Sargent SGT-8223 03 – Frequently Asked Questions

1) Will the Sargent 8223 mortise deadbolt fit a standard 1-3/4 inch commercial door?
Yes. The Sargent 8223 is built for 1-3/4 inch door thickness with a 2-3/4 inch backset, which is the standard commercial mortise prep. If your doors are thicker or the existing pocket is cut to a 2-3/8 inch backset, this is not the body to order.
2) Does the Sargent 8223 need to be ordered left or right hand?
No handing to specify. The 8223 is a non-handed deadbolt body, so the same lock goes into a left or right hand opening. That makes it easier to stock one spare for a building with doors swinging both ways.
3) Is the Sargent 8223 a complete lockset with a lever, or just a deadbolt?
Deadbolt only. The 8223 is a mortise deadlock body with no latch and no lever or knob trim, so it provides no door pull and no passage latching. If you need a single mortise lock that both latches and locks for a classroom, look at a full classroom mortise lockset such as the Corbin Russwin ML2003 or the Cal-Royal NM8070 instead.
4) What does double cylinder mean on the Sargent 8223 classroom deadlock?
Double cylinder means the bolt is keyed from both sides, so there is no thumbturn and nobody throws or retracts the bolt without a key. That is the point in a classroom or corridor application where you want key control on both faces, but it also means egress depends on a key, so check your local egress code for the room before you specify it.
5) Is the Sargent 8223 deadbolt Grade 1 and fire door rated?
It carries ANSI/BHMA A156.13 Series 1000 certification, which is Grade 1 for mortise locks, and it is UL and ULC listed. That combination is what most school district and institutional specs call for on a corridor or classroom opening.
6) Can the Sargent 8223 be keyed into our existing Sargent master key system?
Yes. The 8223 takes Sargent conventional cylinders and works with the full range of Sargent key systems, including Degree, Signature, KESO and XC, so it can be brought into an existing campus masterkey rather than run as a separate key.
7) What is a Grade 1 classroom mortise lockset alternative to the Sargent 8223 when the opening needs a latch and lever, not just a deadbolt?
The Sargent 8223 is a deadbolt-only mortise unit with classroom function and double cylinder operation, so there is no latchbolt and no lever trim to operate. If the door needs a latching classroom lockset, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors. Those two latch and hold the door closed; the 8223 secures a door that is latched by something else.
8) Is there a mortise deadbolt equivalent to the Sargent 8223 from another brand?
The closest mechanical counterpart is the Kaba Ilco 185 Series mortise lock, which is a deadbolt function unit supplied with no handing, matching the 8223's non-handed deadbolt-only arrangement. The Sargent 8223 is a Grade 1 classroom deadlock with double cylinder keying and a 4-7/8 inch no-lip strike as standard. Confirm keyway and cylinder requirements on either before ordering, since the 8223 is built around Sargent key systems.
9) If a school wants keypad access instead of key-only control, what replaces the Sargent 8223?
The Sargent 8223 is key-operated from both sides with a double cylinder and no electronics. For code-based entry with classroom function, the Alarm Lock DL2700CR Trilogy T2 is a Grade 1 electronic mortise lock with classroom function for 1-5/8 to 1-7/8 inch doors, and the DL3500CR is a Grade 1 electronic mortise classroom lock carrying 300 user codes over the same door thickness range. For an electronic deadbolt rather than a latching lock, the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and privacy keypad.
10) What should I use instead of the Sargent 8223 if the classroom needs lockdown from inside the room?
The Sargent 8223 is keyed from both sides with a thumbturn inside to retract the bolt. For intruder-style lockdown functions, the BEST 45HCA heavy duty mortise lockbody is offered with Intruder function, and the TownSteel FME-4000 Series is a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID for 1-3/4 inch doors. The Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors with an ANSI strike and steel escutcheon, which adds visual status at the door.
11) What strike comes with the Sargent 8223 mortise deadbolt?
Every configuration ships with the 4-7/8 inch no-lip flat strike, part 78-0034, as standard. That is the common ANSI strike size for a hollow metal frame prep. There is no lipped strike option on the 8223, so if your frame needs a lip to protect the jamb edge you will be sourcing that separately.
12) We want an electronic classroom lock instead of a keyed deadbolt. What else is there?
The 8223 is mechanical and key operated only. For a keypad or credential based classroom opening, the Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock with classroom function for 1-5/8 to 1-7/8 inch doors, and the TownSteel FME-2000 is a Grade 1 classroom mortise lockset with RFID for 1-3/4 inch doors. The Alarm Lock DL4500 is the electronic mortise deadbolt if you want to stay deadbolt-only.
13) Is the Sargent 8223 deadbolt strong enough for a high traffic school corridor?
The bolt is one-piece hardened steel, and the lock is certified to the Grade 1 mortise standard, which is the top performance tier for commercial door hardware. It is catalogued as commercial-only hardware, not residential, and is intended for educational, healthcare, government and multi-tenant work.
14) What mortise locks look like substitutes for the Sargent 8223 but will not work on a classroom door?
Several mortise units in the same size class serve different purposes. The Schlage PM010 and Falcon MA101 are Grade 1 passage function mortise locks, non-keyed, so they provide no security at all. The Schlage L0170 is Grade 1 mortise dummy trim with no lock mechanism, as are the Emtek 3102 Memphis and 3104 Hamilton dummy entrance locksets. The Hager 3840S and Cal-Royal NM8440 are Grade 1 privacy function units for bed and bath, keyless on the inside. The Sargent 8223 is a classroom deadbolt with double cylinder key control from both sides.
15) For an office or storeroom door rather than a classroom, what mortise lock takes the place of the Sargent 8223?
The Sargent 8223 is configured for classroom protocol as a deadbolt-only unit. For a keyed latching lock on an office or storeroom opening, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch and the NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, both for 1-3/4 inch doors. The Accentra 8805FL is a Grade 1 storeroom mortise lock supplied with an Arcadia lever, and the Hager 3850E is a Grade 1 office mortise lock, non-keyed, with lever and escutcheon on a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors.
16) Can credential-based access replace the Sargent 8223 on a school door that also needs to work on an access control system?
The Sargent 8223 is fully mechanical with double cylinder keying. Networked and credential options include the TownSteel FME-2000 Series, a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, the Schlage Electronics LEMD-GRW Grade 1 ENGAGE wireless mortise lock with 125kHz proximity reader and 3 hour fire rating, and the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock with keypad for Adams Rite deadlatches. Each requires credential and system planning the 8223 does not.
17) Will a Baldwin 6301 or 6310 mortise lock body work where the Sargent 8223 is specified?
They are prepped differently. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies use a 2-1/2 inch backset, the 6301 for doors 1-3/4 inch and over and the 6310 for doors 1-3/8 inch and over. The Sargent 8223 uses a 2-3/4 inch backset for 1-3/4 inch doors, so the mortise pocket and cylinder centerline do not line up between them. Match the backset in the existing door prep before choosing.
18) What finishes does the Sargent 8223 deadbolt come in to match our other door hardware?
Twelve finishes are offered: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized satin bronze, 10BE and 10BL dark oxidized satin bronze, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, plus BSP black and WSP white suede powder coat. For most school and office work 32D satin stainless is the one that matches existing hardware.
19) Is the Marks USA 21AC or 22AC double cylinder mortise lock an alternative to the Sargent 8223?
Both are double cylinder units, but the doors differ. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks listed for 1 inch door thickness. The Sargent 8223 is a Grade 1 classroom deadlock for 1-3/4 inch doors on a 2-3/4 inch backset. Use the ornamental iron bodies on narrow gate and iron doors and the 8223 on standard commercial wood or hollow metal openings.
