Allegion US has introduced the Motorized Latch Retraction mortise locks to the Schlage L Series.
First released to the market in March 2025, latch retraction capable L Series Grade 1 locks create application opportunities across many markets, whether the need is security, controlled access or hands-free operation.
The company says that they can replace the need for electric strike use in a form that is more secure and aesthetically pleasing.
Quiet operation makes them ideal for healthcare environments or anywhere disturbances from repeated user exit and entry occurs.
Jim Bembenek, Senior Project Manager, Allegion US commented: “With the introduction of motorized latch retraction to our trusted L Series, we’re providing a solution that not only enhances security and improves accessibility, it also delivers quiet, seamless operation for demanding environments like healthcare and education.
“This innovation reflects our commitment to creating smarter, more efficient access solutions that meet the evolving needs of our customers,” Bembenek concluded.
Quiet control is the hallmark of these L Series locks.
Unlike competitors, the company says that its Motorized Latch Retraction locks are offered in six functions that span keyed, non-keyed and lever control options.
All employ an ultra-quiet stepper motor using 24V DC to produce high torque at low speeds. Three functions offer latch retraction for momentary or continuous operation.
Allegion says that the three additional functions also feature lever control allowing the locking and unlocking of the lever managed by a separate motor.
Nearly all allow options for both request-to-exit (RX) and latchbolt (LX) monitoring.
Additionally, a patent-pending feature detects binding conditions on the motor and adjusts as needed to overcome side load, static pressure and warped door conditions.
The company notes part of the L Series mortise family, motorized latch retraction functions fit a variety of applications.
It can be retrofitted to the same pocket of a standard L Series mortise and electrified through the door allowing the frame to stay intact.
Wiring then connects on the same side as an auto operator for situations requiring hands-free operation such as accessible restrooms, Allegion adds.
Other hands-free uses include infection control and clean room applications, spaces requiring cart access, delivery doors and high security data centers where robotic access may be needed.
Other applications include openings requiring limited or timed access and in K-12 schools where controlled access for visitor entrances, administration offices, or classroom doors is needed.
Allegion reports that as part of the L Series family it offers the same strength, dependability and longevity of Schlage’s most popular electrified mortise line.
