Accentra 5490LN Fail Safe Electrified Lever

The Accentra 5490LN Fail Safe Electrified Lever offers dependable, power-controlled security for busy commercial and institutional doors. It uses a deadlocking latchbolt that works from both sides, and when power is on, the outside lever stays locked for controlled entry. When power goes off, the outside lever unlocks at once, which helps ensure safe access during outages. At the same time, the inside lever remains free so people can always exit quickly. Because of its strong build and simple wiring, this lever works well in places that need reliable and safe access control.

Available Options

• Cylinder Override (Complete Lockset): Includes a mechanical key cylinder for backup manual access in addition to electronic operation.
