Sargent 8217 LE1A 26D – Frequently Asked Questions

1) Will the Sargent 8217 asylum function mortise lock fit a 1-3/4 inch door?
Yes. The 8200 Series mortise lock is built for 1-3/4 inch doors with a 2-3/4 inch backset, which is the standard commercial mortise prep. The door needs a routed mortise pocket plus cylinder and trim holes cut to the Sargent template for the 7800/8200 Series before the lock body goes in.
2) What does asylum function mean on a Sargent 8217 mortise lock, and when do I use it instead of a classroom lock?
Asylum function means both levers are always locked and a key is required on each side to retract the latch. That is why the 8217 is a double cylinder lock: no free egress, keyed in and keyed out. Use it where staff control passage in both directions, like behavioral health units, secure corridors, and utility rooms. If you need free egress from inside, this is the wrong lock. A classroom function lock, such as the Corbin Russwin ML2003, keys the outside lever and leaves the inside lever always free.
3) Is the Sargent 8217 mortise lock fire rated for a 3 hour opening?
It carries a UL 10C positive pressure fire rating up to 3 hours, along with ANSI/BHMA A156.13 Series 1000 Operational Grade 1. Cycle testing exceeds 16 million cycles under UL Verification ID V584148. That set covers most institutional stair, corridor, and cross-corridor openings where the door assembly itself is rated.
4) Will the Sargent 8217 latch into the strike that is already in my frame?
The 8217 uses a 3/4 inch latchbolt throw off a 2-3/4 inch backset. If the existing opening was prepped for an ANSI mortise lock at the same backset, the latch centerline and throw line up with a standard ANSI strike. Where you are replacing a bored lockset rather than a mortise lock, the frame strike and the door both have to be re-prepped; a mortise pocket is not a swap for a cylindrical prep.
5) Can the Sargent 8217 be keyed into our existing Sargent master key system?
Yes. The 8217 accepts all Sargent key systems, including Degree, Signature, KESO, and XC, so it master keys into an existing Sargent facility system. Order it with a standard cylinder, less cylinder if you are supplying your own, or with 70 small format interchangeable core prep or 60 large format interchangeable core prep when you stock and pin your own cores. Keying is specified as keyed different, keyed alike, or to a key code you supply.
6) Is a double cylinder asylum lock the right choice for a behavioral health room, or should I use a ligature resistant lockset?
The 8217 solves access control, not ligature risk. It is a Grade 1 heavy duty mortise lock with lever trim on both sides, and a lever is a projection a patient can loop. On patient rooms and bathrooms in psychiatric units, the anti-ligature trim is what matters: the TownSteel MRX-A-01 uses a Grade 1 heavy duty ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital push/pull paddleset that is ligature resistant and ADA compliant. Use the 8217 on staff-side doors, med rooms, and utility and mechanical spaces where key control in both directions is the requirement.
7) What is the difference between the Sargent 8217 and a storeroom function mortise lock?
Keying on the inside. A storeroom lock keys the outside lever and leaves the inside lever free to exit at all times, which is what the Accentra 8805FL and Cal-Royal NM8080 do. The 8217 is keyed on both sides, so nobody passes either direction without a key. If your inspector requires free egress on that opening, order storeroom instead. Reach for the 8217 only where a locked exit side is intended and permitted.
8) Can I use the Sargent 8217 on a 1-3/8 inch door or an aluminum storefront?
No on both counts. The 8217 is specified at 1-3/4 inch door thickness, so a 1-3/8 inch wood interior door does not have the stock for the pocket. Aluminum storefront stiles are too narrow for a standard ANSI mortise body; for glass door and narrow stile work look at the Kaba Ilco BR Series bottom rail lock or a narrow stile deadlatch application such as the Alarm Lock DL1300NW, which is built for Adams Rite deadlatches.
9) Does the Sargent 8217-ET come with a cylinder, or do I order that separately?
Cylinder is a required selection, not an automatic inclusion. Choose Standard Cylinder to get it complete, Less Cylinder if you are supplying your own, or 70 for small format interchangeable core prep and 60 for large format interchangeable core prep, both shipped less core. Because the function is double cylinder, a complete opening needs two cylinders or two cores, one per side. If you pick Less Cylinder, set keying to None; otherwise specify keyed different, keyed alike, or enter your key code on the order.
10) What is the closest equivalent to a Sargent 8217 asylum function mortise lock from another manufacturer?
For a double-cylinder institutional opening where the key must be used from both sides, the closest peer in a comparable heavy duty mortise lock body is the BEST 45HCAINL, which is a heavy duty mortise lockbody in the intruder function. The Sargent 8217-ET is a Grade 1 heavy duty mortise lock in the asylum/institution/utility function with double cylinder keying and lever trim. The BEST 45HCAINL is supplied as a lock body, so trim is specified separately, while the Sargent 8217-ET is configured with escutcheon trim in LE1, LS, LW1 or WT and a lever choice of A, B, E, F, J, L, P or W.
11) What mortise lock should I use instead of an asylum function lock on a classroom door?
Asylum function keeps both sides key-operated, which is not what a classroom egress opening wants. For classroom duty, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors with an auxiliary deadlatch, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset in the ML2000 Series for 1-3/4 inch doors. The Sargent 8217-ET stays with the asylum/institution/utility function and double cylinder keying.
12) Is a storeroom mortise lock the same as an asylum function lock?
No. A storeroom lock keys the outside only and leaves the inside free; 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 for 1-3/4 inch doors with an interchangeable core option. The Sargent 8217-ET is a double cylinder asylum/institution/utility lock, so the key controls both sides of the opening. Specify the function by which side needs key control, not by grade alone.
13) Do I have to specify handing when ordering a Sargent 8200 Series mortise lock?
No. The 8200 Series lock body is field reversible, so one lock covers left and right hand openings and you can change it on site. That cuts what a facility has to keep on the shelf: a single part number covers every swing in the building.
14) What lever and escutcheon options come on the Sargent 8217-ET, and how do I match the other doors in my building?
Escutcheon trim comes in LE1, LS, LW1, and WT. Lever choices are A, B, E, F, J, L, P, and W. Finishes run sixteen deep, from 26D satin chrome and 32D satin stainless for institutional corridors through 10B oil rubbed bronze, 04 satin brass, 15 satin nickel, and BSP black or WSP white suede powder coat. Pick the lever and finish already on your other 8200 Series openings and the new lock reads as part of the same set.
15) Is the Sargent 8217 an electronic or access control lock?
It is a purely mechanical, key operated mortise lock with lever trim. No wiring, no reader, no power supply. If the opening needs credentials or audit trail, look at electronic mortise locks instead: the TownSteel FME-2000 Series is a Grade 1 RFID mortise lockset for 1-3/4 inch doors, and the Dormakaba E-Plex E5086 is a Grade 1 pushbutton and card mortise lock. For a wired, powered opening, the BEST 45HW Series runs on 12V or 24V.
16) What is a simpler mortise lock for a behavioral health opening that does not need keyed control?
Where the door only needs to latch and pull, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in the passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function with ligature resistant arch trim. The Marks USA MAR5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. The Sargent 8217-ET is the keyed choice for the same environments, with double cylinder keying and lever trim.
17) What is the electronic alternative to a Sargent 8217 mortise lock for an institutional door?
For audit trail and code-based access on the same style of opening, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, and the FME-4000 is an electronic intruder classroom mortise lockset with RFID. The Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with 300 user codes and classroom function for 1-5/8 to 1-7/8 inch doors. The Sargent 8217-ET is a mechanical lock, keyed with a double cylinder and no electronics.
18) Which mortise lock matches an asylum function lock on a bathroom or bedroom door in a care facility?
Privacy openings take a different function. 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 inch to 2 inch doors. The Sargent 8217-ET is the double cylinder asylum/institution/utility lock for openings that stay under key control from both sides, and it uses the same 2-3/4 inch backset.
19) Are ornamental iron double cylinder mortise locks a substitute for a Grade 1 institutional mortise lock?
They are not interchangeable. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with a round knob, built for 1 inch doors. The Sargent 8217-ET is a Grade 1 heavy duty commercial mortise lock for 1-3/4 inch doors with lever trim and a 2-3/4 inch backset. Double cylinder describes the keying on both, but the door prep and duty level are different openings entirely.
20) Will the Sargent 8217 hold up in a high traffic corridor over a long service life?
Cycle testing exceeds 16 million cycles, verified under UL Verification ID V584148, on a heavy duty Grade 1 commercial lock body. That is the durability tier facilities specify for corridors, stairwells, and doors that swing hundreds of times a day. For comparison shoppers, most Grade 1 competitors in this class publish Grade 1 without a cycle count.
21) What should I order instead of an 8217 mortise lock for an office or entrance door in the same building?
For staff and administrative doors alongside institutional openings, the Cal-Royal NM8050 is a Grade 1 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 1-3/4 inch to 2-1/2 inch doors. The Sargent 8217-ET shares the 2-3/4 inch backset and escutcheon lever trim but carries the asylum/institution/utility function with a cylinder on both sides.
22) Will a dummy mortise trim work where an asylum function lock is specified?
No. Dummy trim has no latch and no cylinder, so it will not secure or hold a door closed. The Schlage L0170 is a half dummy trim, Grade 1 mortise non-keyed lever lock for 1-3/4 inch doors, and the Emtek 3102 Memphis is a mortise entrance lockset in the dummy function. Dummy trim is for an inactive leaf; the Sargent 8217-ET is a keyed lockset with a double cylinder and a 3/4 inch latchbolt throw.
