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. In this example, we will show how by using the wireless lock Schlage AD400 paired with a PIM400-485.

Hardware List

  • AC41

  • 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 will vary depending on the installation. Please reach out to your Allegion ESE for assistance.

Installation Order of Operation

  1. Install and configure the PIM 400-485

  2. Install and configure the lock

  3. Configure the AC41

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 Command.

Installation

  1. The Schlage Utility Software connects to the PIM 400-485. using the SUS cable. 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 app.

  4. The Schlage Utility Software app will ask you to log in. Use:

    1. User type: manager

    2. Password: verkada

    If you log in to the SUS app and the SUS-A cable is not connected, you will get a screen that says “Cable not connected”.

  5. Upon connecting the SUS-A cable the Android operating system will ask if you “Allow Schlage Utility Software to access SUS A-CABLE?”. Select “OK”.

  6. When you connect the PIM to the phone you will 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'll get an authentication error.

You can couple the PIM by placing it into coupling mode by pressing and holding the LINK1 button and then pressing the LINK2 button three times. Next, click “Couple [PHONE_NAME] to Device”

Note: [PHONE_NAME] in the above example is a placeholder. Yours will be different.

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 will see a message at the bottom. Now that you've coupled the PIM to the SUS phone, you can start programming it.

PIM 400-485 Programming

Tap into Device Configuration to begin defining the PIM addresses. Three fields need to be defined; they are:

  • RS485 Address - This is the address of the PIM in relation to the AC41.

  • Low Door - this is the first door address belonging to the PIM.

  • High Door - This is the address of the last door to be controlled by the PIM. It should be four more than the Low Door number. For example, if your Low Door is 251, your High Door Must be 254.

Verkada's AC41 supports any combination of wireless locks (via the PIM 400-485) hub and wired AD300 locks, up to four per AC41. When connecting multiple RS485 devices, connect each of the data pins (A and B) in parallel to each other and to the AC41's AUX RS485 bus.

Note: Please note that the Verkada integration limits each PIM to 4 wireless locks.

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 knows which one it's talking to.

AD400

Setting up the AD400 with the AC41 requires several steps:

  1. Mount the hardware and configure the lock

  2. Configure the PIM module (you should have done this before installing the AD400)

  3. Setup in Command

Installation

Most of the time the locksmith or contractor will be doing this part following the included instructions. 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, please see: Schlage AD Series Cylindrical Installation Instructions

Note:

  • 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 to the PIM. Standard shielded low voltage cable will be fine. 22/4, 22/6, or 18/4 should all work flawlessly.

AD400 Lock Programming

All AD400 locks need to be given an address. This is done using the Schlage Utility Software (SUS,) which is a free Android app (there is no iOS app).

To configure the AD400, you first start by linking it to the PIM. The first step is to couple the PIM to the phone to enable it to program itself.

  1. The Schlage Utility Software connects to the lock using the SUS cable. Connect the Schlage SUS cable to the phone using USB C.

  2. 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.

  3. A connected SUS cable.

Now that the cable is connected you can put the AD lock into communication mode by pressing and holding the # key on ADs that have a keypad or the Schlage button on readers that don't have a keypad.

Couple the device by selecting Couple [PHONE_NAME] to Device. This will fail if the device is not in coupling mode.

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

The next step is to pair the AD400 to the PIM device. With the SUS cable plugged into the PIM, NOT the AD400, select device configuration, then link.

Now that the cable is connected to the PIM, you can put the AD lock into link mode by pressing and holding the # key on ADs that have a keypad or the Schlage button on readers that don't have a keypad. The PIM400 will stay in link mode for up to 30 minutes. When the linking is complete, the PIM400 will automatically exit link mode.

Connecting the PIM/AD300 to the AC41

The PIM (or AD300 lock) connects to the AC41 over a single pair RS485. This means that you need to use two wires for data and two wires for power. You can take power from one of the 12v outputs in the AC41.

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.

Command Installation

Adding the AC41 to Command

When adding the AC41 to Command, the AC41 will need to be set to “Schlage Mode”. This setting can only be set when adding the controller to Command. If you forget, you will need to decommission the AC41 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.

Adding an AD400 Door

  1. Navigate to the “Add Door” page in Command.

  2. Select the type of door you would like to add. Then, fill in the PIM 400-485 addresses and corresponding AD400 addresses. You will be able to see the paired PIM and door addresses in the Schlage sus app. Once this information is entered it will be associated with the door.

  3. AD400s have DPI and Rex built into the device. In the door installer settings page, you will see that both DPI and Rex are on by default. If your DPI requires additional door hardware that is not installed please disable DPI.

  4. You will now see that you have added an AD400 door. It can take a couple of minutes for the door to come online.

Adding an AD300 Door

  • You do not use the PIM with the AD300 - it wires directly to the AC41 aux cassette.

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

    • At max, 1 AC41 can support 4 doors total.

  • You have to select Wired - AD300 when adding AD300 locks to Command.

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

Troubleshooting Guidelines

  1. Verify that your ACU is in Schlage mode - if you forgot to set it to Schlage mode, you will need to decommission it and re-add it.

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

  3. Ensure that the addresses for each PIM400-485 and AD400 were successfully configured. Additionally, ensure that the addresses provided when setting up the door in Command are correct.
