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

1) What happens to the ACSI M1510M-1-ML2055-H lock if the building loses power?
Power failure unlocks the outside lever. The M1510M-1-ML2055-H is wired fail safe: outside trim is locked while power is applied (storeroom function when energized) and unlocks the moment power is removed, leaving the door in passage function. That is the behavior stairtower and egress-path openings usually need, and it is why the lock is built to interface with life safety systems. If your opening needs to stay locked during a power loss instead, the motor-controlled lock is user selectable between fail safe and fail secure in the field.
2) Do I have to order the ACSI 1500 Series mortise lock handed, and can I flip it on the job?
Handing is ordered, not field-changed. The M1510M-1-ML2055-H is a handed lock and is sold as left hand or right hand, each in 625 bright chrome or 626 satin chrome. Determine the hand at the door before you order: stand outside the opening (the secure side), and if the hinges are on your right it is a right hand door.
3) Can I reuse the existing strike when I swap in this ACSI Corbin Russwin 2000 Series electric mortise lock?
Check the strike against these numbers. The lock uses an ANSI straight lip strike, 4-7/8 by 1-1/4 inches with a 1-1/8 inch lip, a 3/4 inch latch throw, and a 5/8 by 1 inch latchbolt with a 9/16 inch auxiliary deadlatch throw. If the frame already carries an ANSI straight lip strike prep at 4-7/8 x 1-1/4, the latch drops in. A curved lip or a T-strike prep will not accept it, and if your frame gap is deeper than the 3/4 inch throw you need a strike with a longer lip, not a different lock.
4) What voltage and current does the ACSI 1500 Series motor controlled mortise lock draw?
It runs on 12 to 24 volts, AC or DC, drawing 250mA inrush and 10mA holding. That 10mA hold is low enough that several openings can share a modest supply, and the lock is continuous duty rated so it can sit energized indefinitely without a duty cycle limit. Size the power supply for the inrush of every lock that could actuate at once, not the holding figure.
5) Does this ACSI mortise lock come with a cylinder, and what else do I need to order?
It ships less cylinder. The M1510M-1-ML2055-H is supplied without a cylinder so you can key it into whatever system the building already runs, so add a mortise cylinder to the order along with your lever and rose trim. Cylinder spacing on the case is 3-5/8 inches from lever to cylinder and 2-7/16 inches from lever to thumbturn. The lock also carries a latchbolt monitor, so a monitored opening needs the low-voltage run back to the panel pulled at rough-in.
6) Does the ACSI M1510M electric mortise lock meet Grade 1 and ADA requirements for a school or hospital?
It is ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, UL Listed, California State Fire Marshal approved, and meets the A117.1 accessibility code, with ADA compliant lever trim. That combination is what institutional specs for offices, schools, hospitals and hotels usually call out, and the 4-1/2 inch lever gives the no-tight-grasping operation A117.1 requires.
7) What is the latchbolt monitor on this ACSI lock actually for?
The latchbolt monitor is a switch that reports whether the latch is projected, so the access control panel or head end knows the door has actually latched rather than just closed. On a stairtower or a controlled area that matters: a door pulled to but not latched reads as secure without it. Wire the monitor leads back to your panel input when you rough in the 12 to 24 volt power for the lock.
8) Is the ACSI M1510M-1-ML2055-H tough enough for a high traffic stairtower door?
Built for it. The lock uses a heavy gauge steel front, a steel hub at 5/16 inch, and a two-piece mechanical latchbolt with an anti-friction insert, which is what keeps the latch retracting cleanly on a door under closer or stack pressure. It is rated Operational and Security Grade 1 under ANSI/BHMA A156.13 and continuous duty rated on the electrical side, so it can stay energized around the clock.
9) How far does this ACSI mortise lever lock stick out from the door face, and how big is the rose?
Projection is 2-9/16 inches from the door face, with a 2-1/4 by 2-1/4 inch rose. Worth checking on a door that swings into a tight return wall or where a pair of leaves nest close, and worth confirming against the existing rose footprint if you are covering up an old prep, since a 2-1/4 inch rose will not hide a larger escutcheon cutout.
10) Will this match the chrome hardware already on my other doors?
Two chrome finishes are offered: 625 bright chrome (polished) and 626 satin chrome (brushed), each available left hand or right hand. 626 satin chrome is the common institutional standard, so if the rest of the building is brushed chrome that is the one to match. Hold a lever from an existing door beside the finish code on the old hardware before you commit a fleet order.
