Sargent 8271 24V 26D RH – Frequently Asked Questions

1) Does the Sargent 8271 24V mortise lock unlock or lock when power is lost?
The 8271 is a fail safe lock body, which on this configuration means it is locked when energized. Drop the 24V DC power and the outside lever releases, so the opening is free. If your application needs the door to stay secure during a power failure, a fail safe device is the wrong choice and you want a fail secure (locked when power is off) version instead. Current draw is 0.25 amp continuous duty, so size the power supply for continuous, not intermittent, load.
2) What door thickness does the Sargent 8271 mortise lock body fit?
Standard 1-3/4 inch commercial doors. Thicker doors need a Sargent thick door kit; the lock body alone is set up for 1-3/4 inch as supplied. The mortise pocket is prepped for a 2-3/4 inch backset with a 3/4 inch throw latchbolt.
3) Is the Sargent 8271 a complete lockset or just the lock body?
Body only. You get the electrified 8200 Series mortise case with the stainless latchbolt; levers, roses or escutcheons, cylinder and strike are ordered separately. Budget for lever trim (the 8200 is a lever-handle lock) and a cylinder if the opening needs key override, since the body itself ships non-keyed.
4) Will the 8271 latch into the strike that is already in my frame?
If the existing opening is a standard ANSI mortise prep with a 2-3/4 inch backset, yes. The 8271 uses a 2-3/4 inch backset and a 3/4 inch latchbolt throw, which is the normal commercial mortise geometry. Where it differs from a mechanical 8200 swap is the wiring: you will need a door cord or electric hinge to get 24V power into the door edge, which a straight mechanical replacement did not require.
5) What is the difference between the Sargent 8271 and an electronic keypad mortise lock like the Alarm Lock Trilogy or TownSteel FME series?
Two different architectures. The 8271 is a dumb electrified lock body: it has no reader, no credentials and no onboard memory, and it takes its unlock signal from a separate access control panel over 24V DC. Standalone locks such as the Alarm Lock DL3500CR Trilogy or the TownSteel FME-2000 with RFID carry the reader and user database on the door itself and need no panel or wiring home run. Choose the 8271 when the building already has a head-end access control system and you want the door on it; choose a standalone when you just need coded or credentialed entry on one or two openings.
6) What other 24V electrified mortise lock bodies could I use instead of the Sargent 8271?
Two close alternatives in the same wired, panel-driven category: the BEST 45HW Series wired electromechanical mortise lock, which runs 12V or 24V, and the Command Access ML190 Series motorized mortise lock, a heavy-duty 24VDC storeroom-function unit whose EL/EU operation is field selectable. The Command Access field-selectable feature matters if you are not certain yet whether the opening needs fail safe or fail secure, since the 8271 24V is fixed fail safe. The Schlage L9092EU with 03A trim is another 12/24VDC electrified mortise option, and it includes request-to-exit switching.
7) My door is 1-5/8 inch thick. Does the Sargent 8271 24V fit, or is there a better choice?
The Sargent 8271 24V is designed for 1-3/4 inch doors, with specialized kits available for thicker doors. For a 1-5/8 inch door, the Alarm Lock Trilogy electronic mortise locks cover 1-5/8 to 1-7/8 inch: the DL2700CR is Grade 1 classroom function with weatherproof design, the DL3500CR is Grade 1 classroom with 300 user codes, and the DL4500 is a Grade 1 electronic mortise deadbolt. Note these are standalone keypad locks rather than 24V wired bodies.
8) What is the closest wired electrified mortise lock alternative to the Sargent 8271 24V?
The BEST 45HW is the nearest wired equivalent. It is a wired electromechanical mortise lock rated for 12V and 24V operation and is classed heavy duty, matching the Sargent 8271's 24V electromechanical lock function and heavy duty rating. The main difference is that the Sargent 8271 is supplied as a lock body only in the 8200 Series, so trim is specified separately, while the BEST 45HW comes from the 45HW Wired Mortise Series. Another wired option is the Command Access ML190, a motorized mortise lock with field selectable EL/EU operation at 24VDC in a storeroom function.
9) I need fail secure instead of fail safe on a 24V mortise opening. What should I use?
The Sargent 8271 24V is built for fail safe operation, meaning it is locked when energized, so it is not the part for a fail secure opening. The Command Access ML190 is a motorized mortise lock with field selectable EL/EU operation at 24VDC, letting the installer set electrically locked or electrically unlocked in the field. The Schlage L9092EU with 03A trim is an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation, and is a heavy duty corridor function.
10) Can I use a standalone keypad mortise lock instead of the Sargent 8271 24V?
Only if the opening does not have to answer to a central access control system. The Sargent 8271 24V is a wired electromechanical body that integrates with card readers and keypads through a 24V DC supply. Standalone alternatives carry their own credentials at the door: the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes in classroom function for 1-5/8 to 1-7/8 inch doors, the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock. These do not accept a remote unlock signal the way a wired 24V body does.
11) Which mortise locks look like substitutes for the Sargent 8271 24V but will not work on an access controlled opening?
Several mortise products share the word mortise without sharing the 24V electrified function of the Sargent 8271. The Schlage L0170 is a half dummy trim, non-keyed Grade 1 mortise lever lock with no latching function at all, and the Emtek 3019 Brisbane and 3102 Memphis mortise entrance locksets are also dummy function. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock. The Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and privacy keypad, which is a deadbolt rather than a latching lock body. The Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset at BHMA Grade 2 rather than Grade 1.
12) For a lockdown or intruder-function classroom, is the Sargent 8271 24V the right lock?
The Sargent 8271 24V is a fail safe electrified body, locked when energized, which means a power loss unlocks the opening - not the behavior most classroom lockdown specs call for. For intruder or classroom security duty, the BEST 45HCA heavy duty mortise lockbody is offered in an intruder function, the TownSteel FME-4000 is a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID for 1-3/4 inch doors, and the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors.
13) Do I have to specify handing when I order the Sargent 8271 electrified mortise lock?
No. The 8271 lock body is field reversible, so a locksmith can set it for any hand on site. That makes it practical to stock one part number for a building with mixed swings.
14) Is the Sargent 8271 heavy enough for a high traffic school or hospital corridor?
It is built for that. ANSI/BHMA Grade 1, heavy duty, with a heavy-gauge cold rolled steel case and zinc dichromate finish, and a two-piece anti-friction stainless latchbolt that holds up under constant use. Grade 1 is the top commercial durability tier and the one most institutional specs call for.
15) If I do not need the opening tied into an access control panel, what mortise lock replaces the Sargent 8271 24V?
The Sargent 8271 24V is an electromechanical 8200 Series body that requires a 24V DC supply and wiring to a controller. For a mechanical opening with no power run, the Accentra 8805FL is a Grade 1 storeroom mortise lock with Arcadia lever from the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. For classroom function, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors.
16) What are the wireless or credential-reader options if I want to avoid running wire to the door?
The Sargent 8271 24V needs a wired 24V DC feed to the lock body. If pulling wire is not practical, the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader, mobile enabled deadbolt with LED and Greenwich trim, right hand, with a 3 hour fire rating. The Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad for Adams Rite deadlatches. The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors.
17) Is a battery-powered or power-generating mortise lock an alternative to running 24V to the Sargent 8271?
The Sargent 8271 24V draws 0.25 amp continuous duty and depends on a 24V DC supply, so it needs a power run and a supply sized for continuous draw. The Dormakaba PowerPlex P2066 is a mortise lock in the PowerPlex 2000 Series, and the Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card back to back mortise lock, both of which put the credential and control at the door instead of at a panel. Choose these when the opening cannot be wired; choose the Sargent 8271 when the door must respond to a central system.
18) Can the Sargent 8271 24V be used on a behavioral health or ligature-resistant opening?
The Sargent 8271 24V is a standard commercial lever-trim mortise body and is not offered with anti-ligature trim. For those openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel with passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel.
19) What finish does the Sargent 8271 24V lock body come in?
It is offered in 26D, satin chromium plated over nickel, on the 24V version. Since this is the lock case rather than exposed trim, the visible finish on the door comes from the lever and rose or escutcheon you pair with it, so match those to the rest of the openings in the building.
20) Where do I find the door prep dimensions for a Sargent 8200 mortise lock?
Sargent publishes a 7800 and 8200 Series mortise lock installation template covering the sectional rose and escutcheon trims, and a full 7800/8200 mortise lock catalog. Both are attached to the 8271 and give the mortise pocket, cross-bore and trim hole locations you need before routing the door.
