Electrified Mortise Locks Explained: Types, Functions, and Applications

Electrified mortise locks are a cornerstone of modern commercial access control. They combine the strength and durability of a traditional mortise lock with electronic control for credential-based access, door automation, and centralized security management.

Unlike cylindrical locks, mortise locks are installed into a pocket within the door, offering superior strength, cleaner trim alignment, and long-term reliability—especially in high-traffic environments like schools, offices, healthcare facilities, and government buildings.

This guide breaks down the most common electrified mortise lock functions, with a spotlight on Command Access solutions and a quick overview of other major manufacturers.

Command Access Electrified Mortise Lock Functions

Command Access offers a wide range of electrified mortise lock bodies designed to retrofit standard mortise preps while integrating with access control systems. Their ML-Series is popular for flexibility, reliability, and compatibility with existing door hardware.

• Inside lever is always free for immediate egress
• Available in EU (electronically unlocked) function only

Best for: Single-user rooms, private offices, controlled privacy spaces

Spotlight: Command Access LPM190 Motorized Mortise Lock

The Command Access LPM190 Series is a motorized latch retraction mortise lock built on a high-quality Grade 1 chassis. It brings latch retraction to a standard mortise lockset and is a strong option for openings where panic hardware is unnecessary.

Ideal applications include:

• Push/pull doors
• ADA & handicap-accessible openings
• Single-occupancy restrooms
• Automatic door operators
• Interior doors requiring hands-free access

Key highlights:

• Standard Type 86 mortise prep
• Direct retrofit to Schlage L9000 compatible trim
• Available as chassis-only or with complete trim
• Optional lever control solenoid for specialty functions
• Motor design helps maximize pulling force while lowering surge for longer wire runs and multi-lock power supplies

Electrical overview (high level):

• Latch retraction voltage range: 24VDC ±10%
• System protection: shutdown when voltage exceeds 28VDC
• Average peak current: ~1A
• Average hold current: ~300mA
• Operating voltage options: specify 12V or 24VAC/DC (±10%)
• Amperage: 24V = 350mA or 12V = 700mA

Other Popular Electrified Mortise Lock Brands

While Command Access excels at retrofit electrification, several major manufacturers offer factory-electrified mortise solutions. Lead times, prep requirements, trim compatibility, and serviceability vary, so selection often depends on whether the project is new construction or a retrofit.

• Schlage – L9000 series with electrified options, widely specified and code-friendly
• SARGENT – Institutional mortise platforms with advanced access control integrations
• Corbin Russwin – Durable solutions commonly used in healthcare and education
• Yale – Broad mortise offerings with electrified trims and smart access integrations

Final Thoughts

Electrified mortise locks provide a strong balance of security, durability, and access control flexibility. Whether you need classroom lockdown, storeroom control, deadbolt security, or motorized latch retraction, choosing the correct function is key for code compliance and long-term performance.

Understanding the differences between functions—and knowing when to use solutions like the Command Access ML-Series or LPM190 motorized mortise lock—can save time, reduce installation issues, and future-proof your openings.
