Sargent 8229 EA 32 – Frequently Asked Questions

1) What does the Sargent 8229 dummy trim deadlock function actually do?
The 8229 is a deadbolt-only mortise lock: the deadbolt is thrown and retracted by key from either side (double cylinder), and the lever trim is dummy, meaning it is fixed and does not retract any latch. There is no latchbolt operation from the lever. Use it where you want a keyed deadbolt on the opening with matching lever appearance, not where someone needs to turn a lever to get through. If the lever has to operate a latch, you need a different 8200 function.
2) Is a double cylinder deadbolt like the Sargent 8229 allowed on a fire door egress opening?
Both sides are key operated, so there is no thumbturn and no free egress from the inside. On a required means of egress, a double cylinder deadbolt is generally not permitted by code, and your AHJ will call it. The 8229 lock body itself is Grade 1 and UL 10C fire rated up to 3 hours with NFPA 80 compliance, so the hardware is fire door rated, but rating and egress are two separate questions. Typical use is a storage room, mechanical room, vestibule, or secondary door that is not counted for egress.
3) Will the Sargent 8229 fit my existing mortise pocket and 1-3/4 inch door?
It is built for 1-3/4 inch doors with a 2-3/4 inch backset, which is the standard commercial mortise prep. Bolt throw is 3/4 inch. If your existing pocket is a standard ANSI mortise cutout at 2-3/4 backset you are in the right family; if the door is thinner or thicker than 1-3/4, or the prep is at a 2-1/2 inch backset like the Baldwin 6301 bodies, this is not a drop-in.
4) What do I have to specify besides finish when ordering the Sargent 8229?
Four decisions. Cylinder: standard cylinder, less cylinder, 70 small format interchangeable core prep less core, or 60 large format interchangeable core prep less core. Keying: keyed different, keyed alike, or to a key code (pick None if you chose less cylinder, and enter the code in the key code field if you are matching an existing system). Lever: 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. Finish is chosen from 16 options.
5) Can I key the Sargent 8229 into the Sargent master key system already in my building?
Yes. The 8200 Series works with all Sargent key systems, including Degree, Signature, KESO and XC. If you are folding it into an existing system, order it with the interchangeable core prep that matches your program, 70 for small format or 60 for large format, both supplied less core so your locksmith drops your own cores in. For a standalone door, take a standard cylinder keyed different, or keyed alike if several doors should share one key.
6) I need a working latch, not a dummy - what Grade 1 mortise lock should I order instead of the 8229?
The 8229 is a dummy trim deadlock function, so the lever does not retract a latch. For an operating latch in a Grade 1 mortise body, the Accentra 8805FL is a storeroom function mortise lock, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset, also 1-3/4 inch. Pick by who needs to be locked out: storeroom for always-locked outside with free egress, office for a lever that can be locked from inside, classroom for key-controlled outside lever.
7) What is the closest equivalent to the Sargent 8229 if I need a dummy mortise trim from another manufacturer?
The Schlage L0170 is the nearest match in intent: it is a Grade 1 heavy duty mortise lever lock in dummy function, non-keyed, for 1-3/4 inch doors. The difference is the deadbolt. The Sargent 8229 is a dummy trim deadlock with a double cylinder keyed deadbolt, so the lever is inoperative but the bolt is still key-operated from both sides. The L0170 is half dummy trim with no keyed function at all. Use the L0170 where you only need a pull on an inactive leaf, and the 8229 where that inactive leaf still has to be bolted and keyed.
8) What should I use instead of the 8229 on a privacy door like a restroom or bedroom?
A dummy trim deadlock is not a privacy function - the 8229 lever does not operate and the bolt is keyed from both sides, which is the wrong behavior for a room someone occupies. For privacy, the Cal-Royal NM8440 is a 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 inches thick. Both give the occupant inside control the 8229 does not.
9) Our doors are 2-1/2 inch backset prep - can I still use the 8229?
The Sargent 8229 is built around a 2-3/4 inch backset with 1-3/4 inch door thickness, so a 2-1/2 inch backset pocket is a different prep. Baldwin's 6301 lever by lever and 6310 lever mortise lock bodies are 2-1/2 inch backset units, the 6301 in entrance/apartment function for doors 1-3/4 inch and over and the 6310 in entrance/storeroom function for doors 1-3/8 inch and over. Measure from the door edge to the center of the cylinder before committing either way.
10) Does handing matter when ordering the Sargent 8229 mortise lock?
Handing is not a separate ordering decision here. The 8200 Series body is field reversible at the standard 2-3/4 inch backset, so one part number covers left and right hand openings. That is useful for a property manager stocking spares across a building instead of carrying two versions.
11) Which rose size should I pick for the Sargent 8229 on a narrow stile or a door with old trim scars?
Four rose sizes are offered: LN at 2 inches, O at 2-3/4 inches, E at 3-1/16 inches and L at 3-1/2 inches. Go small with LN or O when stile width is tight or you want a minimal look. Go with the 3-1/2 inch L rose when you are covering the footprint of previous hardware on a replacement door, since the larger plate hides more of the old finish ring.
12) Is the Sargent 8229 durable enough for a high traffic commercial corridor?
It is a heavy duty, ANSI/BHMA Grade 1 commercial lock, and Sargent completed UL Cycle Above and Beyond testing on the 8200 body at 16 million cycles. That is well past what a typical office or school corridor door sees in its service life. Note that on the 8229 the levers are dummy and the deadbolt is key operated, so cycle wear falls on the bolt and cylinder rather than a latch mechanism.
13) We need the outside lever to unlock electrically - what replaces the 8229 for access control?
The 8229 is a mechanical dummy trim deadlock and is not an electronic unit. For an electrically controlled mortise lock, the Schlage L9092EU 03A is a heavy duty electric lock/unlock outside lever mortise lock with keyed outside and request to exit, 12/24VDC, for 1-3/4 inch doors; the Command Access ML190 is a heavy duty motorized mortise lock with field selectable EL/EU operation on 24VDC in storeroom function; and the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation. Field selectable EL/EU on the ML190 lets you decide fail safe or fail secure at install.
14) Are the Emtek dummy mortise locksets a substitute for the Sargent 8229?
They serve a different door. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are all dummy function mortise entrance locksets in decorative residential trim. The Sargent 8229 is a commercial Grade 1 heavy duty mortise unit with a keyed double cylinder deadbolt behind the dummy trim. If the opening is a residential or decorative inactive leaf with no bolt required, the Emtek dummies fit. If the inactive leaf has to be bolted and keyed on a commercial opening, they are not an exchange.
15) If all I need is a keyed deadbolt in a mortise pocket, is there a simpler option than the 8229?
Yes. The Kaba Ilco 185 Series mortise lock is a deadbolt function unit supplied with no handing, which covers a mortise pocket that only needs a bolt and no lever trim at all. The Sargent 8229 carries a deadbolt as well, double cylinder and keyed, but it also carries full dummy lever trim in a choice of lever and rose styles. Choose the 185 when the door takes no lever; choose the 8229 when the opening still needs matching lever trim to look like the doors beside it.
16) Can I use a passage mortise lock in place of the Sargent 8229?
Only if the opening needs a working, always-unlocked lever and no bolt. The Falcon MA101 is a Grade 1 heavy duty fire rated passage mortise lock with field reversible operation, the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, and the Hager 3810S is a passage mortise lock with rose trim and a 2-3/4 inch backset. All three retract a latch when you turn the lever. The 8229 lever is dummy trim and retracts nothing; its security comes from the double cylinder deadbolt. They are not interchangeable on an opening that must be bolted.
17) We want keypad access on the door instead of the 8229's keyed deadbolt - what mortise locks cover that?
The 8229 is a mechanical, non-electronic unit keyed on both sides. For credential access in a mortise pocket, 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 Schlage CO-100-MS is a Grade 1 heavy duty standalone electronic mortise lock with keypad reader for 1-3/4 inch doors, and the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors. Confirm door thickness first, since the Alarm Lock range differs from the other two.
18) Is the Falcon MESC600DT dummy trim an alternative to the Sargent 8229?
No - they mount to different things. The Falcon MESC600DT is a fire rated dummy escutcheon lever trim made for M9900 Series exit devices, so it dresses a door that already carries an exit device. The Sargent 8229 is a mortise lock unit with dummy trim and a double cylinder deadbolt that sits in a mortise pocket in the door edge. Order the MESC600DT only when an M9900 device is on the door.
19) For a behavioral health or anti-ligature opening, is the 8229 the right mortise lock?
The 8229 uses standard lever trim in A, B, E, F, J, L, P and W lever styles, which is conventional projecting trim. For ligature resistant openings the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with arch trim in satin stainless, and the Marks USA MAR5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant. All three are passage function, so pair them with separate locking hardware if the door must secure.
20) Does the Schlage PC10 work as a replacement for the Sargent 8229?
No, the door prep is different. The Schlage PC10 is a Grade 1 passage cylindrical lock with rose for 1-3/4 inch doors, which bores through the door face. The Sargent 8229 is a mortise lock that requires a pocket routed into the door edge. Swapping between them means changing the door prep, not just the hardware.
21) Our doors are aluminum storefront with narrow stiles - will the 8229 fit, and what else is there?
The Sargent 8229 is specified for 1-3/4 inch door thickness with a 2-3/4 inch backset, which is a standard commercial door prep rather than a narrow stile aluminum prep. For aluminum openings, the Alarm Lock DL1300NW is an electronic mortise lock with keypad made for Adams Rite deadlatches, the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock in a wide stile configuration, and the Kaba Ilco BR Series is a glass door bottom rail lock. Match the existing stile and rail before ordering.
22) Can I match the Sargent 8229 to the stainless and bronze hardware already on my other doors?
Finish coverage is broad enough to match most existing commercial schedules: 32D satin stainless and 26D satin chrome for typical institutional work, 10B oil rubbed dark oxidized satin bronze plus 10BE and 10BL variants, 20D dark statuary bronze, 03 and 04 brass, 09 and 10 bronze, 14 and 15 nickel, 26 bright chrome, 32 bright stainless, and BSP black or WSP white suede powder coat. Match the BHMA finish code on your existing hardware rather than the color name.
23) What is the difference between ordering the Sargent 8229 and a bare mortise lock body like the BEST 45H?
The BEST 45HCAC is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCAINL is a heavy duty lock body in intruder function - both are the body itself, so trim is specified separately. The Sargent 8229 is supplied as a trimmed unit: you select lever style, rose style and finish along with the cylinder and keying. If you already have matching trim on the job, a bare body keeps it consistent; if you are dressing the door from scratch, the 8229 covers both in one order.
