Add access-control capability to a commercial mortise-lock opening with the ACSI ACL9080EU/EL Electrified Mortise Lock Body.

Based on the Schlage L9080 mortise lock platform, this electrified lock body provides field-selectable fail-safe or fail-secure operation from one versatile lock case.

The ACL9080EU/EL supports 12VAC, 12VDC, 24VAC, or 24VDC operation and is designed for commercial access-control applications where the outside trim must be electrically locked or unlocked while maintaining mechanical egress from the secure side.

This listing is for the electrified lock body only. Lever trim, cylinder, rose or escutcheon, and other finishing hardware are ordered separately unless specifically stated.

Field-Selectable Fail Safe / Fail Secure

One of the main advantages of the ACL9080EU/EL is the ability to select the required electrical locking mode for the opening.

EL – Fail Safe / Power Lock

In the Fail Safe configuration:

Power Applied = Outside Trim Locked

Power Removed = Outside Trim Unlocked

If power is lost, the outside trim becomes unlocked.

This function is commonly selected where the opening is required to unlock upon loss of electrical power.

EU – Fail Secure / Power Unlock

In the Fail Secure configuration:

Power Applied = Outside Trim Unlocked

Power Removed = Outside Trim Locked

If power is lost, the outside trim remains secured.

This configuration is frequently used where perimeter or room security must be maintained during a power failure.

Important

Fail-safe versus fail-secure selection should always be based on the opening's:

• Building code requirements

• Fire-rating requirements

• Egress requirements

• Security requirements

• Access-control sequence

• Authority Having Jurisdiction requirements

Storeroom-Type Electrified Operation

The ACL9080EU/EL is based around the L9080 storeroom-type mortise lock platform.

In a typical configuration:

• Inside lever provides normal egress

• Outside lever is electrically controlled

• Key cylinder can provide mechanical access when properly configured

• Latchbolt remains positively latched when the door is closed

This makes the lock well suited for controlled rooms where authorized electronic entry is required without compromising free egress.

12 / 24 Volt AC or DC Operation

The ACL9080EU/EL supports:

• 12VAC

• 12VDC

• 24VAC

• 24VDC

This provides flexibility when integrating the lock into existing or new access-control systems.

Always verify the supplied voltage and required current with the project wiring diagram and power supply before energizing the lock.

Continuous-Duty Operation

The electrification is designed for:

Continuous-Duty Applications

This allows the lock to remain electrically energized for extended access-control periods when properly powered.

Typical uses include:

• Business-hour unlocking

• Scheduled locking and unlocking

• Controlled office entrances

• Stair tower doors

• Restricted rooms

• Institutional access-control openings

Access-Control Integration

The ACL9080EU/EL can be controlled by compatible:

• Card readers

• Keypads

• Access-control panels

• Credential readers

• Time schedules

• Building management systems

• Remote switches

• Relays

A properly rated power supply and control relay should be used according to the system design.

Life-Safety System Integration

ACSI Series 1500 electrified mortise locks are designed to interface with compatible:

Life-Safety Systems

Depending on the selected fail mode and opening requirements, the lock can be incorporated into systems involving:

• Fire alarm control

• Emergency release

• Building access control

• Stairwell unlocking

• Security management

Final operation must comply with applicable building and life-safety codes.

Key Cylinder Override

When a compatible key cylinder is installed, the latchbolt may be momentarily retracted mechanically with the key even when the outside trim is electrically locked.

Important

When the lock is electrically unlocked, the outside trim generally cannot be electrically overridden into a locked condition by simply operating the key cylinder.

Verify the exact cylinder and function requirements before ordering trim.

Mortise Lock Construction

The ACL9080EU/EL uses a commercial mortise-lock case designed to install within the edge of the door.

Typical L9080-platform specifications include:

Backset: 2-3/4"

Door Thickness: Standard 1-3/4" commercial door application

Lock Type: Mortise

Function: Electrified Storeroom / Controlled Entry

Because this listing is for the lock body only, visible trim is selected separately.

Commercial Grade 1 Platform

The L9000-style mortise-lock platform is designed for demanding commercial and institutional use.

Typical applications include:

• Hospitals

• Schools

• Universities

• Government facilities

• Offices

• Data centers

• Pharmaceutical areas

• Secure storage rooms

• Stair tower openings

• Access-controlled commercial doors

Fire-Rated Applications

Compatible L9080-based mortise-lock configurations are available for listed fire-door openings.

Important

For a fire-rated opening, verify the complete assembly, including:

• Door

• Frame

• Lock case

• Electrification

• Lever trim

• Cylinder

• Power supply

• Access-control wiring

The complete opening must maintain the required listing.

Monitoring Options

ACSI offers several monitoring functions across its Series 1500 mortise-lock platform.

Available related options can include:

• RX / AE – Request to Exit / Authorized Egress

• Latchbolt monitoring

• Security monitoring

• Door position monitoring

• Key monitoring

ACL9080EU/EL-RX

If Request-to-Exit monitoring is required, order the related:
