Sargent 8249 LE1A 26D – Frequently Asked Questions

1) What does the Sargent 8249 security deadbolt function actually do when someone tries to leave the room?
The 8249 is a double cylinder security deadbolt function, meaning it takes a key on both sides to throw or retract the deadbolt. There is no thumbturn and no free egress from the inside once the bolt is thrown. That rules it out for most fire exit and life safety openings, where code requires egress without a key. Use it on storage rooms, mechanical spaces, vaults, and similar openings where nobody is inside when the door is locked.
2) Is the Sargent 8200 mortise lock fire rated for a 3 hour door?
Yes. The 8200 Series carries a UL 10C positive pressure fire rating up to 3 hours and is NFPA 80 compliant. It is also certified to ANSI/BHMA A156.13 Series 1000 Grade 1. Bear in mind the double cylinder 8249 function itself is a key-both-sides deadbolt, so verify it suits the egress requirements of the opening before putting it on a rated door in a means of egress.
3) Will the 8249 latch into the strike already in my frame?
The 8249 uses a 3/4 inch latchbolt throw off a 2-3/4 inch backset. If your existing strike was cut for an ANSI mortise lock at the same backset, the latch and deadbolt should pick up the existing prep. If you are replacing a bored lockset or a lock on a 2-3/8 inch backset, the frame strike and the door pocket both have to be reworked.
4) What do I need to choose besides the finish when ordering the Sargent 8249-ET?
Four things. Escutcheon style (LE1, LS, LW1 or WT), lever design (A, B, E, F, J, L, P or W), one of sixteen finishes running from 03 bright brass through 32D satin stainless to BSP black suede powder coat, and then the cylinder and keying. Cylinder choices are standard cylinder, less cylinder, 70 small format interchangeable core prep less core, or 60 large format interchangeable core prep less core. Keying is keyed different, keyed alike, or to a supplied key code. If you pick a less cylinder option, select None for keying.
5) Can I key this Sargent mortise lock into my existing building master key system?
The 8200 Series integrates with all Sargent key systems, including Degree, Signature, KESO and XC. For an existing IC core system, order the 70 small format interchangeable core prep or the 60 large format interchangeable core prep, both supplied less core, and drop in the cores your system already uses. For a facility standardizing keying across doors, keyed alike is an option at order, or supply your key code.
6) What is the closest Grade 1 mortise deadbolt alternative to the Sargent 8249-ET if the opening needs keypad access instead of keys?
The Sargent 8249 is a keyed, non-electronic Grade 1 mortise lock with a security deadbolt function operated by a double cylinder. For a keypad-driven deadbolt on a comparable Grade 1 opening, the Alarm Lock DL4500DB is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad, fitting doors 1-5/8 inch to 1-7/8 inch thick. The trade-off is straightforward: the Sargent needs a key on both sides and no power, while the DL4500DB is credential-managed at the door.
7) Is the Schlage LE Series mortise lock an equivalent grade to the Sargent 8249?
It depends on the LE model. The Sargent 8249 is Grade 1 with a UL 10C fire rating up to 3 hours. The Schlage LEBMB-ADD mobile-enabled mortise lock is Grade 2 with a 3 hour fire rating for privacy, office and apartment functions on 1-3/4 inch doors. The Schlage LEMD-GRW ENGAGE Series wireless mortise lock with 125kHz proximity reader and mobile-enabled deadbolt is Grade 1 with a 3 hour fire rating. If your spec calls for Grade 1, the LEMD matches and the LEBMB does not.
8) What mortise lock should I use instead of the Sargent 8249 on a behavioral health or ligature-resistant opening?
The Sargent 8249 uses escutcheon trim with a lever, which presents a projecting handle. For ligature-resistant openings, TownSteel offers the MRX-A-01 with satin stainless anti-ligature arch trim and the MRX-L-01 with an anti-ligature lever, both Grade 1 heavy duty passage function mortise locksets for 1-3/4 inch doors. Marks USA also offers the 5PDN, a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. Note these are passage functions rather than keyed deadbolts.
9) Can I use the Sargent 8249 on a 1-inch ornamental iron door, and if not what double cylinder mortise lock works there?
No. The Sargent 8249 is specified for 1-3/4 inch door thickness. For thin ornamental iron stiles, Marks USA offers the 21AC Unilock entrance double cylinder ornamental iron mortise lock with round knob and the 22AC entrance double cylinder ornamental iron mortise lock with round knob, both listed for 1 inch doors. Both keep the double cylinder keyed-both-sides arrangement the 8249 provides.
10) What should I substitute for the Sargent 8249 on an aluminum storefront with an Adams Rite deadlatch?
The Sargent 8249-ET is a 1-3/4 inch door mortise lock with escutcheon trim and is not intended for narrow storefront prep. The Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock with keypad is built for Adams Rite deadlatches. For glass door bottom rail applications, the Kaba Ilco BR Series is a glass door bottom rail lock.
11) Between the Sargent 8249-ET and the Accentra 8805FL, which suits a keyed-both-sides entry that must never be left unlocked from outside?
They handle the door differently. The Accentra 8805FL is a Grade 1 storeroom mortise lock with an Arcadia lever in the 8800 Series, so the outside lever stays locked and a key retracts the latch. The Sargent 8249-ET is a Grade 1 security deadbolt with double cylinder keying, meaning a key is required on both sides to throw or retract the bolt. Choose the 8805FL for keyed latch entry and the 8249 where a deadbolt secured from both faces is required - and confirm egress code allows double cylinder on that opening.
12) We use Baldwin mortise bodies elsewhere. Will a Baldwin 6301 or 6310 work where a Sargent 8249 is specified?
Check the backset first. The Sargent 8200 Series uses a 2-3/4 inch backset, while the Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies are 2-1/2 inch backset. The 6301 is listed for doors 1-3/4 inch and over, the 6310 for 1-3/8 inch and over, and both come in knob-by-knob and lever-by-lever arrangements such as the 6301LS and the 6310190RRLS right hand reverse. Different backset means different door prep, so they are not a drop-in for a Sargent 8200 mortise pocket.
13) Do I have to specify handing when I order this Sargent mortise lock?
Handing is field reversible on the 8200 Series lock body, so you do not have to stock a left and a right. That is useful for a property manager carrying spares across a building, since one lock covers either swing.
14) Is the Sargent 8249 tough enough for a high traffic commercial opening?
It is a heavy duty Grade 1 commercial mortise lock, and Sargent completed UL Cycle Above and Beyond testing on the 8200 Series at 16 million cycles under verification ID V584148. For schools, hospitals, and multi-tenant residential corridors, that is well past what a standard Grade 1 cycle requirement asks for.
15) I need a classroom or storeroom function instead of a deadbolt. What else is there in a Grade 1 mortise lock?
The 8249 is specifically the double cylinder security deadbolt function; the 8200 Series itself is offered in 56 functions, so the same lock body family covers classroom, storeroom and the rest. If you are open to other brands, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, the Cal-Royal NM8080 is a 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.
16) Is this Sargent lock electronic, and can I get an access control version on the same door prep?
The 8249-ET is a mechanical lock, not electronic. Electromechanical versions exist within the 8200 Series and run 12 to 24VDC with EcoFlex technology. If you want a standalone credential lock in a mortise prep instead, the TownSteel FME-2000 is a Grade 1 RFID mortise lockset for 1-3/4 inch doors, the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock, and the BEST 45HW is a wired electromechanical mortise lock with 12V/24V operation.
17) What is the difference between the Sargent 8249-ET and a BEST 45H mortise lock body?
The Sargent 8249-ET is supplied as a complete Grade 1 mortise lock with escutcheon trim, lever, and double cylinder keying, with escutcheon choices of LE1, LS, LW1, and WT. The BEST 45HCAC is a heavy duty mortise lock body in the 45H series with public entrance function and field reversible operation, and the 45HCAINL is a heavy duty 45HCA lock body with intruder function - those are lock bodies, so trim is specified separately. The Sargent is also field reversible for handing.
18) If I need electrified control on a mortise deadbolt opening instead of the mechanical Sargent 8249, what are the options?
The Sargent 8249 is a mechanical, non-electronic lock. For electrified mortise control, the Command Access ML190 is a heavy-duty motorized mortise lock with field selectable EL/EU operation, storeroom function, and 24VDC power. BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation. Schlage offers the L9092EU with an electric lock/unlock outside lever, keyed outside, request to exit, at 12/24VDC on 1-3/4 inch doors.
19) Looking for a non-keyed mortise lock with escutcheon trim like the Sargent 8249-ET for an interior door. What is comparable?
The Sargent 8249-ET is keyed with a double cylinder, so it is not the right choice where no key is wanted. The Hager 3810E is a Grade 1 passage mortise lock with escutcheon and 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, also 2-3/4 inch backset for 1-3/4 inch to 2-1/2 inch doors. Both share the 2-3/4 inch backset used by the Sargent 8200 Series.
20) Does a Kaba Ilco 185 Series mortise lock do the same job as a Sargent 8249?
They share a deadbolt function but differ in scope. The Kaba Ilco 185 Series is a mortise deadbolt with no handing requirement, sold in a single pack. The Sargent 8249-ET is a Grade 1 heavy duty commercial security deadbolt with double cylinder keying, escutcheon trim and lever, offered across eight lever styles and sixteen finishes. Check the trim and keying requirements of the opening before treating one as a swap for the other.
21) What is a simpler alternative to the Sargent 8249 for a bathroom or bedroom door that still uses a deadbolt?
The Sargent 8249 is a double cylinder security deadbolt keyed on both sides, which is not appropriate for privacy use. The Cal-Royal NM8440 is a Grade 1 heavy duty privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with 2-3/4 inch backset for doors 1-3/4 inch to 2 inch. Both give occupant-side control rather than key-both-sides security.
22) What is the difference between escutcheon trim and rose trim on a Sargent 8200 mortise lock?
The ET in 8249-ET means escutcheon trim: a single full plate carrying the lever and the cylinder, rather than separate sectional roses. Escutcheon covers more of the door face, which helps when you are replacing older trim and want to hide previous prep. The Sargent 7800/8200 template covers both sectional rose trims and escutcheon trims, so the underlying door prep is common between them.
23) I need a matching finish across a building. Does this Sargent lock come in satin chrome and stainless?
Sixteen finishes are offered, including 26D satin chromium plated over nickel and 32D satin stainless steel, the two most common commercial standards, plus 26 bright chrome, 32 bright stainless, 10B oil rubbed dark bronze, 15 satin nickel, 04 satin brass, and black and white suede powder coats. If your other openings are already 26D or 32D, you can match without changing hardware lines.
