Sargent 8205-LNB-26D-LC – Frequently Asked Questions

1) Will the Sargent 8200 lock work with the Sargent keys already cut for my building?
Very likely, and that is the point of buying it less cylinder. The 8200 lockbody accepts all cylinder formats, fixed core and interchangeable core, and works with Degree, Signature, KESO and other major commercial key systems. You match the cylinder to the keyway and system already in the building, and the lock takes it. This is how you standardize a facility without rekeying the whole master system.
2) Which Sargent 8200 function do I order for a classroom door versus an office door?
Four functions are orderable here. For an office or entry door, the 8205: outside lever is locked and unlocked by key, inside lever always free. For a classroom, the 8237: outside lever locked and unlocked by key only, with no inside control of the outside lever, which is what keeps a student from locking down a room. For dorm rooms and exit doors, the 8225 locks the outside lever by key or thumbturn with the inside lever always free for egress; the 8245 is the other dormitory/exit variant. All four are keyed functions, so all four need a cylinder supplied.
3) Is the Sargent 8200 mortise lock handed, or can I reverse it on site?
Handing is not something you specify. The 8200 is field reversible, and the handing is changed on site without special tools. For a property manager or contractor stocking spares across a building, that means one part number covers left and right hand openings instead of two.
4) What mortise lock works with an access control system that has to unlock the lever electrically?
The Sargent 8200 Series functions offered are mechanical and key operated. For an electrically controlled opening, the Command Access ML190 is a heavy duty motorized mortise lock with field selectable fail safe or fail secure operation on 24VDC in storeroom function, the BEST 45HW is a heavy duty wired electromechanical mortise lock running 12V or 24V, and the Schlage L9092EU with 03A trim is a heavy duty mortise lock that electrically locks and unlocks the outside lever with request to exit on 12/24VDC.
5) Is there a Grade 1 mortise lock for an office door that comes as a complete set instead of less cylinder?
The Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch, built for 1-3/4 inch doors. The Sargent 8205 office/entry function ships less cylinder, which lets it take fixed core or interchangeable core cylinders in Degree, Signature, KESO and other major commercial key systems. Choose the Sargent when the opening has to join an existing keyway, the Cal-Royal when the door stands on its own.
6) I need a mortise lock on a bathroom door that locks from inside without a key. Which one?
That is privacy function, which the Sargent 8200 Series office, classroom and dormitory/exit functions do not cover. The Cal-Royal NM8440 is a heavy duty 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 thick.
7) What is the electronic equivalent of a Sargent 8200 classroom mortise lock?
For a classroom door managed by codes rather than keys, the Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with classroom function and 300 user codes for doors 1-5/8 to 1-7/8 inches thick, and the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors. The Sargent 8200 Series is a mechanical lock with no electronics, keyed through a cylinder you supply.
8) Which mortise lock lets me lock a classroom door from inside during a lockdown?
That is intruder function, which the Sargent 8237 classroom function does not provide - it has no inside control of the outside lever. The BEST 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.
9) What mortise lock should I use on a behavioral health or patient room door instead of a lever lock?
Lever trim is a ligature point in those rooms. The TownSteel MRX-A-01 is a Grade 1 heavy duty ligature resistant arch trim mortise lockset in satin stainless for 1-3/4 inch doors, the MRX-L-01 is the Grade 1 anti-ligature lever version, both passage function, 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. The Sargent 8200 Series uses B, J, L or P lever trim.
10) Can I put a Sargent 8200 on an aluminum storefront door?
The Sargent 8200 Series is a heavy duty commercial mortise lock with an LN sectional rose and lever trim. For narrow aluminum openings the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad made for Adams Rite deadlatches, the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock built for wide stile, and the Kaba Ilco BR Series is a glass door bottom rail lock.
11) What lever styles and finish does the Sargent LC-8200 with LN rose come in?
Four lever designs, B, J, L and P, all on the LN sectional rose and all in 26D satin chromium plated over nickel. Every one of the four levers is available with every one of the four functions, so you can run the same lever design across office, classroom and dorm doors on a floor and have the trim match. The wider 8200 Series runs to 14 finishes if 26D is not what the rest of your building uses.
12) Should I use a mortise lock or a cylindrical lever lock on a commercial entrance?
A mortise lock like the 8200 goes into a pocket routed into the door edge and carries the whole latch and lock mechanism inside a steel case, which is why it takes Grade 1 loads and why one body can be built into 26 different mechanical functions. A cylindrical lever, such as the Schlage PC10 Grade 1 passage, drops into a bored hole and is quicker to install and to replace, but you are limited to what that chassis does. Choose mortise where the door is a main entrance, a classroom or a dorm door that needs a specific keyed function and long service life; choose cylindrical for interior passage and closet doors where a bored prep is already in the door.
13) I need a storeroom function mortise lock, not office or classroom. What do I order?
Storeroom is not one of the four functions offered on the LC-8200 with LN rose (those are office/entry, classroom, and two dormitory/exit versions). For a Grade 1 storeroom mortise, the Accentra 8805FL from the 8800 Series comes with the Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. Both keep the outside lever always locked with key retraction, which is what a storeroom door needs.
14) What is a comparable Grade 1 classroom mortise lock to the Sargent 8237 from another brand?
The closest straight equivalent is the Corbin Russwin ML2003 Grade 1 mortise classroom lockset from the ML2000 Series, rated for 1-3/4 inch doors. Cal-Royal's NM8070 is another Grade 1 classroom mortise, also 1-3/4 inch, with an auxiliary deadlatch. Both are mechanical like the Sargent. If the specification calls for credential access rather than a key, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise with RFID.
15) Our doors are warped and the latch drags. Will a Sargent 8200 still operate?
That case is designed for it. The 8200's latch keeps retracting on out-of-square and binding doors, and the lock is tested retracting the latch under a 100 lb preload, twice the ANSI/BHMA A156.2 requirement. The push/turn button is also built to survive being driven into a door stop or wall, which is where a lot of maintenance callbacks on older buildings come from.
16) What is a simpler mortise lock for a door that does not need to lock at all?
A passage lock is the simpler choice on a corridor or closet door with no keying. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series that is field reversible and fire rated, and the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors. The Sargent 8200 Series is keyed in every function offered, so it carries cylinder prep those two do not need.
17) Is the Schlage L0170 a substitute for a Sargent 8200 mortise lock?
No. The L0170 is Grade 1 heavy duty half dummy trim in the L Series, non-keyed with no latch - it mounts a lever on an inactive leaf. The Sargent 8200 Series is a keyed mortise lockbody with a working latch in office/entry, classroom and dormitory/exit functions. The same holds for the Emtek Brisbane 3019, Memphis 3102, Hamilton 3104 and Manhattan 3106, which are all dummy function.
18) Will a Kaba Ilco 185 mortise lock do the same job as a Sargent 8225?
No. The Ilco 185 Series is a deadbolt function mortise lock with no handing. The Sargent 8225 dormitory/exit function is a latching lever lock where the outside lever is locked by key or thumbturn and the inside lever stays free for egress. If you want a keypad deadbolt instead, the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes for 1-5/8 to 1-7/8 inch doors.
19) What is the difference between a Sargent 8200 and a Hager 3850E office mortise lock?
The Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon trim, non-keyed, on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches thick. The Sargent 8205 office/entry function is keyed - the outside lever is locked and unlocked by key while the inside lever is always free - and carries LN sectional rose trim rather than an escutcheon. Hager also lists the 3810S passage version with a rose and the 3810E with an escutcheon.
20) Is a Baldwin 6301 mortise lock body an alternative to a Sargent 8200 for an apartment door?
The Baldwin 6301 is an entrance/apartment function mortise lock body on a 2-1/2 inch backset for doors 1-3/4 inches and over, offered knob by knob or as the 6301LS lever by lever. The Sargent 8200 Series is Grade 1 heavy duty for commercial openings, field reversible, and ships less cylinder so it can be keyed into an existing commercial system. Baldwin also lists the 6310 entrance/storeroom body for doors 1-3/8 inches and over.
21) Which mortise lock takes credentials on a phone instead of a key?
The Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader, mobile enabled with Greenwich trim and a 3 hour fire rating, right hand. The Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, and the Accentra nexTouch NTM623-NR is a Grade 1 mortise lock with a capacitive touchscreen keypad and cylinder override. The Sargent 8200 Series is mechanical and field reversible for either hand.
22) What mortise lock body should I order for a public entrance door that is always latched but never locked from outside?
The BEST 45H is a heavy duty mortise lock body in public entrance function with field reversible operation. The Sargent 8200 Series is also field reversible, but the functions it covers are office/entry, classroom and dormitory/exit, all of which lock the outside lever by key. Public entrance keeps the outside lever always free.
23) Is a cylindrical lock an option instead of a mortise lock for a passage door?
Yes, on a door prepped for a bored hole rather than a mortise pocket. The Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with a rose for 1-3/4 inch doors. The Sargent 8200 Series needs a mortise pocket in the door edge, and the 7800/8200 installation template covers that prep.
24) We need an antimicrobial lever finish for a hospital wing. Is that available on the Sargent 8200?
Sargent offers Microshield antimicrobial coating as an optional finish treatment on the 8200 for healthcare, education and other high-touch environments. It is a coating option, not the standard 26D satin chromium supplied here, so it has to be called out when the order is placed rather than assumed.
25) Which electronic mortise lock does not need battery changes or wiring?
The Dormakaba PowerPlex P2066 Series mortise lock is the self powered option in that family, alongside the E-Plex 2066 electronic pushbutton keyless mortise lock and the E-Plex E5086, a Grade 1 back to back entry/egress pushbutton and card lock. The Sargent 8200 Series avoids the question entirely - it is a mechanical Grade 1 lock with no electronics, operated by the cylinder you specify.
