ACSI ACSI-M1520M-AE-1-ML2055-ASA-605-LC – Frequently Asked Questions

1) Does the ACSI M1520M-AE mortise lock unlock or stay locked when power is lost?
On the motor-controlled 1500 Series lock, fail safe and fail secure operation is field selectable, so you set the behavior at install. As configured in the M1520M-AE description, outside trim is locked when power is applied and unlocked when power is removed (storeroom when energized, passage on power loss). If your stairtower or controlled-area spec calls for the opposite behavior, the motor-controlled lock can be set to it without ordering a different part.
2) Will this ACSI electrified mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
That is exactly the prep it wants. The 1500 Series mortise lock is built for 1-3/4 inch door thickness with a 2-3/4 inch backset, which is the standard commercial mortise prep. Case measures 5-7/8 x 4 x 15/16 inches with an 8 x 1-1/4 x 3/32 inch front, so it drops into a standard ANSI mortise pocket. Trim projects 2-5/8 inches off the face.
3) Does a cylinder come with the ACSI M1520M-AE-1-ML2055 mortise lock?
No. Every configuration is Less Cylinder (LC), so you supply the mortise cylinder separately. That is usually what a locksmith or facility wants anyway, since it lets you key the lock into an existing master system. Plan on a mortise cylinder to match your keyway and a cam that suits the Corbin Russwin 2000 Series case.
4) Will the existing strike work, and what strike does this ACSI mortise lock use?
It uses an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with a 1-1/8 inch lip. The latchbolt is a 5/8 x 1 inch two-piece mechanical latch with an anti-friction insert and 3/4 inch throw, plus a 9/16 inch auxiliary deadlatch. If your frame already carries a standard 4-7/8 ANSI strike prep, the latch lines up; a T-strike or an older non-ANSI lip will need the frame reworked or the matching strike swapped in.
5) What power supply do I need for the ACSI 1500 Series motor-controlled mortise lock?
It runs on 12 to 24V AC or DC, drawing 250mA inrush and only 10mA holding, and it is continuous duty rated. The low holding current means several openings can share a modest access control power supply. Size the supply for the inrush across however many locks release at once. The built-in monitor switch is rated 2A at 30VDC or 3A at 125VAC.
6) What does Authorized Egress (AE) mean on this Corbin Russwin 2000 Series electric mortise lock?
Authorized Egress is the request-to-exit function. Turning the inside lever signals the access control system that someone is leaving, so the system can shunt the alarm instead of treating it as a forced door. Free mechanical egress from the inside lever is always available regardless of power state, which is how these locks stay within life-safety code on stairtowers and controlled areas.
7) Is the ACSI M1520M-AE mortise lock ADA compliant and Grade 1?
Yes on both counts. It carries ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, and meets A117.1 accessibility code with a 4-1/2 inch lever. It is also UL Listed and California State Fire Marshal approved. That combination is what institutional and government specs normally ask for on office, school, hospital and hotel openings.
8) Do I have to specify handing when ordering this ACSI electric mortise lock?
No. The lock is field reversible, so one part number covers left and right hand openings and you set the hand on site. That matters for a property manager stocking spares across a building: one lock covers every door in the run instead of carrying both hands.
9) What lever, rose and finish choices do I pick from on the ACSI M1520M-AE-1-ML2055?
Two lever designs, AS and CS, each paired with either an A or M rose, across six finishes: 605 bright brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome and 630 satin stainless. That is 24 orderable combinations. Roses are 2-1/4 inches square in footprint (2-1/4 wide by 2-1/4 long), so matching an existing rose diameter on adjacent doors is worth checking before you standardize a floor.
10) Should I use a motor-controlled electric mortise lock or a solenoid one?
ACSI's 1500 Series comes both ways. The motor-controlled version, which is what the M1520M is, gives you user-selectable fail safe or fail secure in the field and draws very little current while holding, so it suits stairtowers and access-controlled openings where the life-safety behavior may need to change or where you are running many locks off one supply. A solenoid-controlled version of the series is the alternative when the fail mode is fixed by spec and you do not need to switch it.
11) What does the -1 locking option mean on the M1520M-AE-1?
The 1 designates standard control: the electrical function locks and unlocks the outside, secure side trim only. Inside trim is never controlled electrically, which is what preserves free egress. When you are writing the order, that digit is the difference between controlling the outside lever and a configuration that behaves differently, so keep it in the part number.
12) Can this ACSI lock tie into a fire alarm or life safety system?
Yes. The 1500 Series is built to interface with life safety systems, and the monitor switch (rated 2A at 30VDC, 3A at 125VAC) reports door or latch status back to your panel. Combined with the request-to-exit signal from the inside lever, you get both egress notification and position monitoring from the one lock body rather than adding separate hardware to the frame.
