LF Series cylindrical locks are also available for electrified options for access control systems in high-security applications.


RX – Request to Exit

The RX feature is used to signal the use of an opening. Equipped with one internal SPDT switch which monitors the turning of the lever. The device can be connected to a security console or may be used as a single door alarm when used with a horn and power supply.

EL – Electrically Locked (Fail Safe)

Fail Safe locks require power to lock. In the event of a power outage the door will automatically unlock, thus ensuring a safe egress during emergency situations.

EU – Electrically Unlocked (Fail Secure)

Fail Secure locks require power to unlock. In the event of a power outage the door will automatically lock, thus preventing access and protecting all assets within it.

The use of this feature is not permitted on fire doors.
