Sargent 8290 EA 26D – Frequently Asked Questions

1) What does the classroom security holdback function on the Sargent 8290 actually do?
The 8290 is Sargent's classroom security holdback function, a double cylinder mortise lock with no deadbolt. Keyed cylinders on both sides mean a teacher can lock or unlock the outside lever from inside the room without stepping into the corridor, which is the whole point of a classroom security lock. The holdback part lets the latch be held retracted so the door can be left on free passage during normal hours.
2) Will the Sargent 8290 mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
That is exactly the prep it is built for. The 8290 uses a 2-3/4 inch backset and is specified for 1-3/4 inch door thickness, the standard commercial door. Latchbolt throw is 3/4 inch, so it engages a standard ANSI mortise strike.
3) Do I have to order the Sargent 8290 handed, left or right?
No. Handing is field reversible on the 8290, so one lock covers a left or right hand opening with no extra parts ordered. Useful if you are stocking spares for a building with mixed swings.
4) Can I put the Sargent 8290 on a fire rated classroom door?
Yes. The 8290 carries a UL 10C positive pressure fire rating up to 3 hours and is NFPA 80 compliant, and it is certified to ANSI/BHMA A156.13 Series 1000 Grade 1. For a rated opening you still need the matching fire rated frame, strike and closer.
5) What do I need to specify when ordering a Sargent 8290 besides the finish?
Four choices decide the part. Cylinder: standard cylinder, less cylinder, 70 prep for a small format interchangeable core less core, or 60 prep for a large format interchangeable core less core. Keying: keyed different, keyed alike, or a specific key code (choose None if you took the less cylinder route). Lever style: A, B, E, F, J, L, P or W. Rose: E at 3-1/16 inches, L at 3-1/2 inches, LN at 2 inches, or O at 2-3/4 inches.
6) Can I key the Sargent 8290 into my existing school master key system?
It works with all Sargent key systems, including Degree, Signature, KESO and XC. If your cores are Sargent already, order it keyed alike to the existing system or specify the key code. If your house key system is another brand, order the 60 or 70 interchangeable core prep less core and drop your own cores in.
7) What is the difference between the Sargent 8290 and a standard classroom mortise lock like the Cal-Royal NM8070 or Corbin Russwin ML2003?
Both of those are standard classroom function: keyed from the outside only, so staff have to open the door and key the corridor side to secure the room. The 8290 is classroom security holdback with cylinders on both sides, so the outside lever is locked from inside the classroom. The Cal-Royal NM8070 and the Corbin Russwin ML2003 are both Grade 1 for 1-3/4 inch doors, so they are direct swaps dimensionally if you only need the basic classroom function.
8) Can I use the Sargent 8290 on an access-controlled opening that needs to unlock electrically?
The Sargent 8290 is a mechanical, non-electronic mortise lock. For an electrically controlled opening, the Command Access ML190 is a heavy-duty motorized mortise lock with field selectable fail safe or fail secure operation on 24VDC in a storeroom function, and the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation. The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit on 12/24VDC for 1-3/4 inch doors.
9) What is a mechanical Grade 1 classroom mortise alternative to the Sargent 8290?
The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series listed for 1-3/4 inch doors, and the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset with an auxiliary deadlatch, also for 1-3/4 inch doors. Both are keyed mechanical classroom functions like the Sargent 8290, which is a Grade 1 mortise lock with a classroom security holdback function and a double cylinder keyed arrangement.
10) If the opening needs credentials instead of keys, what electronic classroom mortise locks are comparable to the Sargent 8290?
For credential-based classroom openings, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors, and the TownSteel FME-4000 is an electronic intruder classroom mortise lockset with RFID, also Grade 1 heavy duty for 1-3/4 inch doors. The Alarm Lock DL3500CR is a Grade 1 electronic classroom mortise lock with 300 user codes for doors 1-5/8 to 1-7/8 inch. The Sargent 8290 is a keyed mechanical lock and is not electronic.
11) Will a Baldwin 6310 mortise lock work in the same prep as the Sargent 8290?
No. The Baldwin 6310 entry/storeroom mortise lock body uses a 2-1/2 inch backset for doors 1-3/8 inch and over, while the Sargent 8290 is specified with a 2-3/4 inch backset for 1-3/4 inch doors. The different backset means a different mortise pocket location, so the two are not interchangeable in an existing prep.
12) How durable is the Sargent 8200 mortise lock for a high traffic corridor?
Heavy duty, Grade 1, and tested under the UL Cycle Above and Beyond program to 16 million cycles (Verification ID V584148). That is the class of lock you put on a main classroom or corridor door where a Grade 2 lockset would wear out.
13) Is there a classroom security mortise lock with a visual indicator instead of the Sargent 8290?
If staff need to see at a glance whether the room is secured, the Marks USA LA318GJ is a classroom security indicator mortise lockset, Grade 1, for 1-3/4 inch doors, supplied with an ANSI strike and a steel escutcheon measuring 8-1/2 x 2-3/4 x 7/16 inches. The Sargent 8290 does not carry an indicator, it relies on the inside cylinder for lockdown.
14) Does the Sargent 8290 come with rose trim or escutcheon trim?
Rose trim. You pick the rose diameter: LN at 2 inches, O at 2-3/4 inches, E at 3-1/16 inches, or L at 3-1/2 inches. If the existing doors have escutcheon plates and you want to cover old prep marks, a rose will not hide them, so match to what is on the door or plan on a repair plate.
15) Is the Accentra 8805FL a substitute for the Sargent 8290?
They are different functions. The Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series with an Arcadia lever, where the outside lever stays locked and is retracted only by key. The Sargent 8290 is a Grade 1 classroom security holdback mortise lock with a double cylinder arrangement, which allows the outside lever to be locked or held back by key from either side. Choose the 8805FL for a storeroom opening and the 8290 where classroom lockdown control is required.
16) What mortise lock covers the same classroom opening if intruder-function lockdown from inside is the priority?
The BEST 45HCA heavy duty mortise lockbody is offered with an intruder function, which locks the outside lever from the secure side. The Sargent 8290 achieves classroom lockdown through its classroom security holdback function with a double cylinder, keyed on both sides. The BEST unit is a lock body in the 40H Series; the Sargent 8290 is supplied as a complete lever set with rose trim in A, B, E, F, J, L, P, or W lever styles.
17) I only need a non-keyed mortise lock on a classroom corridor door. What is simpler than the Sargent 8290?
For a non-keyed opening, the Schlage PM010 is a Grade 1 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. The Hager 3810S is a Grade 1 passage mortise lock with rose trim and a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inch. The Sargent 8290 is keyed with a double cylinder and is the choice only where key control is needed.
18) Does the Sargent 8290 include a deadbolt, and what should I order if I need one?
The Sargent 8290 is a double cylinder classroom security holdback mortise lock with no deadbolt. If the opening needs a deadbolt, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes for doors 1-5/8 to 1-7/8 inch.
19) What mortise lockset should I specify for a behavioral health classroom instead of the Sargent 8290?
For anti-ligature openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim. The Marks USA 5PDN is a Grade 1 ligature resistant, ADA compliant hospital passage mortise push/pull paddleset in satin stainless steel. The Sargent 8290 uses conventional lever and rose trim in eight lever styles.
20) I need a classroom mortise lock that is fire rated for a 3 hour opening. How does the Sargent 8290 compare to electronic options?
The Sargent 8290 is UL 10C positive pressure fire rated up to 3 hours with NFPA 80 compliance. Among electronic mortise locks, the Schlage LEMD-GRW ENGAGE wireless mortise lock is Grade 1 with a 3 hour fire rating and a 125kHz proximity reader, while the Schlage LE Series LEBMB-ADD mobile enabled mortise lock carries a 3 hour fire rating at Grade 2 for 1-3/4 inch doors.
21) Is the Cal-Royal NM8050 or NM8080 the right pick over the Sargent 8290?
It depends on the opening. The Cal-Royal NM8050 is a heavy duty 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 Sargent 8290 is a classroom security holdback function, which is the specification when staff must lock or hold back the outside lever by key. The 8290 is also offered with 70 small format or 60 large format interchangeable core prep if you standardize on IC cores.
22) What finishes does the Sargent 8290 classroom security mortise lock come in?
Sixteen, covering brass and bronze (03, 04, 09, 10, 10B, 10BE, 10BL, 20D), nickel (14, 15), chrome (26, 26D), stainless (32, 32D) and two powder coats, BSP black suede and WSP white suede. For a school or healthcare corridor where the rest of the hardware is 626-type satin chrome, 26D is the match; 32D satin stainless is the usual pick alongside stainless push plates and exit devices.
23) Can I switch the function of a Sargent 8200 mortise lock after it is installed?
The 8200 Series covers 56 functions, including electromechanical, security and monitoring options, and functions can be switched on site. That matters for a facility standardizing on one lock body: you stock fewer parts and change the function of the opening as room use changes.
24) What is the difference between the Sargent 8290 and the Emtek Brisbane or Manhattan mortise entrance locksets?
The Emtek 3019 Brisbane and 3106 Manhattan mortise entrance locksets are dummy function, meaning there is no latch operation at all and they mount as pull trim only. The Sargent 8290 is a Grade 1 keyed classroom security holdback mortise lock with an operating latchbolt. They are not substitutes for one another.
25) Is the Schlage L0170 an option for a classroom door instead of the Sargent 8290?
The Schlage L0170 is a Grade 1 heavy duty non-keyed half dummy trim for 1-3/4 inch doors in the L Series, so it provides no latching or locking. Use it only on an inactive leaf or pull side. A classroom door that must be secured needs a keyed lock such as the Sargent 8290, a Grade 1 double cylinder classroom security holdback mortise lock.
