Sargent 8225 LE1A 26D – Frequently Asked Questions

1) What does the dormitory/exit function do on the Sargent 8225 mortise lock?
The 8225 is a dormitory or exit function lock: the outside lever is locked or unlocked by key, and the deadbolt is thrown or retracted by the key outside or by the inside turn. Turning the inside lever retracts both the latchbolt and the deadbolt at once, so anyone inside always gets out in a single motion. That combination is why it shows up on apartment, dorm and multi-tenant unit doors where a tenant wants a deadbolt but the opening still has to allow free egress.
2) Will the Sargent 8225-ET fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
That is exactly its prep. The 8225-ET is built for 1-3/4 inch door thickness with a 2-3/4 inch backset, which is the standard commercial mortise prep. If your existing pocket is cut for a 2-3/4 inch backset mortise body, the lock drops into it. Doors thicker than 1-3/4 inch need a different arrangement, so verify the leaf before you cut.
3) Will the Sargent 8225 latch into the strike that's already in my frame?
The 8225 throws a 3/4 inch latchbolt, which is the standard commercial mortise latch projection, so it will engage a correctly aligned ANSI mortise strike already in the frame. What matters more on a retrofit is the deadbolt: this is a deadbolt function lock, so the frame needs a strike with the deadbolt pocket as well as the latch cutout. A latch-only strike from a non-deadbolt mortise lock will have to be swapped.
4) Is the Sargent 8225 mortise lock fire rated for a 3 hour opening?
Yes. The 8225 is UL 10C fire rated up to 3 hours, carries UL-cUL listing and complies with NFPA 80, so it can go on a labeled opening up to a 3 hour rating. It is also ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and ADA compliant, which covers the usual institutional spec language for lever operation and durability.
5) What do I have to specify when ordering the Sargent 8225-ET?
Four choices plus keying. Escutcheon trim is LE1, LS, LW1 or WT. Lever design is A, B, E, F, J, L, P or W. Finish runs 16 options, from 03 bright brass and 04 satin brass through 10B oil rubbed bronze, 26D satin chrome, 32D satin stainless, and BSP black or WSP white suede powder coat. For the cylinder you pick standard cylinder, less cylinder, 70 for small format interchangeable core prep less core, or 60 for large format IC prep less core. Then keying: keyed different, keyed alike, or a specific key code (choose none if you ordered less cylinder).
6) Can I order the Sargent 8225 with an interchangeable core prep so I can use my own cores?
Yes. Besides a standard cylinder or less cylinder, the 8225 can be ordered with the 70 prep for small format interchangeable core or the 60 prep for large format interchangeable core, both supplied less core. Facilities already running SFIC or LFIC keying pick the matching prep and drop their own cores in, which keeps the opening on the existing masterkey system.
7) Can the Sargent 8225 be keyed into our existing Sargent master key system?
It works with all Sargent key systems, including Degree, Signature, KESO and XC, so an 8225 can be brought onto the same masterkey hierarchy as the rest of a Sargent-equipped building. Order keyed alike if a run of doors should share one key, keyed different for individual units, or supply the key code directly if you are matching an existing system.
8) What is a comparable Grade 1 mortise lock if the opening needs storeroom function instead of dormitory/exit?
The Sargent 8225-ET is a Grade 1 mortise lock built for dormitory/exit function with a single-cylinder deadbolt. For a storeroom opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. Storeroom function keeps the outside lever locked at all times and is keyed entry only, so choose it where residents should not be able to leave the door unlocked.
9) What is the electronic equivalent if I want keypad or credential access instead of a keyed dormitory mortise lock?
The Sargent 8225-ET is a mechanical, non-electronic keyed mortise lock. For credential access on the same mortise prep, the Accentra NTM623-NR nexTouch Generation 3 uses a capacitive touchscreen keypad with cylinder override and no deadbolt, the Schlage CO-100-MS is a Grade 1 standalone electronic mortise lock with keypad reader in privacy function for 1-3/4 inch doors, and the TownSteel FME-2000 is a Grade 1 heavy-duty RFID mortise lockset in classroom function for 1-3/4 inch doors. Note the nexTouch has no deadbolt, so it does not replicate the 8225's deadbolt.
10) Which mortise locks look like substitutes for the Sargent 8225-ET but will not secure the door?
Several mortise-trim products share the look but do not lock. The Schlage L0170 is a half dummy trim, non-keyed Grade 1 heavy duty for 1-3/4 inch doors, and the Falcon MESC600DT is a dummy escutcheon lever trim for M9900 Series exit devices. Emtek's 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are also dummy function. The Schlage PM010 and Falcon MA101 are Grade 1 passage mortise locks, which latch but are not keyed. The Sargent 8225-ET is keyed with a deadbolt, so none of these are functional replacements.
11) If I need the mortise lock tied into access control or a fail-safe/fail-secure circuit, what replaces the 8225-ET?
The Sargent 8225-ET is a non-electronic mechanical mortise lock. For electrified openings, the BEST 45HW is a heavy-duty wired electromechanical mortise lock with 12V/24V operation, the Command Access ML190 is a heavy-duty motorized mortise lock with field-selectable EL/EU operation on 24VDC in storeroom function, and the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, 12/24VDC, for 1-3/4 inch doors. Field-selectable EL/EU on the Command Access unit lets one device cover either fail-safe or fail-secure.
12) Is the Schlage LE Series mortise lock a like-for-like swap for the Sargent 8225-ET on an apartment door?
Not on grade. The Sargent 8225-ET is an ANSI/BHMA Grade 1 mortise lock UL 10C fire rated up to 3 hours. The Schlage LEBMB-ADD mobile-enabled mortise lock covers privacy, office and apartment functions with a 3-hour fire rating for 1-3/4 inch doors, but it is listed as Grade 2. If the specification calls for Grade 1, the Sargent 8225-ET or the Grade 1 Schlage LEMD-GRW ENGAGE mortise lock meets it.
13) Is the Sargent 8225-ET tough enough for a high traffic dorm or apartment entry?
It is rated heavy duty and completed the UL Cycle Above and Beyond test at 16 million cycles (Verification ID V584148), well past what Grade 1 alone requires. On a student housing or multi-family unit door taking constant use, that cycle number and the Grade 1 operational rating are the reason facilities standardize on the 8200 body rather than a cylindrical lockset.
14) Is the Sargent 8225-ET an electronic lock, or purely mechanical?
The 8225-ET is a mechanical mortise lock, key and lever operated, with no power or credential reader. If the opening needs access control, the mortise alternatives are electrified or standalone units such as the BEST 45HW wired electromechanical mortise lock running 12V/24V, the Command Access ML190 motorized mortise lock with field selectable EL/EU on 24VDC, or a standalone keypad unit like the BEST 45HZ EZ Series with key override.
15) What's the difference between the 8225 dormitory/exit lock and a storeroom or classroom mortise lock?
Function, not build. The 8225 adds a deadbolt and gives the occupant inside control: key or inside turn throws the bolt, inside lever retracts everything for egress. A storeroom lock, like the Accentra 8805FL or the Cal-Royal NM8080, keeps the outside lever locked at all times with no deadbolt and no occupant control. A classroom function, such as the Corbin Russwin ML2003 or Cal-Royal NM8070, is key-locked from the outside only. Pick the 8225 for residential-style unit doors; pick storeroom or classroom for a facility door nobody sleeps behind.
16) What other Grade 1 mortise locks with a deadbolt could I use instead of the Sargent 8225?
For a mechanical Grade 1 mortise lock with a deadbolt on a 1-3/4 inch door, the Cal-Royal NM8440 is a privacy function with deadbolt, though privacy is not the same as a keyed dormitory function. On the residential-style side, the Baldwin 6301 entry/apartment mortise body is offered in knob-by-knob and lever-by-lever for doors 1-3/4 inch and over. If the requirement is keyed dormitory function with the full Sargent keyway range and a 3 hour fire label, the 8225 is the direct answer and the substitutes each change something.
17) Does the Sargent 8225-ET come with escutcheon trim or do I order the plates separately?
The ET designation means it ships as an escutcheon trim lockset, so the long plates come with it. You select the escutcheon style (LE1, LS, LW1 or WT) and lever design together with the finish, and all of it arrives matched. If the rest of your doors use sectional rose trim instead of escutcheons, the plate footprint on the door face will not match, which matters visually on a corridor of existing openings.
18) Can the Sargent 8225 be used on an exterior door exposed to weather and wind loads?
It carries the storm and impact test certifications specifiers ask for on exterior openings: ASTM E330 structural load, E1996 and E1886 impact and cyclic pressure, and TAS 201, 202 and 203, the Miami-Dade protocols. Combined with the 3 hour UL 10C rating, that makes it usable on exterior unit entries in hurricane zone work where the door assembly itself is rated.
19) I only need a deadbolt on the door, not a full lever lockset - what should I order?
The Sargent 8225-ET combines lever trim with a heavy-duty single-cylinder deadbolt in one Grade 1 mortise body. If the opening needs deadbolt only, the Kaba Ilco 185 Series is a deadbolt-function mortise lock supplied with no handing, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and privacy keypad for doors 1-5/8 to 1-7/8 inch. Neither provides the latching lever operation of the 8225-ET, so a separate latch is needed for normal passage.
20) What is the alternative if the door is thicker than 1-3/4 inch?
The Sargent 8225-ET is specified for 1-3/4 inch door thickness. For a thicker leaf, Hager's 3800 Series covers 1-3/4 inch to 2-1/2 inch: the 3810E passage with escutcheon and 2-3/4 inch backset, the 3810S passage with rose, and the 3850E office function with lever and escutcheon, non-keyed, on a 2-3/4 inch backset. Baldwin's 6301 entrance/apartment body is listed for 1-3/4 inch and over on a 2-1/2 inch backset. Match function carefully, as the Hager options listed are passage and office rather than dormitory/exit.
21) For a behavioral health or ligature-resistant opening, what mortise lock should be used instead?
The Sargent 8225-ET uses conventional lever trim in eight lever designs, which is not suited to anti-ligature applications. TownSteel's MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function with satin stainless ligature-resistant arch trim. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. All three are passage function, so they do not key or deadbolt.
22) Can I use a cylindrical lock instead of the Sargent 8225-ET mortise lock?
No - the Sargent 8225-ET is a mortise lock, which requires a routed mortise pocket in the door edge rather than a bored hole. Schlage's PC10 is a Grade 1 passage cylindrical lock, non-keyed with rose, for 1-3/4 inch doors, and it is prepped differently, so it is not a drop-in for a mortise pocket. If the door is already mortised, stay with a mortise body such as the 8225-ET or the Cal-Royal NM8050 Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors.
23) I just need a replacement mortise lock body, not a complete trimmed lockset - what are my options?
The Sargent 8225-ET ships as a complete assembly with escutcheon trim in LE1, LS, LW1 or WT and a choice of eight lever designs. If the existing trim is being reused, the BEST 45HCA heavy duty mortise lock body is available in public entrance function with field reversible operation, and the 45HCAINL is a heavy duty mortise lockbody with intruder function. Baldwin's 6310 is an entrance/storeroom mortise lock body on a 2-1/2 inch backset for doors 1-3/8 inch and over.
24) For a privacy bath or bedroom door in the same building, what mortise lock pairs with the Sargent 8225-ET?
The Sargent 8225-ET is a keyed dormitory/exit lock and is not a privacy function. For interior privacy openings, 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 3800 Series Grade 1 privacy mortise lock with 2-3/4 inch backset for doors 1-3/4 inch to 2 inch. Both match the 8225-ET's 2-3/4 inch backset family for consistent door prep on a standardized project.
25) What mortise options exist for an intruder or lockdown-capable classroom instead of dormitory function?
The Sargent 8225-ET is dormitory/exit function, which locks the outside lever by key and does not provide inside lockdown. For lockdown, the BEST 45HCAINL is a heavy duty mortise lockbody with intruder function, and the TownSteel FME-4000 is an electronic intruder classroom mortise lockset with RFID technology, Grade 1 heavy duty for 1-3/4 inch doors. Intruder function allows securing the door from the inside without opening it.
26) Are there Grade 1 mortise locks with battery or keyless credential management for multifamily turnover instead of rekeying cylinders?
The Sargent 8225-ET is keyed and integrates with Sargent Degree, Signature, KESO and XC key systems, so turnover means rekeying or swapping cores. Keyless Grade 1 alternatives include the Dormakaba E-Plex E5086 entry/egress electronic pushbutton and card back-to-back mortise lock, the Alarm Lock DL3500CR Grade 1 Trilogy with 300 user codes for doors 1-5/8 to 1-7/8 inch, and the Schlage LEMD-GRW Grade 1 ENGAGE wireless mortise lock with 125kHz proximity reader and mobile-enabled deadbolt with LED, 3-hour fire rating, right hand. Codes or credentials are changed in software rather than at the cylinder.
27) Which mortise lock is comparable to the Sargent 8225-ET for a hotel or apartment door where power wiring is not available?
The Sargent 8225-ET is a mechanical Grade 1 apartment and dormitory mortise lock needing no power at all. If electronic credentials are wanted without wiring, the Dormakaba PowerPlex P2066 Series mortise lock and the Dormakaba Saffire LX-I-M002 electronic RFID mortise lockset with BLE mobile access, BHMA Grade 2, are self-contained at the door. The Saffire is Grade 2, so verify the specification if Grade 1 is required.
28) Is there an installation template for prepping the door for a Sargent 8200 mortise lock?
Yes. Sargent publishes a 7800/8200 Series mortise lock template covering all sectional rose trims and escutcheon trims, and it is the sheet to use for laying out the mortise pocket, the cylinder and turn holes, and the trim through-bolts. The 7800/8200 Mortise Lock Catalog covers the full function and trim range if you are specifying across several door types at once.
29) Is there a medium duty mortise alternative for a low-traffic interior door?
The Sargent 8225-ET is a heavy duty Grade 1 mortise lock tested to 16 million cycles, which suits high-traffic commercial and multifamily corridors. For a light-traffic interior door, the Codelocks CL2255 is a medium duty electronic tubular mortise latch in the CL2000 Series with a brushed steel finish. It is a latch only, so it does not provide the keyed deadbolt security of the 8225-ET.
