The Schlage® NDE mobile enabled wireless cylindrical lock is designed to affordably extend electronic access control deeper into the building beyond traditional perimeter and high security openings. It can function in offline or No-Tour mode or as a networked lock with either periodic check-ins or real-time management.

The open architecture design allows the NDE to be managed by Allegion software or to be integrated into popular physical access control systems through our PACS Alliance program. This enables customers to choose the system that best fits their requirements and gives them the ability to move to a fully networked solution at any time.

The NDE is compatible with a wide range of mobile, smart and proximity credential technologies and can operate in storeroom, office, privacy, or apartment functions using its interior push button with indication.

NDE works within existing network architecture and can exist in the same EAC system as other wireless locks including Schlage Control™, AD-400 and LE.

Schlage NDE and LE Locks with SI option were named winner in the Locks and Door Hardware category for the first-ever Security Info Watch Reader's Choice Awards.
