Sargent 8245 LE1A 26D – Frequently Asked Questions

1) What does the dormitory/exit function on the Sargent 8245 mortise lock actually do?
The 8245 is a dormitory or exit function lock with a deadbolt. Outside is keyed by a single cylinder, and the inside lever always retracts both the latchbolt and the deadbolt for free egress. It suits dorm rooms, apartments and multi-tenant units where the occupant throws the deadbolt from inside but has to be able to get out in one motion.
2) Will the Sargent 8245-ET fit a 1-3/4 inch door with a 2-3/4 inch backset?
Yes. The 8245-ET is built for 1-3/4 inch door thickness with a 2-3/4 inch backset, which is the standard commercial mortise prep. Latchbolt throw is 3/4 inch, so it will engage a standard ANSI mortise strike at that backset.
3) Is the Sargent 8245 mortise lock fire rated for a labeled door?
It carries a UL 10C fire rating up to 3 hours and is certified to ANSI/BHMA A156.13 Series 1000 Operational Grade 1, so it can go on labeled openings up to a 3 hour rating.
4) What do I need to specify when ordering the Sargent 8245-ET?
Four choices. Cylinder: standard cylinder, less cylinder, 70 prep for small format interchangeable core less core, or 60 prep for large format IC less core. Keying: keyed different, keyed alike, or a specific key code (pick None if you ordered less cylinder). Then the escutcheon trim (LE1, LS, LW1 or WT), the lever design (A, B, E, F, J, L, P or W) and the finish.
5) Can the Sargent 8245 be keyed into our existing building master key system?
The 8245 lock body works with all Sargent key systems, including Degree, Signature, KESO and XC, in 6 pin or 7 pin cylinders. If your site already runs Sargent, it keys into that system. If you are using a third party core, order it with the 60 prep for large format interchangeable core or the 70 prep for small format, less core, and drop your own core in.
6) Will the Sargent 8245 work on a thicker door, say 2 inches?
No. The 8245-ET is specified for 1-3/4 inch doors. If your leaf is thicker, the Hager 3800 Series mortise locks cover 1-3/4 to 2-1/2 inches, and the Baldwin 6301 mortise body is listed for 1-3/4 inch and over on a 2-1/2 inch backset.
7) Which mortise lock should I use for a classroom door instead of the Sargent 8245-ET?
The 8245-ET is built for dormitory/exit openings with a deadbolt. For classroom function, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch, and the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with an ANSI strike for 1-3/4 inch doors.
8) What is a comparable Grade 1 mortise lock to the Sargent 8245-ET if the opening needs storeroom function instead of dormitory?
The Sargent 8245-ET is a Grade 1 mortise lock with dormitory/exit function and a deadbolt. For a storeroom opening, the Accentra 8805FL is a Grade 1 mortise lock with storeroom function from the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. Storeroom keeps the outside lever locked at all times with key access, where the 8245-ET dormitory function adds a deadbolt the occupant controls from inside.
9) What looks like a substitute for the Sargent 8245-ET but will not actually secure the door?
Several mortise-family items carry similar lever and escutcheon looks without a working latch or deadbolt. The Schlage L0170 is a Grade 1 half dummy trim, non-keyed, for 1-3/4 inch doors, and the Emtek 3102 Memphis and 3104 Hamilton mortise entrance locksets are dummy function. Passage units such as the Falcon MA101 Grade 1 heavy duty mortise passage lock and the Schlage PM010 Grade 1 passage latch mortise lock latch but do not lock. The Sargent 8245-ET is a keyed single cylinder dormitory/exit lock with a deadbolt.
10) For an apartment entry door, how does the Sargent 8245-ET compare to the Baldwin 6301?
The Sargent 8245-ET is a Grade 1 heavy duty commercial mortise lock with dormitory/exit function, a deadbolt, and a 2-3/4 inch backset for 1-3/4 inch doors, offered with lever trim in escutcheon styles LE1, LS, LW1 and WT. The Baldwin 6301LS is an entry/apartment mortise lock body with a 2-1/2 inch backset and lever by lever trim for doors 1-3/4 inch and over; a knob by knob version is the 6301. The backset difference matters because the door prep is not interchangeable.
11) Do I have to order the Sargent 8245 handed?
No. The 8245 lock body is field reversible, so one lock covers left and right hand openings. That is useful if you are stocking spares for a building rather than buying door by door.
12) Is this Sargent 8245 an electrified lock?
No. This one is a mechanical, keyed mortise lock, not electronic. Sargent does build electromechanical versions of the 8200 body that run 12 to 24VDC with EcoFlex, but if you need access control at the door, look at an electronic mortise lock such as the BEST 45HW wired electromechanical mortise lock or the Schlage L9092EU with 12/24VDC and request to exit.
13) How durable is the Sargent 8245 for a high traffic dorm or apartment corridor?
It is a Grade 1 heavy duty lock, and Sargent's UL Cycle Above and Beyond test on the 8200 body was completed at 16 million cycles (Verification ID V584148). The case is a Cycolac rust-proof cement case, which is what gives it its vandal and strength performance in abused openings.
14) Does the Sargent 8245-ET come with escutcheon trim or do I buy that separately?
Trim is part of the order. The ET designation means escutcheon trim, and you pick the escutcheon style (LE1, LS, LW1 or WT) along with the lever design and finish when you order. Templates for the 7800 and 8200 series with sectional rose and escutcheon trims are published by Sargent for door prep.
15) If I only need an office or entrance function mortise lock and not a deadbolt, what can I use instead of the Sargent 8245-ET?
The 8245-ET carries a deadbolt with its dormitory/exit function. If the opening only needs an office or entrance lock, the Cal-Royal NM8050 is a Grade 1 heavy duty office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches thick.
16) Is there an electronic or keypad mortise lock I can use in place of the Sargent 8245-ET?
The 8245-ET is a mechanical, non-electronic mortise lock. For credential or code access on a mortise prep, the Accentra NTM623-NR nexTouch Generation 3 uses a capacitive touchscreen keypad with cylinder override and no deadbolt, 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 classroom mortise lockset with RFID for 1-3/4 inch doors.
17) I need an electrified mortise lock for access control instead of the Sargent 8245-ET mechanical version - what are the options?
The 8245-ET as configured is a mechanical keyed mortise lock. For an electrified opening, 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 fail safe or fail secure operation on 24VDC in storeroom function, and the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock with request to exit, keyed outside, at 12/24VDC for 1-3/4 inch doors.
18) Is there a Grade 1 mortise lock for a behavioral health room where the Sargent 8245-ET lever would be a ligature risk?
The 8245-ET uses lever trim, which is not suited to anti-ligature openings. The TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel with passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with ligature resistant arch trim, 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.
19) What is the difference between the Sargent 8245-ET and the BEST 45H public entrance mortise lock?
Both are heavy duty mortise locks with field reversible handing. The Sargent 8245-ET is Grade 1 with dormitory/exit function, a deadbolt, and a keyed single cylinder, sold with lever trim and escutcheon. The BEST 45HCAC is a heavy duty mortise lock body in public entrance function from the 45H series, where the outside lever is locked and unlocked by key rather than by an occupant-thrown deadbolt. BEST also offers the 45HCA lockbody in intruder function.
20) Will an Alarm Lock Trilogy mortise lock fit the same door as the Sargent 8245-ET?
Check the door thickness before you assume it does. The Sargent 8245-ET is built for 1-3/4 inch door thickness with a 2-3/4 inch backset. The Alarm Lock DL3500CR and DL2700CR are Grade 1 electronic mortise locks in classroom function listed for 1-5/8 to 1-7/8 inch doors, and the DL4500 is a Grade 1 electronic mortise deadbolt with privacy keypad over the same 1-5/8 to 1-7/8 inch range. Those are keypad units in different functions, so they are a replacement strategy rather than a drop-in for a dormitory lock with lever trim.
21) For a multifamily building moving to mobile credentials, what mortise lock replaces the Sargent 8245-ET?
The 8245-ET is a mechanical keyed lock in dormitory/exit function. For mobile and card access on apartment doors, the Schlage LE Series LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with push button and LED covering privacy, office and apartment functions, with a 3 hour fire rating for 1-3/4 inch doors, and the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile-enabled deadbolt, 3 hour fire rating, right hand with Greenwich trim. Note the LEMD is handed where the Sargent 8245-ET is field reversible.
22) What finishes does the Sargent 8200 Series escutcheon trim come in?
Sixteen: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized bronze, 10BE, 10BL, 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 choices when matching existing commercial openings.
