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 AC41/42. In this example, we will show how by using the wireless lock Schlage AD400 paired with a PIM400-485.
Note: AD Series Wireless Locks and the Verkada AD31 and AD32 readers can not be used in the same installation.

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.
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.
Connect the PIM 400-485 to the power supply and connect the SUS-A cable to the phone and the PIM.
Launch the Schlage Utility Software app.
If this is the first time you login to the Schlage Utility Software app, you will need to set the password. Enter the following:
a. User type: Manager
b. Password: 123456
Next, set the password as: verkada
The Schlage Utility Software app will ask you to log in. Use:
User type: Manager
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”.
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”.
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 AC41/42.
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 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).
Here is an example of setting the PIMs address to 254 and its door address span from 251-254.
ADDRESSING Best Practice: To avoid complications all devices, AD300s, AD400s, PIM 400-485 should have their own unique address. Even though technically a PIM 400-485s RS485 Address can be the number as one of its doors as we see in the photo above.
Verkada's AC41/42 supports any combination of wireless locks (via the PIM 400-485) hub and wired AD300 locks, up to 16 per AC41/42. When connecting multiple RS485 devices, connect each of the data pins (A and B) in parallel to each other and to the AC41/42's AUX RS485 bus. However, each RS485 slot on the AC41/42 can only supply enough power for one device. So, if you are wiring in multiple devices (AD 300s and PIM 400-485s) you can use the reader power from the 4 door cassettes above. All Schlage devices beyond 5 (4 door cassettes + 1 AUX cassette) must receive power from an external power supply.
Note: Please note that the Verkada integration limits each PIM to 16 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 AC41/42 knows which one it's talking to.
Setting up the AD400 with the AC41/42 requires several steps:
Mount the hardware and configure the lock
Configure the PIM module (you should have done this before installing the AD400)
Setup in Command
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
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.
The Schlage Utility Software connects to the lock using the SUS cable. 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.
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.
The PIM400 will stay in link mode for up to 30 minutes.
Now you can put the AD400 lock into link mode by pressing and holding the # key on ADs that have a keypad. On readers that don't have a keypad, depress and hold down on the latch (or crash bar) and present a credential to the reader, for example a card or key fob.
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.
When the linking is complete, the PIM400 will automatically exit link mode.
Connecting the PIM/AD300 to the AC41/42
The PIM (or AD300 lock) connects to the AC41/42 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 AC41/42.
The port on the PIM labeled TDA- goes into the A port of the Aux cassette of the AC41/42. The port on the PIM labeled RDB+ goes into the B port of the Aux cassette of the AC41/42.
AC41/42 AUX Cassette
Adding the AC41/42 to Command
When adding the AC41/42 to Command, the AC41/42 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 AC41/42 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.
Adding an AD400 Door
Navigate to the “Add Door” page in Command.
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.
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.
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 AC41/42 aux cassette.
We can support multiple AD300s connected to one AC41/42 by wiring them in parallel.
At max, 1 AC41/42 can support 16 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.
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.
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. Additionally, ensure that the addresses provided when setting up the door in Command are correct.
