ACSI ACSI-M1520M-AE-1-ML2055-LL-626 – Frequently Asked Questions

1) Which mortise lock bodies does the ACSI M1520M-AE-1-ML2055-LL work with?
It is built on the Corbin Russwin 2000 Series mortise lock body. ACSI takes a Corbin Russwin 2000 Series classroom mortise lock body and modifies it for electric control, so the prep, case size and strike are Corbin Russwin 2000 Series. It will not drop into a Schlage L, Sargent 8200 or Yale 8800 pocket.
2) What does fail secure with authorized egress mean on this ACSI electrified mortise lock?
Fail secure means the outside (secure side) lever is controlled by power: energize to unlock, de-energize to keep it locked. The inside lever always retracts the latch mechanically, so free egress is never interrupted. Authorized egress adds a request-to-exit signal, so when someone leaves through the door the access control system sees it and does not read it as a forced door.
3) Can I use a fail secure electric mortise lock on a stairwell or fire-rated door?
This is the application ACSI builds the 1500 Series for: stairtower doors and controlled areas where the opening has to both lock and latch. The lock is UL Listed, California State Fire Marshal approved and continuous duty rated. Because it is fail secure with a mechanically free inside lever, remote locking and unlocking happens without defeating egress. Confirm the specific opening against your local code and the door's label before you specify it.
4) Should I choose the motor-controlled or the solenoid-controlled version of the ACSI 1500 Series?
ACSI offers the 1500 Series electric mortise locks in both motor-controlled and solenoid-controlled versions. The M1520M here is the motor-controlled one, which pulls power only while the motor cycles the lock and is the choice where you are running many doors off one supply or want the quieter, lower-draw option. A solenoid version holds a coil energized and reacts instantly, which some integrators prefer for high-cycle turnstile-style traffic. Both conform to life-safety codes for remote locking and unlocking.
5) What lever and rose design does the ML2055-LL version come with?
The LL suffix is the Corbin Russwin L lever on the L rose, and the ML2055 is the office/entry function of the 2000 Series. If you are matching other openings in the building, the lever and rose design has to be specified the same way, since the trim design is fixed in the part number rather than ordered separately.
6) Do I get a complete lockset or just the electrified lock body?
ACSI supplies this as a Corbin Russwin 2000 Series lock body modified for electric operation, catalogued as a lock part/component with the L rose and L lever trim called out in the part number. Plan the job so the power transfer to the door, the power supply and the access control interface for the request-to-exit signal are ordered alongside it, since none of those are part of the lock.
7) What finishes is the ACSI M1520M-AE-1-ML2055-LL mortise lock available 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. For a stairwell or back-of-house run that is being standardized, 626 and 630 are the usual specs; the brass and bronze finishes are there for matching existing front-of-house trim.
