Allegion US, a pioneering provider of security solutions, technology and services, has introduced the latest addition to the Schlage® L Series: Motorized Latch Retraction mortise locks, a multi-category winner in the Campus Security Today Secure Campus Awards.
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. 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.
Introduction of motorized latch retraction
"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," said Jim Bembenek, senior project manager at Allegion US.
"This innovation reflects our commitment to creating smarter, more efficient access solutions that meet the evolving needs of our customers."
Quiet control
Three functions offer latch retraction for momentary or continuous operation
Quiet control is the hallmark of these L Series locks. Unlike competitors, the 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.
patent-pending feature
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.
Variety of applications
As part of the L Series mortise family, motorized latch retraction functions fit a variety of applications
As 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.
Longevity of Schlage’s electrified mortise line
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. And, as part of the L Series family it offers the same strength, dependability and longevity of Schlage’s most popular electrified mortise line.
