The Command Access Technologies ML180ELCH 12V is a Grade 1 electrified mortise lock chassis for controlled-access commercial doors. Built as a retrofit solution for Schlage L9000 Series compatible mortise locks and trim, this 12V AC/DC, EL fail-safe, storeroom-function chassis allows a facility to integrate electric outside-lever locking without purchasing an entire new trim set when existing hardware is compatible.

Catalog Review – Product-Specific Notes

Mortise Retrofit and Package Scope

The ML180ELCH 12V is an electrified mortise chassis only, not a complete lockset with lever trim, cylinder and escutcheons. Confirm that the existing Schlage L9000-compatible mortise preparation, latch interface, handing and associated trim are suitable before ordering.

• Fail-safe operation: Verify the approved power-loss state against the door hardware schedule and life-safety requirements.
• Electrical preparation: Confirm the 12V factory model, permitted power source, wiring transfer, controller output and current rating with the supplied installation sheet.
• Mechanical completion: Verify latch engagement, compatible strike, free inside egress, any required mechanical key override and adequate door/frame clearance.

Key Features and Benefits

• Electrified storeroom mortise chassis: ML180 series provides electronic control of the outside lever, while the inside lever remains mechanically operable for free egress.
• Fail-safe (EL) function: Electrically locked / power-to-lock operation. In the specified fail-safe configuration, the outside lever is electrically secured and releases when power is removed. Confirm fail-safe operation is correct for the opening's approved hardware schedule.
• 12V AC/DC factory configuration: Order the specified voltage. This listing is for 12V, not the separate 24V version.
• Schlage L9000 retrofit compatibility: Designed for compatible Schlage L-Series mortise preps and trim, helping simplify retrofit projects without unnecessary changes to the opening when all components match.
• Grade 1 commercial platform: Rugged construction for demanding commercial and institutional doors.
• Chassis-only (CH): Replacement electrified lock chassis; specify compatible lever trim, cylinder, faceplate, strike, door prep and other required components separately.
• Field-reversible handing: Supports the manufacturer's field-handable mortise lock configuration.
• Inside free egress: The inside lever mechanically retracts the latch independently of the electrical outside-lever control.
• Options available separately: Manufacturer's ML1 series may support optional REX, latchbolt monitoring, door monitoring and current-reduction accessories when specifically ordered. Such options are not implied by this base SKU.

Technical Specifications

Recommended Applications

Retrofit installations at commercial offices, controlled storerooms, university and institutional facilities, maintenance rooms and managed-access interior openings where an existing Schlage L9000-style mortise lock system needs compatible electrified access control.

Fail-Safe vs. Fail-Secure

This ML180ELCH is the EL fail-safe version. It is not the ML180EU fail-secure version. The EL configuration electrically locks the outside lever when power is applied; the appropriate fail-safe behavior occurs when power is lost. The inside lever remains available for immediate egress. Select the proper function based on the access-control specification, security requirements, and applicable fire-door and life-safety codes.

Installation and Ordering Checklist

1. Confirm the approved schedule specifies ML180ELCH, 12V, EL fail-safe, storeroom chassis-only.
2. Check compatibility with the installed Schlage L9000 Series or equivalent compatible mortise trim, spindle, cylinder and latch/strike components.
3. Check door thickness, 2-3/4 in backset, mortise pocket, latch face, handing, clearance, and existing opening preparations against the factory template.
4. Provide a properly rated 12V AC/DC power supply, controller, relay and door power transfer; size for published startup/operating current and circuit requirements.
5. Use the manufacturer's wiring and testing procedures, then test controlled outside entry, power-loss behavior, mechanical key operation, latch engagement and inside free egress.
6. Do not assume an integrated REX contact, trim, cylinder, power supply, access reader or accessory is included without written confirmation for the specific SKU.
