AD Series Wireless Lock Setup

Learn how to use wireless locks with your Verkada access controller

Updated over 4 months 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/AC12. This article focuses on how to use the wireless lock Schlage AD400 paired with a PIM 400-485.

Before you begin

You will need the following hardware:

  • AC41/AC42/AC12 -Referred to as ACU.

  • NOTE: The AC62 does not support Wireless locks.

  • Schlage Utility Software (SUS) only compatible with android devices

  • SUS cable

  • PIM 400-485 (PIM)

  • AD400 lock

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

What you need to know

  • While in Schlage mode, the ACU cannot control traditional wired doors/Verkada Readers.

  • The ACU can control up to 16 wireless locks. If you do not see ability to add more than 4 doors please contact support.

Install and configure the PIM

The PIM 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 software connects to the PIM's USB, using the SUS cable.

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

  2. Wire the PIM 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.

  6. Login to Sus app:
    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 one PIM to one phone at a time.

    1. Couple the PIM by placing it into coupling mode: Press and hold LINK1 and then press LINK2 (do this 3 times). If you try to do anything when the PIM isn't coupled, you get an authentication error (E303).

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

If the PIM is already coupled to a device, these steps will not work and you will need to conduct a factory reset of the PIM. If the coupling is successful, you should see a message.

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

Program the PIM with the SUS application

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

  2. Required. Define these fields:

    • RS485 Address—Address of the PIM in relation to the ACU.

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

    • High Door—Address of the last door that the PIM controls.

The Low Door and High Door addresses need to be 4 units apart. Example: Set the RS485 Address at 0. The Low Door address as 0 and the High Door as 3. This is important for when there are multiple hubs/locks in setup. Lock addressing can never overlap, so on next hub (1) locks need to start at 4 for low and 7 for high.

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

Program and Wire the Door

Verkada's ACU supports the combination of wireless locks via the PIM400-485 Hub and wired AD300 locks. The ACU supports up to 4 wired connections per panel and up to 16 locks per ACU for example, up to 3 PIM hubs and 1 AD300 lock.

Set up the AD400 lock with Verkada ACU

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, you may see degraded lock performance if any cables are pinched. If the lid is not screwed on properly this could result in the tamper switch being triggered and cause the lock to output errors.

Configure the AD400 lock

You must give all AD400 locks an address.

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

  1. Couple the PIM to the phone.

  2. The SUS application 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.

  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 button (on readers that do not 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 will need to factory reset it twice in order to couple it for this installation.

  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 option. The PIM stays in link mode for up to 30 minutes.

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

  8. Put the AD400 lock into link mode: Depress and hold the inside lever or exit device push bar and either present a credential to the reader (ex: card or key fob) or press the # key on the keypad (if using lock with keypad).

  9. Once the lock begins to flash red and green, you can release the lever/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.

Wiring the PIM to the AC41

The PIM 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.

  • For AC41 integrations, wire the PIM to the RS-485 inputs on the AUX cassette.

+ > 12 VDC +

- > 12 VDC -
A > TDA -
B > RDB +

Wiring the PIM to the AC12/AC42

The PIM connects to the AC12/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.

  • For AC42 integrations, wire the PIM to the RS-485 inputs on Door 1.

  • For AC12 integrations, wire the PIM to the RS-485 inputs on Reader 1.

+ > 12 VDC +

- > 12 VDC -
A > TDA -
B > RDB +

For wiring more than 1 PIM Hub to ACU

ACU cannot support daisy chaining power for multiple PIM hubs, but does require data to be in parallel or daisy chained.

  • Can wire up to 4 PIM Hubs per ACU

  • Each Hub must be powered individually

    • For AC41/42, can draw power from other door ports or an external power supply for each additional PIM

    • For AC12, external power supplies are required for each additional PIM

  • Data Wires (A&B) must all be wired in parallel or daisy chained to AUX/Door 1 RS-485 inputs.

Add access control unit and locks to Command

  1. In Verkada Command, go to All Products > Devices.

  2. Click Add Device.

  3. Type your ACU serial number and click Add 1 Device.

  4. From the unassigned devices list, click the new access controller and click Set Up.

  5. On Setup:

    1. Ensure that the ACU is in Schlage device mode.

    2. Ensure that a site, building, and floor are assigned.

Add an AD400 door

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

  2. Select the ACU wired to the PIM > in the top right select the + Add to add a new door.

  3. Select Add Door from pop-up, Wireless-AD-400 and fill in the PIM 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 your newly added AD400 door listed in Command under the Access Controller page. This can take some time to sync. After 5-10 minutes if a Command page refresh does not show the lock as connected, test a keycard or keycode entry to generate connectivity.

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.

  • Test door in demo mode using SUS application to ensure connectivity between PIM and Door.

  • Ensure that the addresses for each PIM and AD400 were successfully configured and are matching Command configurations.
