ACSI ACSI-M1520M-1-8808FL-630 – Frequently Asked Questions

1) What happens to the ACSI M1520M-1-8808FL mortise lock when power is lost?
Set as fail secure, the outside lever stays locked when power drops. Power applied unlocks the outside trim; remove power and it locks again. Because it is a motor-controlled lock, the fail safe / fail secure mode is user selectable in the field, so the same lock body can be flipped to unlock on power loss if the opening calls for that. The inside lever always retracts the latch for free egress.
2) Will this ACSI electrified Yale 8800 mortise lock fit my door and existing mortise pocket?
It is built for 1-3/4 inch doors with a 2-3/4 inch backset, which is the standard commercial mortise prep. The case measures 4-1/8 x 1 x 6-1/16 inches and the front is 8 x 1-1/4 inches. Hub is 3/8 inch solid steel. If your opening is already prepped for a Yale 8800 mortise lock at 2-3/4 backset, the pocket and front cutout line up; you will need to run wire to the lock through a door cord or electric hinge, which a plain mechanical prep won't have.
3) Do I have to order a handed lock, or can it be reversed on site?
Handing is not an ordering decision here. The 1520M lock body is reversible in the field, so one part number covers left and right hand openings. For a property manager stocking spares across a building, that means a single lock on the shelf can cover any door in the group.
4) What voltage and current does the ACSI 1520M motor-controlled mortise lock draw?
It runs on 12 to 24V, AC or DC, drawing 250mA inrush and only 10mA holding. The low holding current means several of these can sit on a modest access control power supply without upsizing it, and the lock is continuous duty rated so it can stay energized indefinitely.
5) Can this lock be used on a fire rated stairwell or corridor door?
Yes. The 1500 Series electric mortise lock is UL Listed, California State Fire Marshal approved, and UL/cUL fire rated up to 3 hours. It meets ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and A156.115, and it is ADA compliant. ACSI built the series specifically for stairtower doors and controlled areas where the opening has to both lock and latch while still meeting life safety code.
6) Does this ACSI mortise lock give an access control panel any status feedback?
It includes a latchbolt monitor, so the panel sees whether the latch is actually projected, and the lock is set up for request to exit signaling from the inside lever. That combination is what lets you alarm a forced or propped stairtower door and shunt the alarm on legitimate egress.
7) Will the 3/4 inch latch throw work with the strike already in my frame?
The latchbolt throws 3/4 inch and ships with a curved lip strike measuring 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip. That is the standard ANSI mortise strike footprint, so an existing frame cut for a Yale 8800 mortise strike takes it directly. If your frame has a flat lip or a different lip length, use the supplied strike or match lip length to your jamb return so the latch lands cleanly.
8) What cylinder does this take, and how is it keyed when it ships?
It accepts a 6-pin mortise cylinder and comes keyed random. If you are standardizing a building on one master system, plan to swap in your own keyway cylinder or order keying to your system, because keyed random means no two locks will match.
9) Should I use a motor-controlled electric mortise lock or a solenoid one?
ACSI's 1500 Series comes both ways. The motor-controlled version, which this is, lets you select fail safe or fail secure in the field and draws very little holding current, so it suits a stairtower or controlled opening where the code requirement may change or where you are powering a run of locks off one supply. A solenoid-controlled lock is fixed to the operation it was built for and holds continuously energized. If you already know the opening is permanently fail secure and you do not need to change it later, solenoid is the simpler order; if you want one part that covers both, take the motor version.
10) Which finishes does the ACSI M1520M-1-8808FL come in?
Seven: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 613E dark oxidized satin bronze, 629 bright stainless, and 630 satin stainless. For matching existing openings in a commercial building, 630 satin stainless is the usual standard; 605 and 606 are the brass options when the rest of the hardware is brass.
11) Is this lock appropriate for classroom and office doors, or is it only for stairwells?
The listed applications are classroom, office, and utility room doors, as well as the stairtower use the 1500 Series was designed around. The underlying body is a Yale 8800 classroom mortise lock modified for electric fail secure control, so mechanically it behaves like the classroom function hardware already hanging on those doors, with remote lock and unlock added.
