Sargent 8241 LE1A 26D – Frequently Asked Questions

1) What does the Sargent 8241 classroom security intruder deadbolt function actually do?
The 8241 is a double cylinder classroom security function: a key is required on both the outside and the inside. The inside cylinder throws the deadbolt so a teacher can lock the door down from inside the room without stepping into the corridor, and the outside cylinder gives staff and responders key access. That is the difference between this and a standard classroom lock, where only the corridor side is keyed.
2) How many cylinders do I need to order for a Sargent 8241 classroom security lock?
Two. It is a double cylinder function, keyed inside and out, so both openings need a cylinder. On the order you pick Standard Cylinder, Less Cylinder, 70 for small format interchangeable core prep less core, or 60 for large format interchangeable core prep less core, then set keying as KD keyed different, KA keyed alike, or to a specific key code. If you go less cylinder or IC prep less core, select None for keying and supply the cores yourself.
3) Can the Sargent 8241 be keyed into our existing school master key system?
It works with all SARGENT key systems, including Degree, Signature, KESO and XC, so it can be brought into an existing Sargent masterkey system. If your facility runs a different manufacturer's keyway, order it with small format or large format interchangeable core prep less core (the 70 or 60 option) and install your own cores.
4) Is the Sargent 8241 mortise lock approved for a fire rated classroom door?
The 8200 Series mortise lock supports UL 10C positive pressure fire rated applications up to 3 hours with NFPA 80 compliance, so it suits labeled classroom and corridor doors. It is also ADA compliant and the parent lock is ASTM E330 certified and Florida Building Code approved.
5) If I do not need the intruder deadbolt, what simpler classroom mortise lock can I use instead of the Sargent 8241-ET?
For a standard classroom function without the inside intruder deadbolt, the Cal-Royal NM8070 is a Grade 1 heavy duty classroom mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset in the ML2000 Series, also for 1-3/4 inch doors. Both are keyed classroom locks; neither carries the inside-keyed deadbolt that the Sargent 8241-ET provides as a double cylinder classroom security intruder deadbolt function.
6) What is the closest mechanical alternative to the Sargent 8241-ET classroom security intruder deadbolt lock from another brand?
The Marks USA LA318GJ is the closest mechanical match: it is a Grade 1 classroom security indicator mortise lockset with escutcheon trim, supplied with an ANSI strike, and rated for 1-3/4 inch doors. Like the Sargent 8241-ET, it is a non-electronic Grade 1 mortise lock with classroom security function and escutcheon trim rather than sectional roses. The Sargent side differs in keying breadth, since the 8241-ET works with all SARGENT key systems including Degree, Signature, KESO and XC.
7) Is there an electronic version of the classroom intruder function if I want to move off mechanical keys instead of the Sargent 8241-ET?
Yes. The TownSteel FME-4000 Series is an electronic intruder classroom mortise lockset with RFID technology, Grade 1 heavy duty, for 1-3/4 inch doors, and the FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID for the same door thickness. The Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with classroom function and 300 user codes for 1-5/8 to 1-7/8 inch doors. The Sargent 8241-ET is a non-electronic mortise lock, so credentials stay mechanical and master keyed through the SARGENT key systems.
8) My door is 1-5/8 inch thick. Can I still use the Sargent 8241-ET classroom security lock?
The Sargent 8241-ET escutcheon trim is specified for 1-3/4 inch door thickness. For thinner doors in the 1-5/8 to 1-7/8 inch range, the Alarm Lock Trilogy DL2700CR classroom function mortise lock and the Grade 1 DL3500CR classroom mortise lock both list that range, and the DL4500 Series electronic mortise deadbolt covers it as well. Those are electronic keypad locks, where the 8241-ET is a mechanical keyed mortise lock.
9) What is the difference between the LE1, LS, LW1 and WT escutcheon options on the Sargent 8241-ET?
Those four codes are the escutcheon plate styles the 8241-ET is offered in. You pick one escutcheon style, one of eight lever designs (A, B, E, F, J, L, P or W), and a finish. If you are matching other openings in the building, match the escutcheon code and lever letter of the existing Sargent trim, not just the finish, or the plates will not line up visually.
10) Will the Sargent 8241 hold up in a high traffic school corridor?
It is a heavy duty, Grade 1 mortise lock per ANSI/BHMA A156.13 Series 1000, with UL cycle testing at 16 million cycles (UL Verification ID V584148). That is the top commercial grade for mortise locks and is what most districts spec for corridor and classroom doors.
11) Should I use a mechanical classroom security lock like the Sargent 8241 or an electronic intruder lock?
The 8241 is fully mechanical, no batteries, no wiring, no programming. Lockdown depends on a staff member having the key. If you want credential based lockdown or audit trail instead, TownSteel's FME-4000 Series is an electronic intruder classroom mortise lock with RFID, Grade 1 heavy duty for 1-3/4 inch doors, and the FME-2000 Series is the Grade 1 RFID classroom version. Many districts mix the two: mechanical on most rooms, electronic where remote control matters.
12) Can I use the Sargent 8241-ET on a 2-1/2 inch backset residential mortise door, or is there a better fit?
The Sargent 8241-ET is built around a 2-3/4 inch backset and 1-3/4 inch door, for commercial use. For a 2-1/2 inch backset mortise body, Baldwin's 6301 entry/apartment and 6310 entry/storeroom lock bodies are the fit, offered knob by knob and lever by lever, with the 6301 listed for 1-3/4 inch and over and the 6310 for 1-3/8 inch and over. The right hand reverse lever version is the Baldwin 6310190RRLS.
13) Will a BEST 45HCA intruder mortise lock body work as a substitute for the Sargent 8241-ET?
It addresses the same opening type but is not interchangeable. The BEST 45HCAINL is a heavy duty mortise lockbody with intruder function, sold as a lock body rather than a complete escutcheon trim package. The Sargent 8241-ET is escutcheon trim for the 8200 Series with double cylinder classroom security intruder deadbolt function, ordered with a choice of LE1, LS, LW1 or WT escutcheon and A, B, E, F, J, L, P or W lever. Trim, cylinders and keying are not cross-compatible between the two platforms, so specify one brand's lock body and trim together.
14) What mortise lock functions should I order instead of the Sargent 8241-ET for offices, storerooms and restrooms in the same building?
The 8241-ET covers classroom security intruder deadbolt openings. For the other doors: storeroom is served by the Accentra 8805FL Grade 1 storeroom mortise lock or the Cal-Royal NM8080 Grade 1 storeroom lockset with interchangeable core option; office and entrance by the Cal-Royal NM8050 Grade 1 office/entrance lockset with auxiliary deadlatch or the Hager 3850E Grade 1 office mortise lock with lever and escutcheon on a 2-3/4 inch backset; and restrooms by the Cal-Royal NM8440 Grade 1 privacy lockset with deadbolt or the Hager 3840S Grade 1 privacy mortise lock. Passage openings take the Falcon MA101 Grade 1 heavy duty passage mortise lock.
15) Which mortise locks look like alternatives to the Sargent 8241-ET but will not secure a classroom door?
Several mortise products share the format without locking. The Schlage L0170 is a Grade 1 half dummy lever trim, non-keyed, and the Falcon MESC600DT is a dummy escutcheon lever trim for M9900 exit devices; Emtek's 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are dummy function as well. The Schlage PM010 Grade 1 passage latch mortise lock and TownSteel MRX-L-01 Grade 1 passage lockset latch but do not key. The Sargent 8241-ET is keyed, with double cylinder classroom security intruder deadbolt function.
16) I need the classroom door tied into an access control system. What replaces the Sargent 8241-ET?
For a wired or networked opening, the BEST 45HW Series is a heavy duty wired electromechanical mortise lock with 12V/24V operation, the Command Access ML190 Series is a heavy duty motorized mortise lock with field selectable EL/EU operation on 24VDC, and the Schlage L9092EU with 03A trim is an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit on 12/24VDC. Wireless options include the Schlage LEMD-GRW Grade 1 ENGAGE mortise lock with 125kHz proximity reader and the Alarm Lock DL1300NW Trilogy Networx wireless keypad mortise lock. The Sargent 8241-ET is a mechanical, non-electronic trim and lock.
17) For a behavioral health unit, is the Sargent 8241-ET the right choice or should I specify ligature resistant trim?
For ligature resistant openings, specify trim designed for it: the TownSteel MRX-A-01 is a Grade 1 heavy duty passage mortise lockset with ligature resistant satin stainless arch trim, the MRX-L-01 is the Grade 1 anti-ligature lever version, 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 1-3/4 inch door products in passage function. The Sargent 8241-ET uses lever handles and a keyed classroom security intruder deadbolt function.
18) What finishes does the Sargent 8241-ET escutcheon trim come in to match our other door hardware?
Sixteen finishes are offered: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized satin 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, BSP black suede powder coat and WSP white suede powder coat. Most school and institutional work standardizes on 26D or 32D.
19) Can I swap function later without changing the whole door prep on a Sargent 8200 mortise lock?
The 8200 Series covers 56 different functions, including electromechanical and security monitoring configurations, all built on the same mortise case footprint. Once the door is prepped for an 8200, you can change function later by changing the lock body and trim rather than recutting the pocket. That is the usual reason schools standardize a building on the series.
