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

1) Does the ACSI M1520M fail secure mortise lock really lock on power loss, or does it unlock?
Read the function carefully, because the naming trips people up. With the 1520M fail secure control, outside trim is LOCKED when power is applied (storeroom function while energized) and UNLOCKS when power is removed, giving passage function on a power failure. So on a power drop, the outside lever gets you in. If you need the opposite behavior, the motor-controlled lock has simple user selectable fail safe / fail secure operation, so the mode is field selectable on the lock itself.
2) Will the ACSI 1500 Series electric mortise lock fit my door, and do I have to order it handed?
It's built for a 1-3/4 inch door with a 2-3/4 inch backset, the standard commercial mortise prep. Handing is field reversible, so one lock covers left or right hand openings without a separate part number. Case body is 4-1/8 x 1 x 6-1/16 inches with an 8 x 1-1/4 inch front, and the trim projects 3 inches off the face.
3) The M1520M-8808-LC comes less cylinder - what else do I need to order to finish the job?
You supply the mortise cylinder. LC means less cylinder, so the lock ships without one and you key it into whatever keyway and keying system the rest of the building runs, which is usually why a facility orders it this way. You also need a low voltage supply: 12 to 24VAC/VDC, 250mA inrush, 10mA holding. Strike is included in the spec as a curved lip type, 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip.
4) Is this ACSI mortise lock approved for a fire rated stair door?
The 1500 Series electric mortise lock is UL/cUL fire rated up to 3 hours, UL Listed, California State Fire Marshal approved, and meets ANSI/BHMA A156.13 Series 1000 Operational Grade 1 plus A156.115. It's also listed as ADA compliant. That combination is what lets it go on stairtower doors and controlled areas where both locking and latching are required while still conforming to life safety codes.
5) Will this ACSI lock latch into the strike already in my frame?
Latch throw is 3/4 inch with a stainless steel one-piece anti-friction latchbolt, and the supplied strike is a curved lip unit, 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip. That is the common ANSI mortise strike size, so if your frame is prepped for a standard mortise lock it should drop in. Anti-friction latch matters on doors with a closer, it keeps the latch from dragging the strike lip.
6) What power supply do I need for the ACSI 1500 Series motor controlled mortise lock?
Run it on 12 to 24VAC or VDC. Draw is 250mA inrush and 10mA holding, and the lock is continuous duty rated, so a modest access control power supply handles several openings. Low holding current is the practical advantage of the motor-controlled version over a solenoid lock on a long run of doors.
7) Can I monitor the door status from this lock, and what can the switch carry?
It comes configured with a latchbolt monitor, so your access control panel can see whether the latch is actually thrown rather than just whether the door contact closed. Switch rating is 2A at 30VDC or 3A at 125VAC. Request to exit is available as an option if you also need egress signaling to shunt an alarm.
8) Which lever and escutcheon designs can I get on the ACSI M1520M-8808 Yale 8800 mortise lock?
Four Yale lever designs: MO (Monroe), PB (Pacific Beach), PN (Pinehurst) and VI (Virginia). Each pairs with either the CN (Camden) or R (Copenhagen) escutcheon. Escutcheon trim measures 2-3/16 inches wide, 8-21/32 inches long and 1/2 inch thick, with a 4-5/16 inch lever. If you're matching existing Yale 8800 openings in the building, pick the lever and escutcheon already on those doors.
9) Motor controlled or solenoid controlled electric mortise lock - which should I spec?
ACSI's 1500 Series is offered both ways. The motor controlled version, which is what the M1520M is, gives you simple user selectable fail safe or fail secure operation at the lock rather than a fixed factory setting, and it draws only 10mA holding. Solenoid control is the choice when you want a straightforward continuous-power release and don't need to flip the failure mode in the field. Either way the lock both locks and latches, which is what stairtower and controlled-area openings require.
10) Is this ACSI electrified mortise lock heavy duty enough for a commercial office or shopping center entry?
It's a commercial-grade lockset, ANSI/BHMA Grade 1 under A156.13 Series 1000, with a solid steel 3/8 inch hub and a stainless steel latchbolt. ACSI lists it for offices, shopping centers, industrial buildings and commercial facilities. Grade 1 is the highest ANSI durability tier for locksets and is what most institutional and multi-family specs call for on traffic doors.
11) What finishes does the ACSI 1500 Series Yale 8800 electrified mortise lock come in?
Three: 626 satin chrome, 625 bright polished chrome, and 613E dark oxidized satin bronze equivalent. All three are offered across every lever and escutcheon design combination, so the finish choice doesn't limit which trim you can pick.
