ACSI ACSI-M1520M-AE-1-ML2055-LWA-626-LC – Frequently Asked Questions

1) Does the ACSI M1520M-AE electrified mortise lock lock or unlock when power fails?
As shipped in the AE fail secure configuration, outside trim is unlocked when power is applied and locked when power is removed, so the lockset locks on a power failure. The inside lever always retracts the latch for free egress. Because it is a motor controlled lock, fail safe/fail secure operation is user selectable in the field, so the same lock can be flipped to unlock on power loss if the opening calls for it.
2) Will this ACSI 1500 Series mortise lock fit my door and existing mortise prep?
It is built for 1-3/4 inch doors with a 2-3/4 inch backset. The case measures 5-7/8 x 4 x 15/16 inches and the heavy gauge steel front is 8 x 1-1/4 x 3/32 inches. Trim spacing is 3-5/8 inches lever to cylinder and 2-7/16 inches lever to thumbturn, with a 2-1/4 inch rose and 2-1/2 inch projection. That is standard Corbin Russwin 2000 Series mortise geometry, so it drops into an opening already prepped for that case.
3) Do I need to order a cylinder separately for the M1520M-AE-1-ML2055-LC?
Yes. The LC suffix means less cylinder, so no cylinder is supplied. You furnish a mortise cylinder to match your keying, which is what most facilities want when they are keying into an existing master system. Trim spacing allows 3-5/8 inches from lever to cylinder.
4) 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. That low holding current means several openings can share a modest access control power supply. The built in monitor switch is rated 2A at 30VDC or 3A at 125VAC.
5) What does Authorized Egress (AE) actually do on this lock?
AE is request to exit. Turning the inside lever signals the access control panel that someone is leaving, so the door position switch can be shunted and no alarm is raised on a valid exit. It is what you want on stairtower and controlled area doors that are monitored, and it lets the lock tie into life safety systems.
6) Is this ACSI mortise lock Grade 1 and ADA compliant for a school or hospital corridor?
Yes on both counts. It carries ANSI/BHMA A156.13 Series 100 operational and security Grade 1, is UL Listed, California State Fire Marshal approved, and meets A117.1 accessibility. The 5-1/8 inch lever is ADA compliant. It is specified for offices, schools, hospitals and hotels.
7) Will this lock latch into the strike already in my frame?
The supplied strike is 4-7/8 x 1-1/4 inches with a straight lip and 1-1/8 inch lip projection, which is the common commercial mortise strike size. Latch throw is 3/4 inch with a 9/16 inch auxiliary deadlatch, and the latchbolt itself is 5/8 x 1 inch, two piece mechanical with an anti-friction insert. If your existing frame is cut for a 4-7/8 inch ANSI mortise strike, the lock will latch without frame work.
8) Do I have to specify handing on this ACSI electric mortise lock?
No handing to call out. The lock is field reversible, so one part number covers left and right hand openings and a stocked spare works on any door in the building.
9) What lever, rose and finish combinations can I get on the ACSI M1520M-AE Corbin Russwin mortise lock?
Four Corbin Russwin lever designs (LW, NS, PS, RW) paired with A, M or N rose designs, in seven finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright polished chrome, 626 satin chrome and 630 satin stainless. If you are matching existing doors in the building, pick the lever and rose already on them and hold the same finish number.
10) Should I use an electric mortise lock like this or an electric strike for a stairtower door?
The 1500 Series electric mortise lock is for openings where both locking and latching have to stay intact, like stairtowers and controlled areas, and where you also want the lock itself monitored and signalling request to exit. An electric strike releases the frame side and does not give you inside lever request to exit or selectable fail safe/fail secure at the door. Where the door must always latch and you need life safety interface, the mortise lock is the right call.
11) What is the 1 in M1520M-AE-1 and how does it change the lock's behavior?
The 1 designates standard control: the electric control locks the outside, secure side trim. Inside trim stays free at all times. If you need control on the opposite side of the opening, that is a different locking option, so confirm which face is your secure side before ordering.
