Sargent 8228 EA 26D – Frequently Asked Questions

1) Does the Sargent 8228 mortise lock actually latch, or is it dummy trim only?
The 8228 is a dummy trim deadlock function. The lever is fixed trim, it doesn't retract a latchbolt. What operates is the deadbolt, thrown and retracted by the key from the outside cylinder. Use it where you want a pull-style lever look on the door and key-controlled deadbolt security, not on an opening that needs a latching function. If you need a latching lockset in a mortise body, look at a storeroom or office function instead, such as the Cal-Royal NM8080 storeroom mortise lockset or the Corbin Russwin ML2003 classroom lockset.
2) Will the Sargent 8228 fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
Yes, that is exactly the prep it's built for. The 8228 mortise lock uses a 2-3/4 inch backset and is specified for 1-3/4 inch door thickness, which is the standard commercial door. If your existing pocket is a standard ANSI mortise prep at 2-3/4 backset, the body drops in.
3) Is the Sargent 8228 fire rated for a labeled opening?
UL 10C fire rated up to 3 hours with positive pressure certification, and NFPA 80 compliant. It also carries ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and is ADA compliant, so it clears the usual specification hurdles on a labeled commercial opening.
4) What do I have to specify when ordering a Sargent 8228 mortise lock?
Four things beyond finish. Lever design (A, B, E, F, J, L, P or W), rose (E at 3-1/16 inch, L at 3-1/2 inch, LN at 2 inch, or O at 2-3/4 inch), cylinder, and keying. On the cylinder you choose standard cylinder, less cylinder, 70 for small format interchangeable core prep less core, or 60 for large format interchangeable core prep less core. Keying is keyed different, keyed alike, or a specific key code you supply; if you order less cylinder, select None on keying.
5) Can I key the Sargent 8228 into my existing Sargent master key system?
Yes. The 8228 works with all SARGENT key systems, including Degree, Signature, KESO and XC, in 6 pin or 7 pin cylinders. If your building is already on a Sargent system, order it keyed alike to your existing group or supply the key code at checkout. If your keying is done by a locksmith after delivery, order it less cylinder, or with 70 small format or 60 large format interchangeable core prep so a core from your own system drops straight in.
6) Is the Sargent 8228 an electrified lock, and does it need power run to the door?
No power needed. The 8228 is a mechanical lock, no wiring, no transfer hinge, no power supply. Sargent does offer electromechanical functions elsewhere in the 8200 Series with EcoFlex power management running on 12 to 24VDC, but that is a different function code. If your opening needs electric lock/unlock, look at an electrified mortise lock such as the Command Access ML190 Series motorized mortise lock with field selectable EL/EU operation, or the Schlage L9092EU with request-to-exit.
7) What is the closest equivalent to a Sargent 8228 dummy mortise trim from another manufacturer?
The Schlage L0170 half dummy trim is the nearest match. It is a Grade 1 heavy duty mortise non-keyed lever lock in the L Series with a dummy function, fitting 1-3/4 inch doors. The Sargent 8228 is a Grade 1 heavy duty mortise dummy trim deadlock with a lever handle. The practical difference is that the Schlage L0170 is non-keyed, while the 8228 is a keyed single cylinder unit with a deadbolt, so it accepts a cylinder and throws a bolt where the L0170 is fixed trim only.
8) Our doors are 1-5/8 to 1-7/8 inches - does the Sargent 8228 fit, or is there a better match?
The Sargent 8228 is built for 1-3/4 inch door thickness with a 2-3/4 inch backset. If the fleet spans 1-5/8 to 1-7/8 inches, the Alarm Lock DL2700CR Grade 1 classroom mortise lock, the DL3500CR Grade 1 classroom mortise lock and the DL4500 Grade 1 mortise deadbolt all list a 1-5/8 to 1-7/8 inch door thickness range. Those are electronic keypad units, so they change how the door is operated as well as what it fits.
9) What should I use instead of a Sargent 8228 if the door needs to latch and lock rather than carry fixed trim?
Pick a lock body with a working function. For a storeroom opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. For a classroom, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors. The Sargent 8228 is a dummy trim deadlock function, so its trim does not retract a latch.
10) Can I use a Baldwin 6301 or 6310 mortise lock body where a Sargent 8228 is specified?
Check the backset before you do. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies both use a 2-1/2 inch backset, with the 6301 rated for 1-3/4 inch doors and over and the 6310 for 1-3/8 inch and over. The Sargent 8228 uses a 2-3/4 inch backset on a 1-3/4 inch door. A 2-1/2 inch backset body will not drop into a pocket cut for 2-3/4 inch without rework to the door prep.
11) Does the Sargent 8228 need to be ordered handed?
No. Handing is field reversible on the 8200 Series mortise lock, so one part number covers left and right hand openings. That matters for a property manager stocking spares, one lock covers any door in the building.
12) Is the Sargent 8228 durable enough for a high traffic entrance?
It's a heavy duty commercial mortise lock, Grade 1, and Sargent completed UL Cycle Above and Beyond testing at 16 million cycles on the 8200 Series. That's the reason it gets specified on school, hospital and office corridor doors rather than a lighter bored lock.
13) Which rose size should I pick to cover the old holes on my door?
Four rose sizes are offered on the 8200 Series: LN at 2 inches, O at 2-3/4 inches, E at 3-1/16 inches, and L at 3-1/2 inches. If you're replacing existing trim and there's wear or old fastener holes around the spindle, step up to the L rose at 3-1/2 inches for the widest coverage. The LN at 2 inches is the smallest footprint and shows the most of what's behind it.
14) I need a mortise deadbolt only, no lever. Is the 8228 the right part?
Not quite. The 8228 comes with lever trim and rose as part of the assembly, it's a dummy lever plus deadlock. For a straight mortise deadbolt with no lever at all, the Kaba Ilco 185 Series mortise lock is a deadbolt function with no handing to specify. On the electronic side, the Alarm Lock DL4500 Series is a Grade 1 mortise deadbolt with a keypad.
15) Can I standardize a whole facility on the Sargent 8200 Series and still get different functions on different doors?
Yes, that's the usual reason people spec it. The 8200 Series covers 56 different functions, including electromechanical, security and monitoring options, all on the same lock body platform and the same 2-3/4 inch backset prep. So the classroom doors, the storerooms, and the dummy trim openings all take the same door prep, the same lever and rose designs, and the same key system. You change function without changing the mortise pocket or the trim look.
16) Does the Sargent 8228 come with a cylinder, or do I order that separately?
Depends how you order it. Standard cylinder ships with the lock. Choosing less cylinder means you supply your own. The 70 option gives you a small format interchangeable core prep less core, and 60 gives large format interchangeable core prep less core, both for facilities that stock their own cores. If you pick any of the less-cylinder routes, set keying to None; the lock arrives ready for your core.
17) Are the Emtek 3102 Memphis and Sargent 8228 interchangeable as dummy mortise trim?
They both carry a dummy function, but they serve different openings. The Emtek 3102 Memphis is a decorative mortise entrance lockset in dummy form, as are the Emtek 3019 Brisbane, 3104 Hamilton and 3106 Manhattan. The Sargent 8228 is a Grade 1 heavy duty commercial unit with a keyed single cylinder and deadbolt, offered across levers A, B, E, F, J, L, P and W with E, L, LN and O rose sizes. Where the specification calls for a Grade 1 commercial mortise, the Emtek dummy sets do not carry that rating.
18) Is the Falcon MESC600DT dummy trim a substitute for a Sargent 8228?
No. The Falcon MESC600DT is dummy escutcheon lever trim built for M9900 Series exit devices, so it mounts to an exit device rather than into a mortise pocket. The Sargent 8228 is a mortise lock type installed in a mortised door prep with rose trim in E, L, LN or O sizes. If the door carries an exit device, the MESC600DT is the correct family; if it carries a mortise prep, it is not.
19) Is there a Grade 1 mortise alternative to the Sargent 8228 for a bed or bath door needing privacy and a bolt?
Yes. The Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a 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 inches. Both operate the bolt from the inside for privacy. The Sargent 8228 throws its deadbolt from a keyed single cylinder, which suits key control rather than occupant privacy.
20) We want keypad or credential access on the same opening - what replaces a Sargent 8228?
The 8228 is a non-electronic mortise unit. For credential access on a mortise prep, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating, and the Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton and card mortise lock. Each of these operates the door electronically, where the 8228 is mechanical dummy trim with a key-thrown deadbolt.
21) For a behavioral health or anti-ligature opening, what mortise lockset should I look at instead of the Sargent 8228?
The TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset with a passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function with ligature resistant arch trim in satin stainless steel. 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. The Sargent 8228 uses conventional lever trim in levers A, B, E, F, J, L, P and W, which is not a ligature resistant profile.
22) Is a Kaba Ilco 185 mortise deadbolt the same thing as a Sargent 8228?
No, though both involve a deadbolt. The Kaba Ilco 185 Series is a mortise deadbolt function with no handing, supplied as a bolt unit without lever trim. The Sargent 8228 is a dummy trim deadlock combining a keyed single cylinder deadbolt with lever trim, available in E, L, LN and O rose sizes and finishes from 03 bright brass through 32D satin stainless and BSP black suede powder coat. Specify the 185 when the opening needs a bolt alone and the 8228 when it needs a bolt plus fixed lever trim.
23) What mortise lock would a distributor cross the Sargent 8228 against for an office or entrance opening?
The Cal-Royal NM8050 is a Grade 1 heavy duty office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches. Both share the 8228's Grade 1 rating and lever trim, but they latch the door; the Sargent 8228 is a dummy trim deadlock with a keyed single cylinder.
24) The opening needs an electrified mortise lock on 12 to 24VDC - what should I specify instead of the Sargent 8228?
Look at a purpose-built electrified body. The BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation, the Command Access ML190 is a heavy-duty storeroom mortise lock with field selectable EL/EU operation on 24VDC, and the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside with request to exit, on 12/24VDC for 1-3/4 inch doors. The Sargent 8228 as configured is non-electronic dummy trim.
25) Is a Schlage PC10 cylindrical passage lock an acceptable stand-in for a Sargent 8228?
Not on the same door prep. The Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with a rose, for 1-3/4 inch doors, and a cylindrical lock installs through bored holes. The Sargent 8228 is a mortise lock requiring a mortise pocket in the door edge. Both are Grade 1 on 1-3/4 inch doors, but the door prep is not shared, so one cannot replace the other without changing the door.
26) Can I get the Sargent 8228 in a finish that matches the rest of my building hardware?
Sixteen finishes are offered on the 8228: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BE, 10BL, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze, 26 bright chrome, 26D satin chrome, 32 bright stainless, 32D satin stainless, BSP black suede powder coat and WSP white suede powder coat. Most commercial buildings standardize on 26D or 32D.
