Sargent 8227 EA 26D – Frequently Asked Questions

1) What does the Sargent 8227 storeroom function actually do when the door closes?
On the Sargent 8227, the outside lever is always locked. A key in the outside cylinder retracts the latch to get in, and the inside lever always retracts the latch for free egress. It is the closet/storeroom function, single cylinder, with a deadbolt in the lock body. That makes it the standard choice for supply rooms, electrical closets, and tenant storage where the door has to stay secure every time it shuts with nobody having to remember to lock it.
2) Will the Sargent 8227 mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
That is exactly the prep it is built for. The 8227 uses a 2-3/4 inch backset and is designed for 1-3/4 inch door thickness, which is the standard commercial door. If your opening is already cut for an ANSI mortise pocket at 2-3/4 backset, the lock body drops into it. The latchbolt throws 3/4 inch.
3) Can I use the Sargent 8227 on a fire rated storage room door?
Yes. The 8227 is UL 10C positive pressure fire rated up to 3 hours and compliant with NFPA 80. Storeroom function is also the function most fire door assemblies want, since the outside stays locked and the inside lever always gives egress without a key.
4) Do I have to order the Sargent 8227 in a specific hand?
No. Handing on the 8227 is field reversible, so the lock can be changed on site without extra parts or a different part number. One lock covers left and right hand openings, which is why it works well when you are stocking spares for a building rather than ordering per door.
5) What do I need to specify when ordering a Sargent 8227 besides the finish?
Four decisions. Lever style (A, B, E, F, J, L, P or W), rose (E rose at 3-1/16 inch, L rose at 3-1/2 inch, LN rose at 2 inch, or O rose at 2-3/4 inch), finish, and the cylinder arrangement. On cylinder you choose a standard cylinder, less cylinder, 70 prep for small format interchangeable core less core, or 60 prep for large format interchangeable core less core. Then keying: keyed different, keyed alike, or to a specific key code. If you pick less cylinder, select None for keying.
6) Can the Sargent 8227 be keyed into our existing building master key system?
It integrates with all SARGENT key systems, including Degree, Signature, KESO and XC, so it can be master keyed into an existing Sargent system. If your facility runs interchangeable cores, order it with the 70 prep for small format IC or the 60 prep for large format IC, less core, and drop in the cores you already use. Keyed alike is available if you want one key across a bank of storage doors.
7) Does the Sargent 8227 come with a cylinder, or do I order that separately?
Depends how you configure it. Standard Cylinder ships with a conventional Sargent cylinder installed. Less Cylinder ships with none, for locksmiths supplying their own. The 70 option is prepped for a small format interchangeable core and the 60 option for a large format interchangeable core, both less core, so you supply the core from your existing keying stock. If you choose less cylinder, set keying to None.
8) What is the closest Grade 1 storeroom mortise lock to the Sargent 8227 if I need a different brand on the same opening?
The Accentra 8805FL is a Grade 1 storeroom-function mortise lock from the 8800 Series, matching the 8227 on both grade and storeroom function. The Cal-Royal NM8080 is another Grade 1 storeroom mortise lockset, rated for 1-3/4 inch doors and offered with an interchangeable core option. The Sargent 8227 is a Grade 1 closet/storeroom mortise lock with a lever and single-cylinder keying, and it carries a deadbolt in the lock body, which is the main point to confirm against either alternate if the opening was specified with a deadbolt.
9) Can I use a Sargent 8227 where the job calls for keypad or credential access?
No. The 8227 is a mechanical lock with no electronics; access is by key through a single cylinder. For credential or code entry on a mortise prep, the Accentra NTM623-NR is a Grade 1 nexTouch mortise lock with a capacitive touchscreen keypad and cylinder override, the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override, and the TownSteel FME-2000 is a Grade 1 heavy-duty mortise lockset with RFID for 1-3/4 inch doors.
10) Is a Baldwin 6310 mortise lock a drop-in substitute for the Sargent 8227?
It is not a straight swap. The Baldwin 6310 is an entrance/storeroom mortise lock body with a 2-1/2 inch backset for doors 1-3/8 inch and over, while the Sargent 8227 uses a 2-3/4 inch backset on 1-3/4 inch doors. The different backset means a different cross-bore and mortise pocket position, so the existing door prep would have to be verified before substituting either direction.
11) My door is 1-5/8 inch thick. Will the Sargent 8227 work, or do I need something else?
The 8227 is specified for 1-3/4 inch door thickness, so a 1-5/8 inch door falls outside it. The Alarm Lock Trilogy DL3500CR is a Grade 1 classroom mortise lock rated for 1-5/8 to 1-7/8 inch doors, and the DL2700CR Trilogy T2 covers the same 1-5/8 to 1-7/8 inch range with a weatherproof design. Both are electronic keypad locks in classroom function rather than mechanical storeroom, so confirm the function the opening needs.
12) Is a mortise lock like the Sargent 8227 worth it over a cylindrical lockset for a storage room?
For high traffic and high security openings, yes. A mortise body sits inside a pocket in the door edge and carries both a latchbolt and a separate deadbolt, so the door is bolted, not just latched. The 8227 is ANSI/BHMA A156.13 Series 1000 Grade 1 and completed UL cycle testing at 16 million cycles. A bored cylindrical lock such as the Schlage PC10 is faster to install and easier to retrofit into a 161 prep, but it has no deadbolt and less resistance to force on the door edge. If the door is already mortise prepped, stay mortise.
13) Which rose size should I pick for the Sargent 8227 on a narrow stile or a door with existing rose marks?
Four roses are offered: LN at 2 inch, O at 2-3/4 inch, E at 3-1/16 inch, and L at 3-1/2 inch. Go small (LN or O) where the stile is tight or there is a vision lite frame crowding the lock. Go large (E or L) where you are replacing older trim and want the new rose to cover existing holes or wear marks in the finish. Trim style is separate from function, so all four work with the storeroom lock body.
14) Is the Sargent 8227 an electrified lock, and what if I need access control on that door?
The 8227 as configured is a mechanical lock, not electronic. If the opening needs to tie into an access control system, Sargent's 8200 electromechanical version runs on 12 to 24VDC with EcoFlex technology that cuts power draw by up to 96 percent. Other options in the same mortise footprint include the BEST 45HW wired electromechanical mortise lock at 12V/24V, or the Schlage L9092EU electric unlock mortise lock with request to exit at 12/24VDC.
15) Is the Sargent 8227 the right lock for a classroom door?
No. Storeroom function keeps the outside lever locked at all times, so a teacher cannot unlock the door from inside the room and cannot control it without a key on the outside. For a classroom opening look at a classroom function mortise lock such as the Corbin Russwin ML2003 or the Cal-Royal NM8070, both Grade 1 for 1-3/4 inch doors. If the requirement is classroom security with an indicator, the Marks USA LA318GJ covers that.
16) Will the Sargent 8227 hold up in a high traffic commercial corridor?
It is a heavy duty commercial lock, Grade 1, and Sargent completed UL Cycle Above and Beyond testing at 16 million cycles (Verification ID V584148). Grade 1 is the top ANSI/BHMA commercial tier. For a building where the same door gets pulled hundreds of times a day, that cycle number is the figure to put in front of a facilities director.
17) Which mortise lock should I use for a bathroom or bedroom door where the Sargent 8227 is too much lock?
The 8227 is keyed with a single cylinder for closet and storeroom openings, so it is the wrong function for a privacy door. 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 covering 1-3/4 to 2 inch doors.
18) If the opening does not need to be keyed at all, what is the simpler alternative to the Sargent 8227?
For a non-keyed opening, the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock that is field reversible and fire rated. Both drop the cylinder and deadbolt entirely; the Sargent 8227 is a keyed single-cylinder lock with a deadbolt, so it is only worth specifying where the door actually has to secure.
19) What looks like an alternative to the Sargent 8227 but will not actually secure the door?
Several mortise items in the same size class do no locking at all. The Schlage L0170 is a half dummy trim, Grade 1 non-keyed, and the Emtek 3102 Memphis and 3104 Hamilton mortise entrance locksets are dummy function. These provide the lever or handle appearance only. The Sargent 8227 is a keyed closet/storeroom lock with a deadbolt, so a dummy is only correct on the inactive leaf of a pair or a false door.
20) I need an electrified mortise lock on a storeroom opening instead of the mechanical Sargent 8227. What are my options?
The Command Access ML190 Series ML19092-M is a heavy-duty storeroom-function motorized mortise lock with field selectable fail safe or fail secure operation at 24VDC. The BEST 45HW Series is a heavy-duty wired electromechanical mortise lock running 12V or 24V. The Sargent 8227 itself is a mechanical, non-electronic lock, so either of those is the route if the door is on an access control system.
21) Is there a mortise lock alternative to the Sargent 8227 for a behavioral health or ligature-resistant application?
Yes, but only in passage function. The TownSteel MRX-L-01 is a Grade 1 heavy-duty anti-ligature stainless steel lever mortise lockset for 1-3/4 inch doors, and the MRX-A-01 is the same passage function with ligature-resistant arch trim. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant. The Sargent 8227 is a keyed closet/storeroom lever lock and is not a ligature-resistant design.
22) What is the difference between the Sargent 8227 and a mortise deadbolt like the Kaba Ilco 185?
The Kaba Ilco 185 Series is a deadbolt-function mortise lock with no handing, so it throws a bolt and nothing more, leaving the door to be pulled or latched by separate hardware. The Alarm Lock DL4500 is likewise a deadbolt-only electronic mortise unit. The Sargent 8227 combines a latchbolt operated by the lever with a deadbolt in one lock body, so it handles both latching and deadbolting in a single mortise pocket.
23) For an office door where the lever should be left unlocked during business hours, is the Sargent 8227 the right lock?
No. Closet/storeroom function keeps the outside lever locked continuously, so it cannot be left in a passage state. For an office opening, the Cal-Royal NM8050 is a Grade 1 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 on a 2-3/4 inch backset.
24) Do I need the Sargent 8227 mortise lock, or will a cylindrical lock do the job?
That depends on the door prep. The 8227 requires a mortise pocket in the edge of the door. If the doors are prepped for a bored lock instead, the Schlage PC10 is a Grade 1 passage cylindrical lock with rose for 1-3/4 inch doors. A mortise lock and a cylindrical lock are not interchangeable in an existing prep, so verify what the door is already cut for before ordering either.
25) Is there a Grade 1 mortise option with a classroom intruder or lockdown function instead of the Sargent 8227 storeroom?
Yes. The BEST 45HCA Series 45HCAINL is a heavy-duty mortise lockbody with intruder function, and the TownSteel FME-4000 is a Grade 1 heavy-duty electronic intruder classroom mortise lockset with RFID for 1-3/4 inch doors. The Sargent 8227 is closet/storeroom function, which locks the outside lever permanently and has no inside lockdown control, so it does not satisfy a classroom lockdown requirement.
26) What finishes does the Sargent 8227 come in for matching existing hardware in a building?
Sixteen finishes, so most existing schedules can be matched: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized satin bronze, 10BE and 10BL dark oxidized bronze variants, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze, 26 bright chrome, 26D satin chrome, 32 bright stainless, 32D satin stainless, plus BSP black suede and WSP white suede powder coat. 26D and 32D are the usual commercial standards if you are standardizing a facility.
