Sargent 8270 EA BSP – Frequently Asked Questions

1) What voltage does the Sargent 8270 electrified mortise lock run on?
12 to 24VDC, and voltage is a selection you make when ordering: 12V or 24V. EcoFlex power management cuts current draw on the electromechanical function by up to 96 percent, which matters when you are sizing a power supply across a run of doors or pushing power a long way down a hinge transfer. Confirm your supply's voltage and current capacity against the lock before you wire it.
2) Can the Sargent 8270 be used on a fire rated door?
Yes. The 8270 is UL 10C fire rated up to 3 hours and compliant with NFPA 80, which covers most rated openings in commercial corridors, stairwells and cross-corridor pairs. It is a Grade 1, heavy duty lock, and the UL Cycle Above and Beyond test was completed at 16 million cycles (Verification ID V584148), so it holds up on the highest-traffic doors in a building.
3) Do I have to order the Sargent 8270 mortise lock handed?
No. Handing on the 8270 is field reversible, so one lock covers left and right hand openings and you can stock a single part number across a building instead of splitting your shelf between hands. Sort the hand at the door during install.
4) Will the Sargent 8270 work with my existing Sargent keyway and master key system?
It integrates with all SARGENT key systems, including Degree, Signature, KESO and XC, so the 8270 drops into an existing Sargent masterkey hierarchy rather than starting a second system. It is a single cylinder, keyed lock. On the order you pick the cylinder arrangement: standard cylinder, less cylinder, 70 for small format interchangeable core prep less core, or 60 for large format interchangeable core prep less core. If your facility already runs SFIC, take the 70 prep and stuff your own cores so keying stays in house.
5) What do I need to specify when ordering a Sargent 8270 mortise lock?
Five things. Voltage (12V or 24V). Cylinder arrangement (standard cylinder, less cylinder, or 70 SFIC prep / 60 LFIC prep less core). Keying (keyed different, keyed alike, or to a key code, and none if you took less cylinder, plus the key code itself if you are matching an existing system). Lever style, from A, B, E, F, J, L, P and W. And rose: E at 3-1/16 inches (78mm), L at 3-1/2 inches (89mm), LN at 2 inches (51mm), or O at 2-3/4 inches (67mm). Then the finish.
6) Will the Sargent 8270 work with a low energy door operator?
It is compatible with all low energy operators except the 5800. So on an ADA push-button opening where an operator swings the door, the 8270 handles the electric release side of the sequence, but if the opening already has a 5800 operator on it, pair the operator with a different electrified lock.
7) What is the difference between the Sargent 8270 fail-safe and an electrified mortise lock that can be set fail-secure?
The Sargent 8270 is built as a fail-safe electromechanical mortise lock, meaning its operating mode is fixed by the model rather than chosen in the field. The Command Access ML190 Series is a motorized mortise lock with field selectable EL/EU operation and 24VDC power in a heavy-duty storeroom function, so one lock body can be set either way on site. The Schlage 03A is an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC in a heavy duty corridor function. The Sargent 8270 accepts either 12V or 24V, while the Command Access ML190 is specified at 24VDC. Confirm which state the door must take on power loss against the life safety and egress requirements for the opening before selecting.
8) What is the closest wired electric mortise lock to the Sargent 8270 if I need a different manufacturer?
The BEST 45HW is the nearest wired electromechanical mortise lock in the comparable range - it is a heavy duty wired mortise lock with 12V/24V operation, the same dual-voltage window the Sargent 8270 runs on. The Sargent 8270 is a Grade 1 heavy duty mortise lock with an electromechanical lock function, keyed single cylinder, and lever trim. Another wired option is the Schlage 03A electric lock/unlock outside lever mortise lock, keyed outside, with request to exit (RX) and 12/24VDC operation, a heavy duty corridor function. All three take power at the door and are switched by an access control system rather than by an onboard keypad or credential reader.
9) I do not have a card reader or an access control panel at this door. What mortise lock should I use instead of the Sargent 8270?
The Sargent 8270 has an electromechanical lock function and runs on 12 to 24VDC, so it expects power and a switching signal from an access control system. For a standalone opening with no panel, a keypad mortise lock carries its own credentials: the Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with 300 user codes in classroom function, the Alarm Lock DL2700CR is a Grade 1 Trilogy T2 electronic mortise lock in classroom function with a weatherproof design, and the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override. The Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock. These are programmed at the door instead of being wired back to a controller.
10) The opening does not need to be electrified at all. What is the mechanical equivalent of the Sargent 8270 mortise lock?
The Sargent 8270 is the electromechanical fail-safe member of the Sargent 8200 Series, keyed single cylinder with lever trim. For a purely mechanical Grade 1 mortise lock in the same heavy duty class, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. Cal-Royal also offers the NM8070 in classroom function and the NM8050 in office/entrance function with an auxiliary deadlatch. None of these require a power supply, wiring, or a transfer hinge at the door.
11) Which mortise locks look like alternatives to the Sargent 8270 but will not work on an electrified access control opening?
Several mortise products share the word mortise without being electrified locks. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets are dummy function - trim only, with no latch that retracts. The Schlage L0170 is a Grade 1 half dummy trim mortise non-keyed lever lock, heavy duty, for 1-3/4 inch doors. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, and the Hager 3810S and 3810E are Grade 1 passage mortise locks with a 2-3/4 inch backset. The Kaba Ilco 185 Series is a deadbolt mortise lock with no handing. None of these are keyed or take power, while the Sargent 8270 is keyed single cylinder with an electromechanical lock function.
12) Is the Schlage LE Series mobile-enabled mortise lock the same grade as the Sargent 8270?
No. The Schlage Electronics LEBMB-ADD mobile-enabled mortise lock with push button and LED, covering privacy, office, and apartment functions, is Grade 2 with a 3 hour fire rating for 1-3/4 inch doors. The Sargent 8270 is Grade 1. If the specification on the drawing calls for Grade 1 electrified mortise hardware, the LEBMB-ADD does not meet it; the Schlage Electronics LEMD-GRW in the ENGAGE Series is Grade 1 with a 3 hour fire rating, and the Dormakaba E5086 is also Grade 1.
13) Which rose size should I pick on a Sargent 8200 mortise lock for a narrow stile door?
Take the LN rose. At 2 inches (51mm) it is the smallest of the four, against the O rose at 2-3/4 inches (67mm), the E rose at 3-1/16 inches (78mm) and the L rose at 3-1/2 inches (89mm). On a narrow stile aluminum or a door with an adjacent glass stop, the 3-1/2 inch L rose will crowd the stile edge where the 2 inch LN clears it. If you are matching roses already installed elsewhere in the building, measure the existing one and pick the same size.
14) What is the difference between the Sargent 8270 and a standalone keypad mortise lock like the Alarm Lock Trilogy or Schlage CO-100?
Two different access control architectures. The 8270 is a wired electrified lock body with no reader or credential of its own: it takes 12 to 24VDC from an access control panel, and the panel decides who gets in. That is what you want when the building already has a head end and you need door position, egress and audit handled centrally. A standalone unit like the Alarm Lock DL3500CR, a Grade 1 electronic mortise lock with 300 user codes in classroom function, or the Schlage CO-100 standalone electronic mortise lock with keypad reader, carries its own credential database at the door and needs no panel or wire run. Standalone is cheaper to install on a handful of doors; wired scales better across a campus.
15) What is a comparable wired electrified mortise lock to the Sargent 8270 from another brand?
The closest peer is the BEST 45HW Series wired electromechanical mortise lock, which runs the same 12V/24V operation and is a heavy duty mortise body like the 8270. Also in the same wired-to-panel category: the Schlage L9092EU with 03A trim, an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, on 12/24VDC for a 1-3/4 inch door; and the Command Access ML190 Series motorized mortise lock with field selectable EL/EU operation on 24VDC, which lets you set fail-safe or fail-secure in the field rather than committing to one at order time. The 8270 is the fail-safe function specifically.
16) I need a wireless mortise lock instead of running wire to the door. What should I look at?
The 8270 is a hardwired lock and needs a run from a power supply and access control panel to the door, which means a hinge transfer or an electric power transfer on every opening. If the wire pull is the problem, look at the Schlage Electronics LEMD-GRW, a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating, or the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock with keypad, which is built for Adams Rite deadlatches. Wireless saves the conduit; wired gives you real-time control at the panel.
17) I only need a mechanical storeroom or classroom mortise lock, not an electrified one. What is the equivalent?
If there is no access control on the opening, the 8270's electrified function and its 12 to 24VDC supply are cost you do not need. Mechanical Grade 1 mortise locksets that cover the usual functions: the Accentra 8805FL storeroom lock with Arcadia lever, the Cal-Royal NM8080 storeroom lockset with an interchangeable core option, the Cal-Royal NM8070 classroom lockset, and the Corbin Russwin ML2003 Grade 1 classroom lockset. The Cal-Royal and Corbin Russwin bodies are specified for a 1-3/4 inch door.
18) Can I standardize one electrified mortise lock across a hospital or school with different door functions?
Largely, yes. The 8200 Series runs 56 functions covering electromechanical, security and monitoring options, all on the same lock body, so a facility can hold one series and one Sargent key system across corridors, classrooms, offices and stair doors while varying the function door by door. Handing is field reversible and it integrates with all Sargent key systems, so your masterkey chart does not fragment. Lever, rose and finish are picked per opening, which lets you match existing trim on renovation work.
19) Can I order the Sargent 8270 without a cylinder so I can use my own cores?
Yes, three ways. Less cylinder ships the lock with no cylinder at all. The 70 option gives you a small format interchangeable core prep, less core, and the 60 option gives you a large format interchangeable core prep, less core. Pick the prep that matches the cores your facility already stocks, and select None on the keying axis when you go less cylinder. Choose standard cylinder only if you want it keyed here, keyed different, keyed alike or to a supplied key code.
20) Is the Sargent 8270 a wireless lock, and what should I look at if I want credentials managed over a network?
The Sargent 8270 is a wired electromechanical mortise lock running 12 to 24VDC with fail-safe operation, so its access decisions come from the connected system over wiring, not over the air. If the requirement is networked or credential-reading hardware at the door itself, the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile-enabled deadbolt with LED on 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 Accentra NTM623-NR is a Grade 1 nexTouch Generation 3 mortise lock with a capacitive touchscreen keypad, no deadbolt, with cylinder override. Note the LEMD-GRW is supplied right hand, while the Sargent 8270 has field-reversible handing.
21) I need a mortise lock for a behavioral health or ligature-resistant room. Can I use the Sargent 8270?
The Sargent 8270 uses lever trim, offered in A, B, E, F, J, L, P, and W levers, which is a projecting handle. Ligature-resistant openings normally call for purpose-built trim. 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, and the MRX-A-01 is a satin stainless steel ligature-resistant arch trim mortise lockset, also Grade 1 heavy duty passage, for 1-3/4 inch doors. 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. All three are passage function, so pair them with separate security hardware if the room must also lock.
22) How does the Sargent 8270 compare with the Dormakaba E-Plex 5086 for a door that needs both card and code entry?
The Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card mortise lock in a back to back configuration, so the reader and keypad sit on the lock itself. The Sargent 8270 is Grade 1 as well, but it is an electromechanical mortise lock taking 12 to 24VDC from an access control system, with the credential reading handled by whatever reader that system uses at the opening. The Dormakaba PowerPlex P2066 Series is another mortise option in the same family of self-contained locks, and the Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2. Choose between them on where the credential decision is made and what grade the specification calls for.
23) Can I put a Sargent 8270 on an aluminum storefront door with a narrow stile?
The Sargent 8270 is a heavy duty Grade 1 mortise lock with lever trim and rose sizes of 2 inch LN, 2-3/4 inch O, 3-1/16 inch E, and 3-1/2 inch L, sized for standard commercial mortise preps. For aluminum and glass entrances, the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad built for Adams Rite deadlatches, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock listed for wide stile. The Kaba Ilco BR Series is a glass door bottom rail lock for frameless glass doors. Verify the existing stile prep and lock case pocket before ordering either family.
24) I only need to add a deadbolt with keypad control, not a full electrified lockset. What replaces the Sargent 8270 there?
The Sargent 8270 is a keyed single cylinder electromechanical mortise lockset with lever trim, so it handles both latching and access control at the opening. If the door already has working latching hardware and the requirement is only a controlled deadbolt, the Alarm Lock DL4500 Series is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for doors 1-5/8 to 1-7/8 inch thick. The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 to 2 inch thick.
25) The mortise pocket in the door is fine and I only need to swap the lock body. Is the Sargent 8270 sold that way?
The Sargent 8270 is a complete single cylinder mortise lockset ordered with lever, rose, and finish selections, so it comes as trim plus body. If the job calls for a lock body alone, the BEST 45H Series is a heavy duty mortise lock body in public entrance function with field reversible operation, and the BEST 45HCA is a heavy duty mortise lockbody with intruder function. Baldwin supplies the 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies on a 2-1/2 inch backset, the 6301 for doors 1-3/4 inch and over, the 6310 for doors 1-3/8 inch and over, each in knob by knob or lever by lever configuration. Match the backset and case dimensions to the existing pocket before ordering a body on its own.
26) Does a Sargent 8270 fit a 1 inch thick ornamental iron gate door?
The Sargent 8270 is a commercial heavy duty Grade 1 mortise lockset built for standard commercial door preps. For narrow ornamental iron, Marks USA lists the 21AC entrance double cylinder Unilock ornamental iron mortise lock with round knob and the 22AC entrance double cylinder ornamental iron mortise lock with round knob, both for 1 inch door thickness. Those are double cylinder entrance functions keyed both sides, a different operation from the 8270, which is keyed single cylinder.
27) What fire-rated mortise alternatives are there to the Sargent 8270 for a 3 hour rated opening?
The Sargent 8270 is UL 10C fire-rated up to 3 hours with NFPA 80 compliance. Among comparable mortise hardware, the Schlage Electronics LEMD-GRW carries a 3 hour fire rating at Grade 1, and the Schlage Electronics LEBMB-ADD carries a 3 hour fire rating at Grade 2. The Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating in the MA Series. Confirm the rating on the door and frame label matches the hardware rating for the opening.
28) What finishes does the Sargent 8270 lever mortise lock come in?
Sixteen finishes. Brass and bronze: 03 bright brass clear coated, 04 satin brass clear coated, 09 bright bronze clear coated, 10 satin bronze clear coated, 10B dark oxidized satin bronze oil rubbed, 10BE dark oxidized satin bronze, 10BL dark oxidized satin bronze clear coated, and 20D dark statuary bronze lacquered. Nickel and chrome: 14 bright nickel, 15 satin nickel, 26 bright chromium over nickel, 26D satin chromium over nickel. Stainless: 32 bright and 32D satin. Plus BSP black suede and WSP white suede powder coat. For matching a school or hospital corridor already in satin chrome, 26D is the one; 32D satin stainless is the usual pick where the rest of the opening hardware is stainless.
29) Is the Sargent 8270 heavy duty enough for a main entrance or a high traffic corridor?
It is built for exactly that. Grade 1, heavy duty, with UL Cycle Above and Beyond testing completed at 16 million cycles under Verification ID V584148, which is far past what a standard Grade 1 cycle test requires. On a lever-trim opening in a hospital corridor or a school main entrance where the door swings thousands of times a week, that cycle count is the number that matters more than the grade alone.
