Detex V4003CNxNS-628-36 – Frequently Asked Questions

1) Will the Detex V4003CNxNS fit a 2 inch narrow stile aluminum storefront door?
Yes. The V40xNS is built with extended rail length specifically to span stiles on 2 inch narrow stile doors, and it covers a 161 door prep with a field sizeable rail. It is not for wood doors, so on a hollow metal or aluminum storefront leaf you are in the right family.
2) What does the Key Retracts Latch function on the V4003CNxNS actually do?
With the CN pull trim, turning the key retracts the latch so the door can be pulled open from outside. Release the key and the latch returns, so the door relocks. There is no free-swinging lever, which is why this function is common on service and stairwell openings where authorized entry is by key only. Push the pad from inside and it always releases.
3) Do I have to specify handing for the Detex V40xNS, and what about the outside trim?
The device rail itself is non-handed, but the order still requires a hand for the trim and cylinder side: Right Hand Reverse or Left Hand Reverse. Exit doors in an opening swing out, which is why both choices are reverse bevel. You also pick a dogging option at the same time.
4) Which dogging option should I order on a fire rated V40xNS?
None of them. Mechanical dogging is not permitted on a fire rated exit device, so if you select the Fire Rated build, order it Less/No dogging. On non-rated openings you can take 1/8 turn hex key dogging or cylinder dogging to hold the latch retracted for daytime push-pull traffic, and Electric Dogging is offered as an electrified option.
5) Can the Detex V40xNS be used on a pair of doors?
Yes, on double doors fitted with a removable mullion. As a rim device the latch throws into a strike on the mullion, so a pair without a mullion needs a different type, either a surface vertical rod device or a concealed vertical rod unit such as the Hager 4601 narrow stile CVR.
6) What size V40xNS do I need for a 36 inch wide door?
Two rail lengths are built: 36 inch and 48 inch. Take the 36 inch for door leaves up to 36 inches wide and the 48 inch for wider leaves. The rail is field sizeable, so the 36 inch can be trimmed down for narrower openings.
7) Can I get a Detex narrow stile rim device with a built in alarm or delayed egress?
Yes. Beyond the plain mechanical build, the V40xNS is offered with a hardwired electric alarm, electric dogging, delayed egress, or a request to exit signal switch. Delayed egress and the RX switch are the two you want when the device has to tie into an access control or monitoring panel; the alarm version is the local-sounder answer for a door you just need to stop people using.
8) Is the Detex V40xNS available fire rated?
Both fire rated and non-rated builds are made, in either finish and either length. Fire rated is what you need on a labeled stair or corridor door; order it without mechanical dogging. If you want a fire rated narrow stile rim device from another line, the Adams Rite 3700 Series is a fire rated narrow stile option.
9) What is the closest Grade 1 narrow stile rim exit device to the Detex V4003CNxNS if I need a different brand?
The Detex V4003CNxNS is a Grade 1 narrow stile rim exit device. Comparable Grade 1 narrow stile rim devices include the Corbin Russwin ED4200, which is built for 1-3/4 inch doors and accepts outside trim, the TownSteel ED3700 in a 36 inch size, the TownSteel ED8900 in a 36 inch size, and the Falcon 19-R in a 36 inch exit only configuration. The Detex differs in that it is offered with a key retracts latch pull trim function, while the Falcon 19-R is exit only.
10) My door has a wide stile. Is the Detex V4003CNxNS still the right rim device?
No. The Detex V4003CNxNS is built with extended length to span stiles on 2 inch narrow stile doors. On a wide stile door, wide stile rim devices include the Von Duprin 22 Series at 36 inches, Grade 1 and non-handed for 1-3/4 inch doors, the Corbin Russwin ED5200 at 36 inches, Grade 1, which accepts trim, and the TownSteel ED9700 at 36 inches, Grade 1 heavy duty.
11) Will the V4003CNxNS latch into the strike I already have, and how secure is it?
The device uses a stainless steel 3/4 inch deadlocking Pullman type latch bolt and ships with Detex's mounting plate and strike locator, so the strike is set from the device rather than from a paper template. Expect to install the supplied rim strike rather than reuse an old one. The assembly withstands over 1,400 pounds of static pull force.
12) Can I change the outside trim or rekey the cylinder later without pulling the device off the door?
Yes. The V40xNS uses a modular design that accepts a range of outside trims and functions, and the outside trim can be changed or rekeyed without removing the device from the door. For a property manager standardizing keying across a building, that means the rail stays put and only the trim comes off.
13) Is the Detex V40xNS heavy duty enough for a school or hospital exit door?
It is a Grade 1 commercial device with a ribbed aluminum rail extrusion, high impact ABS and anodized surfaces, rated over 1,400 pounds of static pull force, and the angled end cap deflects impact away from the device. Detex positions the V40 as the value line within their range, so it is the economical Grade 1 rather than the top-tier build, but Grade 1 is the highest ANSI/BHMA durability class for exit hardware.
14) What fire rated rim exit device alternatives are there to the Detex V4003CNxNS?
The Detex V4003CNxNS is offered in fire rated and non-rated configurations. Other fire rated rim devices include the Adams Rite 3700 Series at 30 inches, Grade 1 narrow stile, the Dexter ED1000 Series fire rated Grade 1 rim device, the Arrow FS1250 at 32 inches, the Marks USA M9900F in 36 inch and 48 inch exit only sizes, and the Orca OED85 at 36 inches.
15) I only need a push bar with no outside trim. What is a simpler alternative to the Detex V4003CNxNS?
The Detex V4003CNxNS is configured with key retracts latch pull trim. If no outside trim is needed, exit only narrow stile devices include the BEST 2401 Series, which is non-handed exit only, the Falcon 1590EO at 42 inches for 1-3/4 inch doors, the Falcon 1790EO at 42 inches, and the Marks USA M8800 at 36 inches with panic protector end caps.
16) Is the SDC PSB560 pressure sense bar a substitute for the Detex V4003CNxNS?
No. The Detex V4003CNxNS is a mechanical rim exit device with a stainless steel 3/4 inch deadlocking Pullman type latch bolt. The SDC SureExit PSB560 at 36 inches is a pressure sense bar with tri-failsafe technology, and the SDC MSB550 at 36 inches is a mechanical switch bar that releases an electromagnetic lock. Both SDC bars fit narrow or wide stile doors but signal a separate locking device rather than latching into a rim strike themselves.
17) How does the Detex V4003CNxNS compare with the Stanley QED211 and Dormakaba QED200 narrow stile devices?
All three are Grade 1 narrow stile rim devices for non-wood doors. The Stanley QED200 Series device is heavy duty with hex key dogging, and the Dormakaba QED200 is a heavy duty 36 inch device supplied with a 7 ft rod. The Detex V4003CNxNS uses 1/8 turn hex key dogging and is ordered with a choice of hex dogging, cylinder dogging, or no dogging, and is configured with key retracts latch pull trim.
18) Is the Sargent 8504 a drop-in equivalent to the Detex V4003CNxNS with key trim?
Not exactly. The Sargent 8504 is a Grade 1 narrow design rim exit device with night latch function, where the key retracts the latch for entry. The Detex V4003CNxNS is a Grade 1 narrow stile rim device whose outside function is key retracts latch with pull trim, and its outside trims can be changed or rekeyed without removing the device. Confirm the trim style and cylinder arrangement the opening requires before treating one as the other.
19) What alternative works on a door thicker than standard if the Detex V4003CNxNS does not suit?
For thicker doors, the Adams Rite 8800 Series 30 inch narrow stile rim device covers 1-3/4 inch to 2-1/4 inch door thickness and is Grade 1 for non-wood doors, and the Dormakaba 9300 Series 48 inch wide stile device also covers 1-3/4 inch to 2-1/4 inch. Many other rim devices in this class, including the Falcon 19-R and Corbin Russwin ED4200, are specified for 1-3/4 inch doors only.
20) Are the Cal-Royal 5000 and 5500 rim devices equivalent to the Detex V4003CNxNS?
They are not the same class. The Detex V4003CNxNS is Grade 1 and built for 2 inch narrow stile doors. The Cal-Royal 5000 is a 36 inch wide rim exit device with a touch bar on a Grade 2 chassis, and the Cal-Royal 5500 is a 48 inch wide rim device with a push bar, also Grade 2. Both Cal-Royal devices are non fire rated and not wood door compatible.
21) If I need a concealed vertical rod device rather than a rim device like the Detex V4003CNxNS, what is available?
The Detex V4003CNxNS latches into a rim strike on the frame. For concealed vertical rod hardware, the Hager 4601 Series at 36 inches is a Grade 1 narrow stile concealed vertical rod exit device, and the Hager 4501 Series at 36 inches is the Grade 1 concealed vertical rod device with a wide stile pushpad.
22) What finishes does the Detex V4003CNxNS come in, and can I match existing storefront hardware?
Two: 628 brushed aluminum and 711 black aluminum. Both are available in 36 inch and 48 inch, rated or non-rated. 628 is the usual match for clear anodized aluminum storefront; 711 matches dark bronze and black anodized frames.
