ACSI M1520M AE-1-L9070 Modified Lock Body

Product Description

The ACSI M1520M AE-1-L9070 is an electrified modified lock body based on the heavy-duty Schlage L9070 commercial mortise lock chassis. Factory-modified by Access Control Systems Incorporated (ACSI), this unit integrates an internal Request to Exit (RX / AE-1) monitoring switch to provide real-time latch/bolt monitoring and door status feedback to an electronic access control or security system.

Designed for demanding commercial and institutional applications, the M1520M AE-1 retains all the structural integrity and physical security of the Schlage L Series mortise lock. The built-in request-to-exit switch signals system controllers when the inside lever is depressed, allowing for seamless integration with alarm bypass, door position tracking, and access event logging.

Product Features

  • Built-in Request to Exit Switch (AE-1 / RX): Integrated microswitch monitors the movement of the interior lever to trigger egress signals, shunt door alarms, or notify control systems automatically.

  • Schlage L9070 Base Lock Body: Constructed around the industry-standard Schlage L Series Grade 1 mortise chassis for exceptional physical durability and long operational life.

  • Classroom / Security Function (L9070): Latchbolt retracted by lever from either side unless the outside lever is locked by key from the outside. Inside lever always allows free egress.

  • Seamless Access Control Integration: Ideal for pairing with electronic keypads, card readers, magnetic locks, and facility management software.

  • Maintains Factory UL Listing: Precision modified by ACSI to retain standard fire door certifications and commercial door preparation requirements.

ACSI ACSI-M1520M-AE-1-L9070L – Frequently Asked Questions

1) Will the ACSI M1520M-AE-1-L9070L electrified mortise lock lock or unlock if the power drops?
It locks. The 1520M AE function is fail secure: outside trim is unlocked while power is applied and locks when power is removed, so a power failure leaves the secure side locked. The inside lever always retracts the latch for free egress, and the Request to Exit switch signals the access control system that someone exited. Worth knowing before you order: the fail safe/fail secure operation on these motor controlled locks is user selectable in the field, so the same lock can be set to unlock on power loss if the opening is on an egress path that requires it.
2) What door thickness and backset does the ACSI M1520M-AE mortise lock need?
Single thickness only: 1-3/4 inch doors, with a 2-3/4 inch backset. That is the standard commercial door and the standard mortise backset, so it drops into a normal mortise prep, but it will not work on a 1-3/8 inch interior door. The mortise case measures 4-7/16 x 6-1/16 x 1 inches and the front is 1-1/4 x 8 x 7/32 inches, so check your existing pocket and edge cutout against those before you commit.
3) Will the ACSI M1520M-AE mortise lock latch into the strike already in my frame?
Depends on what is in the frame now. The lock throws a 3/4 inch stainless steel latch with an anti-friction tongue, and it ships as a curved lip strike, 4-7/8 x 1-1/4 inches with a 1-3/16 inch lip. If your frame is prepped for the standard 4-7/8 inch ANSI mortise strike, it drops straight in. If the existing strike is a flat lip or a T-strike, or the lip length does not reach past the frame stop, plan on changing the strike out. The 3/4 inch throw is what a mortise lock latch normally gives you, so latch engagement is not the variable here, the strike opening is.
4) Do I have to order the ACSI M1520M-AE mortise lock handed for a left or right hand door?
No. Handing is reversible in the field, so one part number covers left hand, right hand, and reverse bevel openings. That is the reason a property manager or facilities group can stock a single lock across a building instead of splitting inventory two ways. What you do have to specify is trim: four lever designs (03, 06, 07, 17) and two rose choices, A wrought rose or L full face escutcheon, for eight orderable combinations in all.
5) Does the ACSI M1520M-AE-1-L9070L mortise lock come with a cylinder?
No cylinder is included. It is supplied less conventional cylinder, so you add a mortise cylinder in your own keyway and keying, which is usually what a locksmith or an institution on a master key system wants anyway. Order a conventional mortise cylinder with a Schlage L Series cam, and size the length to the trim you picked, since a full face L escutcheon sits differently than a wrought A rose. Cylinder to lever spacing on the case is 3-7/8 inches, and lever to thumbturn hub is 2-11/16 inches.
6) What voltage and current do I need to run to an ACSI 1500 Series motor controlled mortise lock?
12 to 24VAC or VDC, drawing 250mA inrush and only 10mA holding. The low holding current is the practical point: a motor controlled lock pulls current briefly to drive the motor, then settles, so you can put several openings on one modest power supply where solenoid style electric locks would force you into a much bigger supply. It is continuous duty rated, so it can sit energized indefinitely. The monitor switch is rated 2A at 30VDC and 3A at 125VAC.
7) Do I still need a separate request to exit device with this electrified mortise lock?
Not for the lock itself. Authorized egress is built in: the Request to Exit function reports through the lock when the inside lever is turned, so the access control panel sees a legitimate exit and does not log a forced door. That saves running a REX motion sensor over the opening on a card reader door. It also interfaces with life safety systems, which is how you tie the opening into a fire alarm release. You still wire the lock and its REX back to your panel, and you still need a power supply and, if you want position status, to land the monitor switch.
8) Is the ACSI M1520M-AE mortise lock Grade 1 and can it go on a fire rated door?
ANSI/BHMA A156.13-2017 Series 1000, Grade 1 for both operational and security, plus ASTM F476-76 Grade 40. It is UL Listed, California State Fire Marshal approved, and tested to UL 10C and CAN/ULC-S104, which are the positive pressure fire door standards, so it belongs on a labeled opening. It is also ADA compliant and complies with ICC A117.1, which matters because the lever is the operable part an accessibility inspector looks at. For a hospital, school, or government facility standardizing hardware, that is the full stack of ratings usually written into the spec.
9) Can the ACSI M1520M-AE-1-L9070L replace an existing Schlage L Series mortise lock without redoing the door?
That is exactly what it is: a Schlage L Series mortise lock modified by ACSI for motor controlled electrified operation. It keeps the L Series case and the 2-3/4 inch backset on a 1-3/4 inch door, with a 4-7/16 x 6-1/16 x 1 inch case and a 1-1/4 x 8 x 7/32 inch front. If the opening already has an L Series lock, the mortise pocket and edge prep carry over. The new work is electrical: you need a power transfer into the door leaf and 12 to 24V run to the lock, which a mechanical L Series never had.
10) What is the difference between the A wrought rose and the L full face escutcheon on the ACSI 1500 Series mortise lock?
The A rose is a compact round trim, 2-1/8 inches across, mounting the lever alone with the cylinder separate on the door face. The L escutcheon is a full face plate that covers the lever and cylinder area together, which is the usual pick when you are covering an older prep or an oversize hole from previous hardware, and it is what most Schlage L Series openings in institutional buildings already carry. Function is identical either way. Choose on appearance and on what the existing door face looks like. Either trim projects 2-13/16 inches off the door, and the lever is 4-3/4 inches.
11) Is the ACSI 1500 Series electrified mortise lock suitable for a high traffic commercial entrance?
Yes. It is a commercial Grade 1 lock under ANSI/BHMA A156.13-2017 Series 1000 for both operational and security, with a stainless steel latch and anti-friction tongue, and the electrification is continuous duty rated so it can hold energized all day on an unlocked schedule. The anti-friction tongue matters on an entrance with a closer and any stack pressure, since it eases the latch past the strike lip instead of dragging. Office and entry function, so the outside lever is the controlled side and the inside lever always exits.
