Add electrically controlled access and integrated door-position monitoring to a commercial mortise-lock opening with the ACSI ACL9080EU/EL-DPS Electrified Mortise Lock Body.

Based on the Schlage L9080 mortise-lock platform, this configuration combines field-selectable Fail Safe / Fail Secure electrification with ACSI's integrated DPS Door Position Sensor.

The DPS system monitors whether the door is open or closed through a magnetic sensor incorporated into the mortise lock and a corresponding magnet positioned behind the ASA strike.

This configuration is ideal for commercial access-control systems that need both electrical control of the outside lever and reliable door-position status without adding a separate surface-mounted door contact.

DPS – Door Position Sensor

The DPS suffix adds integrated:

Door Position Monitoring

ACSI's DPS system uses a magnetic sensor inside the mortise-lock assembly.

A magnet positioned behind the compatible ASA strike interacts with the lock-mounted sensor when the door reaches the closed position.

This allows the connected access-control system to determine whether the door is:

• Closed

• Open

• Held open

• Not fully returned to the secure position

Integrated Door Monitoring

Because the sensor is integrated into the mortise-lock assembly, the DPS option can eliminate the need for a separate exposed surface-mounted magnetic contact in many applications.

This provides a cleaner installation while still allowing the access-control system to monitor door status.

Typical DPS Operation

A properly configured system may operate as follows:

1. Door is closed

2. Lock-mounted magnetic sensor detects the strike magnet

3. DPS indicates the door is in the closed position

4. User opens the door

5. Sensor moves away from the strike magnet

6. DPS changes state

7. Access-control system recognizes the door as open

8. Door closes and DPS returns to the closed-door state

The access-control panel determines how the DPS signal is interpreted and reported.

Door Held Open Monitoring

When used with a compatible access-control system, the DPS signal can help create:

Door Held Open Alerts

For example, if the door remains open longer than the programmed allowable time, the system can generate an alarm or notification.

This is useful for:

• Secure offices

• Server rooms

• Hospitals

• Schools

• Government facilities

• Controlled storage areas

Door Forced Open Applications

DPS can also be used as part of a:

Door Forced Open Monitoring System

If the door changes from closed to open without the expected authorization event, the access-control panel can be programmed to treat the event as an alarm.

The exact behavior depends on the connected access-control system and other installed monitoring equipment.

Field-Selectable Fail Safe / Fail Secure

The ACL9080EU/EL-DPS allows the electrical operating mode to be selected for the opening.

EU – Fail Secure / Power Unlock

Power Applied = Outside Lever Unlocked

Power Removed = Outside Lever Locked

If electrical power is lost, the outside side remains secured.

This configuration is commonly selected where security must be maintained during a power failure.

EL – Fail Safe / Power Lock

Power Applied = Outside Lever Locked

Power Removed = Outside Lever Unlocked

If electrical power is lost, the outside side becomes unlocked.

This configuration may be required for certain life-safety or emergency-release applications.

Important

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

• Building code requirements

• Fire code requirements

• Security requirements

• Egress requirements

• Access-control sequence

• Life-safety requirements

• Authority Having Jurisdiction requirements

L9080-Style Electrified Storeroom Function

The ACL9080EU/EL-DPS is based on the commercial L9080 storeroom-type function.

Typical operation includes:

Outside Lever

Electrically controlled according to the selected EU or EL mode.

Inside Lever

Provides mechanical egress.

Key Cylinder

A compatible mortise cylinder can provide mechanical outside access.

Door Position

Monitored through the integrated DPS sensor.

Mechanical Key Override

When fitted with a compatible mortise cylinder, the latchbolt can be mechanically retracted with a key when required.

This provides authorized mechanical access even when the outside lever is electrically secured.

Electrical operation resumes according to the access-control system after key operation.

12 / 24 VAC or DC Operation

The ACL9080EU/EL-DPS can operate from:

• 12VAC

• 12VDC

• 24VAC

• 24VDC

This provides flexibility for integration into new or existing commercial access-control systems.

Before installation, verify:

• Available voltage

• Power-supply capacity

• Wire gauge

• Wire distance

• Control relay rating

• Power-transfer requirements

Continuous-Duty Operation

ACSI's Series 1500 electrified mortise-lock platform is designed for:

Continuous-Duty Operation

This allows the electrification to remain energized for extended periods when properly powered.

Typical applications include:

• Scheduled access periods

• Business-hours locking

• Business-hours unlocking

• Controlled office entrances

• Secure rooms

• Institutional access control

Access-Control Integration

The ACL9080EU/EL-DPS can be integrated with compatible:

• Card readers

• Keypads

• Mobile credential readers

• Access-control panels

• Time schedules

• Remote switches

• Control relays

• Building management systems

• Security management systems

The DPS signal connects to an appropriate monitoring input on the access-control system.

DPS vs RX

The ACL9080EU/EL-DPS does not include RX Request-to-Exit monitoring unless separately specified.

DPS

Monitors:

Door Position

RX

Monitors:

Operation of the Inside Trim / Authorized Egress

If both functions are required, use the appropriate:

ACL9080EU/EL-RXDPS

configuration.

DPS vs LM

The DPS option should also not be confused with:

LM – Latch Bolt Monitor

DPS

Monitors whether the:

Door is open or closed

LM

Monitors whether the:

Main latchbolt is fully extended

These are separate monitoring functions.

Life-Safety Integration

ACSI electrified mortise locks can be incorporated into compatible:

• Fire alarm systems

• Emergency-release circuits

• Stairwell control systems

• Access-control systems

• Building security systems

Final system behavior depends on the selected fail mode and the requirements of the complete opening.
