ACSI ACSI-M1520M-AE-1-MOCN-8808-626-LC – Frequently Asked Questions

1) What happens to an ACSI 1520M mortise lock when the power goes out?
Wired fail secure, the outside trim is locked while power is applied (storeroom function when energized) and unlocks when power is removed, so the opening reverts to passage on a power failure. The motor-controlled version is user selectable between fail safe and fail secure in the field, so you can flip the behavior without swapping the lock.
2) Will the ACSI M1520M mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset?
Yes. The 1500 Series electric mortise lock is built for 1-3/4 inch doors with a 2-3/4 inch backset, and the case measures 4-1/8 x 1 x 6-1/16 inches with an 8 x 1-1/4 inch front. Projection off the door face is 3 inches. If your existing mortise pocket is cut for a different thickness or backset, this one will not drop in.
3) Does the ACSI 1520M lock come with a cylinder?
No. It ships less cylinder (LC), so you supply the mortise cylinder to match your keyway and keying system. That is usually what a locksmith or facility wants anyway, since the lock can then be keyed into an existing master system.
4) What does the Authorized Egress option on the ACSI 1520M actually do?
Authorized Egress is ACSI's request-to-exit function. Turning the inside lever signals the access control system that someone is leaving legitimately, so the door can be released without triggering a forced-door alarm. The lock is built to interface with life safety systems, which is why it is used on stairtower and controlled-area openings.
5) Can the ACSI 1520M electrified mortise lock go on a fire rated stairwell door?
It is UL Listed, California State Fire Marshal approved, and UL/cUL fire rated up to 3 hours. It also meets ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and A156.115, and is listed ADA compliant. Note that as a fail secure lock it unlocks on power loss, so confirm that behavior matches your stair re-entry strategy.
6) 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 locks can share a modest supply, but size the supply for the inrush of all locks that could actuate at once. There is also a monitor switch rated 2A at 30VDC or 3A at 125VAC for door position or lock status reporting.
7) Will the ACSI 1520M latch into my existing mortise strike?
The latchbolt is a stainless steel one-piece anti-friction type with a 3/4 inch throw, and the supplied strike is a curved lip type at 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip. If your frame is already prepped for a standard 4-7/8 inch ANSI mortise strike, the new strike drops into the same cutout; a box strike or T-strike frame prep will need modification.
8) Do I have to order the ACSI 1520M by hand?
No. Handing is field reversible, so one lock covers left and right hand openings. That is useful for a property manager stocking spares across a building instead of carrying both hands.
9) Which lever and escutcheon designs and finishes does the ACSI M1520M-AE Yale 8800 Series lock come in?
Four Yale lever designs are offered: MO (Monroe), PB (Pacific Beach), PN (Pinehurst) and VI (Virginia). Each pairs with either the CN (Camden) or R (Copenhagen) escutcheon. Finishes are 626 satin chrome, 625 bright polished chrome, and 613E dark oxidized satin bronze equivalent. The escutcheon measures 2-3/16 inches wide by 8-21/32 inches long and 1/2 inch thick, with a 4-5/16 inch lever.
10) Is the ACSI 1520M a genuine Yale lock or an aftermarket unit?
It is a Yale 8800 Series mortise lock that ACSI modifies with its electrified 1500 Series motor-controlled hardware. So the mechanical case, trim designs and prep are Yale 8800, and the electric locking, request-to-exit and monitoring are ACSI's. Trim and prep match the rest of a Yale 8800 job.
11) Where is a motor controlled electric mortise lock the right choice instead of an electric strike or maglock?
Use this style where you need both locking and latching in the door itself, typically stairtowers and controlled areas. The lock latches mechanically every time the door closes, so the opening stays positively latched for fire rating purposes, and it is rated up to 3 hours UL/cUL. A maglock gives no latching and generally forces extra egress hardware; an electric strike puts the electronics in the frame instead, which is the easier retrofit when the door is already prepped for a mechanical mortise lock.
12) Is the ACSI 1500 Series mortise lock suitable for a high traffic commercial office entrance?
Yes, it is a commercial lock carrying ANSI/BHMA Grade 1 and it is listed for offices, shopping centers, industrial buildings and commercial facilities. The hub is 3/8 inch solid steel and the electrics are continuous duty rated, so it can sit energized all day.
