Schlage L9492EU — Electrically Locking/Unlocking Outside Levers, Outside Cylinder Override with Deadbolt
The L9492EU function keeps the outside lever continuously locked (EL) or unlocked (EU) via 12V or 24V DC, while the deadbolt is independently actuated by key outside or thumbturn inside. The inside lever always retracts both the deadbolt and latchbolt for immediate egress — making this the right choice for controlled-access commercial openings that require both electric lever control and a keyed deadbolt override.
- Outside lever continuously locked (EL) or unlocked (EU) by 12V or 24V DC
- Deadbolt thrown or retracted by key outside or thumbturn inside
- Inside lever retracts both deadbolt and latchbolt for immediate egress
- EU mode: outside lever also retracts deadbolt and latchbolt
- Auxiliary latch deadlocks latchbolt when door is closed
- Inside lever always free — no trapped egress
