Falcon 8500NL US26D RHR – Frequently Asked Questions

1) Will the Falcon 8500NL night latch mortise lock work with my 24 Series exit device, or is it only for the 25 Series?
The 8500NL is a universal night latch mortise lock built for all 24/25 Series Falcon exit devices, so it fits either family. That is the point of the "universal" designation: one lock case part number covers the push pad devices across both series rather than a separate case per device model.
2) Do I have to order the Falcon 8500NL handed, and how do I tell LHR from RHR?
Handing is required. The 8500NL comes as LHR (left hand reverse) or RHR (right hand reverse) only, which is what you expect on an exit device: the door swings out toward you. Stand outside the opening, on the pull side. If the hinges are on your right and the door pulls toward you, it is RHR; hinges on the left, LHR. Get it backwards and the latch bevel faces the wrong way and will not catch the strike.
3) What does night latch function mean on a mortise exit device, and is it right for a back door staff use?
Night latch means the outside gets a key cylinder only, no lever or knob. Key retracts the latch to let someone in; without a key the outside is locked at all times. From the inside the push pad always releases for free egress. That is the usual choice for a rear service or staff entrance where you want a small group keyed in and everyone else kept out, but nobody trapped inside. If you need the outside to have a lever that a passage or classroom function unlocks, the 8500NL is the wrong case for you.
4) Is the Falcon 8500NL a complete exit device or just the lock case?
It is the mortise lock case for the device, not the whole exit device. The push pad rail, the outside trim or cylinder, and the strike are separate. Order it when you are replacing a failed lock case on an existing Falcon 24 or 25 Series device, or when you are building up a device and need the night latch function case. If you are buying a complete unit for a new opening, you want the exit device itself, not this part.
5) Will a Falcon 8500NL fit a narrow stile aluminum storefront door?
No. The 8500NL is a wide stile lock, sized for the deeper stile on hollow metal and wood commercial doors, and it will not mortise into a narrow aluminum storefront stile. For a narrow stile night latch mortise device, the Sargent 8304 is night latch function in narrow stile. Adams Rite also builds the 8400 Series life safety narrow stile mortise exit device for aluminum doors.
6) I need a fire rated mortise exit device for a stair door. Is the Falcon 8500NL the part?
Fire door assemblies need a device carrying a fire label, and the 8500NL is a night latch lock case rather than a labeled complete device. For a fire rated wide stile mortise exit device, ZenSupply carries the Adams Rite 3300 Series, listed fire rated for wood and hollow metal doors, and the Corbin Russwin ED5600AL, a Grade 1 three hour fire rated mortise exit device that takes passage or classroom lever trim. Note that a fire rated opening cannot use dogging, so plan the trim function accordingly.
7) What night latch mortise exit device works on a narrow stile aluminum door instead of the Falcon 8500NL?
Use the Sargent 8304 for a narrow stile opening. The 8304 is a Grade 1 night latch function narrow stile mortise exit device in the 8300 Series. The Falcon 8500NL is a wide stile night latch mortise lock, so it is prepped for a wide stile door face rather than a narrow aluminum stile. The Von Duprin 5575-3ft is another narrow stile mortise lock exit device, Grade 1, field reversible, for 1-3/4 inch doors, though it is a crossbar device rather than a night latch function.
8) Can the Von Duprin 8875, 9875 or 9475/9575 be used on the wood door where a Falcon 8500NL device sits?
The Von Duprin 8875-3FT and 9875-3FT are both Grade 1 wide stile mortise exit devices for 1-3/4 inch doors, non-handed, and both are listed as not wood door compatible. The Von Duprin 9475/9575 Impact Series is a Grade 1 wide stile mortise lock exit device with a recessed push pad and is not fire rated. On a wood door, the Adams Rite 3300 and 8300 Series are the wide stile mortise exit devices called out for wood and hollow metal.
9) Is the Falcon 8500NL Grade 1, and will it hold up on a high traffic entrance?
ANSI/BHMA Grade 1, the top commercial rating, and it is a commercial-only part. Grade 1 is the cycle and strength tier specified for heavy use openings, so it is the right class for an office lobby, a bank, a retail entrance, or an assisted living exit that gets worked all day.
10) What is a comparable wide stile night latch mortise exit device from another brand?
The closest cross-brand match on function and stile is the Sargent 8904, a Grade 1 wide stile mortise exit device in night latch function, with 24VAC/DC operation. Where the Falcon 8500NL is the lock case for an existing 24/25 Series push pad device, the Sargent 8904 is a complete device, so it is a swap for the whole opening rather than a part swap. Von Duprin's wide stile mortise options, the 9875 smooth case and the 9475/9575 Impact Series with recessed push pad, are also Grade 1 but are not night latch function.
11) Can I standardize a whole building on the Falcon 8500NL for exit doors?
Only for openings already running Falcon 24 or 25 Series push pad devices, since the case is built to that rail. Within that, standardizing is straightforward: one part number covers every 24/25 Series device, and you stock two handings and one finish to cover the fleet. Openings on other manufacturers' rails need that maker's own case, not this one.
12) Should I use a mortise exit device or a rim device on my exit door?
A mortise device puts the lock case inside a pocket routed into the door edge, so the door has to be prepped for it, but the latching hardware is concealed and the whole assembly sits flatter on the door. A rim device surface mounts with a strike on the frame stop and takes far less door prep, which is why it is the usual retrofit choice. Go mortise when the door is already mortise prepped, as it would be if you are replacing a Falcon 24/25 Series case like the 8500NL, or when the spec calls for it. If you are cutting a fresh opening and have the choice, rim is less work.
13) Is the Adams Rite 8300 a substitute for the Falcon 8500NL?
Not directly. The Adams Rite 8300 Series is a Grade 1 wide stile life-safety mortise exit device for wood and hollow metal doors, and it is not fire rated. It shares the Falcon 8500NL's Grade 1 rating and wide stile application, but the 8300 is a complete exit device while the 8500NL is the night latch mortise lock that fits Falcon 24/25 Series exit devices. Specifying the 8300 means replacing the whole device on the door, not swapping the lock case inside an existing Falcon device.
14) What is the difference between the Falcon 8500NL night latch and an exit only mortise device like the Detex 30 or BEST Precision 2301?
Function. The Detex 30 Series Advantex is a Grade 1 wide stile mortise lock exit device with a device only, exit only function and is listed as not wood door compatible. The BEST Precision 2301 is a 2300 Series mortise exit device, exit only, with heavy wrought construction. Exit only means egress from the inside with no outside entry. The Falcon 8500NL provides night latch functionality, which allows key entry from the outside while keeping the exit device's emergency egress.
15) The Falcon 8500NL is handed LHR or RHR. What comparable mortise exit device is non-handed?
The Falcon 8500NL is ordered in LHR left hand reverse or RHR right hand reverse. If the job would rather stock one non-handed part, the Von Duprin 8875-3FT and 9875-3FT are both Grade 1 wide stile mortise exit devices listed as non-handed for 1-3/4 inch doors, and the Von Duprin 5575-3ft is a Grade 1 narrow stile mortise lock exit device that is field reversible.
16) Which comparable mortise exit device accepts lever trim, which the Falcon 8500NL night latch does not provide?
The Corbin Russwin ED5600AL accepts passage or classroom lever trim, sold separately, and is a Grade 1 3 hour fire rated wide stile mortise exit device for 1-3/4 inch doors. The Falcon 8500NL is a night latch mortise lock, so outside access is by key rather than by lever. Where the specification calls for a classroom or passage lever on the outside of the door, the ED5600AL is the wide stile option.
17) Which comparable exit device offers electric latch retraction if the Falcon 8500NL opening needs to be tied to access control?
The Sargent 1256NB-8710G is a Grade 1 narrow stile 84 inch fire rated surface mount vertical rod exit device with electric latch retraction. It is a vertical rod device rather than a mortise lock, so it is a different door prep from the Falcon 8500NL night latch mortise lock. The Sargent 8904 is the wide stile night latch mortise device with 24VAC/DC operation.
18) What finishes does the Falcon 8500NL night latch mortise lock come in?
Six finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 622 matte black, 625 bright chrome, and 626 satin chrome. Each one is offered in both LHR and RHR, so handing never limits your finish choice. If you are matching a run of existing openings, 626 satin chrome is the common commercial default and 612 satin bronze the usual match for aged bronze hardware.
19) Is the Sargent 810 dummy trim an alternative to the Falcon 8500NL?
No. The Sargent 810 is a Grade 1 dummy pull exit device trim in the PE80 Series, with a dummy function, meaning it is a pull with no latching or locking action. The Falcon 8500NL is a night latch mortise lock that provides secure locking while maintaining the exit device's egress. If the opening needs outside key entry, the 810 does not provide it.
