Sargent 8205 LE1A 26D – Frequently Asked Questions

1) Will the Sargent 8205 mortise lock work on a pair of doors or a door that gets constant traffic all day?
High traffic is where the 8200 Series belongs. The 8205 is a Grade 1 heavy duty mortise lock certified to ANSI/BHMA A156.13 Series 1000, and Sargent completed the UL Cycle Above and Beyond test on it at 16 million cycles. For a main entrance, a corridor door, or a tenant suite door in an office building or school, that cycle count is the number that separates a mortise lock from a cylindrical one. Handing is field reversible, so one lock covers either swing on a pair.
2) What does the 8205 office/entry function actually do when someone locks it?
Office/entry is the function you want on a suite or office door that gets locked from inside without a key. The outside lever is locked or unlocked by the key from outside, and the inside lever always retracts the latch for free egress. The 8205 is single cylinder, so there is one keyed cylinder on the outside face only. If you need a door that stays locked outside at all times and can only be released by key, that is storeroom function instead, not this one.
3) I already have a Sargent master key system in the building. Will this lock key into it?
It will. The 8205 accepts all SARGENT key systems, including Degree, Signature, KESO and XC, so a lock ordered with a standard cylinder can be keyed into the existing system rather than run as a standalone. You also have the option to order it less cylinder, or prepped for interchangeable cores: the 70 option is small format interchangeable core prep less core, and the 60 option is large format interchangeable core prep less core. Those two are how you order it when your locksmith is supplying the cores from your own stock.
4) What do I have to specify when ordering a Sargent 8205 mortise lock?
Four decisions. Lever design: A, B, E, F, J, L, P or W. Escutcheon trim: LE1, LS, LW1 or WT. Finish, from sixteen choices spanning 03 bright brass through 32D satin stainless and BSP black or WSP white suede powder coat. Then the cylinder and keying: standard cylinder, less cylinder, or 60/70 interchangeable core prep, paired with keyed different, keyed alike, or a specific key code you supply. If you pick less cylinder, select None on the keying.
5) What is the closest cross-brand equivalent to a Sargent 8205 office/entry mortise lock?
The Cal-Royal NM8050 is the nearest match by function and grade: it is a heavy duty Grade 1 Entrance/Office mortise lockset with an auxiliary deadlatch, sized for a 1-3/4 inch door. The Sargent 8205-ET is also a Grade 1 heavy duty mortise lock with an Office/Entry function and a single cylinder. The Cal-Royal is specified for 1-3/4 inch doors, so on thicker doors confirm the opening before ordering it. Both use the same office/entry pattern where the outside lever can be locked and released by key.
6) I need a classroom function instead of office/entry in a Grade 1 mortise lock. What should I order?
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 NM8070 is a heavy duty Grade 1 classroom mortise lockset with an auxiliary deadlatch, also for 1-3/4 inch doors. The Sargent 8205-ET carries the Office/Entry function, where the outside lever is locked and unlocked by key from the outside, so it will not give you the classroom behavior of keying the outside lever locked while the inside always exits free.
7) What is the difference between the Sargent 8205 and a storeroom mortise lock like the Accentra 8805FL?
Function. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever; a storeroom outside lever stays locked at all times and is retracted only by key. The Sargent 8205-ET is an Office/Entry function, single cylinder, so the outside lever can be left unlocked for business hours and keyed locked after. Cal-Royal's NM8080 is another Grade 1 storeroom mortise lockset, offered with an interchangeable core option, for 1-3/4 inch doors. Pick storeroom for a door that must never be left free, and office/entry for a door staff want open during the day.
8) Which mortise lock should I use if the opening needs to be released by an access control system?
For an electrified opening, the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation, and the Command Access ML190 is a heavy-duty motorized mortise lock in the ML190 Series with field selectable EL/EU operation on 24VDC and a storeroom function. Schlage's L9092EU with the 03A trim is a heavy duty mortise lock with an electric lock/unlock outside lever, keyed outside, request to exit, at 12/24VDC for 1-3/4 inch doors. The Sargent 8205-ET is the mechanical Office/Entry lock in the 8200 Series and is not itself an electronic unit.
9) What mortise lock should I specify for a behavioral health or ligature-resistant opening?
The TownSteel MRX-L-01 is a stainless steel Grade 1 heavy duty anti-ligature lever mortise lockset in passage function, and the MRX-A-01 is the same passage function with satin stainless steel ligature resistant arch trim, both for 1-3/4 inch doors. For a push/pull opening, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. The Sargent 8205-ET uses conventional lever trim, which is the right trim for a standard office door but not for a room where ligature resistance is on the spec.
10) How does the Schlage LE Series mobile-enabled mortise lock compare on grade to a Sargent 8205?
They sit at different ANSI/BHMA grades. The Schlage Electronics LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with push button and LED, covering privacy, office and apartment functions, rated 3 hours fire, for 1-3/4 inch doors. The Sargent 8205-ET is ANSI/BHMA A156.13 Series 1000 Grade 1 and UL 10C positive pressure fire rated up to 3 hours with NFPA 80 compliance. If the specification calls out Grade 1 mortise hardware, the LE Series will not satisfy it even though the fire rating matches.
11) Can I put a mortise lock on an aluminum storefront door with a narrow stile?
Not this one. The Sargent 8205-ET is a Grade 1 heavy duty mortise lock built for commercial swing doors with escutcheon or sectional trim. For aluminum storefront, the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad made for Adams Rite deadlatches, and the Dormakaba E-Plex 2066 is specified for wide stile doors. For an all-glass door, the Kaba Ilco BR Series is a glass door bottom rail lock. Match the lock to the door construction before you match it to the function.
12) Is the Sargent 8205-ET an electronic lock, and what is the 12 to 24VDC EcoFlex part about?
The 8205 itself is a mechanical, keyed mortise lock, not an electronic one. The 8200 Series platform does offer electromechanical functions that run on 12 to 24VDC using Sargent's EcoFlex power management, which cuts consumption on those functions by up to 96 percent, and the series spans 56 functions in total including electromechanical, security and monitoring variants. If what you actually need is a wired electric mortise lock for an access control system, look at the BEST 45HW wired electromechanical mortise lock, which also runs 12V/24V.
13) What is the difference between the escutcheon trim on the 8205-ET and a rose trim version?
Escutcheon trim is the tall plate that runs behind the lever and covers the cylinder and the lock face area as one piece; a rose is just a small round or shaped plate at the lever. The 8205-ET is the escutcheon configuration, with LE1, LS, LW1 and WT plate designs to choose from. Escutcheon is the usual pick when you are covering old prep or want a heavier look on an entrance door. Hager's 3800 Series shows the same split in one family: the 3810E is the escutcheon passage lock and the 3810S is the rose version.
14) Should I use a mortise lock like the Sargent 8205 or a cylindrical lockset on my commercial door?
A mortise lock goes into a rectangular pocket cut into the door edge and carries the latch, the deadlatch and the cylinder in one steel case, which is why it takes traffic a cylindrical lock will not. The trade off is the prep: the pocket has to be machined into the door, so a cylindrical retrofit is far simpler on an existing door that was never mortised. The 8205 is the mortise route. If the opening is bored rather than mortised, a cylindrical Grade 1 lock like the Schlage PC10 fits that prep instead.
15) I need Grade 1 office/entrance mortise locks but not the full Sargent price tier. What else is comparable?
The Cal-Royal NM8050 is the closest straight equivalent: heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch, listed for 1-3/4 inch doors. Where the Sargent 8205 pulls ahead is key system breadth and the 16 million cycle verification. If your building standard is Corbin Russwin or Schlage instead, the ML2003 (Grade 1, classroom function, 1-3/4 inch) and the Schlage L Series are the mortise families to match against, though those are different functions, not office/entry.
16) I'm standardizing lock functions across a school. Does the Sargent 8205 cover classroom and storeroom doors too?
The 8205 is office/entry only, so it is the wrong function for a classroom door where staff need to lock from inside, or a storeroom door that must stay locked at all times. Stay inside the 8200 Series for those, since it runs 56 functions on the same lock case, trim and key system, which is exactly how you standardize a facility. If you are cross-shopping, the Cal-Royal NM8070 is Grade 1 classroom and the NM8080 is Grade 1 storeroom with an interchangeable core option; TownSteel's FME-2000 is a Grade 1 classroom mortise with RFID if you want credentials on those doors.
17) Do I need to know the handing before I order the Sargent 8205?
Not for the lock body. Handing on the 8200 Series is field reversible, so the same lock covers a left or right hand door and you set it during install. That is useful on a multi-building order where you are not walking every opening first. The lever design you pick (A, B, E, F, J, L, P or W) is the same either way.
18) Is there a non-keyed mortise lock to use on interior doors that do not need to lock?
For a door with no locking requirement, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series with field reversible operation and a fire rating. Hager's 3810E is a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches thick, if escutcheon trim is what the rest of the openings use. The Sargent 8205-ET is keyed with a single cylinder, so it is the choice only where the door has to lock.
19) I need a privacy function on a restroom or bedroom door, not an entry lock. What mortise lock covers that?
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. The Sargent 8205-ET is an Office/Entry keyed function with a single cylinder, which is the wrong pattern for a restroom or bedroom door where you want inside-thumbturn privacy rather than key control.
20) Can I use a keypad mortise lock instead of a keyed one on an office door?
Yes, if you want to drop keys on that opening. The BEST 45HZ EZ Series is an electronic keypad mortise lock with a key override function, and the Accentra NTM623-NR is a Grade 1 nexTouch Generation 3 mortise lock with a capacitive touchscreen keypad, no deadbolt, with cylinder override. Dormakaba's E-Plex 2066 is an electronic pushbutton keyless mortise lock in the E-Plex 2000 Series for wide stile doors. The Sargent 8205-ET is the keyed mechanical route, single cylinder, and integrates with SARGENT Degree, Signature, KESO and XC key systems if you are keying the building rather than coding it.
21) Will a Baldwin 6301 mortise lock body substitute for a Sargent 8205?
They serve similar openings but are not interchangeable specifications. The Baldwin 6301 is an entry/apartment mortise lock body with a 2-1/2 inch backset, offered knob by knob or, as the 6301LS, lever by lever, for doors 1-3/4 inch and over. The Sargent 8205-ET is a Grade 1 heavy duty lever lock in the 8200 Series. The backset difference alone means the door prep will not line up, so a Baldwin is a choice made at the drawing stage, not a drop-in for an existing 8200 mortise pocket.
22) What looks like a mortise lock substitute but will not actually lock the door?
Dummy trim. The Schlage L0170 is a Grade 1 half dummy trim, non-keyed mortise lever lock for 1-3/4 inch doors, and Emtek's 3102 Memphis, 3104 Hamilton, 3106 Manhattan and 3019 Brisbane mortise entrance locksets are all dummy function. They mount a matching lever or knob on an inactive leaf and have no latch or cylinder behind them. The Sargent 8205-ET is a keyed Office/Entry mortise lock, so order dummy trim only for the leaf you never operate.
23) I want credentials on the door instead of keys but still need Grade 1 mortise hardware. What are the options?
The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors, and the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader, mobile enabled deadbolt with LED and Greenwich trim, right hand, carrying a 3 hour fire rating. Dormakaba's E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card lock in a back to back mortise configuration. The Sargent 8205-ET is the mechanical keyed counterpart and works with SARGENT key systems rather than credentials.
24) What is the difference between ordering a complete Sargent 8205 lockset and a bare mortise lock body like the BEST 45H?
Scope of supply. The BEST 45H is a heavy duty mortise lock body in public entrance function with field reversible operation, and the Baldwin 6310 is an entry/storeroom mortise lock body with a 2-1/2 inch backset for doors 1-3/8 inch and over; a lock body is the case that goes in the door pocket. The Sargent 8205-ET is ordered as a complete assembly with the escutcheon selected from LE1, LS, LW1 or WT, a lever from the A, B, E, F, J, L, P or W designs, and a finish from a range that includes 26D satin chrome and 32D satin stainless. Order a bare body when you are keeping existing trim and a complete lockset when you are replacing the whole opening.
25) Is a cylindrical lock an acceptable substitute for a mortise lock on a commercial door?
Only if the door prep supports it. The Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with rose, for 1-3/4 inch doors; a cylindrical lock uses a bored cross-bore prep. The Sargent 8205-ET is a mortise lock, which requires a rectangular pocket machined into the door edge. A door prepped for one will not accept the other without new machining or a filler, so confirm the existing prep before switching families.
26) I only need a deadbolt at that opening, not a latching entry lock. What mortise deadbolt is available?
The Kaba Ilco 185 Series is a mortise deadbolt with no handing, sold as a single pack, and the Alarm Lock DL4500 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 inches thick. The Sargent 8205-ET is a latching Office/Entry lockset with lever trim, so it is the wrong part where the design calls for a deadbolt alone above a separate pull or exit device.
27) I have a right hand reverse opening. Do I need to order a handed mortise lock?
It depends on the brand. Baldwin's 6310190RRLS is ordered as a right hand reverse lever by lever entry/storeroom mortise lock with a 2-1/2 inch backset, so handing is fixed at the order. The BEST 45H mortise lock body and the Falcon MA101 are field reversible, and the Sargent 8205-ET is field-reversible for handing as well, so a single part number covers either hand on the job.
28) I want an office function mortise lock without a key cylinder. What covers that?
The Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, with a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches thick. The Sargent 8205-ET is the keyed office/entry version with a single cylinder, and it can also be ordered less cylinder or with 60 large format or 70 small format interchangeable core prep if you supply your own cores. Choose the Hager where no key control is wanted at all and the Sargent where the opening belongs to a keyed system.
29) Can I get Sargent 8200 mortise locks in black to match the rest of the hardware?
Black is available as BSP, a black suede powder coat, with WSP white suede powder coat as the other painted option. For darker traditional looks there are also 10B dark oxidized satin bronze oil rubbed, 10BE, 10BL, and 20D dark statuary bronze lacquered. The high traffic commercial standards are 26D satin chrome and 32D satin stainless.
30) Where do I find the door prep dimensions for a Sargent 8200 mortise lock before I machine the doors?
Sargent publishes an installation template covering the 7800 and 8200 Series mortise locks with all sectional rose trims and escutcheon trims, and it is the document to cut from rather than measuring an existing lock. The full 7800/8200 mortise lock catalog carries the function list and trim details for the series.
31) Which mortise lock holds up outdoors or in a weather-exposed opening?
The Alarm Lock DL2700CR is a Trilogy T2 electronic mortise lock with a classroom function and weatherproof design, Grade 1, for doors 1-5/8 to 1-7/8 inches thick, and the DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes in the same classroom function and door thickness range. The Sargent 8205-ET is a Grade 1 heavy duty commercial mortise lock tested to 16 million cycles, and its finish list includes 32D satin stainless steel and BSP black suede powder coat for demanding environments.
32) Is a medium duty mortise latch enough for a commercial office door?
The Codelocks CL2255 is a medium duty electronic tubular mortise latch in the CL2000 Series with a brushed steel finish, which suits lighter traffic. The Sargent 8205-ET is a heavy duty Grade 1 commercial lock verified by UL at 16 million cycles, which is the duty level typically specified for high-traffic commercial office, healthcare and education openings. Match the duty level to the daily cycle count on that door.
33) What is a Grade 2 RFID mortise lockset alternative for a hospitality opening?
The Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, in the Saffire Series, and the Dormakaba PowerPlex P2066 is a mortise lock in the PowerPlex 2000 Series. Both put credentials at the door rather than keys. The Sargent 8205-ET is a Grade 1 mechanical Office/Entry mortise lock, so it is the choice where the specification holds to Grade 1 and to SARGENT keying rather than to guest credentials.
