If you're specifying or installing Schlage LE wireless mortise locks, you'll encounter model suffixes like LEMS, LEMD, LEBMS, and LEBMD. These suffixes define how the lock mechanically functions—especially in terms of deadbolt behavior and interior egress.
Here’s what each part of the model code means and when to use it.
The Core Breakdown
| Model | Deadbolt | Interior Lever Action | Use Case |
|---|---|---|---|
| LEMS | No deadbolt | Always retracts latch | Standard mortise access (e.g., office, classroom) |
| LEMD | Manual deadbolt | Lever does not retract deadbolt | Private offices, spaces needing manual locking |
| LEBMS | Auto deadbolt | Lever retracts deadbolt | High-security with single-motion egress (e.g., apartment entry) |
| LEBMD | Auto deadbolt | Lever does not retract deadbolt | Secure rooms requiring intentional dual-motion egress |
LEMS – Mortise Lock, No Deadbolt
- Function: Standard mortise lock with latch only, no deadbolt
- Interior Lever: Always retracts the latch for exit
- Best For: Offices, classrooms, utility closets where no deadbolt is needed
Think of it as your basic mortise access control—secure but straightforward.
LEMD – Mortise Lock with Manual Deadbolt
- Function: Includes a manually thrown deadbolt
- Interior Lever: Does not retract the deadbolt—user must unlock it separately
- Best For: Private offices, executive spaces, or areas where occupants need to manually secure themselves
Offers an added layer of manual control, but requires two actions to exit if the deadbolt is engaged.
LEBMS – Mortise Lock with Auto Deadbolt and Single Motion Egress
- Function: Motorized deadbolt auto-engages via credential or schedule
- Interior Lever: Retracts both latch and deadbolt in one motion
- Best For: Apartment entry doors, dorms, and other residential-style use cases
Meets life safety codes requiring single-motion egress while still offering full mortise security.
LEBMD – Mortise Lock with Auto Deadbolt, Dual Motion Egress
- Function: Same motorized deadbolt as LEBMS
- Interior Lever: Does not retract deadbolt—user must unlock it separately
- Best For: Secure storage rooms or high-security areas where independent release of the deadbolt is preferred
Great for facilities requiring intentional egress, but not typically residential.
Choosing the Right LE Model
When specifying a Schlage LE lock, consider:
- Do you need a deadbolt?
- Should the deadbolt be manual or motorized?
- Is single-motion egress required by code?
- What’s the intended user experience?
