ACSI M1510M-1-ML2055-LL-626 – Frequently Asked Questions

1) What happens to the ACSI M1510M-1-ML2055-LL lock when power is lost?
It unlocks. The M1510M-1-ML2055-LL is a fail safe (power lock) configuration, so the outside lockset is released when power drops. That is what you want on a stairtower or controlled-egress opening where people have to get back into the floor during an alarm or outage. If you need the door to stay secure without power, fail safe is the wrong choice and you need a fail secure lock body instead.
2) Will this ACSI electrified mortise lock work with Corbin Russwin 2000 Series hardware?
Yes. The M1510M-1-ML2055-LL is a Corbin Russwin 2000 Series mortise lock body that ACSI modifies for electrified fail safe operation, and it is built specifically for the Corbin Russwin 2000 Series. It carries the L rose and L lever design, so it matches openings already trimmed with Corbin Russwin L design levers.
3) Is this ACSI fail safe mortise lock listed for use on a fire rated stair door?
The lock is UL Listed and California State Fire Marshal approved, and it is also continuous duty rated. Locking and latching are both provided, which is what stair reentry openings require. Confirm the specific opening's fire assembly requirements with your AHJ, since a fail safe lock releases the outside trim on power loss by design.
4) Should I order the motor controlled or the solenoid controlled ACSI 1500 Series lock?
ACSI builds the 1500 Series electric mortise locks both ways. The M1510M-1-ML2055-LL is the motor controlled version, which draws low power and suits circuits that stay energized around the clock. Solenoid versions switch faster and are simpler electrically, but draw more current when held. Either one gives you remote electric locking or unlocking while conforming to life safety codes.
5) Is the ACSI ML2055-LL a complete lockset or just the electrified lock body?
It is supplied as a lock part or component, a Corbin Russwin 2000 Series mortise lock body that has been modified for fail safe motor control, with L rose and L lever trim called out. It is a commercial-grade item. Plan on a low voltage power supply and, if you are switching it remotely, the access control or relay device to drive it, since those are separate items.
6) Can I keep a key override on an electrified ACSI fail safe mortise lock?
The ML2055 function is the office/entry arrangement on the Corbin Russwin 2000 Series body, modified so that standard control locks the outside (secure side) trim. Cylinder-prepped variants are offered, along with less cylinder (LC) versions for keying supplied separately in the field. Order the LC configuration if your locksmith is fitting your own keyway.
7) What finishes can I get on the ACSI M1510M-1-ML2055-LL to match the rest of my building's doors?
Seven finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright polished chrome, 626 satin chrome, and 630 satin stainless. For commercial corridors and stair doors, 626 and 630 are the usual standardization picks across a facility.
