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

1) Will the ACSI M1510M-1 electrified mortise lock unlock automatically if the building loses power?
Yes. The 1510M fail safe function locks the outside trim while power is applied and releases it when power is removed, so a power failure leaves the lock in passage and the door free from both sides. Energized, it behaves as a storeroom function. On motor-controlled 1500 Series locks the fail safe/fail secure choice is field selectable, so the same lock can be set the other way if the opening needs to stay locked on power loss. Confirm which behavior your local life safety code requires for the opening before you set it.
2) Does the ACSI M1510M-1-ML2055-LC come with a cylinder?
No. LC means less cylinder, so you supply the mortise cylinder and keying yourself. That is the usual choice when a facility is keyed into an existing master system or a restricted keyway, since you can drop in your own cylinder rather than rekey a supplied one. Budget for a mortise cylinder with the correct length for a 1-3/4 inch door and the cam the Corbin Russwin 2000 Series mortise case takes.
3) Will this ACSI mortise lock latch into a strike that is already in my frame?
It ships to an ANSI straight lip strike measuring 4-7/8 by 1-1/4 inches with a 1-1/8 inch lip. The main latchbolt is 5/8 by 1 inch with a 3/4 inch throw, and there is a separate auxiliary deadlatch throwing 9/16 inch. If your frame already has a standard ANSI 4-7/8 inch strike prep, it drops in. If the existing strike is a T-strike or a non-ANSI box, the frame needs to be reworked. Lip length matters too: 1-1/8 inch suits a flush frame, and a deeper stop or applied trim wants a longer lip.
4) What voltage and current does the ACSI 1500 Series electric mortise lock draw, and can I run it off my existing access control power supply?
It runs on 12 to 24 VAC or VDC, drawing 250mA inrush and only 10mA holding. That holding draw is low enough that a modest access control supply carries several openings, but size the supply for the inrush of every lock that could energize at once. It is continuous duty rated, so it can sit energized indefinitely, and it is built to interface with life safety systems for fire alarm release.
5) Is this ACSI electrified mortise lock rated for a stairwell door or a fire rated opening?
The 1500 Series electric mortise locks are made for stairtower doors and controlled areas where the opening has to both lock and latch, and they are UL Listed and California State Fire Marshal approved. The lock meets ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, and it is ADA compliant to the A117.1 accessibility code, which matters because a stair door on an egress path needs lever operation that meets accessibility requirements. Set fail safe so the outside trim releases on alarm if your code requires stair re-entry.
6) Do I have to order the ACSI 1510M mortise lock handed?
No. Handing is field reversible on this lock, so one part number covers left and right hand doors and you can stock a single spare for a whole building. That is the practical difference from a handed mortise case, which has to be specified correctly at order or returned.
7) Can I monitor whether the door is latched with this ACSI mortise lock?
Latchbolt monitoring is the electrical option on this lock, so the access control panel can see whether the latchbolt is actually thrown rather than only whether the lock is powered. That is the difference between knowing a stair door is secure and assuming it is. Pull the monitor conductors back to the panel as a separate input when you spec the door cord and hinge transfer.
8) What lever and rose designs and finishes can I get on the ACSI 1500 Series Corbin Russwin 2000 mortise lock?
Trim comes in four Corbin Russwin lever designs, LW, NS, PS and RW, paired with A, M or N rose designs (N rose is offered with the LW lever). Finishes are 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright polished chrome, 626 satin chrome and 630 satin stainless. Lever is 5-1/8 inches and the rose measures 2-1/4 by 2-1/4 inches, so it covers a comparable footprint if you are matching the other openings in the building. For a school or hospital corridor, 630 satin stainless is the usual match to existing Corbin Russwin trim.
9) How far apart are the lever and cylinder holes for prepping the door face?
Spacing is 3-5/8 inches from the knob or lever centerline to the cylinder, and 2-7/16 inches from the knob or lever to the thumbturn. Those are the numbers you cut the door face to when you are drilling for the trim and the cylinder on a 1-3/4 inch door, alongside the 8 x 1-1/4 x 3/32 inch front on the edge.
10) Is the latch on this ACSI mortise lock suitable for a high traffic door with a closer?
The latchbolt is a two-piece mechanical design with an anti-friction insert, which reduces the drag that shows up on doors under closer pressure or positive stack pressure in a stairwell. Hub is 5/16 inch steel and the front is heavy gauge steel. The lock carries ANSI/BHMA Grade 1 for operational and security, the level specified for offices, schools, hospitals and hotels.
