Combine electronic access control with advanced lock and door monitoring using the ACSI ACL9080EU/EL-LMRXDPS Electrified Mortise Lock Body.

Designed around the Schlage L9080 mortise-lock platform, this configuration provides field-selectable Fail Safe / Fail Secure operation along with three monitoring functions:

• LM – Latch Bolt Monitor

• RX – Request to Exit

• DPS – Door Position Switch

The ACL9080EU/EL-LMRXDPS operates on 12/24VAC or DC and is designed for commercial access-control openings where the system needs to monitor not only authorized egress, but also whether the latchbolt is fully extended and whether the door is actually open or closed.

Three Monitoring Functions

The ACL9080EU/EL-LMRXDPS combines three separate monitoring functions in one electrified lock body.

LM – Latch Bolt Monitor

The Latch Bolt Monitor monitors:

Full extension of the main latchbolt

This provides the access-control system with feedback indicating whether the latchbolt has returned to its fully extended position.

LM can help determine whether the door is:

• Properly latched

• Not fully latched

• Mechanically held open

• Experiencing latch alignment problems

• Not fully secured after closing

This provides more detailed lock-status information than door-position monitoring alone.

RX – Request to Exit

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

When someone operates the inside trim to exit, the RX switch sends a signal to the connected access-control system.

RX Can Be Used To

• Recognize authorized egress

• Shunt door-forced-open alarms

• Log exit events

• Coordinate security-system logic

• Signal access-control software

• Distinguish authorized egress from forced entry

Important

The RX switch is a:

Monitoring Function

It does not itself electrically unlock the exterior lever.

DPS – Door Position Switch

The Door Position Switch monitors whether the door is physically:

• Open

• Closed

ACSI uses a magnetic sensor incorporated into the mortise-lock assembly that reacts to a corresponding magnet mounted behind the compatible ASA strike.

This eliminates the need for a separate conventional door-position contact in many applications.

DPS Can Help Identify

• Door closed

• Door open

• Door held open

• Door opened after authorized egress

• Door remaining open beyond the programmed time

LM vs. DPS

These two monitoring functions provide different information.

DPS

Answers:

Is the door physically open or closed?

LM

Answers:

Is the main latchbolt fully extended?

A door can potentially be physically closed without the latchbolt being fully engaged.

Using both monitoring functions allows the access-control system to identify this condition.

Complete RX + LM + DPS Monitoring

Together, the three sensors allow sophisticated door-state monitoring.

Normal Secured Door

• DPS indicates door closed

• LM indicates latchbolt fully extended

• RX inactive

The opening is closed and latched.

Authorized Egress

• RX activates

• LM changes as latch retracts

• DPS changes when door opens

The access-control system can recognize a normal authorized exit.

Door Closed but Not Latched

• DPS indicates closed

• LM does not indicate full latch extension

The door may be physically against the frame but not properly latched.

This can help identify:

• Door alignment problems

• Strike alignment issues

• Obstructions

• Binding hardware

• Door closer problems

Door Forced Open

Depending on system programming:

• DPS changes to open

• RX did not activate

• No authorized entry event occurred

The access-control system may interpret this as a:

Door Forced Open

condition.

Door Held Open

If DPS remains in the open state longer than the programmed time, the access-control system may generate a:

Door Held Open

alarm.

Field-Selectable Fail Safe / Fail Secure

The electrical locking function can be configured according to the requirements of the opening.

EU – Fail Secure / Power Unlock

Power Applied = Outside Lever Unlocked

Power Removed = Outside Lever Locked

During a loss of power, the exterior side remains secured.

Fail-secure operation is commonly used where maintaining security during power failure is required.

EL – Fail Safe / Power Lock

Power Applied = Outside Lever Locked

Power Removed = Outside Lever Unlocked

During a loss of electrical power, the outside lever unlocks.

Fail-safe operation may be required for certain life-safety applications.

Important

Fail mode should be selected based on:

• Building code

• Fire code

• Life-safety requirements

• Security requirements

• Fire alarm sequence

• Access-control sequence

• Authority Having Jurisdiction requirements

Electrified Storeroom-Type Operation

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

Typical operation includes:

Outside Lever

Electrically controlled according to the selected EU or EL mode.

Inside Lever

Provides mechanical egress and activates the RX monitoring switch.

Main Latchbolt

Monitored through the LM switch.

Door Position

Monitored through the DPS magnetic sensor.

Key Cylinder

A compatible cylinder can provide mechanical override from the exterior.

Mechanical Key Override

When equipped with the appropriate cylinder, the key can mechanically retract the latchbolt even if the outside lever is electrically locked.

Key operation does not necessarily change the electrical state of the lock.

After key operation, the lock continues to follow the access-control command.

12 / 24 VAC or DC Operation

The ACL9080EU/EL-LMRXDPS supports:

• 12VAC

• 12VDC

• 24VAC

• 24VDC

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

Always verify:

• Power-supply voltage

• Power-supply capacity

• Wire gauge

• Wire distance

• Power-transfer requirements

• Relay ratings

Continuous-Duty Electrification

The lock is designed for:

Continuous-Duty Operation

This allows the electrified locking function to remain energized for extended periods when supplied with the proper voltage and power.

Typical applications include:

• Business-hours access control

• Scheduled unlocking

• Stairwell control

• Secure offices

• Controlled rooms

• Institutional access systems

Access-Control Integration

The ACL9080EU/EL-LMRXDPS can integrate with compatible:

• Access-control panels

• Card readers

• Keypads

• Mobile credential readers

• Time schedules

• Security-management systems

• Building-management systems

• Fire alarm interfaces

• Remote release controls

Advanced Door Status Monitoring

With RX, LM, and DPS signals connected to an access-control panel, the system can potentially monitor events such as:

• Credential accepted

• Door unlocked

• Inside lever operated

• Authorized egress

• Latchbolt retracted

• Latchbolt fully extended

• Door opened

• Door closed

• Door closed but not latched

• Door forced open

• Door held open

Actual reporting depends on the access-control panel and programming.

Life-Safety Integration

ACSI Series 1500 electrified mortise locks are designed to interface with compatible life-safety systems.

Applications may include:

• Fire alarm control

• Emergency unlocking

• Stairwell unlocking

• Access-control systems

• Security systems

The final system sequence must comply with applicable codes and the requirements of the complete opening.
