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

1) Will the ACSI 1500 Series electrified mortise lock fit my door, and what backset does it need?
The 1500 Series electric mortise lock is prepped for a 1-3/4 inch door with a 2-3/4 inch backset, which is the standard commercial mortise prep. 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, so it drops into a standard ANSI mortise pocket cut for those dimensions. Projection off the door face is 2-9/16 inches.
2) Is this ACSI electrified mortise lock handed, and which hand do I order?
Handing matters here. The lock is handed, and it is ordered as either left hand or right hand, in 625 bright chrome or 626 satin chrome. Determine the hand from the outside (secure side) of the opening before you order, because a handed mortise case is not something you flip in the field.
3) Can I set this ACSI motor-controlled mortise lock to fail safe or fail secure in the field?
Yes. Fail safe versus fail secure is user selectable on the motor-controlled 1500 Series locks, so one part number covers both behaviors. Fail safe releases the outside trim when power drops (passage), fail secure keeps the outside trim locked on power loss. Set it to suit the code requirement for the opening, which on a stair tower usually means egress side always free and the outside behavior dictated by the local authority.
4) 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 low holding current lets you run several openings off a modest supply, and it is continuous duty rated so it can sit energized indefinitely. Size the power supply off the inrush figure, not the holding figure, especially if multiple locks can be released at once.
5) Does this ACSI mortise lock report door status back to the access control panel?
It carries a latchbolt monitor and a request-to-exit (authorized egress) output, so the panel can see when the latch is secure and when someone has operated the inside lever to leave. That is what lets you shunt an alarm on a legitimate exit rather than treating it as a forced door.
6) Will this lock latch into the strike already in my frame?
The lock ships with an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with a 1-1/8 inch lip. Latchbolt throw is 3/4 inch with a 5/8 x 1 inch two-piece mechanical latchbolt and anti-friction insert, and the auxiliary deadlatch throws 9/16 inch. If your frame is already cut for a standard ANSI 4-7/8 inch strike, it drops in; a T-strike or a non-ANSI frame prep will need modification.
7) Does a cylinder come with the ACSI M1520M-AE-1-ML2055 mortise lock?
No. It is supplied less cylinder, so you order the mortise cylinder separately and key it into your existing system. That is usually what a facility wants, since it lets the lock match the keyway already running on the rest of the building. Cylinder spacing is 3-5/8 inches from lever to cylinder, and 2-7/16 inches from lever to thumbturn.
8) Does this electrified 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 and California State Fire Marshal approved, and it meets A117.1 accessibility with a 4-1/2 inch lever. Typical applications are offices, schools, hospitals and hotels, and the stated ADA compliance plus Grade 1 rating is what most institutional specs call for on a stair tower or controlled-area door.
9) What is the difference between the motor-controlled and solenoid-controlled ACSI 1500 Series mortise locks?
Both allow remote electric locking and unlocking on stair tower and controlled-area doors where the opening has to latch as well as lock. The motor-controlled version, which this one is, adds user-selectable fail safe/fail secure operation and low power draw, so you can change the power-off behavior without swapping hardware. Choose solenoid control only if the spec calls it out specifically.
10) What finishes does the ACSI 1500 Series Corbin Russwin mortise lock come in?
Two chrome finishes: 625 bright chrome and 626 satin chrome, each in left or right hand. If you are standardizing a corridor, 626 satin chrome is the one that matches most existing commercial lever trim, while 625 is the polished look.
11) What size hub and lever does this mortise lock use?
The hub is 5/16 inch and made of steel, with a 4-1/2 inch lever and a 2-1/4 by 2-1/4 inch rose. The front is heavy gauge steel. Those are the numbers to check against any trim you plan to carry over from an existing Corbin Russwin 2000 Series opening.
