Falcon 1792NL-OP/HB-OP 1790 Series Narrow Stile Rim Exit Device with Night Latch/Hold Back Function, 42"

Grade 1 Rim Exit Device for Narrow Stile Aluminum Doors

The Falcon 1792NL-OP/HB-OP is a 42" rim exit device from the 1790 Series, rated ANSI/BHMA A156.3-2001 Grade 1. Built for narrow stile aluminum door construction, it is not compatible with wood doors. The latch throw is 3/4", door thickness is 1-3/4", projection is 3-3/8", and the TD35 strike is supplied standard. The device is non-handed. An optional RX request-to-exit switch is available.

Features

Falcon 1792NL-OP/HB-OP 42IN US28 – Frequently Asked Questions

1) Does the Falcon 1792NL-OP/HB-OP need to be handed when I order it?
No handing to specify. Falcon lists the 1790 Series rim device as non-handed, so one part covers both left and right hand openings. That matters for a property manager stocking spares: a single model number sits on the shelf and goes on whichever door fails first.
2) What is the difference between the NL and HB cylinder functions on the Falcon 1792?
Two behaviors from the outside cylinder. Night latch retracts the latch momentarily so someone with a key can get in, without leaving the door unlocked. Hold back retracts the latch and keeps it held back, so the door stays free for a delivery window or a shift change until you key it back. On the 1792NL-OP/HB-OP you get both, which is why it suits a school or clinic entrance that runs open during the day and secure after hours. The device itself is exit only, so with the latch not held back, outside access is by key.
3) Does a strike come with the Falcon 1790 Series rim device or do I order it separately?
The TD35 strike ships standard with the device, so the frame side of the job is covered in the box. Latch throw is 3/4 inch, so the strike has to be set with the door in its closed position and the latch fully engaging that throw. If you are replacing an older device and reusing an existing strike, compare it against the TD35 prep before you drill: a mismatched strike is the usual reason a rim device chatters or fails to latch on a windy entrance.
4) Does the Falcon 1792 exit device come with outside trim or a pull?
It ships less trim. The 1792NL-OP/HB-OP is the device only, and the OP in the model stands for the optional pull, meaning the outside pull is a separate item you specify. A rim cylinder is also required to drive the night latch and hold back functions and is not part of the device. Budget those two lines on the order or the door will have no outside hardware when the crew arrives.
5) Can I get the Falcon 1790 exit device with a request to exit switch or electric latch retraction?
All three electrical options are order choices on the 1790 Series. RX, the request to exit switch, is a yes or no selection, and Falcon also publishes an RX switch retrofit kit covering the 1690, 1790 and 2390 devices, so an existing bar can be converted rather than replaced. EL, electric latch retraction, and ED, electric dogging, are each specified at order time as well. EL is what you want when an access control reader has to pull the latch for entry; ED is what you want when the device only needs to be held in a dogged, push-pull state on a schedule.
6) Is the Falcon 1790 Series rim exit device fire rated?
The 1792NL-OP/HB-OP is certified to ANSI/BHMA A156.3-2001 Grade 1, which speaks to cycle life and strength for high traffic, not to fire. For a fire rated opening, pick a device carried for that purpose: the Adams Rite 3700 Series is a fire rated narrow stile rim device, and the Dexter ED1000-R-F-EO and Orca OED85 are fire rated rim devices as well. Fire rated devices also have no dogging, which is a functional difference worth knowing before you swap one type for the other.
7) Should I use a narrow stile rim device or a wide stile one on my door?
The stile decides it, not preference. Narrow stile devices like the Falcon 1790 Series are built for the slim vertical rails of aluminum storefront doors, where a wide stile chassis simply will not land on the stile. On a hollow metal or wide stile aluminum door you have room for a wide stile device such as the Corbin Russwin ED5200 or the Von Duprin 22, both Grade 1 rim devices for 1-3/4 inch doors. Measure the lock stile before ordering; a wide stile device bought for a storefront leaf comes straight back.
8) Can I replace an old crossbar panic device on my storefront door with the Falcon 1792 pushpad?
Falcon lists the 1790 Series for retrofit of existing 2090 Series crossbar devices, so that swap is the intended one. Going from a crossbar to a pushpad also removes the gap a chain or coat hanger can be threaded through, which is a real problem on doors that get chained shut after hours. Verify the door is 1-3/4 inches and narrow stile aluminum before you pull the old bar, since the 1790 is a single thickness device.
9) Will this rim device work on a pair of doors with no center mullion?
No. A rim device latches into a strike on the frame or a mullion, so a pair of doors without a mullion has nothing for the Falcon 1790 latch to catch. The TD35 strike that ships with it has to mount to something fixed. For a mullion free pair you need vertical rod hardware, which latches at the head and the sill instead, such as the Hager 4601 concealed vertical rod narrow stile device. On a pair with a removable mullion, this rim device is the correct choice.
10) What is the closest narrow stile Grade 1 rim exit device to the Falcon 1792NL-OP/HB-OP if the Falcon is not the right fit?
The Corbin Russwin ED4200 is the nearest straight equivalent. It is a Grade 1 narrow stile rim exit device rated for 1-3/4 inch doors, the same door thickness the Falcon 1792NL-OP/HB-OP is built for, and it is likewise not wood door compatible. The Corbin Russwin is listed as exit only and accepts trim, while the Falcon 1792NL-OP/HB-OP is an exit only device ordered less trim with night latch and hold back cylinder function. Both are aluminum-door devices, so the stile prep on a storefront leaf carries across.
11) The Falcon 1792NL-OP/HB-OP does not fit - what fire rated rim device works on a 1-3/4 inch non-wood door?
The Arrow FS1250 is a fire rated 32 inch rim exit device for 1-3/4 inch doors, not wood door compatible, which is the same door thickness and substrate the Falcon 1792NL-OP/HB-OP is specified for. For longer openings, the Marks USA M9900F is a fire rated rim exit device, exit only with a panic protector end cap, in 36 inch and 48 inch. The Falcon 1792NL-OP/HB-OP is a Grade 1 narrow stile device at 42 inch, so on a labeled opening one of the fire rated devices is what to specify.
12) Is a Von Duprin 22 series a drop-in substitute for a Falcon 1792NL-OP/HB-OP?
No. The Von Duprin 22-3FT is a wide stile pushpad rim exit device, 36 inch, non-handed, Grade 1, for 1-3/4 inch doors. The Falcon 1792NL-OP/HB-OP is a narrow stile device. Both are non-handed Grade 1 rim devices on the same 1-3/4 inch door thickness, so the two get quoted against each other, but a wide stile chassis will not land on the narrow stile of an aluminum storefront leaf. Match stile type before anything else. For a wide stile hollow metal leaf the Von Duprin 22 is the appropriate device.
13) What narrow stile rim exit device has a night latch function comparable to the Falcon 1792NL-OP/HB-OP?
The Sargent 8504 is a night latch function narrow stile rim exit device, Grade 1, not wood door compatible. Its cataloged function is night latch. The Falcon 1792NL-OP/HB-OP carries a dual night latch and hold back cylinder function, where the night latch option retracts the latch without unlocking the device and the hold back option retracts and holds the latch back. If the opening only ever needs the outside cylinder to retract the latch for entry, the Sargent 8504 covers it; if a porter needs to hold the latch back during a delivery window, the Falcon hold back option is the one that does that.
14) Can I use an SDC pressure sense bar or switch bar in place of the Falcon 1792NL-OP/HB-OP?
Not as a like-for-like. The SDC PSB560 Series 36 inch is a pressure sense bar with tri-failsafe technology and the SDC MSB550 Series 36 inch is a mechanical switch bar with electromagnetic lock release; both fit narrow or wide stile. They release an electromagnetic lock rather than throwing a mechanical latch. The Falcon 1792NL-OP/HB-OP is a mechanical rim device with a 3/4 inch latch throw and a TD35 strike supplied standard. On an opening secured by a maglock the SDC bars are the correct hardware; on an opening that latches into a rim strike, the Falcon is.
15) What other narrow stile Grade 1 rim exit devices could I use instead of the Falcon 1790?
Several cross to it. The Corbin Russwin ED4200 is a Grade 1 narrow stile rim device for 1-3/4 inch doors and accepts trim. TownSteel ED3700 and ED8900 are both Grade 1 heavy duty narrow stile rim devices. The Detex 40 Advantex is narrow stile and rated extra heavy duty, a step up for an entrance getting abused. If the night latch function is the point, the Sargent 8504 is a narrow design rim device with a night latch function. None of those are drop-in for the Falcon prep, so treat them as alternatives for a new install rather than a bar swap.
16) Is the Falcon 1790 Series exit device tough enough for a busy school or hospital entrance?
Grade 1 under ANSI/BHMA A156.3-2001 is the highest commercial durability tier, and it is the grade specified for high traffic institutional openings. The 1790 uses cast metal cover plates and end caps rather than stamped covers, and all mounting screws are concealed, which removes the obvious point of attack on a public door. For an MRO buyer standardizing a building, a single non-handed Grade 1 model across every aluminum entrance keeps the spare parts list short.
17) What are the Grade 1 narrow stile rim alternatives to the Falcon 1792NL-OP/HB-OP for standardizing across a facility?
Within narrow stile Grade 1 rim devices for non-wood doors, the alternatives are the TownSteel ED3700 and ED8900, both heavy duty Grade 1 narrow stile rim devices at 36 inch, the Detex 40 Advantex, an extra heavy duty Grade 1 narrow stile device, and the Corbin Russwin ED4200 at 1-3/4 inch door thickness. The Falcon 1792NL-OP/HB-OP is ANSI A156.3-2001 Grade 1, non-handed, 42 inch. All of these are narrow stile, so any of them will address an aluminum storefront leaf; the differences that matter for a fleet are the duty level and the device length you need across the openings.
18) Is the Cal-Royal A9800 an equivalent to the Falcon 1792NL-OP/HB-OP?
They are not on the same grade. The Cal-Royal A9800 Series 36 inch rim exit device is exit only and heavy duty, carried as Grade 2, as is the Cal-Royal A9820 Series at 48 inch. The Falcon 1792NL-OP/HB-OP is ANSI A156.3-2001 Grade 1. If the drawing or the facility standard calls out Grade 1, the Cal-Royal A9800 and A9820 will not satisfy it, and the Falcon or another Grade 1 narrow stile device such as the TownSteel ED8900 is what to quote.
19) What is the difference between a Hager 4601 concealed vertical rod and the Falcon 1792NL-OP/HB-OP for a narrow stile opening?
The Hager 4601 Series 36 inch is a Grade 1 concealed vertical rod narrow stile exit device, so it latches top and bottom into the head and sill and the door must be prepped for concealed rods. The Falcon 1792NL-OP/HB-OP is a rim device that latches into a TD35 strike on the frame with a 3/4 inch throw and projects 3-3/8 inch off the door face. A rim device is the retrofit choice on an existing narrow stile leaf; concealed vertical rod is a door-prep decision usually made at the factory.
20) Is the Arrow 4800 Series a narrow stile alternative to the Falcon 1792NL-OP/HB-OP?
Yes, on the same door. The Arrow 4800 Series is a 36 inch narrow stile rim exit device, exit only, for 1-3/4 inch doors and not wood door compatible, which matches the Falcon 1792NL-OP/HB-OP on stile type, door thickness, exit only function, and substrate. The Falcon runs 42 inch and is non-handed with night latch and hold back cylinder function. Size the device to the door width, and if the outside cylinder needs to hold the latch back, that is the Falcon function.
21) What finishes does the Falcon 1792 narrow stile exit device come in?
Five: DC13 dark bronze anodized, DC35 black anodized, US28 clear aluminum anodized, US26 bright chrome and US26D satin chrome. The three anodized options are the ones that match typical aluminum storefront framing, so if you are adding a device to an existing entrance, match the frame finish rather than the other hardware. All five are offered both with and without the RX switch.
22) Which narrow stile rim device is rated above the Falcon 1792NL-OP/HB-OP for an abused high-traffic entrance?
The Detex 40 Advantex Series is cataloged extra heavy duty, Grade 1, narrow stile, and not wood door compatible. The Falcon 1792NL-OP/HB-OP is ANSI A156.3-2001 Grade 1 with cast metal cover plates and end caps and no openings for chains, which removes the coat hanger and chain tampering path on a storefront entry. Both suit a narrow stile aluminum leaf; the Detex 40 carries the extra heavy duty duty level, while the Falcon addresses abuse through the closed cast cover and concealed mounting screws.
