“Engaging”, “opening”, “locking”, etc.

Different locking device types respond differently to an authorised identification medium due to their design:

Locking device	Response	User action
Locking cylinders	Engage: The electronic thumb-turn connects to the cam mechanically.	Open: Turn thumb-turn. Take the door handle. Pull open door with door handle.
SmartHandles	Engage: The handle on the electronic side connects to the spindle mechanically.	Open: Press the handle. Pull open door with door handle.
SmartRelays	Switching: The relay contact in SmartRelay switches. Depending on the SmartRelay, this is a make contact or a changeover contact. Connected electrical doors now open.	No further action required. The door is generally already open.
SmartLocker AX	Retract dead bolt: The motor block in the SmartLocker retracts the dead bolt and releases the door.	Open: Pull the door open.
