Key takeaways
- Each 8200 and 10X Line model number includes a function number, and the function tables below give what each listed function does.
- The 8200 catalog prints Grade 1 for operation and security "with all standard trims"; large and small format interchangeable core cylinders (LFIC and SFIC) do not meet Security Grade 1.
- Each 80 Series device type in the table below, from rim to concealed vertical rod, has its own number, catalog page, grade line and UL line.
- On several 80 Series device pages, SARGENT lists hex key dogging, which holds the push rail down with the latch retracted, as standard on "non fired rated devices".
Identify
Which SARGENT lock or exit device do I have?
Start with how the lock sits in the door. A mortise lock's body sits in a pocket cut into the door's edge, a cylindrical lock fits through a round hole bored through the door, and an exit device is a push bar across the door. The 7800 Series is the knob trim version of the 8200, and the catalog says 8200 lockbodies are dimensionally the same except for the through-bolt locations.

For how a mortise lock is built and how functions work on any brand, see the general commercial mortise lock guide.
| Line | What it is | Other lines on the same SARGENT page |
|---|---|---|
| 8200 Series | Lever mortise lock; the 7800 Series is the knob trim version | 7800, 7900, 9200 and M-9200 Series |
| 10X Line | Cylindrical lever lock, listed under bored locks | 11 Line, 7 Line, 6500 Series, 8X Line, 6 Line and DL Series |
| 80 Series | Rim, mortise lock and vertical rod exit devices | PE80, 90, 30, 20 and 5300 Series |

Fit and ratings
Will an 8200 or 10X lock fit my door, and what is it rated for?
The backset is how far the lock sits in from the door edge, and the stile is the door's vertical side band. On door thickness, each catalog and its product page read differently; the table gives both and this page doesn't pick one.
The 8200 catalog's grade line reads "Certified to ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and Security Grade 1 with all standard trims." The next line reads "Note: LFIC (Removable) Cylinders and SFIC Cylinders do not meet Security Grade 1 requirements." Its cylinder pages add: "When using Interchangeable Core Cylinders, the ANSI/BHMA Cylinder Grade determines the grade of the lock, even if the lock is certified ANSI/BHMA Grade 1 with a standard cylinder".
The 8200 fire listing line reads: "UL and cUL Listed to US and Canadian safety standards for A label 4 x 10 single and 8 x 10 double (3 hour fire door) and lesser class doors, stamped letter F and UL symbol on armored front indicate listing. Electrified functions are UL294 listed access control accessories."
The 10X Line catalog's grade and UL lines read "Certified ANSI/BHMA A156.2 (2022) Series 4000 — Grade 1" and "UL/cUL listed to US and Canadian safety standards for 3 hour doors up to 4' x 10' (double doors require 41- option)".
Both catalogs say any retrofit or other field modification to a fire rated opening can potentially impact the fire rating of the opening.

8200 functions
What does an 8200 function number mean?
An 8200 model number is the series plus a two-digit function, so an 8205 is the 8200 Series in the 05 function. Trim means the lever and its rose or escutcheon.
The catalog calls the Storeroom, Office, Classroom, Classroom Security and Exit Latch functions one multi-function 8200/7800 lockbody, which will accommodate the 04, 05 and 37 functions without additional parts, the 38 function by adding an additional cylinder, and the 06, 13, 31 and 36 functions by adding a Trim One Side Kit.
The 31 Utility, 36 Closet, 17 Asylum or Institutional and 24 Room Door functions carry the caution "not recommended for use on any door used for life safety egress", and the same caution heads the deadbolt-only page.
Eight lever designs (A, B, E, F, J, L, P and W) are standard on the 8200 Series only; the J, L and P have lever returns within 1/2" (13mm) or less of door face. Studio Collection levers, Coastal Series levers and freewheeling (FE) trim, where the outside lever swings freely in the locked mode, have their own pages.
The cylinder pages list SARGENT's Degree, Signature, XC, Keso and Keso F1 key systems, and large and small format interchangeable core options.
| Function | SARGENT's type name | ANSI No. | Key and thumbturn | Trim | Auxiliary deadlatch |

10X functions
10X Line functions, levers and cylinders
A 10X Line function is written as the line name, a G or U, and a two-digit function, such as 10XG05.
The levers are the B, L and P in solid cast zinc and four decorative levers (MD, MB, ND and MW), on the G or L rose. The rigid lever is standard and freewheeling levers are available, and there are pages for behavioral health (BHW) trim and visual status indicator (VSL) trim.
The cylinder pages list fixed core cylinders in conventional, Signature, XC, Keso and Degree versions, plus large and small format interchangeable cores.

| Function | SARGENT's type name | ANSI No. | Latch | Locking and release |
|---|---|---|---|---|
| 10XG04 | Storeroom or Closet | F86 | Deadlocking latch. Latch by lever inside or key outside. | Outside lever locked at all times. |

Electrified locks
Electrified 8200 and 10X locks: fail safe and fail secure
Both locks come in electrified versions, which their listing lines call access control accessories; the table gives what power does to the levers on each, in the catalog's words.
The 8200 catalog marks the 8273 with a caution: not recommended for use on any door used for life safety egress. Its EcoFlex section describes the lock as field configurable to fail-safe or fail-secure.
Of the 8200 electromechanical locks, the catalog says: "They meet ANSI/BHMA A156.13 Grade 1 requirements, are UL listed on fire doors, and satisfy industry standards for operating temperature, shock and fire hazard." The 10X Line's UL294 line reads "Listed as an Access Control Accessory (10XG70 & 10XG71)".
The 8200 electrified functions are available with a latchbolt monitor (LX-), request to exit (RX-) and motorized electric latch retraction (MELR, 56-), where the latchbolt retracts in 1/2 of a second with applied power and removing power allows the latch to project again. On the 10X Line, a request to exit switch that monitors the inside lever is the RX- option.
| Function | Lock | SARGENT's label | Catalog description | Power |

80 Series
80 Series exit devices by number
Each 80 Series device type has its own number and catalog page. Rim devices and the 8900 latch at one point. Vertical rod devices have rods on the door's surface or concealed inside it, and the table gives each one's latching.
On the concealed vertical rod pages, the NB- prefix is the version with less bottom rod. The 8700 can not be used less bottom rod, and its page points to the NB8700 for that.
Fire exit hardware takes a 12- prefix, which the options page defines as "UL Fire Label Exit hardware", and the catalog's chart of maximum door openings for fire doors lists the devices with that prefix.
Rail length follows door width. The 8800 page lists an E rail for 24" to 32" doors, F for 33" to 36", J for 37" to 42" and G for 43" to 48".

80 Series trim
8800 functions and outside trim
On the 8800, the outside lever trim is the 700 Series ET trim, ordered as a device number such as 8813 x ET_ with the lever design after the ET designation (for example ETL). The lever designs are the A, B, E, F, J, L, P and W, plus Coastal Series and Studio Collection levers.
The 73 and 74 functions have no cylinder override, and the 75 and 76 have cylinder override, where the key retracts the latch mechanically. For all four the voltage must be specified as 12VDC or 24VDC, and the actuator draw is 400mA inrush and 15mA continuous at 12VDC or 24VDC.

Dogging and options
Dogging and electric options on 80 Series devices
Dogging holds an exit device's push rail down with the latch retracted. The table lists the 80 Series dogging and electric options by order prefix.
The electric latch retraction page notes "HK- and 16- are not available for Fire Rated Doors", and of that option the catalog says: "The device can be dogged continuously on fire-rated devices that are tied into the building’s fire detection system."
Of electric dogging, the catalog says that when the device is de-energized or power is interrupted, the latch(es) will extend, and that manual hex key dogging is provided on non-fire rated devices.
The delayed egress compliance list includes the line "Conforms to NFPA 101 Special Locking Arrangements" and its operation list has the note "30 second delay available with written permission of Authority having Jurisdiction".
| Option | What it is | Power | Catalog notes |
|---|---|---|---|
| Hex key dogging | Dogging by hex key | — | "Hex key dogging standard on non fired rated devices", on the 8800, 8900, 8700, NB-8700 and MD8600 pages |

FAQ
SARGENT lock questions
Which SARGENT 8200 functions are fail safe and which are fail secure?
The catalog labels the 8270 and 8272 Fail Safe. It labels the 8271 and 8273 Fail Secure. On the 8270, power on locks the outside lever, and on the 8271 power on unlocks it.
What is the difference between a SARGENT 8800 and an 8900?
The 8800 is the 80 Series rim exit device, which the catalog describes as a single point rim latching device. The 8900 is the mortise lock exit device, with concealed single point guarded latching.
Does a fire-rated SARGENT 80 Series device have dogging?
Hex key dogging is listed as standard on "non fired rated devices", and the fire label option is not available with cylinder dogging or HK-. Of electric latch retraction, the catalog says: "The device can be dogged continuously on fire-rated devices that are tied into the building’s fire detection system."
