Detex V4008BNxNS-628-36 – Frequently Asked Questions

1) Can I put a Detex V40 narrow stile exit device on a wood door?
No. The V40xNS is not rated for wood doors, so on a hollow metal or wood opening you want a wide stile rim device instead. From the wide stile rim options, the Corbin Russwin ED5200 or the Von Duprin 22 are Grade 1 choices; if the door is wood specifically, the Adams Rite 3700 Series narrow stile rim device is listed as wood door compatible and fire rated.
2) What does the Key Locks/Unlocks Lever function on the Detex V4008BNxNS actually do?
The outside lever trim is controlled by the key: turn the key one way and the lever is locked (pull the door and nothing happens), turn it the other way and the lever stays unlocked for free passage until you key it back. It is the classic storefront setup where staff unlock the door in the morning and lock it at close. Push the bar from inside and you always get out. Trims are changeable or rekeyable without pulling the device off the door.
3) Do I need to order the Detex V40 exit device by hand?
The device itself is non-handed, but the order still asks for handing, Right Hand Reverse or Left Hand Reverse, because the keyed lever trim is handed. Stand outside the door: if it swings toward you and the hinges are on your right, it's Right Hand Reverse. Exit devices are always on out-swinging doors, so it is always a reverse hand.
4) Can I get the Detex V40xNS fire rated for a labeled stair or corridor door?
Both a Fire Rated and a Non-Rated version are offered, in either finish and either length. Order the fire rated one for a labeled opening. Note that fire rated exit devices cannot be dogged open, so on a labeled door specify Less/No dogging rather than hex or cylinder dogging.
5) What dogging options does the Detex V40 come with, and which should I choose?
Three choices, and it's a required selection: hex key dogging, cylinder dogging, or less/no dogging. Hex dogging is the standard 1/8 turn hex key setup and is fine for a back-of-house door where staff hold the allen wrench. Cylinder dogging keys the dogging to your cylinder so only keyholders can hold the latch retracted, which is what most property managers want on a public entrance. Choose less/no dogging on fire rated openings.
6) Can I use the Detex V40xNS on a pair of doors?
Yes, on double doors with a removable mullion. Being a rim device, the latch throws into a strike on the mullion, so a pair needs one. If you cannot have a mullion in the opening (wide equipment moves through it, for example), a rim device is the wrong type and you want a vertical rod device such as the Hager 4601 narrow stile concealed vertical rod, which latches at the head and sill instead.
7) What electrified options can I get on the Detex V40 exit device?
Four, plus a plain mechanical version. Hardwired electric alarm sounds locally when the bar is pushed, for a door that should not be used casually. Electric dogging lets access control retract the latch on a schedule for business hours. Request to exit sends a signal to the panel so a mag lock or alarm sees a legitimate exit instead of a forced door. Delayed egress holds the door for the code timed delay on a controlled exit. All four are available in either finish, either length, and rated or non-rated.
8) What is the closest Grade 1 narrow stile rim exit device to the Detex V40xNS if I need a different brand on the same aluminum storefront door?
The Detex V40xNS is a Grade 1 narrow stile rim exit device. Grade 1 narrow stile rim alternatives include the Corbin Russwin ED4200 in 36 inch, the TownSteel ED3700 in 36 inch, the TownSteel ED8900 in 36 inch, and the Falcon 19-R in 36 inch. All four are narrow stile rim devices carrying Grade 1, and all four are listed as not wood door compatible, the same as the V40xNS.
9) The opening has a wide stile door, not a 2 inch narrow stile - what Grade 1 rim device fits instead of the Detex V40xNS?
The V40xNS rail is extended to span stiles on 2 inch narrow stile doors, so a wide stile leaf calls for a wide stile chassis. Grade 1 wide stile rim options include the Von Duprin 22 in 36 inch, the Corbin Russwin ED5200 in 36 inch, the TownSteel ED9700 in 36 inch, and the DORMA 8300 Series.
10) Which narrow stile rim devices besides the Detex V40xNS come fire rated?
The V40xNS is offered in both Fire Rated and Non-Rated configurations in 36 inch and 48 inch. Among narrow stile peers, the Adams Rite 3700 Series in 30 inch is fire rated and Grade 1. Other fire rated rim devices include the Arrow FS1250 in 32 inch, the Dexter ED1000-R-F-EO in Grade 1, the Marks USA M9900F in 36 inch and 48 inch, and the Orca OED85 in 36 inch.
11) Is the SDC MSB550 switch bar a substitute for the Detex V40xNS?
No. The V40xNS is a Grade 1 mechanical rim exit device with a stainless steel 3/4 inch deadlocking Pullman latch bolt that latches the door itself. The SDC MSB550 in 36 inch is a mechanical switch bar that releases an electromagnetic lock, so the holding force comes from a separate maglock rather than a latch. The SDC SureExit PSB560 in 36 inch is likewise a pressure sense bar. Both are listed for narrow or wide stile.
12) The frame is prepped for concealed vertical rod, not a rim strike - what replaces the Detex V40xNS there?
The V40xNS is a rim device that latches into a rim strike and covers a 161 door prep. For a concealed vertical rod opening, the Hager 4601 Series in 36 inch is a Grade 1 narrow stile concealed vertical rod exit device, and the Hager 4501 Series in 36 inch is the Grade 1 wide stile pushpad version.
13) I need delayed egress on a narrow stile door - does anything else in the set do that, or is the Detex V40xNS the right pick?
The Detex V40xNS is offered with Delayed Egress, and also with Hardwired Electric Alarm, Electric Dogging, or a Request To Exit signal switch, in 36 inch and 48 inch, fire rated or non-rated. Among electrified peers, the Dormakaba E2103 with 4908A trim in 36 inch is furnished in an 08 classroom function, and the Securitron EMB electromechanical exit bar lists a 2-1/4 inch door thickness, so neither carries the same delayed egress arrangement.
14) Will the Detex V40 latch into my existing rim strike?
The V40xNS uses a stainless steel 3/4 inch deadlocking Pullman type latch bolt, which is the standard narrow stile rim throw, so it will engage a standard surface rim strike. Detex includes a mounting plate and strike locator system in place of paper templates, so the strike gets positioned off the device rather than off a measurement, and reusing an old strike hole is usually not worth the alignment risk.
15) Is the Detex V40 strong enough for a high traffic entrance, and is it Grade 1?
It is ANSI Grade 1, the top commercial rating, and Detex states the device withstands over 1,400 pounds of static pull force. Construction is heavy duty ribbed aluminum rail extrusion with high impact ABS and anodized surfaces. Detex positions the V40 as its Value Series, so it is the economical Grade 1 tier rather than the institutional flagship, which suits retail, office and multi tenant entrances.
16) What finishes does the Detex V40 narrow stile exit device come in, and will it match my black storefront?
Two finishes: 628 brushed aluminum, which matches clear anodized aluminum storefront, and 711 black aluminum for dark bronze or black anodized frames. Both are offered in 36 and 48 inch, fire rated or non rated, and with any of the electrified options, so a building standardizing on one finish across several entrances can keep it consistent.
17) What is a comparable narrow stile rim exit device if the Detex V40 doesn't suit?
Several Grade 1 narrow stile rim devices cover the same aluminum storefront application: the Corbin Russwin ED4200 (accepts trim, 1-3/4 inch door), the Falcon 19-R and 1590EO (exit only, 1-3/4 inch), the TownSteel ED3700 and ED8900, and the Adams Rite 8800 Series, which lists a 1-3/4 to 2-1/4 inch door thickness range for thicker leaves. All of those are non fire rated; for a labeled narrow stile opening the Adams Rite 3700 Series is the fire rated one.
18) Do I need to order outside trim separately for the Detex V4008BNxNS?
Yes. The 08 function is a keyed lever trim device, and the V40 is modular, accepting a variety of outside trims and functions. The lever trim and cylinder are specified alongside the device, and because trims change or rekey without removing the device, you can start exit only and add keyed lever trim later without pulling the rail off the door.
19) If I only need exit only and no keyed lever trim, is there a simpler alternative to the Detex V40xNS?
The V40xNS is configured for a Key Locks/Unlocks Lever function with outside trim. If the door needs no outside control, exit only narrow stile rim devices include the BEST 2401 Series, which is non-handed, the Falcon 1590EO in 42 inch, the Falcon 1790EO in 42 inch, and the Marks USA M8800 in 36 inch.
20) If the storefront needs a nightlatch instead of a key locks/unlocks lever, what narrow device covers that?
The Detex V40xNS is built for a Key Locks/Unlocks Lever function, where the key controls the lever. For key retraction of the latch only, the Sargent 8504 is a Grade 1 narrow design rim exit device with a Night Latch function.
21) Is a crossbar rim device like the CRL Jackson 1095 interchangeable with the Detex V40xNS?
They are different form factors. The V40xNS uses a ribbed aluminum push rail sized for 2 inch narrow stiles. The CRL Jackson 1095 in 48 inch is a crossbar rim panic device for wide stile doors and is exit only, and the Corbin Russwin ED3200 in 48 inch is likewise a wide stile crossbar device. A crossbar needs the wider stile and does not carry the keyed lever trim function.
22) Are the Cal-Royal 5000 and 5500 rim devices equivalent to the Detex V40xNS?
Not on grade or stile. The Detex V40xNS is Grade 1 and narrow stile. The Cal-Royal 5000 in 36 inch and the Cal-Royal 5500 in 48 inch are both listed as Grade 2 heavy duty wide rim devices, one with a touch bar and one with a push bar.
23) What narrow stile rim options are there if the Adams Rite starwheel interlocking design is not wanted?
The Adams Rite 3700, 8700 and 8800 Series in 30 inch and the Adams Rite EX88 all use an interlocking starwheel design. The Detex V40xNS instead uses a stainless steel 3/4 inch deadlocking Pullman-type latch bolt and is Grade 1 non-handed with field sizeable rails for 2 inch narrow stiles. The Adams Rite 8800 lists a door thickness range of 1-3/4 inch to 2-1/4 inch and is not wood door compatible.
24) Are templates and installation instructions available for the Detex V40?
Yes. Detex publishes installation instructions and a parts list for the Value Series V40, and the device ships with a patented mounting plate and strike locator system that replaces paper templates, which is what keeps the strike aligned on a narrow stile door where there is little margin for error.
