Detex 3008DM-628-90-36 – Frequently Asked Questions

1) What does the key locks/unlocks lever function on the 3008DM actually do?
Turning the key on the outside trim locks or unlocks the outside lever. When unlocked, anyone can pull the lever and walk in; when locked, the lever is dead and entry requires the key. Inside, the push pad always retracts the latch, so egress is never blocked regardless of how the outside is set. That is the difference between this and an exit-only device like the Falcon 25-M-EO or BEST Precision 2301, which have no outside entry at all.
2) Do I have to specify handing when ordering the Detex 30 Series mortise device?
Yes, handing is required on a mortise device because the latch and lock case are side-specific. The 3008DM is ordered Right Hand Reverse or Left Hand Reverse, which are the two handings that apply to an out-swinging egress door. Stand outside the door: if the hinges are on your right it is right hand reverse. The chassis itself is field-sizeable and non-handed for rail length, but the mortise lock handing is an order choice.
3) Will the Detex 3008DM latch into my existing strike, or do I need a new one?
The latch bolt is stainless steel with a 3/4 inch projection, anti-friction and deadlocking, so it needs a strike with matching pocket depth. Four strikes are offered with the device: 90 non-handed curved lip, 91 ANSI flat lip, 92 double door short open back, and 93 double door long open back. On a single door with an ANSI 4-7/8 inch frame prep the 91 flat lip is the usual pick; on a pair, the 92 or 93 open back strike mounts to the inactive leaf.
4) Can I use the Detex 3008DM on a pair of doors without a mullion?
Yes. A mortise device latches into the edge of the opening rather than the frame head, so a pair can be handled with the 92 double door short open back or 93 double door long open back strike mounted on the inactive leaf, no removable mullion needed. Order handing per leaf.
5) Is the Detex Advantex 30 Series mortise device fire rated?
Both ways. The 3008DM is offered as Fire Rated or Non-Rated, so you pick the version at order. Take the fire rated build on any labeled opening, and note that fire rated exit devices cannot have mechanical dogging, so specify less/no dogging on those. It is Grade 1 construction either way.
6) Can I get the Detex 30 Series mortise device with delayed egress or an alarm?
Yes, and the electrified option is a required order choice. Available: EA hardwired electric alarm, EX request-to-exit signal switch, EE delayed egress, EB electric alarm with battery, or None for a purely mechanical device. EE delayed egress is the one used where you want to hold an exit for the code-permitted delay on an alarm-monitored opening; EX is what you use to signal an access control panel that someone is pushing the bar so the door contact does not report a forced entry.
7) Will the Detex Advantex mortise device replace another brand's exit device on an existing door?
Detex states the Advantex 30 Series retrofits other manufacturers' devices with minimal door preparation. It also ships with a patented mounting plate and strike locator instead of a paper template, which is what keeps an existing prep usable and the new strike lined up. Mortise-to-mortise is the clean swap, so a wide stile mortise device such as a Von Duprin 8875 or 9875 is the realistic thing you are coming off of.
8) For a fire rated wide stile mortise opening, what are my choices besides the Detex 3008DM?
The Detex Advantex 3008DM is ordered with a rating option of either fire rated or non-rated, so the fire rated configuration covers a labeled opening directly. Other fire rated wide stile mortise devices include the Adams Rite 3300 Series, Grade 1 and fire rated, and the Corbin Russwin ED5600AL, a Grade 1 3 hour fire rated wide stile mortise device for 1-3/4 inch doors. The Von Duprin 8875, 9875 and 9475/9575 wide stile mortise devices and the Adams Rite 8300 are non-fire-rated.
9) The 3008DM will not work on my narrow stile aluminum storefront door - what mortise exit device should I use instead?
The Detex Advantex 3008DM is built for wide stile doors. For a narrow stile aluminum opening, the Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device intended for aluminum doors. Other narrow stile mortise options are the Von Duprin 5575-3ft narrow stile crossbar mortise lock device, Grade 1 and field reversible for 1-3/4 inch doors, and the Sargent 8304 narrow stile mortise device in night latch function.
10) What is a comparable wide stile mortise exit device to the Detex Advantex 3008DM from another manufacturer?
The Detex Advantex 30 Series 3008DM is a Grade 1 wide stile mortise exit device for commercial openings. Close wide stile mortise peers include the Von Duprin 9875-3FT smooth case wide stile mortise exit device, Grade 1 and non-handed for 1-3/4 inch doors, and the Adams Rite 8300 Series life-safety wide stile mortise device, also Grade 1. The Detex 3008DM differs in its function: key locks/unlocks the lever, where the 9875 is supplied as a push-pad mortise device and the Adams Rite 8300 is a non-fire-rated life-safety series.
11) I only need free egress with no outside trim - is there a simpler option than the Detex 3008DM?
Yes. The Detex Advantex 3008DM is configured for key locks/unlocks lever, which means outside lever trim and a cylinder. If the opening needs egress only, the Falcon 25-M-EO is a Grade 1 wide stile mortise exit device in exit only function for 1-3/4 inch doors, and the BEST Precision 2301 Series is an exit only mortise device with heavy wrought construction. The Corbin Russwin ED5600AL is a Grade 1 wide stile mortise device that can be used exit only or with passage or classroom lever trim ordered separately.
12) What dogging choices are there on the Detex 3008DM, and which should I pick?
Three: hex dogging, cylinder dogging, or less/no dogging. Hex dogging is set with an Allen wrench and is the low-cost option for a non-rated door you want to hold push-pull during business hours. Cylinder dogging uses a keyed cylinder so only keyholders can dog the device, which is what most schools and offices standardize on. Less/no dogging is required on fire rated openings.
13) I need exit devices that match the brass hardware on the rest of my building. What finishes does the Detex 30 Series mortise device come in?
Ten finishes: 605 polished brass, 606 brushed brass, 611 polished bronze, 612 brushed bronze, 613 oil rubbed bronze, 628 brushed aluminum, 629 polished stainless steel, 630 brushed stainless steel, 693 black painted, and 695 dark bronze painted. Exposed surfaces are PVD over stainless steel, which holds appearance better than a plated finish on a high-traffic door.
14) Should I use a mortise exit device or a rim device on my exterior metal door?
A mortise device like the Advantex 3008DM puts the lock case inside the door edge, so the latch is concealed and the door face stays clean, but it needs a mortise pocket cut into the stile and that is why it is a wide stile, non-wood application. A rim device surface mounts with a strike on the frame stop and needs far less door machining, which is why it is the easier retrofit when the door has no mortise pocket. If the door is already mortise-prepped, stay mortise. For a pair with no mullion, the mortise device works off an open back strike on the inactive leaf, while a rim pair normally needs a removable mullion or a vertical rod device such as the Sargent 1256NB-8710G surface vertical rod.
15) I want exit-only with no outside entry. Is the 3008DM the right Detex model?
Not if you truly want no outside operation. The 3008DM is the key locks/unlocks lever function, which means it takes outside lever trim. For exit only, the comparable options we carry are the Falcon 25-M-EO wide stile mortise exit device or the BEST Precision 2301 mortise exit-only device. If you want key retraction only from outside with no lever, that is a night latch function, such as the Sargent 8904 wide stile mortise device.
16) Does the Detex 3008DM include the outside lever trim?
The 3008DM is the device and mortise lock body with the key locks/unlocks lever function, and it ships with the mounting plate and strike locator plus the strike you select. Outside lever trim and the cylinder are separate specifications you need to add to complete the opening. Same situation as the Corbin Russwin ED5600AL, which is sold to accept passage or classroom lever trim that is not included.
17) What is the difference between the Detex 3008DM and the Von Duprin 9475/9575 for a wide stile door?
Both are Grade 1 wide stile mortise lock exit devices. The Detex Advantex 3008DM uses a touchpad-style Advantex 30 Series chassis with a patented mounting plate and strike locator, comes in 36 inch and 48 inch sizes, and is offered fire rated or non-rated. The Von Duprin 9475/9575 Impact Series uses a recessed push pad and is listed as non-fire-rated. A crossbar look instead is the Von Duprin 8875-3FT, a 36 inch non-handed wide stile crossbar mortise device.
18) Is the Sargent 810 or the Sargent 1256NB-8710G a substitute for the Detex 3008DM?
No. The Detex Advantex 3008DM is a wide stile mortise lock exit device with key locks/unlocks lever function. The Sargent 810 is dummy pull exit device trim, a pull with no latching function, so it cannot replace a mortise exit device. The Sargent 1256NB-8710G is an 84 inch fire rated surface mount vertical rod device for narrow stile doors with electric latch retraction, a different device type and latching arrangement entirely.
19) I want night latch function on a wide stile mortise device instead of key locks/unlocks lever - what should I order?
The Detex Advantex 3008DM is supplied in key locks/unlocks lever function. If the opening calls for night latch, where the key retracts the latch for momentary entry, the Sargent 8904 is a Grade 1 wide stile mortise exit device in night latch function with 24VAC/DC operation, and the Sargent 8304 is the narrow stile night latch equivalent.
20) Which mortise exit devices offer electrified options like delayed egress or request to exit the way the Detex 3008DM does?
The Detex Advantex 3008DM is ordered with an electrified option of none, EA hardwired electric alarm, EX request to exit signal switch, EE delayed egress, or EB electric alarm with battery. Among comparable devices, the Sargent 8904 wide stile mortise night latch device is offered with 24VAC/DC operation, and the Sargent 1256NB-8710G vertical rod device comes with electric latch retraction. The Falcon 25-M-EO and BEST Precision 2301 are mechanical exit only devices.
21) Is the Detex 3008DM tough enough for a high school or warehouse exit that gets abused daily?
It is built for that. Grade 1 commercial construction, described as super-heavy-duty for high-use and high-abuse openings, with a stainless steel anti-friction deadlocking latch and PVD-over-stainless exposed surfaces for corrosion resistance. Grade 1 is the top ANSI/BHMA durability tier for exit hardware and is what school, healthcare, and government specs normally call for.
