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.

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.

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

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:

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:

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.

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.

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.

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.
