Combine electrically controlled access with comprehensive door monitoring using the ACSI ACL9080EU/EL-RXDPS Electrified Mortise Lock Body.

Based on the Schlage L9080 mortise-lock platform, this configuration combines field-selectable Fail Safe / Fail Secure electrification with both a built-in Request-to-Exit (RX) switch and Door Position Switch (DPS).

The lock operates from 12/24VAC or DC and provides electronically controlled outside access while maintaining mechanical egress from the inside in the applicable L9080 configuration.

This listing is for the electrified mortise lock body with connector, RX monitoring, and DPS monitoring. Lever trim and cylinder are sold separately unless specifically stated.

Dual Monitoring Functions

The ACL9080EU/EL-RXDPS provides two important monitoring functions in one lock body:

RX – Request to Exit

and

DPS – Door Position Switch

Together, these allow an access-control system to determine both:

1. Whether someone is operating the inside trim to exit

2. Whether the door itself is open or closed

This provides much more complete door-status information than the standard electrified lock body alone.

RX – Request-to-Exit Monitoring

The built-in RX switch monitors use of the inside lever.

When the inside lever is operated, the RX switch changes state and sends a signal to the connected access-control system.

RX Can Be Used To

• Recognize authorized egress

• Shunt a door-forced-open alarm

• Log an egress event

• Signal a security console

• Coordinate access-control logic

• Integrate with other door-monitoring functions

Typical RX Sequence

1. Door is closed and secured

2. User operates the inside lever

3. RX switch changes state

4. Access-control system recognizes authorized egress

5. User exits

6. Door closes

7. System returns to its normal monitored condition

Important

The RX switch is a monitoring function.

It does not itself electrically unlock the exterior lever.

DPS – Door Position Switch

The DPS option monitors whether the door is open or closed.

ACSI's mortise-lock DPS system uses:

• A magnetic sensor incorporated into the mortise-lock assembly

• A corresponding magnet mounted behind the ASA strike

When the door closes and the lock approaches the strike, the magnetic relationship changes the status of the DPS circuit.

This allows the access-control system to monitor the actual position of the door.

DPS Can Help Identify

• Door closed

• Door open

• Door held open

• Door opened after authorized egress

• Door remaining open beyond the programmed time

The exact alarm and reporting behavior is determined by the connected access-control system.

RX + DPS Access-Control Monitoring

Combining RX and DPS provides valuable information about what is happening at the opening.

For example:

Authorized Egress

RX activates + DPS changes to open

The system can recognize that someone intentionally exited through the door.

Door Open Without RX

DPS changes to open without RX activation

Depending on system programming, this may be treated as a potential:

Door Forced Open

condition.

Door Remains Open

If the DPS continues indicating an open door beyond the programmed time, the access-control system may generate a:

Door Held Open

condition.

This makes the RXDPS configuration useful for monitored commercial and institutional openings.

Field-Selectable Fail Safe / Fail Secure

The ACL9080EU/EL-RXDPS allows the electrical locking function to be selected for the opening.

EU – Fail Secure / Power Unlock

Power Applied = Outside Lever Unlocked

Power Removed = Outside Lever Locked

During a power failure, the secure side remains locked.

Fail-secure operation is commonly used where maintaining security during loss of power is important.

EL – Fail Safe / Power Lock

Power Applied = Outside Lever Locked

Power Removed = Outside Lever Unlocked

During a power failure, the secure side unlocks.

Fail-safe operation may be required on certain openings depending on life-safety and emergency-release requirements.

Important Fail-Mode Selection

Fail-safe versus fail-secure operation must be selected according to:

• Building code

• Fire code

• Security requirements

• Egress requirements

• Access-control sequence

• Fire alarm requirements

• Authority Having Jurisdiction requirements

L9080-Style Electrified Storeroom Function

The ACL9080EU/EL-RXDPS is based on an electrified L9080 storeroom-type mortise-lock function.

Typical operation includes:

Outside Lever

Electrically locked or unlocked according to the selected EU/EL mode.

Inside Lever

Provides mechanical egress and activates the RX monitoring switch.

Door Position

Monitored through the integrated DPS sensor.

Key Cylinder

A compatible cylinder can provide mechanical override from the exterior.

Mechanical Key Override

A compatible mortise cylinder allows mechanical access when required.

The key can retract the latchbolt even when the exterior lever is electrically secured.

Important

Key operation does not necessarily change the electrical lock state.

After the key operation is completed, the lock continues to follow the selected electrical control logic.

12 / 24 VAC or DC Operation

The ACL9080EU/EL-RXDPS supports:

• 12VAC

• 12VDC

• 24VAC

• 24VDC

This provides flexibility when integrating the lock into commercial access-control systems.

Before installation, verify:

• Supply voltage

• Power-supply rating

• Wire gauge

• Wire distance

• Relay capacity

• Power-transfer requirements

Continuous-Duty Electrification

The lock is designed for:

Continuous-Duty Operation

This allows the electrified locking function to remain energized for extended periods when properly powered.

Applications include:

• Business-hours access control

• Scheduled locking and unlocking

• Controlled office entrances

• Secure rooms

• Stairwell control

• Institutional access-control systems

Access-Control Integration

The ACL9080EU/EL-RXDPS can integrate with compatible:

• Card readers

• Keypads

• Mobile credential systems

• Access-control panels

• Time schedules

• Remote release switches

• Building management systems

• Security-management systems

• Fire alarm interfaces

Comprehensive Door Monitoring

The RXDPS configuration can be combined with access-control software to monitor events such as:

• Credential accepted

• Door unlocked

• Inside lever operated

• Authorized egress

• Door opened

• Door closed

• Door forced open

• Door held open

This makes the lock particularly useful where detailed audit and door-status information is required.

Life-Safety Integration

ACSI Series 1500 electrified mortise locks are designed for integration with compatible life-safety systems.

A properly designed system may coordinate with:

• Fire alarm controls

• Emergency-release circuits

• Stairwell unlocking

• Access-control panels

• Security systems

The required behavior depends on the selected fail mode and applicable code requirements.

DPS Installation

The Door Position Switch relies on proper alignment between:

Sensor in Mortise Lock

and

Magnet at the Strike

The magnet is installed behind the compatible ASA strike so that the sensor can detect whether the door is in the closed position.

Proper alignment is essential for reliable door-status monitoring.
