Sargent 8289 EA 26D – Frequently Asked Questions

1) What does the holdback function on the Sargent 8289 mortise lock actually do?
The 8289 is the holdback function in Sargent's 8200 Series mortise line. Holdback means the latchbolt can be held retracted so the door stays free-swinging for a period, then returned to latching operation. It is a single cylinder, keyed lock with lever trim, so the key side controls the lock while the inside lever always retracts the latch for egress.
2) Will the Sargent 8289 latch into the existing ANSI strike on my commercial frame?
The 8289 uses a 3/4 inch latchbolt throw with a curved lip strike. On a standard commercial frame already prepped for a mortise lock strike, that throw engages normally. What decides the job is the door prep itself: this is a mortise lockbody, so the door needs a mortise pocket, not a cylindrical bore.
3) Can the Sargent 8289 mortise lock be used on a fire rated door?
Yes. The 8289 is UL 10C positive pressure fire rated up to 3 hours and NFPA 80 compliant, so it can go on a rated opening up to that duration. It is also ADA compliant, which matters for the lever trim on accessible routes.
4) Do I have to order the Sargent 8289 handed?
No. The 8289 lockbody is field reversible for handing, and the multifunction body also allows function changes on site. That means one lockbody covers left and right hand openings, which is why facilities standardizing on the 8200 Series can carry fewer spares.
5) What do I have to specify when ordering a Sargent 8289 mortise lock?
Four decisions. Cylinder: standard cylinder, less cylinder, 70 small format interchangeable core prep less core, or 60 large format interchangeable core prep less core. Keying: keyed different, keyed alike, a specific key code, or none if you are taking it less cylinder. Then lever style (A, B, E, F, J, L, P or W) and rose style (E at 3-1/16 inch, L at 3-1/2 inch, LN at 2 inch, or O at 2-3/4 inch). Finish is the last choice, from 16 options including 26D satin chrome, 32D satin stainless and BSP black suede powder coat.
6) Can the Sargent 8289 be master keyed into an existing Sargent key system?
It works with all Sargent key systems, including Degree, Signature, KESO and XC, so it drops into an existing Sargent masterkey hierarchy. Order it keyed alike, keyed different, or to a specific key code. If your locksmith is supplying cylinders or you run interchangeable cores, take it less cylinder or with the 60 or 70 core prep instead.
7) What is the closest Grade 1 mortise equivalent to the Sargent 8289 from another manufacturer if I need a storeroom function instead of holdback?
The Sargent 8289 is a Grade 1 heavy duty mortise lock with a holdback function. If the opening calls for storeroom instead, the Accentra 8805FL is a Grade 1 storeroom mortise lock in 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. Both keep the mortise prep and Grade 1 rating while changing the outside lever to a always-locked, key-retracting behavior rather than the 8289's holdback.
8) I need a classroom function mortise lock, not holdback - what should I order instead of the Sargent 8289?
The Sargent 8289 is built for holdback. For classroom function on a Grade 1 mortise prep, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with an auxiliary deadlatch, also for 1-3/4 inch doors. Both are mechanical keyed locks like the 8289 rather than electronic.
9) The Sargent 8289 description mentions 12 to 24VDC - is it an electrified lock, and what should I buy if I actually need access control?
The Sargent 8289 is catalogued as a mechanical, non-electronic keyed mortise lock with holdback function. If the opening genuinely needs electrified control, 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, 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.
10) For a behavioral health or corrections opening, is the Sargent 8289 the right mortise lock or is there an anti-ligature option?
The Sargent 8289 uses standard lever trim on E, L, LN or O roses and is not an anti-ligature design. For ligature-resistant openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in passage function, the MRX-A-01 is the same Grade 1 heavy duty passage lockset with ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 ligature resistant, ADA compliant hospital passage push/pull paddleset. All three are passage rather than the 8289's keyed holdback.
11) For a classroom security opening where staff must lock the door from inside, is the Sargent 8289 the right choice?
The Sargent 8289 is a single cylinder keyed mortise lock in holdback function, which holds the latch retracted rather than providing classroom lockdown. For lockdown, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with ANSI strike and steel escutcheon for 1-3/4 inch doors, and the TownSteel FME-4000 is a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID, also for 1-3/4 inch doors.
12) If I am standardizing a facility on Grade 1 mortise hardware, which alternatives to the Sargent 8289 cover the other functions in the same grade?
The Sargent 8289 covers holdback in Grade 1 heavy duty. Across the rest of a typical door schedule: Accentra 8805FL for Grade 1 storeroom, Corbin Russwin ML2003 for Grade 1 classroom, Cal-Royal NM8050 for Grade 1 office/entrance with auxiliary deadlatch, NM8440 for Grade 1 privacy with deadbolt, and Falcon MA101 for Grade 1 heavy duty fire-rated passage. Keying and trim styles differ by brand, so pick one manufacturer per facility if you want a single key system.
13) Is the Sargent 8289 an electrified lock, and does it need power?
The 8289 is catalogued as non-electronic in its mechanical holdback form, and the EcoFlex electromechanical functions in the 8200 line run on 12 to 24VDC with power savings quoted up to 96 percent. If you are buying it to tie into access control, confirm the electrified variant and wire it to a 12 to 24VDC supply before energizing.
14) Is the Sargent 8289 durable enough for a high traffic entry?
It is Grade 1 heavy duty, certified to ANSI/BHMA A156.13 Series 1000 Operational Grade 1, and completed UL's Cycle Above and Beyond test at 16 million cycles. That puts it at the top end for commercial corridor, school and healthcare traffic rather than a light commercial opening.
15) Should I use a mortise lock like the Sargent 8289 or a cylindrical lockset?
Pick the mortise 8289 when the door is already prepped with a mortise pocket or when you want Grade 1 heavy duty performance with a 3/4 inch latch and a full multifunction lockbody. A cylindrical lock such as the Schlage PC10 Grade 1 passage lock installs into a bored door and is the simpler swap where no mortise pocket exists. Mortise prep cannot be added to a bored door without machining, so the existing door decides this.
16) What other Grade 1 mortise locks could I use if the Sargent 8289 holdback function is not what my opening needs?
Holdback is a specific function. If you actually need the door to relock behind every user, the Accentra 8805FL is a Grade 1 storeroom mortise lock and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option. For a classroom opening look at the Corbin Russwin ML2003 Grade 1 classroom mortise lockset, and for passage only the Falcon MA101 Grade 1 heavy duty mortise passage lock is field reversible like the Sargent.
17) Which rose size should I pick on the Sargent 8289 to cover the old trim marks on my doors?
Four rose diameters are offered: LN at 2 inches, O at 2-3/4 inches, E at 3-1/16 inches and L at 3-1/2 inches. For a retrofit over an older lock, the L rose at 3-1/2 inches gives the most coverage of existing witness marks or oversized prep; the LN at 2 inches is the smallest and shows the most of the door face.
18) Can I order the Sargent 8289 without a cylinder so my locksmith can key it on site?
Yes. Choose Less Cylinder and set keying to None, and the lock ships prepped for your own mortise cylinder. If your facility runs interchangeable cores, order the 70 small format IC prep or the 60 large format IC prep, both supplied less core so you can drop in your existing cores.
19) What is a simpler, non-keyed alternative to the Sargent 8289 for an opening that does not need a cylinder?
The Sargent 8289 is a keyed single cylinder mortise lock. If the door only needs latching with no key control, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating. Both drop the cylinder and the holdback feature entirely.
20) What keypad or credential mortise lock can I use instead of the Sargent 8289 on a door that needs code access?
The Sargent 8289 is keyed only. For code or credential entry on a mortise prep, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function for 1-5/8 to 1-7/8 inch doors, 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. Note the door thickness ranges differ, so confirm the leaf before ordering.
21) Is a Schlage L0170 or an Emtek 3102 a substitute for the Sargent 8289?
No. The Sargent 8289 is a keyed single cylinder Grade 1 mortise lock with a working holdback latch. The Schlage L0170 is a Grade 1 mortise half dummy trim with a dummy function, and the Emtek 3102 Memphis is a dummy mortise entrance lockset. Dummy trim has no latch and no cylinder - it is surface trim for an inactive leaf, not a locking substitute.
22) I need a privacy mortise lock for a restroom instead of the Sargent 8289 holdback - what is comparable?
Holdback on the Sargent 8289 is not a privacy function. For restroom or bed/bath 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 Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 to 2 inches thick.
23) What is the difference between ordering the Sargent 8289 and a BEST 45H mortise lock body for an existing opening?
The Sargent 8289 is a complete heavy duty Grade 1 keyed mortise lockset ordered with lever style, rose style and finish, in holdback function. The BEST 45H is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCA with intruder function is likewise a heavy duty lockbody. A lock body alone is what you buy when you are reusing existing trim; the 8289 is specified with its trim.
24) Can I use a Baldwin 6310 mortise lock in place of the Sargent 8289 on a commercial opening?
They are not interchangeable in function. The Sargent 8289 is a commercial Grade 1 heavy duty holdback mortise lock. The Baldwin 6310 is an entrance/storeroom knob by knob mortise lock body on a 2-1/2 inch backset for doors 1-3/8 inch and over, and the 6301 is entrance/apartment function for doors 1-3/4 inch and over. The backset and function both differ, so the mortise pocket and keying scheme would not carry over.
25) What mortise lock should I use instead of the Sargent 8289 on an aluminum storefront or narrow stile door?
The Sargent 8289 is a heavy duty commercial mortise lockset with lever trim on roses up to 3-1/2 inches, sized for standard commercial doors. For storefront work, 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 an electronic pushbutton keyless mortise lock for wide stile doors, and the Kaba Ilco BR Series is a glass door bottom rail lock.
26) Does the Sargent 8289 come in a finish that will match the black or white hardware on the rest of my building?
Yes. Beyond the usual architectural finishes, the 8289 is offered in BSP black suede powder coat and WSP white suede powder coat. The rest of the range runs from 03 bright brass and 04 satin brass through 10B oil rubbed dark bronze, 15 satin nickel, 26D satin chrome and 32D satin stainless, 16 finishes in all.
27) Is there a mortise deadbolt alternative if I only need a bolt and not the Sargent 8289 lever set?
Yes. The Sargent 8289 is a lever-operated keyed mortise lock. If the opening needs only a bolt, the Kaba Ilco 185 Series is a no-handing mortise deadbolt, 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 inches thick. Neither provides latching or lever egress the way the 8289 does.
