Detex 4008DN-628-36 – Frequently Asked Questions

1) Will a narrow stile rim exit device like the Detex 4008DN work on a pair of doors?
Yes, on a pair with a removable mullion. The Advantex 40 Series 4008DN is built for narrow stile single doors and double doors with mullions, because a rim device latches into a strike on the frame or mullion rather than at the head and sill. For a pair with no mullion and a clear opening, you need a vertical rod device instead, such as the Hager 4601 concealed vertical rod narrow stile exit device.
2) What does the Key Locks/Unlocks Lever function on the Detex 4008DN actually do?
With this function, the outside lever trim is controlled by the key: turn the cylinder to leave the lever free for entry, turn it back to lock the lever so only free egress from the inside works. It is the function you want when a staff door needs to be opened up during business hours and secured after. If you only need push-to-exit with no outside entry, an exit-only device such as the Corbin Russwin ED4200 narrow stile rim device is the simpler buy.
3) What do I have to specify when ordering the Detex Advantex 4008DN?
Four required selections plus the options. You pick dogging (hex dogging, cylinder dogging, or less/no dogging), strike type (99 surface or 98 semi-mortise), and handing (right hand reverse or left hand reverse). Then choose device size 36 inch or 48 inch, finish, rating (non-rated, fire rated, hurricane rated, or hurricane and fire rated), and any electrified option.
4) Can I get a fire rated narrow stile exit device with lever trim for a hurricane zone opening?
Yes. The Advantex 40 Series 4008DN is offered non-rated, fire rated, hurricane rated, or hurricane and fire rated, which is unusual in a narrow stile rim device. Note that fire rated labeled openings cannot use mechanical dogging, so specify less/no dogging on a fire rated build.
5) Does the Detex Advantex 40 Series come with delayed egress or a request to exit switch?
Both are factory options. The electrified choices are delayed egress, electric dogging, hardwired electric alarm, and a request to exit signal switch, or none for a straight mechanical device. Delayed egress and the RX switch are the two that integrators normally pair with an access control head end; the hardwired alarm is the local sounder version for a controlled door with no panel behind it.
6) What are the fire-rated alternatives to the Detex Advantex 4008DN?
The Advantex 4008DN can be ordered fire rated, and also in hurricane rated or hurricane and fire rated configurations. If you are cross-shopping dedicated fire-rated rim devices, the Adams Rite 3700 Series 30 inch is a Grade 1 fire-rated narrow stile device, the Dexter ED1000-R-F-EO is a Grade 1 fire-rated rim device, the Arrow FS1250 is a 32 inch fire-rated rim device for 1-3/4 inch doors, and the Marks USA M9900F comes in 36 inch and 48 inch fire-rated exit-only versions.
7) What is a comparable Grade 1 narrow stile rim exit device to the Detex 4008DN?
The Detex Advantex 4008DN is a Grade 1 narrow stile rim exit device. Close Grade 1 narrow stile peers include the Corbin Russwin ED4200, a Grade 1 narrow stile rim device in 36 inch for 1-3/4 inch doors; the TownSteel ED3700 and ED8900, both Grade 1 heavy duty narrow stile rim devices in 36 inch; and the Falcon 19-R, a Grade 1 narrow stile rim device in 36 inch. The difference is function: the 4008DN carries a key locks/unlocks lever function, while the ED4200 is exit only with provision for trim and the Falcon 19-R and TownSteel devices are offered exit only.
8) Is an SDC pressure sense bar or switch bar a substitute for the Detex 4008DN?
No, they solve a different problem. The Detex Advantex 4008DN is a mechanical Grade 1 rim exit device with a latch and strike that secures the door itself. The SDC PSB560 36 inch pressure sense bar and MSB550 36 inch mechanical switch bar fit narrow or wide stile doors but work by releasing a separate electromagnetic lock, so they need that lock to secure the opening. If you want electrified features on the Advantex itself, it is offered with delayed egress, electric dogging, hardwired electric alarm, or a request-to-exit signal switch.
9) If the Detex 4008DN is non-handed, why do I have to pick left or right hand reverse?
The device chassis itself is non-handed and field sizeable, but the order still takes a handing selection, right hand reverse or left hand reverse, so the outside lever trim and cylinder arrive oriented for your opening. Stand outside the door: on an outswinging door the hinge side tells you the reverse hand. Getting it wrong means a lever pointing the wrong way, not a device that will not mount.
10) I need to hold a storefront door unlocked during the day. Which dogging should I order on the Detex Advantex 40 Series?
Hex dogging is the low cost option and is fine where only maintenance staff will dog the device. Cylinder dogging lets you dog and undog with a key, which is what most property managers want when non-technical staff open the building. Electric dogging is also available as an electrified option so the device can be dogged from a schedule or a switch. On a fire rated door, choose less/no dogging.
11) Which strike do I order for the Detex 4008DN, 99 surface or 98 semi-mortise?
The 99 surface strike mounts on the face of the frame or mullion and is the straightforward retrofit choice, since it needs no frame routing. The 98 semi-mortise strike sets into the frame for a flatter, less snag-prone look on a storefront jamb but requires frame prep. Match the strike to what the existing frame will accept.
12) Do I have to pull the Detex Advantex device off the door to rekey the outside trim?
No. Outside trims on the Advantex 40 Series can be changed or re-keyed with the device still mounted, which is the reason locksmiths and MRO crews like it on rekey cycles and tenant turnovers. The angled end cap also deflects cart and door-stop damage away from the chassis.
13) My door has a wide 4 inch stile. Is the Detex 4008DN still the right device?
It will mount, but you are paying for a narrow stile chassis you do not need. On a wide stile hollow metal door a wide stile pushpad device gives more pad area, for example the Von Duprin 22 Series 36 inch non-handed Grade 1 device or the Corbin Russwin ED5200, both for 1-3/4 inch doors. Keep the narrow stile 40 Series for aluminum storefront and other narrow stile leaves.
14) Is there a simpler exit-only alternative if I do not need the keyed lever function of the Detex 4008DN?
Yes. The Detex Advantex 4008DN is configured for key locks/unlocks lever operation with outside trim. If the opening only needs egress with no outside control, the BEST 2401 Series is a narrow stile exit-only non-handed rim device, the Marks USA M8800 is a 36 inch narrow stile exit-only rim device, and the Falcon 1590EO is a 42 inch Grade 1 narrow stile exit-only device for 1-3/4 inch doors.
15) Is a concealed vertical rod device an alternative to the Detex 4008DN narrow stile rim device?
Only if the door and frame are prepped for it. The Advantex 4008DN is a rim device that latches to a surface or semi-mortise strike on the frame stop. The Hager 4601 is a Grade 1 36 inch concealed vertical rod narrow stile exit device and the Hager 4501 is a Grade 1 36 inch concealed vertical rod device with a wide stile pushpad; those latch top and bottom through the door and require concealed rod prep, so they are not a drop-in swap for a rim strike opening.
16) What is the closest alternative to the Detex 4008DN if I need a nightlatch function instead?
The Detex Advantex 4008DN uses a key locks/unlocks lever outside trim. If the opening calls for key retraction of the latch with no lever, the Sargent 8504 is a Grade 1 narrow design rim exit device with nightlatch function. Both are narrow stile Grade 1 rim devices; the difference is the outside trim behavior.
17) Are there Grade 2 rim exit devices that compete with the Detex Advantex 4008DN?
The Detex Advantex 4008DN is Grade 1 and tested beyond 1,000,000 cycles. Cal-Royal offers Grade 2 rim devices including the 5000 in 36 inch with a touch bar and the 5500 in 48 inch with a push bar, both heavy duty and non-fire-rated. If your spec or code review calls for Grade 1 panic hardware, the Cal-Royal Grade 2 devices will not satisfy it.
18) I need a 48 inch narrow stile rim exit device - what are my options besides the Detex 4008DN?
The Detex Advantex 4008DN is offered in 36 inch and 48 inch. Among 48 inch rim devices, the Dormakaba 9300 Series is a Grade 1 heavy duty wide stile device for 1-3/4 to 2-1/4 inch doors, the Corbin Russwin ED3200 is a Grade 1 48 inch crossbar wide stile device for 1-3/4 inch doors, the Marks USA M9900F is a 48 inch fire-rated exit-only device, and the Cal-Royal A9820 is a 48 inch exit-only device. Those are wide stile or crossbar designs, so the Advantex remains the narrow stile choice at that length.
19) How do Adams Rite interlocking rim devices differ from the Detex Advantex 4008DN?
Both are Grade 1 narrow stile rim exit devices for aluminum stile doors. The Adams Rite 8800 Series 30 inch uses starwheel interlocking, is non-fire-rated, is not wood door compatible, and fits 1-3/4 to 2-1/4 inch doors; the Adams Rite EX88 is a Grade 1 narrow stile interlocking rim device. The Detex Advantex 4008DN uses a stainless steel deadlocking Pullman-type latch bolt with either a 99 surface or 98 semi-mortise strike, and adds the keyed lever trim function.
20) Can I match the Detex 40 Series to existing dark bronze or black storefront hardware?
Ten finishes are offered: 605 polished brass, 606 brushed brass, 611 polished bronze, 612 brushed bronze, 613 oil rubbed bronze, 628 brushed aluminum, 629 polished stainless, 630 brushed stainless, 693 black painted, and 695 dark bronze painted. For anodized aluminum storefront, 628 and 695 are the usual matches. Exposed surfaces are finished over stainless steel with a PVD process.
21) Does the Detex Advantex 40 Series need a paper template for door prep?
No. Detex supplies a patented mounting plate and strike locator system in place of paper templates, which is what keeps the device and the strike in line on the first try. Full door prep templates, the installation instructions, and the parts list are published by Detex for the 40 Series.
