ACSI ACSI-M1510M-AE-1-ML2055-DSA-625-RH-LC – Frequently Asked Questions

1) What happens to this ACSI 1500 Series electric mortise lock when the power drops?
The M1510M-AE fail safe function unlocks on power loss. With power applied the outside trim is locked (storeroom function); remove power and the lockset reverts to passage, so the outside lever retracts the latch. That is what makes it suitable for stairtower doors and controlled egress paths. On the motor controlled version the fail safe/fail secure orientation is user selectable in the field, so the same lock can be flipped to lock on power loss instead.
2) Will this mortise lock fit a 1-3/4 inch door with a standard ANSI mortise pocket?
Yes, it is built for 1-3/4 inch doors on a 2-3/4 inch backset. The case measures 5-7/8 x 4 x 15/16 inches and the front is 8 x 1-1/4 x 3/32 inches with an ANSI straight lip strike at 4-7/8 x 1-1/4 inches, 1-1/8 inch lip. Trim projects 2-9/16 inches and the rose is 2-1/4 by 2-1/4 inches. Confirm your existing pocket matches the 8 inch front before you cut.
3) Do I have to order this lock handed, or can it be field reversed?
Handed. The M1510M-AE-1-ML2055 is ordered as right hand or left hand and both are offered, so determine handing from the secure side before ordering. Get it wrong and the lever and latch orientation will not suit the opening.
4) Does a cylinder come with this ACSI electrified Corbin Russwin mortise lock?
No. It ships less cylinder (LC), so you supply the mortise cylinder to match your keyway and master key system. Spacing is 3-5/8 inches lever to cylinder and 2-7/16 inches lever to thumbturn, which is what you check when laying out the trim prep.
5) What does the Authorized Egress (AE) option actually do on this lock?
AE is request to exit. The lock signals your access control panel when someone turns the inside lever to leave, so egress from the secure side is recognized rather than treated as a forced door. There is also a latchbolt monitor, which reports whether the latch is actually engaged in the strike. Together those two outputs are what let the opening tie into a life safety or alarm system.
6) Is this lock code compliant for a school or hospital stairwell door?
It is UL Listed, California State Fire Marshal approved, and meets ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 plus A117.1 accessibility. It is ADA compliant with a 4-1/2 inch lever. ACSI lists it for offices, schools, hospitals and hotels, and the fail safe unlocking on power loss is what conforms to life safety code on a stairtower door.
7) Will this latch into the strike already in my frame?
The latchbolt is a 2-piece mechanical type with an anti-friction insert, 5/8 x 1 inch face with a 3/4 inch throw, and a 9/16 inch auxiliary deadlatch. It comes with an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with a 1-1/8 inch lip. If your frame already has a standard ANSI 4-7/8 strike prep, it drops in; a smaller T-strike or non-ANSI prep will need reworking.
8) What voltage and current does this electrified mortise lock draw?
It runs on 12 to 24V, AC or DC, drawing 250mA inrush and 10mA holding. Continuous duty rated, so it can sit energized on an access control circuit all day. Size the power supply for the inrush, not the holding current, if you are running several locks off one supply.
9) 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 this is, gives you user selectable fail safe or fail secure operation in the field and low power consumption, so one part number covers either behavior and the holding current stays at 10mA. Solenoid locks are fixed in their fail mode. If you are standardizing across a building with a mix of stairtower and controlled-area doors, the motor controlled lock is the one that lets you keep a single SKU on the shelf.
10) What lever and finish choices are there on the ACSI 1510M-AE Corbin Russwin mortise lock?
Trim is the DS lever with the A rose, in 625 bright chrome or 626 satin chrome, each in right or left hand. The rose is 2-1/4 inches square and the lever is 4-1/2 inches. If the rest of your openings are on satin chrome Corbin Russwin 2000 Series trim, the 626 matches without a visual break in the corridor.
11) Is this the same as a standard mechanical Corbin Russwin ML2055 office lock?
Not quite. It starts as a Corbin Russwin 2000 Series mortise lever lock and is modified by ACSI for electric control. Mechanically the ML2055 trim, 2-3/4 inch backset and 8 inch front carry over, but the electrified version adds motor control, request to exit signaling and a latchbolt monitor, and it needs 12 to 24V run to the door through a hinge or power transfer. If you only need a keyed office function with no access control, a plain mechanical mortise lock is the cheaper and simpler part.
12) What is the hub made of on this electric mortise lock, and how heavy is the front?
The hub is steel at 5/16 inch, and the front is heavy gauge steel. That matters on high-traffic institutional openings where the lever takes constant use; the steel hub is what resists wear and rack at the spindle.
