Sargent 8245 EA 26D – Frequently Asked Questions

1) What does the dormitory/exit function on the Sargent 8245 mortise lock actually do?
The 8245 is Sargent's dormitory/exit function in the 8200 Series. It is a single cylinder lock with a deadbolt, so the deadbolt is thrown by key from the outside and by an inside turn, and the inside lever always retracts both bolts for free egress. That combination is why it lands in apartment and dormitory openings, where a resident needs to secure the unit from inside but nobody can be locked in.
2) Will the Sargent 8245 fit a 1-3/4 inch commercial door?
Yes. The 8245 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 doors are thinner interior slabs or oversized, this is not the lock to spec.
3) Will the Sargent 8245 latch into my existing ANSI mortise strike?
The latchbolt throws 3/4 inch and the lock uses the standard 2-3/4 inch backset mortise prep, so it drops into an opening already cut for a commercial mortise lock and picks up a standard ANSI strike. What you do have to confirm is that the frame is also prepped for the deadbolt, since the 8245 carries one and a latch-only strike will not accept it.
4) Does the Sargent 8245 come with a cylinder, and can I put it on my existing master key system?
Cylinder is a choice you make when ordering. You can take it with a standard cylinder, less cylinder, or prepped for an interchangeable core with the core left out, either small format (70) or large format (60). Keying options are keyed different, keyed alike, or to a specific key code you supply. The lock works with all Sargent key systems, including Degree, Signature, KESO and XC, so it can be brought onto an existing Sargent masterkey system.
5) Is the Sargent 8245 tough enough for a high traffic dormitory or apartment entrance?
It is a Grade 1 heavy duty commercial lock, and Sargent completed UL Cycle Above and Beyond testing at 16 million cycles (Verification ID V584148). Grade 1 is the highest ANSI/BHMA durability tier, which is what you want on a resident entry door getting dozens of operations a day.
6) What is the closest Grade 1 mortise equivalent to the Sargent 8245 for a dormitory or apartment entry door from another manufacturer?
The Sargent 8245 is a Grade 1 single cylinder mortise lock with deadbolt in dormitory/exit function. The closest peer for an apartment entry opening is the Cal-Royal NM8050, a heavy duty Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, or the Baldwin 6301LS, an entry/apartment lever by lever mortise lock body with a 2-1/2 inch backset for doors 1-3/4 inch and over. Note the backset difference: the 8245 uses a 2-3/4 inch backset, so the Baldwin 6301LS is not a drop-in for a door already prepped for the Sargent.
7) If I do not need the deadbolt, what mortise lock should I use instead of the Sargent 8245?
The 8245 is a single cylinder mortise lock with a deadbolt in addition to the latchbolt. If the opening only needs a keyed latch, the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option, and the Accentra 8805FL is a Grade 1 storeroom mortise lock with the Arcadia lever. Both are latch-only storeroom function, so the outside lever stays locked and the key retracts the latch, with no separate deadbolt to throw.
8) What is the difference between the Sargent 8245 and the Corbin Russwin ML2003 for a school door?
The Sargent 8245 is dormitory/exit function, which pairs a keyed latch with a deadbolt for residential-style entry openings. The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, where the key controls the outside lever rather than a deadbolt. For classrooms, the Cal-Royal NM8070 is also a Grade 1 classroom mortise lockset with auxiliary deadlatch. Choose by function: dorm rooms and apartments take the 8245, instruction spaces take a classroom function body.
9) I want keypad access on dorm rooms instead of keys - what replaces the Sargent 8245 mechanical mortise lock?
The 8245 is a mechanical keyed mortise lock, not electronic. For credential-based access on the same style of opening, the Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with 300 user codes in classroom function for 1-5/8 to 1-7/8 inch doors, the Alarm Lock DL4500DB is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad, and the Schlage CO-100-MS-40-KP is a Grade 1 standalone electronic mortise lock in privacy function with a keypad reader for 1-3/4 inch doors. The DL4500DB is the deadbolt-based option if the deadbolt is the reason you were specifying the 8245.
10) What mortise lock should I use instead of the Sargent 8245 for a card or mobile credential system?
The 8245 is a mechanical lock keyed to Sargent key systems. For RFID or mobile credentials, the TownSteel FME-2000 is a Grade 1 heavy duty mortise lockset with RFID technology in classroom function for 1-3/4 inch doors, the Dormakaba E-Plex 5086 is a Grade 1 pushbutton and card mortise lock in entry/egress configuration, and the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and mobile-enabled deadbolt, right hand, with a 3 hour fire rating. The LEMD is the one that keeps a deadbolt in the package.
11) Will a Sargent 8245 work on an aluminum storefront door, or do I need a different lock?
The Sargent 8245 is built for 1-3/4 inch doors with a 2-3/4 inch backset and standard commercial mortise prep, which is a hollow metal and wood door profile rather than a narrow aluminum stile. For storefront, 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 a wide stile electronic pushbutton keyless mortise lock, and the Kaba Ilco BR series is a glass door bottom rail lock. Match the lock to the stile width before ordering.
12) Do I have to order the Sargent 8245 handed?
No. Handing is field reversible on the 8245, so one lock covers left and right hand openings and you can change it on site. For a property manager or a shop carrying stock across a building, that cuts what you have to keep on the shelf.
13) What lever and rose choices do I get on the Sargent 8245, and will they match the other doors in my building?
Lever trim comes in eight designs (A, B, E, F, J, L, P and W) on four rose sizes: E rose at 3-1/16 inches, L rose at 3-1/2 inches, LN rose at 2 inches and O rose at 2-3/4 inches. Sixteen finishes are offered, from 26D satin chrome and 32D satin stainless through 10B oil rubbed bronze, 04 satin brass, 15 satin nickel and black or white suede powder coat. Match the existing lever letter, rose letter and finish code off one of your current 8200 Series locks and the new opening will look identical.
14) Is the Sargent 8245 an electronic lock?
No, the 8245 as configured here is a mechanical, key operated mortise lock. The 8200 Series does offer electromechanical versions running 12 to 24VDC with EcoFlex technology, but if you need access control at the door you would spec one of those rather than the 8245.
15) I need a mortise lock with a deadbolt but for a bathroom or privacy application, not an apartment entry. What else is there?
The 8245 is keyed with a single cylinder for resident entry use, so it is the wrong function for a privacy door. For a Grade 1 privacy mortise lock with a deadbolt, look at the Cal-Royal NM8440, which is listed for 1-3/4 inch doors. If you need keyed storeroom instead, the Cal-Royal NM8080 or the Accentra 8805FL are Grade 1 storeroom mortise locks.
16) My doors are 1-5/8 to 1-7/8 inches thick. Can I still use the Sargent 8245?
No. The 8245 is specified for 1-3/4 inch doors. If your openings run 1-5/8 to 1-7/8 inches, the Alarm Lock Trilogy mortise locks (DL2700CR and DL3500CR, both Grade 1 classroom function) cover that range, though they are electronic keypad locks rather than a mechanical dormitory function.
17) I want to standardize a multi-family building on one mortise lock but some doors need classroom or passage function. Can I stay in one line?
Yes. The 8245 is one of 56 functions in the Sargent 8200 Series, covering mechanical, electromechanical, security and monitoring configurations. Spec the same lever, rose and finish across the building and change only the function number per opening, so every door looks the same and the key system stays common.
18) If I order the Sargent 8245 less cylinder, what do I still need to buy?
Less cylinder means the lock body and trim ship without a cylinder, so you supply a mortise cylinder yourself, typically to match an existing Sargent keyway. If you pick the 70 or 60 prep instead, the lock is machined for a small format or large format interchangeable core and you add the core separately. Keying should be set to None when you take the less cylinder route.
19) Is the Schlage L0170 or an Emtek 3102 a substitute for the Sargent 8245?
No. The Sargent 8245 is a keyed single cylinder mortise lock with a deadbolt. The Schlage L0170 is half dummy trim, a Grade 1 non-keyed mortise dummy for 1-3/4 inch doors, and the Emtek 3102 Memphis mortise entrance lockset is also dummy function. Dummy trim has no latch and no lockable mechanism - it is pull-only hardware for an inactive leaf. They match the mortise look but will not secure an opening.
20) What is the difference between the Sargent 8245 and a privacy mortise lock like the Cal-Royal NM8440 or Hager 3840S?
The Sargent 8245 is keyed from the outside and used for dormitory and apartment entries. 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 1-3/4 to 2 inch doors - both are bed/bath privacy, locked by a thumbturn from inside with no keyed outside cylinder. Use privacy for restrooms and bedrooms inside a unit, and the 8245 at the unit entry door.
21) We need an electrified mortise lock on the same doors as our Sargent 8245 openings - what are the options?
The Sargent 8200 series is offered in electromechanical versions operating from 12 to 24VDC. Comparable electrified mortise bodies include the BEST 45HW heavy duty wired electromechanical mortise lock with 12V/24V operation, the Command Access ML190 motorized mortise lock with field selectable electrically locked or unlocked operation on 24VDC in storeroom function, and the Schlage L9092EU 03A electric lock/unlock outside lever mortise lock, keyed outside with request-to-exit, 12/24VDC, for 1-3/4 inch doors. All three run on the same voltage band, so an existing 12 to 24VDC supply carries over.
22) I only need a lock body to swap into an existing mortise pocket, not a complete lockset like the Sargent 8245 - what should I look at?
The Sargent 8245 ships as a complete lockset with lever and rose trim, offered in A, B, E, F, J, L, P and W levers and E, L, LN and O roses. If you are reusing existing trim, the BEST 45H series is a heavy duty mortise lock body in public entrance function with field reversible operation, and the BEST 45HCA is a heavy duty mortise lockbody with intruder function. Confirm the existing trim's spindle and cylinder prep matches the body before ordering.
23) For a behavioral health or anti-ligature opening, is the Sargent 8245 appropriate or is there a better mortise lock?
The Sargent 8245 uses conventional lever trim with rose, which is not designed for ligature resistance. For those 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 ligature resistant arch trim version in satin stainless, 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. All three are passage function, so pair them with separate security hardware if the opening also has to lock.
24) What do I use instead of the Sargent 8245 on a corridor or closet door that does not need to lock?
The Sargent 8245 is a keyed lock with a deadbolt, which is more hardware than an unlocked opening needs. For those, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, the Hager 3810S is a Grade 1 passage mortise lock with rose and a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors, and the Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors. The Hager 3810S shares the 2-3/4 inch backset the 8245 uses.
25) Can I use the Sargent 8245 on a 2 inch thick door, or is there a mortise lock with a wider thickness range?
The Sargent 8245 is specified for 1-3/4 inch door thickness. If the door is thicker, the Hager 3810E passage mortise lock covers 1-3/4 to 2-1/2 inch doors with a 2-3/4 inch backset, as does the Hager 3850E office mortise lock with lever and escutcheon, and the Baldwin 6310 entry/storeroom mortise body covers 1-3/8 inch and over. Those are different functions than dormitory/exit, so confirm the function suits the opening before substituting on thickness alone.
26) Is a deadbolt-only mortise unit like the Kaba Ilco 185 the same thing as the Sargent 8245?
No. The Sargent 8245 combines a keyed latchbolt with lever trim and a deadbolt in one mortise body, so one lock handles both day operation and the secondary lock. The Kaba Ilco 185 series is a deadbolt function mortise lock with no handing, and the Alarm Lock DL4500DB is an electronic mortise deadbolt. Those are deadbolt-only bodies and need a separate latch or passage set on the door to operate it day to day.
