A device can only support one DESFire type at a time. Switching a device back to its default configuration to restore Schlage DESFire compatibility is a paid service. —

! Once a tenant is linked with Engage, credential enrollment changes — presentation enrollment must happen at a Schlage Reader Controller, and existing credentials must be migrated or re-enrolled before they work at Schlage devices

• An RC04 pigtail-to-SRC adapter cable is available: P/N 47609539 – RC04 to SRC Adapter Cable.
• Active Directory integration is available only for RMR and 51+ door licenses.
  

*Confirm the credential format and enrollment method match the target device type before deploying a mixed ISONAS and Schlage environment.

Setting	Behavior with Schlage devices
Credential Time Limit	Resolves to the hour, not the minute. A 9:40–11:15 window approves the credential between 9:00 and 11:00.
Credential Count Limit	Approvals at Wi-Fi devices do not deduct from the count limit on check ins.
Global Re-lock Time	Does not currently apply to Schlage devices.
AUX outputs / RS-485	Schlage RC adds a separate AUX input, two AUX outputs, and an RS-485 connection, but Pure Access Cloud does not currently support the AUX outputs or RS-485 connection. Editor note: verify this is still accurate before publishing.
