Sargent 60-8270-24V-LNMD-26D – Frequently Asked Questions

1) What does fail-safe mean on the Sargent 60-8270 mortise lock, and what happens in a power failure?
Fail-safe means the outside lever unlocks when power is removed. On the Sargent 8200 Series 60-8270, the electromechanical function holds the outside lever locked while energized on 12 to 24VDC, so a power loss or a fire alarm release leaves the door free to enter from outside. If you need the opposite behavior, where the door stays locked when power drops, a fail-safe lock is the wrong choice and you want a fail-secure electrified function instead.
2) Does the Sargent 8200 electrified mortise lock come with a cylinder?
No core is supplied. The 60-8270 is prepped for a SARGENT large format interchangeable core and ships less core, so you order or supply the LFIC separately. Keying is specified at order: keyed different, keyed alike, to a key code, or none if you are supplying your own cylinder. It works with all SARGENT key systems, including Degree, Signature, KESO and XC.
3) What voltage power supply do I need for the Sargent 60-8270 mortise lock?
It runs on 12 to 24VDC, and the orderable configurations are built at 24V. EcoFlex energy management cuts draw on the electromechanical function by up to 96 percent, which matters when you are running several openings off one supply. Confirm your supply voltage and available current before you pull wire.
4) Is the Sargent 8200 mortise lock fire rated for a 3 hour opening?
Yes. The 8200 Series carries UL 10C fire rating up to 3 hours with NFPA 80 compliance, so it suits stairwell and cross-corridor openings in healthcare, education and government buildings.
5) Is this a standalone keypad lock or does it need an access control system?
It is a wired electrified mortise lock body, not a standalone credential lock. There is no keypad or card reader on board, so it needs an access control panel or power supply to switch it, plus a credential reader if you want card or keypad entry. If you want the reader built into the lock instead, look at a standalone unit such as the Alarm Lock DL3500CR Trilogy keypad mortise lock or the TownSteel FME-2000 with RFID.
6) Can I use the 8200 mortise lock on a door that has no power run to it?
No. The 60-8270 is an electromechanical function and needs 12 to 24VDC at the lock, which normally means an electric power transfer hinge or door loop. For an unpowered opening, use a mechanical Grade 1 mortise lock instead, such as the Corbin Russwin ML2003 classroom or the Cal-Royal NM8080 storeroom, both of which fit 1-3/4 inch doors.
7) What is the closest equivalent to the Sargent 60-8270 electromechanical mortise lock from another manufacturer?
The Sargent 60-8270 is a Grade 1 heavy duty electromechanical mortise lock running on 12 to 24VDC. The closest wired equivalents are the BEST 45HW Series wired electromechanical mortise lock, which is also heavy duty and operates on 12V/24V, and the Schlage L9092EU with 03A trim, a heavy duty mortise lock with keyed outside, request-to-exit switch and 12/24VDC operation. Command Access ML190 is a third route: a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC.
8) Is fail-safe the same as fail-secure when choosing between the Sargent 60-8270 and a Command Access ML190?
No. The Sargent 60-8270 is configured fail-safe, meaning the outside lever unlocks when power is removed, which is what a stair or egress-path opening on a fire alarm release typically calls for. The Command Access ML190 is field selectable between EL and EU operation, so one unit can be set either electrically locked or electrically unlocked at install. If the opening must stay secure on power loss, the fail-safe configuration is the wrong choice and a fail-secure selection is required.
9) Can a standalone keypad mortise lock be used instead of the wired Sargent 60-8270?
Only if the opening does not need to be released by the access control or fire alarm system. The Sargent 60-8270 is a wired 12 to 24VDC lock whose state is controlled by the panel. Standalone alternatives such as the BEST 45HZ EZ Series electronic keypad mortise lock with key override, the Schlage CO-100 standalone electronic mortise lock with keypad reader in privacy function, and the Alarm Lock DL3500CR Trilogy Grade 1 classroom lock with 300 user codes manage credentials at the door instead. They remove the wiring and power supply but also remove central remote unlock.
10) What should I use instead of the Sargent 60-8270 if the project wants wireless access control rather than hardwired?
Wireless mortise options include the Schlage Electronics LEMD-GRW, a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock with keypad for Adams Rite deadlatches, and the Dormakaba LX-I-M002 Saffire electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2. These avoid running power and control wire through the frame, while the Sargent 60-8270 needs a 12 to 24VDC feed to the door.
11) For a classroom or lockdown opening, is the Sargent 60-8270 the right lock or should I look at an intruder-function mortise lock?
The Sargent 60-8270 is fail-safe, so it unlocks on power loss and is not a lockdown lock on its own. For classroom security openings that must be secured from inside the room, look at the BEST 45HCA heavy duty mortise lockbody with intruder function, the Marks USA LA318GJ Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors, or the TownSteel FME-4000 Series Grade 1 electronic intruder classroom mortise lockset with RFID.
12) For a 3 hour fire rated opening, what alternatives to the Sargent 60-8270 carry a stated fire rating?
The Sargent 60-8270 is UL 10C fire rated up to 3 hours with NFPA 80 compliance. Among comparable electrified mortise locks, the Schlage Electronics LEMD-GRW ENGAGE Series wireless mortise lock carries a 3 hour fire rating at Grade 1, and the Schlage LEBMB-ADD mobile-enabled mortise lock carries a 3 hour fire rating at Grade 2. On the mechanical side the Falcon MA101 Grade 1 heavy duty mortise passage lock is fire rated. Always verify the rating against the door and frame label.
13) Do I have to specify handing for the Sargent 60-8270?
The lock body is field reversible, so handing is set during installation rather than being a separate part number. Trim orientation still needs to be confirmed on site before the door goes back on the hinges.
14) What lever and rose choices does the Sargent 60-8270 come in?
Two lever designs, MD and MI, both on the LN rose at 2 inches (51mm), in 26D satin chromium plated over nickel. If your building is already standardized on Sargent LN rose trim in 26D, the trim footprint will match the mechanical 8200 locks on the other doors.
15) Will this hold up on a high traffic entrance in a hospital or school?
It is built for that. The 8200 Series is Grade 1, heavy duty, and UL verified to 16 million cycles under Verification ID V584148, which is well beyond what a typical Grade 1 cycle test requires. Commercial rated, not residential.
16) Where do I get the door prep dimensions for a Sargent 8200 mortise lock?
Sargent publishes a dedicated installation template covering 7800 and 8200 Series mortise locks with all sectional rose and escutcheon trims, which gives the mortise pocket and trim hole layout for the LN rose used here. The 7800/8200 mortise lock catalog carries the full function and dimension tables.
17) If the opening does not need to be wired, what mechanical mortise lock replaces the Sargent 60-8270?
Where no access control tie-in is required, a mechanical Grade 1 mortise lock covers the same door prep class without power. Options include the Accentra 8805FL Grade 1 storeroom mortise lock, the Corbin Russwin ML2003 Grade 1 classroom mortise lockset for 1-3/4 inch doors, and the Cal-Royal NM8080 Grade 1 storeroom mortise lockset with an interchangeable core option. Pick the function code to match how the opening is used, since these are fixed-function mechanical locks rather than electrically controlled.
18) Will a mortise dummy or passage trim work as a substitute for the Sargent 60-8270 on a paired opening?
Only on the inactive or non-latching leaf. The Sargent 60-8270 is a keyed, single cylinder electromechanical lock that latches and is electrically controlled. A Schlage L0170 Grade 1 half dummy mortise trim and Emtek dummy mortise entrance locksets such as the 3104 Hamilton have no latch and no cylinder, and a Schlage PM010 Grade 1 passage latch mortise lock latches but never locks. None of these provide access control on a secured opening.
19) What is the difference between the Sargent 60-8270 and a behavioral health or anti-ligature mortise lockset?
The Sargent 60-8270 uses a standard MD or MI lever on an LN rose and is an electrically controlled, keyed lock. Behavioral health openings call for ligature resistant trim instead: the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in passage function, the MRX-A-01 uses ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage push/pull paddleset that is ligature resistant and ADA compliant. Those are passage devices, so they do not provide the keyed or electrified control the 60-8270 does.
20) Our facility standardizes on small format interchangeable core. How does the Sargent 60-8270 compare with cores on other mortise locks?
The Sargent 60-8270 is supplied prepped for a large format interchangeable core, less core, and works with SARGENT key systems including Degree, Signature, KESO and XC. If your standard is a different core family, the Cal-Royal NM8080 Grade 1 storeroom mortise lockset is offered with an interchangeable core option, and the BEST 45HZ EZ Series keypad mortise lock includes a key override cylinder. Confirm the core format against your existing masterkey system before ordering.
21) Can the function be changed later if the use of the door changes?
Yes. The 8200 Series is offered in 56 functions across electromechanical, security and monitoring options, and functions can be switched on site. For a property or facilities team standardizing across a building, that means one lock body family covers changing door uses without a full replacement.
22) Can I use a Codelocks CL2255 or a Kaba Ilco 185 in place of the Sargent 60-8270?
Neither is an equivalent. The Codelocks CL2255 is a medium duty electronic tubular mortise latch, below the heavy duty Grade 1 class the Sargent 60-8270 sits in, and the Kaba Ilco 185 Series is a deadbolt-function mortise lock with no lever operation. The Sargent 60-8270 is a keyed, lever-operated, heavy duty electromechanical mortise lock for high-traffic commercial openings.
