The Schlage 194555261945 is the OEM motorized latch retraction (MLR) chassis for the L9692EU and L9696EU functions in the Schlage L Series mortise lock family. It is the mortise lock body with both motorized latch retraction and lever control built into a single chassis, configured for EU (Electrically Unlocked, Fail Secure) operation. The cylinder is not included. This chassis ships fewer cylinders and requires a field-installed cylinder at time of installation.

This is not a standard electrified L Series chassis. It is specifically the MLR-with-lever-control variant, combining two distinct electrified functions in one lock body, something that previously required separate electric strike hardware and lever control locks to achieve. Confirm the installed or specified function (L9692EU or L9696EU) before ordering, as the lever locking behavior differs significantly between the two.

Schlage Retraction Chassis: MLR With Lever Control vs Latch Retraction Only

The L Series MLR family breaks into two groups per the Allegion installation document (48124648). The first group, L9510/L9580/L9582, offers latch retraction only when the motor retracts the latch bolt on an electrical signal, but the lever mechanism is not electrically controlled. The second group, L9692EL/EU, L9695EL/EU, and L9696EL/EU, offers motorized latch retraction plus separate lever control. The 194555261945 chassis covers L9692EU and L9696EU, the two fail secure functions in this second group.

The motor in this chassis is a 24VDC stepper motor that produces high torque at low speeds. It operates quietly, which makes it particularly well-suited for healthcare environments, clean rooms, and any high-traffic access point where solenoid-click noise from repeated access events becomes a problem. Allegion's patent-pending binding detection feature is built into the motor control  it monitors for side load, warped door pressure, and static binding conditions and adjusts motor output automatically to overcome them rather than stalling.

L9692EU vs L9696EU: Critical Function Difference

Both functions in this chassis are EU (Fail Secure). When power is applied, the outside lever unlocks and the latch retracts. When power is removed or fails, the outside lever returns to the locked state. This is the correct mode for any door that must remain secured during a power outage.

The distinction between L9692EU and L9696EU is in which levers are controlled. The L9692EU controls the outside lever; only  the inside lever always remains free for egress at all times, which makes it compatible with standard commercial occupancy doors. The L9696EU controls both the inside and outside levers. Per Allegion's installation warning: locking both levers prevents normal egress from inside and prevents the intended operation of emergency exit hardware. The L9696EU is reserved for specific high-security applications  pharmaceutical vaults, secure data rooms, psychiatric units  where bi-directional lever control is a code-permitted requirement and the installation includes compliant panic hardware on the same opening.

Note: RX (Request-to-Exit) monitoring is available on L9692EU but NOT on L9696EU. LX (latchbolt monitoring) is available on both.

Schlage L Series Hardware: MLR Chassis as Electric Strike Replacement

The MLR chassis was introduced as a direct replacement for electric strike installations. Electric strikes leave the latch mechanism exposed at the frame, creating a vulnerability to manipulation if not protected with a latch guard. The Schlage MLR chassis retracts the latch bolt within the door-mounted lock body itself, removing the exposed frame-side mechanism entirely. The result is a more secure, cleaner installation that fits the same L Series mortise pocket no door or frame modification required when retrofitting from a standard L Series lock.
