ACSI ACSI-M1520M-1-ML2055-DSA-625-RH-LC – Frequently Asked Questions

1) What happens to this ACSI fail secure mortise lock when the power drops?
Outside trim locks. Power applied unlocks the outside (secure side) lever; remove power and the lockset locks, so a power failure leaves the door secured. The inside lever always retracts the latch for free egress, which is why it suits stairtowers and controlled areas. On the motor controlled version fail safe versus fail secure is field selectable, so you can flip it to unlock on power loss if your life safety plan calls for that.
2) What voltage and current does the ACSI 1500 Series motor controlled mortise lock draw?
It runs on 12 to 24V, AC or DC, drawing 250mA inrush and 10mA holding. That holding current is low enough that several locks can sit on a modest access control power supply. The lock is continuous duty rated, so it can stay energized indefinitely.
3) Do I have to specify handing on the ACSI M1520M-1-ML2055 mortise lock?
Yes, it is a handed lock and cannot be field reversed. Order left hand or right hand to match the door. Both hands are offered in 625 bright chrome and 626 satin chrome, so a building standardizing on one finish can cover openings swinging either way.
4) Does this ACSI electric mortise lock come with a cylinder?
No. It ships less cylinder, so you supply a mortise cylinder in your building's keyway along with the cam your locksmith specifies. Spacing is 3-5/8 inches lever to cylinder and 2-7/16 inches lever to thumbturn. Trim uses a 2-1/4 by 2-1/4 inch rose with a 4-1/2 inch lever and a 5/16 inch steel hub.
5) Will this ACSI mortise lock latch into my existing Corbin Russwin strike?
The lock ships with a straight lip strike, 4-7/8 by 1-1/4 inches with a 1-1/8 inch lip. Latchbolt is a 2-piece mechanical type with anti-friction insert, 5/8 by 1 inch face, throwing 3/4 inch, with a 9/16 inch auxiliary deadlatch. If your frame already carries a 4-7/8 by 1-1/4 ANSI strike prep, it drops in; a curved or extended lip strike would need to be swapped or the lip length matched to your jamb reveal.
6) Is this ACSI electrified mortise lock Grade 1 and code approved 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 A117.1 accessibility code. ADA compliant with the lever trim. Stated applications are offices, schools, hospitals and hotels, which is what an institutional standard normally requires on a stair or controlled-access opening.
7) Can I monitor whether the door is latched with this lock?
Yes, the M1520M-1-ML2055 is built with a latchbolt monitor, so the access control panel or head end can see whether the latch is actually projected rather than just whether the lock is powered. That is the signal you want on a stairtower or secure room where a door pushed to but not latched has to raise an alarm.
8) What is the difference between the motor controlled and solenoid controlled ACSI 1500 Series mortise locks?
Both allow remote electric locking or unlocking while meeting life safety codes. The motor controlled version, which this one is, adds user selectable fail safe or fail secure operation in the field and draws very little power, so one lock can be configured either way after it is installed. A solenoid controlled lock is fixed to the function it was built as.
9) What finishes does the ACSI M1520M-1-ML2055 mortise lever lock come in?
Two: 625 bright chrome and 626 satin chrome. 626 is the usual commercial standard and the easier match to existing levers, closers and exit devices in most office and institutional buildings; 625 is the polished version for openings where brighter trim is the building standard. Each is available left hand and right hand.
