ACSI ACSI-M1520M-1-8205-26D – Frequently Asked Questions

1) What does fail secure mean on the ACSI M1520M-1-8205 mortise lock, and what happens if the building loses power?
The outside (secure side) trim is unlocked while power is applied and locked when power is removed, so on a power failure the lockset locks. The inside lever always retracts the latch for free egress, which is why these are used on stairtower and controlled-access doors. Control is motor driven rather than solenoid.
2) Which lock body does the ACSI M1520M-1-8205 modify, and will it drop into an existing Sargent 8200 mortise pocket?
It is a Sargent 8200 Series Office or Entry mortise lock body that ACSI electrifies for fail secure control. It uses the standard 8200 case, 2-3/4 inch backset and an 8 x 1-1/4 inch front, so it goes into the same mortise prep as the mechanical 8200 Office/Entry lock it replaces. The difference is the wiring run you now have to get into the door.
3) What door thickness and stile width does this ACSI 1500 Series electric mortise lock need?
It is built for 1-3/4 inch doors, the standard commercial thickness, and needs a minimum stile width of 4-3/4 inches. Narrow stile aluminum doors will not take it; that width rules out most storefront framing.
4) What voltage and current does the ACSI M1520M-1-8205 draw, and can I run it off my existing access control power supply?
It runs on 12 to 24VAC or VDC, drawing 250mA inrush and only 10mA holding, and it is continuous duty rated. That holding draw is low enough that several openings can share a modest filtered supply, but size the supply for the inrush of every lock that could energize at once.
5) Can this electric mortise lock be used on a labeled fire door?
Yes. The lock is UL and cUL Listed, California State Fire Marshal approved, and tested to ANSI/UL 10C positive pressure fire test of door assemblies, with fire doors named as an application. Because it is fail secure, the outside trim locks on power loss while the inside lever still allows egress, which is what a stairtower fire door assembly needs.
6) Will the latch on this ACSI lock throw into my existing Sargent strike?
The latchbolt is a one piece anti-friction reversible latch measuring 5/8 by 1 inch with a 3/4 inch throw, and it ships to work with a 4-7/8 by 1-1/4 inch curved lip strike with a 1-1/4 inch lip. If your frame already has ANSI 4-7/8 strike prep from a Sargent 8200, the latch lines up.
7) Do I have to order a separate handed lock, or is this one reversible?
The latch is a one piece anti-friction reversible type, so the lock body handles either hand without a separate part number. You do still have to specify finish, and you supply the trim and cylinder separately since this is a lock body.
8) Is this a Grade 1 lock, and is it rated for high traffic openings?
It meets ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and Security Grade 1 with all standard trims, which is the top commercial mortise rating and the usual spec for schools, hospitals and multi-family corridors. The hub is cold forged steel.
9) Can I monitor whether the door is latched with this lock?
Yes, latchbolt monitoring is an available electric option on this 1500 Series lock body, so the access control head end can see latch status rather than just door position. Motor controlled versions also offer user selectable fail safe or fail secure operation in the field.
10) What finishes can I get the ACSI M1520M-1-8205 mortise lock body in?
Five finishes: 10A satin bronze blackened, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome, and 605 bright brass. For matching a floor of existing openings, 626 satin chrome is the common commercial default.
