected to the ST2029.
Also take care to measure the total power budget. The Door central uses 60mA at 24v and 100mA at 12v, and the intercom uses 1000mA.
When planning your power usage, don’t forget to consider additional factors such as the electronic lock and whether you’ll be using the J10 output.
It’s crucial to calculate your total power budget to ensure that you have enough voltage and amperage to meet your needs.
It is recommended to use a DC balanced ripple-free power supply with a minimum capacity of 2 amperes. Please note that the total power consumption of connected products may vary, so it’s important to check this carefully before selecting the power supply.”
You can power other units from the J10 – Power Output using either 12V or 24V.
You must adhere to the total power budget of the ST2029.
