AD-300 Lock Setup Guide

AD-300 Lock Setup Guide

1.0 Introduction

Allegion Schlage AD-300 networked, hardwired locks can be integrated seamlessly with the Doors.NET software when used with the NXT-MSC (Mercury-Powered controllers). You can connect and communicate with up to 32 AD-300s via the controller's RS-485 communication buses.

The AD-series locks have extensive functionality and operating modes and are combined units consisting of the electric lock, credential reader, request-to-exit and request-to-enter sensors, door position switch and tamper guard.


For standard applications the AD-300 can be customized with a variety of credential readers including keypad, magnetic stripe or multi-technology which can read both proximity and smart-card technology.


Note: Effective from Doors.NET v5.2.0, when using NXT-MSC controllers you will need to delete the Keri NXT reader which is added to the bus by default and then configure the protocol to support the Schlage RSI protocol before adding the PIM-400.


AD300 Schematic



Note: Effective from Doors.NET v5.2.0 you can mix and match ENGAGE Gateways, PIM-400s and AD-300s on the same bus. You can add up to 8 x ENGAGE Gateways, 8 x PIM-400s or 32 AD-300s (to each controller bus). Adding one of these supported devices will reduce the number of other devices that can be added to the bus. For example, if 4 x ENGAGE gateways are added you will then be limited to adding 4 x PIM-400s or 28 AD-300s.

Maximum Number of Locks Per Bus and Per Controller

  1. The maximum number of AD-300 locks per bus is 32 (if you only have AD-300s on the bus).
  2. The maximum number of AD-300 locks you can add to an NXT-MSC 2D or 4D controller is 64.

4.0 Configure the AD-300 With the Schlage™ Utility Software and Android App

The Schlage Utility Software (SUS) is an application that runs on supported Android devices. It is used to configure, edit and program all supported devices.

You can use the app to; edit the AD-300 lock properties, update the lockset's firmware, couple the HHD to the device, set the date/time and run diagnostics.

This section assumes that you have already:


  • Downloaded and installed the SUS Android app.

4.1 Logging into the App for the First Time

  1. Once the application is downloaded, you must change default password.
  2. Select User Type: Manager or Operator.
  3. Enter Default Password: 123456.
  4. You will be prompted to enter a new password and confirm the new password.

    >> New password must not be a default password, subset or super set of default password.

  5. You must log in again with User Type: Manager or Operator and new password.

4.2 Connecting the Mobile to the AD-300

This section explains how to connect the mobile device to the AD300 locks:


Note: The mobile device must have file transfer via USB enabled to function properly.

  1. Start the Schlage Utility Software for Android (SUS-A).
  2. Connect the SUS-A Cable to the mobile device. A pop-up will appear, “Allow Schlage Utility Software to access SUS A-CABLE?” Click OK to continue.

    SUS USB Connection

  4. Press the Schlage button twice to begin communication.
  5. The lock will be displayed on the screen.


4.3 Couple the Mobile Device to the AD-300 Lock

AD-Series locks can be coupled, or authenticated, with the mobile device. This provides enhanced security by ensuring that the lock will only communicate with mobile device(s) to which it has been coupled. Once the lock has been coupled, the Coupling Password is passed to the device from the mobile device during programming.



  • Mobile devices with the same coupling password can program the same devices. Once the mobile device and lock are coupled, the coupling password is disabled in the lock and any mobile device with the correct coupling password will automatically couple with the lock.
  • The mobile device will use a default Coupling Password (123456) when coupling with a device. The Coupling Password should be changed to provide increased security for your locks.
  • If a device is not in Coupling mode, SUS-A will display a device specific message with instructions for placing the device into Coupling mode.


4.4 Steps to Couple with the AD-300 Lock

  1. Connect the mobile device to the lock using the SUS-A cable.
  2. Press the Schlage button twice. The lock will be displayed on the screen.
