AD Series Wireless Lock Setup

Learn how to use wireless locks with your Verkada access controller

Updated over a week ago

Verkada access controllers require wired inputs into their cartridges to register events and operate locks. This does not, however, prevent wireless locks from integrating with the AC41/AC42. This article focuses on how to use the wireless lock Schlage AD400 paired with a PIM 400-485.

Note: You cannot use AD Series Wireless Locks and the Verkada AD31 and AD32 readers in the same installation.

Before you begin

You will need the following hardware:

  • AC41/AC42

  • Schlage Utility Software (SUS) cable

  • SUS phone or SUS device with the SUS app installed

  • PIM 400-485

  • AD400 or AD300 lock

Note: Required items vary, depending on the installation. For assistance, please contact your Allegion ESE.

Install and configure the PIM 400-485

The PIM 400-485 is the wireless bridge used for the AD400 series of locks. It should be programmed before you add any Schlage doors in Verkada Command.

The SUS connects to the PIM 400-485, using the SUS cable.

  1. Connect the Schlage SUS cable to the phone using USB C.

  2. Connect the PIM 400-485 to the power supply and connect the SUS-A cable to the phone and the PIM.

  3. Launch the Schlage Utility Software - SUS app.

  4. If this is the first time you log in to the SUS app, you need to set the password:

    • User type: Manager

    • Password: 123456

  5. Reset the password as verkada.

  6. The SUS app prompts you to log in, where you use:

    • User type: Manager

    • Password: verkada

    If you log in to the SUS app and the SUS-A cable is not connected, the “CABLE NOT CONNECTED” message displays.

  7. When you connect the SUS-A cable, the Android operating system prompts: “Allow Schlage Utility Software to access SUS A-CABLE?”. Click OK.

  8. When you connect the PIM to the phone, you need to couple it. (This means that the PIM is programmed to communicate with the specific programming phone.) You can only couple a PIM to one phone. If you try to do anything when the PIM isn't coupled, you get an authentication error (E303).

    1. Couple the PIM by placing it into coupling mode: Press and hold LINK1 and then press LINK2 (do this 3 times).

    2. Click Couple [PHONE_NAME] to Device, where [PHONE_NAME] is a placeholder. Yours will be different.

Note: If the PIM is already coupled to a device, these steps won’t work and you'll have to do a factory reset. If the coupling is successful, you should see a message.

Once you've coupled the PIM to the SUS phone, you can start programming it.

Program the PIM 400-485 to the SUS phone

  1. Tap Device Configuration to begin defining the PIM addresses.

  2. Required. Define these fields:

    • RS485 Address—Address of the PIM in relation to the AC41/AC42.

    • Low Door—First door address that belongs to the PIM.

    • High Door—Address of the last door that the PIM controls. It should be 4 more than the Low Door number. For example, if your Low Door is 1, your High Door can be anything between 2 (implying you intend to only connect 2 doors) and 16 (implying you intend to connect the maximum 16 doors to the 1 PIM).

Example: Setting the PIMs address to 254 and its door address span from 251–254

Configure the AC41/AC42 lock

Note: To avoid complications all devices, AD300s, AD400s, PIM 400-485 should have their own unique address. Though, a PIM 400-485's RS-485 address can be the number as one of its doors as shown above.

Verkada's AC41/AC42 supports any combination of wireless locks (via the PIM 400-485) hub and wired AD300 locks, up to 16 per AC41/AC42.

  1. When connecting multiple RS485 devices, connect each of the data pins (A and B) in parallel to each other and to the AC41/AC42's AUX RS-485 bus.

    1. Each RS-485 slot on the AC41/AC42 can only supply enough power for one device.

    2. If you're wiring in multiple devices (AD 300s and PIM 400-485s), you can use the reader power from the 4 door cassettes above.

    3. All Schlage devices beyond 5 (4 door cassettes + 1 AUX cassette) must receive power from an external power supply.

  2. If using multiple Schlage devices, such as a PIM hub and an AD300, wire the data pins in parallel to each other. They are addressed so the AC41/AC42 knows which one it's talking to.

Note: The Verkada integration limits each PIM to 16 wireless locks.

Set up the AD400 lock with AC41/AC42

Mount the hardware

In most cases, a locksmith or contractor will be following these instructions.

To begin, the AD400 requires more holes to be bored into the door for it to function because of the built-in DPI sensor. For hardware installation instructions, read Schlage AD Series Cylindrical Installation Instructions.

  • The cables are fragile and should be handled carefully.

  • If the lid isn't screwed on tight enough, the tamper switch will repeatedly and randomly throw errors.

  • You will need to get your own wire to connect the AD400 lock to the PIM. A standard-shielded, low voltage cable is fine (22/4, 22/6, or 18/4 should all work flawlessly).

Configure the AD400 lock

You must give all AD400 locks an address: Use the SUS, which is a free Android app (there is no iOS app).

To configure the AD400 lock, you link it to the PIM.

  1. Couple the PIM to the phone to enable it to program itself.

  2. The SUS connects to the lock using the SUS cable.

  3. Connect the Schlage SUS cable to the phone using USB C.

    The SUS cable connects the AD lock via a USB A host connection. The AD has a hidden USB port under a rubber cover on the bottom of the unsecured side of the door, a connected SUS cable.

  4. Now that the cable is connected, you can put the AD lock into communication mode: Press and hold the # key (on ADs that have a keypad) or Schlage (on readers that don't have a keypad).

  5. Couple the device: Click Couple [PHONE_NAME] to Device. This fails if the device is not in coupling mode.

    Note: If a device is already coupled to a different SUS phone, you need to reset it completely to couple it.

  6. Pair the AD400 to the PIM device. With the SUS cable plugged into the PIM (not the AD400), click Device Configuration, then the link. The PIM400 stays in link mode for up to 30 minutes.

  7. Select the door address you want to link an AD400.

  8. Put the AD400 lock into link mode: Press and hold the # key (on ADs that have a keypad). On readers that don't have a keypad, depress and hold down the latch (or crash bar) and present a credential to the reader; for example, a card or key fob.

  9. Once the lock begins to flash red and green, you can release the latch/crash bar. If the lock successfully pairs to the PIM it will flash green and beep, indicating that it was successful.

  10. When the linking is complete, the PIM400 automatically exits link mode.

Connect the PIM/AD300 to the AC41

The PIM (or AD300 lock) connects to the AC41 over a single pair RS-485. This means that you need to use 2 wires for data and 2 wires for power. You can take power from 1 of the 12v outputs in the AC41. The AC42 uses door port 1 instead of AUX.

  • The port on the PIM labeled TDA- goes into the A port of the AUX cassette of the AC41.

  • The port on the PIM labeled RDB+ goes into the B port of the AUX cassette of the AC41.

Connect the PIM/AD300 to the AC42

The PIM (or AD300 lock) connects to the AC42 over a single pair RS-485 on door port 1. This means that you need to use 2 wires for data and 2 wires for power. You can take power from 1 of the 12v outputs in the AC42.

  • The port on the PIM labeled "TDA–" goes into the A port of the AUX cassette of the AC42.

The port on the PIM labeled RDB+ goes into the B port of the AUX cassette of the AC42.

Set up the Command installation

Add the AC41/AC42 to Command

To add the AC41/AC42 to Command, the AC41/AC42 needs to be set to Schlage Mode. You can only configure this setting when you add the controller to Command. If you forget, you need to decommission the AC41/AC42 and then re-add it.

You can verify that your device is in Schlage Mode on the Devices list page. Only Schlage locks can be connected to a Schlage Mode AC41/42.

Add an AD400 door

  1. In Command, go to All Products > Access Home > Controllers.

  2. Select a location and at the top, click Add.

  3. Select Wireless-AD-400 and fill in the PIM 400-485 addresses and corresponding AD400 addresses. You should be able to see the paired PIM and door addresses in the SUS app. Once this information is entered, it is associated with the door.

  4. AD400s have door position indicator (DPI) and request to exit (REX) built into the device. In the door installer Settings page, you can see that both DPI and REX are on, by default. If your DPI requires additional door hardware that is not installed, disable DPI.

    You should see that your newly added AD400 door. (Be patient—it can take a few minutes for the door to display.)

Add an AD300 lock type

  1. In Command, go to All Products > Access > Controllers.

  2. Select a location and at the top, click Add.

  3. Select Wired-AD-300 and configure the Hub Address.


  • You do not use the PIM with the AD300; it wires directly to the AC41/AC42 AUX cassette.

    • We can support multiple AD300s connected to one AC41/AC42 by wiring them in parallel.

    • At maximum, 1 AC41/AC42 can support 16 doors total.

  • You only configure the door address for AD300s since there is no PIM to configure an address for.

Troubleshooting guidelines

  • Verify that your access controller unit (ACU) is in Schlage Mode. If you forgot to set it to Schlage Mode, you need to decommission it and re-add it.

  • Verify that the AD400s and PIM 400-485s have been successfully paired.

  • Ensure that the addresses for each PIM400-485 and AD400 were successfully configured.

  • Verify that the addresses provided (when setting up the door in Command) are correct.
