ACSI ACSI-M1510M-1-ML2055-ESA-626-LC – Frequently Asked Questions

1) What happens to the ACSI M1510M-1-ML2055-R mortise lock when the power goes out?
It unlocks. The M1510M-1 is a fail safe (power lock) configuration: outside trim is locked while power is applied and releases the moment power is removed, so on a power failure the opening reverts to passage function. Energized, it behaves as a storeroom function lock, meaning the outside lever is locked and the inside lever always retracts the latch for free egress. That is the behavior you want on a stairtower or controlled-area door tied into a fire alarm or life safety system.
2) Can this ACSI 1500 Series motor-controlled mortise lock be switched to fail secure in the field?
Yes. Fail safe versus fail secure is field selectable on the motor-controlled 1500 Series locks, so the same lockset can be set to release on power loss or to stay locked on power loss without ordering a different part number. That matters if you are standardizing across a building where stair doors need fail safe and a storage or IT room on the same access control panel needs fail secure.
3) What voltage and current draw should I size the power supply for on the ACSI 1500 Series mortise lock?
It runs on 12 to 24VAC or VDC, drawing 250mA inrush and 10mA holding. Because it is a motor-controlled lock it is continuous duty rated with low holding current, so a modest access control power supply carries several openings. Size the supply for the inrush of however many locks can be released at once, not the holding figure.
4) Is this ACSI electric mortise lock Grade 1 and code approved for a hospital or school corridor?
It carries ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, is UL Listed, California State Fire Marshal approved, and meets the A117.1 accessibility code. The lever trim is ADA compliant. ACSI lists offices, schools, hospitals and hotels as intended applications.
5) Will this lock latch into my existing ANSI strike, or do I need to change the frame prep?
The latch throws 3/4 inch into a 4-7/8 x 1-1/4 inch ANSI straight lip strike with a 1-1/8 inch lip, which is the standard commercial frame prep. The auxiliary deadlatch throws 9/16 inch and the latchbolt itself is 5/8 x 1 inch, two-piece mechanical with an anti-friction insert so it does not drag on a door under closer pressure or positive pressure. If your frame is already cut for a 4-7/8 ANSI strike, the frame side needs no work.
6) Do I have to specify handing when ordering this ACSI mortise lever lock?
No. The lock is field reversible, so one part number covers left and right hand openings and you set the hand during installation. For a property manager or integrator stocking spares, that means a single lock on the shelf covers any door in the building.
7) What is the Authorized Egress (AE) option on the ACSI M1510M mortise lock?
AE is an ordering option on this lockset, offered alongside the base configuration with either the A rose or M rose ES lever design. The AE builds carry the same ES lever trim and less-cylinder arrangement in satin chrome. Decide between the plain M1510M-1 and the M1510M-AE-1 at order time, since it is part of the model number rather than a field change.
8) What lever and rose choices are there, and what finish does it come in?
Trim is the ES lever design with a choice of A rose or M rose, both on a 2-1/4 inch square rose footprint, in satin chrome (626). The lever measures 4-5/8 inches and the lock projects 2-3/8 inches off the door face. The A and M rose are purely a trim appearance choice, so pick whichever matches the other openings in the building.
9) Can I monitor whether the door is latched with this ACSI lock?
Yes, the lock is configured with a latchbolt monitor, so it reports latch status back to your access control panel or head end. That lets a security integrator confirm a stair or controlled-area door actually relatched after a release rather than relying on a door position switch alone.
10) Should I use an electrified mortise lock like this or an electric strike for a stairwell door?
An electrified mortise lock controls the trim at the door, so the latch stays projected at all times and the door remains latched and positively secured even while unlocked for entry. ACSI built the 1500 Series specifically for stairtower doors and controlled areas where both locking and latching are required. An electric strike releases the latch instead, which is fine for a general access door but is the wrong approach where the latch must stay engaged. The tradeoff is that this lock needs power transferred through the door, where a strike is wired in the frame.
